Description

  The present invention relates to a transmission device that transmits video data and the like, a display device that can display video data in three dimensions, a transmission / reception system that can transmit and receive video data, a transmission / reception method, a display method, a transmission method, and video control. It relates to a remote control that can do.

  Conventionally, it has been known that the appearance of an object in the object space can be changed and displayed by changing the gaze position. The gaze position is a position where the parallax on the display disappears.

  Therefore, when generating two different images that generate binocular parallax, the images recognized by both the left and right eyes are made to coincide so that the object closer to the gaze position has no parallax. Conversely, the image recognized by both the left and right eyes is shifted so that parallax is induced as the object is farther from the gaze position.

  As a result, with respect to the object in the vicinity of the gaze position, the object in front of the gaze position appears to jump out, and the object in the back from the gaze position appears to be pulled back.

  For example, FIG. 48 shows an object 4802, an object 4803, and an object 4804 displayed on the display screen 4801, and shows a case where the gaze positions are set as a gaze position 4805, a gaze position 4806, and a gaze position 4807, respectively. Yes. It is assumed that the viewer is looking at the direction of the arrow.

  First, when the gaze position 4805 is set, the object 4802, the object 4803, and the object 4804 are all pulled down and displayed.

  When the gaze position 4806 is set, the viewer displays the object 4802 and the object 4804 as they jump out, and the object 4803 is displayed while being pulled back.

When the gaze position 4807 is set, the object 4802, the object 4803, and the object 4804 are all popped out and displayed. (For example, refer to Patent Document 1).
JP 2003-107603 A (page 14, FIG. 6)

  By the way, the appearance of the object by the above method depends on the relative position of the object from the gaze position with the gaze position as a reference.

  Therefore, for example, when a plurality of objects are close to each other, it is difficult to display only a specific object while making it stand out and obtain an easy-to-view video.

In addition, for example, when objects are arranged at various places in the perspective, it is difficult to obtain an easy-to-view video because the viewer's eyes are tired due to the severe perspective difference.

  Accordingly, in view of the above problems, the present invention provides a display device that performs stereoscopic display with high visibility for a viewer.

Information regarding the depth direction of the object data of the object displayed on the display means with a predetermined object other than the object can be changed.

  Further, based on the comparison result, the difference between the depth position of the object specified by the object specifying means and the depth position of the object displayed on the display means by a predetermined object other than the object specified by the object specifying means is narrowed. Thus, the information regarding the depth direction of the object data of the object displayed on the display means can be changed.

  Also, the comparison is performed so that the depth position of the object specified by the object specifying means is displayed in front of the depth position of the object displayed by the display means on a predetermined object other than the object specified by the object specifying means. Based on the result, the information about the depth direction of the object data of the object displayed on the display means can be changed.

  Further, the depth width of the object specified by the object specifying means is widened, or the depth width of the object displayed on the display means by a predetermined object other than the object specified by the object specifying means is narrowed. Information about the depth direction of the object data of the object specified by the object specifying means can be changed.

Also, the display is performed so that the depth position of the object specified by the object specifying means is displayed in front of the depth position of the object displayed by the display means for a predetermined object other than the object specified by the object specifying means. Information about the depth direction of the object data of the object displayed on the means can be changed.

  Further, the object is set so that the difference between the reference plane which is a plane extending in the vertical direction with respect to the depth direction and the depth position of the object displayed on the display unit with a predetermined object other than the object specified by the object specifying unit is narrowed. Information related to the depth direction can be changed among the object data of the objects displayed on the display means other than the objects specified by the specifying means.

  The object displayed on the display means includes one or more first objects and a second object included in the first object, and one or more first objects selected from the objects displayed on the display means. The object designating means for designating the first object other than the first object designated by the second object included in the first object designated by the object designating means or the object designating means is provided. Information about the depth direction of the second object included in the object can be changed.

  Further, the control unit can change information regarding the depth direction of the object data of the object in accordance with the degree of attention of the object displayed on the display unit.

  In addition, the object displayed on the display means is an object constituting a program table, and the control means changes information on the depth direction of the object data of the object so that the depth width of the object becomes wider as the audience rating of the program is higher. it can.

  Further, the object displayed on the display means is an object displayed in a hierarchical structure, and the control means sets the object data of the object in the lower hierarchy so that the depth width of the object in the lower hierarchy is wider than the object in the upper hierarchy. You can change the information about the depth direction.

  In addition, when the acquisition unit acquires an operation code indicating a processing procedure for changing information related to the depth direction of the object data, the control unit can change information related to the depth direction of the object data of the object based on the operation code.

  According to the present invention, it is possible to provide a display device that performs stereoscopic display with high visibility for a viewer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
The first embodiment shows an example in which the depth width of an object displayed stereoscopically is changed and displayed. In particular, in order to improve the visibility of a designated object, the depth width of an object other than the designated object is changed and displayed.

  First, the receiving apparatus 101 according to the first embodiment will be described with reference to FIG. The reception apparatus 101 includes a reception unit 102, a separation unit 103, a decoder 104, a video signal processing unit 105, a control unit 106, an input unit 107, a storage unit 108, a 3D conversion unit 109, and a display unit 110.

  For example, the receiving device 101 is a television, and of course, a television that can receive various programs such as connecting to a cable television network to receive a program, or connecting to a telephone line to provide an internet connection or communication karaoke. May be. Further, the receiving apparatus 101 does not necessarily have to satisfy the above-described configuration. For example, the STB (set top box) that does not have the display unit 110 and needs to be connected to another device that newly performs display. It may be.

  The receiving unit 102 receives and demodulates a signal transmitted from the transmitting device, and outputs the demodulated signal to the separating unit 103.

  The separation unit 103 separates the video signal and audio signal included in the signal output from the reception unit 102 and the additional information such as information related to the program. Then, the video signal and the audio signal are output to the decoder 104, and the additional information is output to the control unit 106.

  The decoder 104 decodes the video signal output from the separation unit 103 and outputs the decoded video signal to the 3D conversion unit 109. Also, the audio signal output from the separation unit 103 is decoded and output to an audio output unit (not shown) such as a speaker via an audio signal processing unit (not shown).

  The 3D conversion unit 109 performs predetermined processing on the video signal output from the decoder 104 and outputs the processed signal to the video signal unit. However, the 3D conversion unit 109 performs the predetermined process when the video signal includes information for displaying a stereoscopic video such as object data.

  In addition to storing the additional information from the control unit 106, the storage unit 108 also stores setting values stored in advance in the receiving apparatus 101 and object data that is displayed on the display unit 110 in response to a request from the viewer. ing. For example, object data of a menu object for setting as shown in FIG. 16 described later, a broadcast program list object as shown in FIG. 31, and a multi-screen list object as shown in FIG. 37 are stored.

  The input unit 107 outputs an object ID for designating a specific object from the objects constituting the display video to the control unit 106.

  In addition to outputting the additional information from the separation unit 103 to the storage unit 108, the control unit 106 outputs the object ID output from the input unit 107 to the 3D conversion unit 109. Further, control is performed so that the receiving unit 102 receives a desired video signal.

  The video signal processing unit 105 creates a display video based on the object data output from the 3D conversion unit 109. The display video is, for example, video displayed on the display.

  The display unit 110 displays the display video created by the video signal processing unit 105. In addition, as a method of displaying the display image in three dimensions, as shown in the above method, the viewer can wear glasses with red and blue color filters and display the left-eye and right-eye images. There are a method of alternately switching the left and right eye images on the display without using dedicated glasses for displaying 3D images, and a method of providing slits. Also good.

  By the way, the object data handled by the receiving apparatus 101 of the first embodiment is composed of an object ID 201 for identifying an object and object display information 202 for displaying the object, as shown in FIG. It shall be.

  The object display information 202 is represented as a set of dots whose positions are specified using an absolute coordinate system including an x-axis, a y-axis, and a z-axis set in the object space.

  More specifically, the object 602 in FIG. 6 described below is composed of eight dots 605, 606, 607, 608, 609, 610, 611, and 612. Position information of eight dots 605, 606, 607, 608, 609, 610, 611, and 612 is shown.

As for the coordinate system, as shown in FIG. 3, the lower left of the display to be displayed is set as the origin 301, the x axis is set to the right side of the screen, the y axis is set to the upper direction of the screen, and the z axis is set to the forward direction of the screen. . In addition, the dot whose z-axis coordinate value is expressed as a positive value is displayed so that the viewer who looks at the display screen appears to jump out before the display screen.
By the way, in describing the embodiment of the present invention, the depth direction is a negative direction with respect to the z axis, the near side is the positive direction with respect to the z axis, and the far side is with respect to the z axis. Suppose that the direction is negative.

  The depth position of the object is the maximum value among the z-axis coordinate values obtained from all the dots in the object display information.

  Further, the depth width of the object is a value obtained by subtracting the minimum value of the z-axis coordinate values from the maximum value of the z-axis coordinate values obtained from all the dots in the object display information.

  An object can be constituted by a set of a plurality of objects. For example, an object representing a landscape includes an object representing a tree and an object representing a mountain.

  Next, a processing procedure performed by the receiving apparatus 101 according to the first embodiment will be described, and its flow is shown in FIG.

  First, the viewer inputs an object ID for designating a specific object from the input unit 107 such as a remote controller (step S401).

  Next, in order to narrow the depth width of an object having an object ID other than the input object ID, a numerical value of a magnification value is input from the input unit 107 (step S402). The magnification value is a ratio of the depth width of the object after the depth width is reduced with respect to the depth width obtained from the object display information of a certain object. For example, when the magnification value is set to 0.5, the depth width of the object is reduced to half.

  Next, the control unit 106 outputs the magnification value and the object ID input by the input unit 107 to the 3D conversion unit 109 (step S403).

  The 3D conversion unit 109 changes the object display information based on the magnification value so as to narrow the depth width of the objects constituting the video except for the object having the object ID received from the control unit 106 (step S404).

  The video signal processing unit 105 creates a stereoscopic video based on the changed object display information (step S405).

  The display unit 110 displays the stereoscopic video created by the video signal processing unit 105 (step S406).

  In step S402, if no magnification value is input from the viewer for a certain period of time, the processing may be continued based on a preset magnification value.

  For example, after the viewer inputs an object ID of a specific object from the input unit 107, the control unit 106 interrupts the process until a numerical value is input to the magnification value from the viewer. When the interrupted time exceeds a predetermined set time, the control unit 106 may acquire a magnification value set in advance in the storage unit 108 and output it to the 3D conversion unit 109.

  Further, as described above, a preset magnification value may be used without waiting for input of the magnification value. In that case, in the processing procedure shown in FIG. 4, step S402 is not performed, and step S403 is performed after step S401.

  A case where step S401 is not performed is also conceivable. For example, in a sixth embodiment described later, an example in which a specific object can be selected from a transmission device is shown, and it is not always necessary to specify a specific object on the reception device.

  Next, the processing performed by the 3D conversion unit 109 in the processing procedure shown in FIG. 4 will be described in detail, and the flow is shown in FIG.

  When the object ID of the object specified by the input unit 107 is received from the control unit 106, the 3D conversion unit 109 reads the object ID of the object output from the decoder 104 in order to form a display video (step S501).

  It is confirmed whether there is an object ID that matches the specified object ID among the object IDs of all the read objects (step S502).

  If there is no object that matches the specified object ID (N in step S502), the process performed by the 3D conversion unit 109 is terminated (step S503).

  If there is an object that matches the specified object ID (Y in step S502), the process is continued. Then, an object that does not match the designated object ID is selected (step S504), and the maximum value of the z-axis coordinate value, that is, the depth position of the object is determined from the z-axis coordinate values of all the dots included in the object display information of the object. Obtained (step S505).

  Then, the z-axis coordinate value of each dot constituting the object selected in step S504 is changed. For example, when the depth position of the object obtained in step S505 is represented as D and the magnification value is represented as M, the changed z-axis coordinate value of the dot is expressed as (D−M × (D−z-axis coordinate of the dot before change). Value)) (step S506).

  Thereafter, it is checked whether or not the object IDs of all the objects output from the decoder 104 have been confirmed (step S507).

  If the object IDs of all objects displayed on the display video with objects that do not match the designated object ID are confirmed (Y in step S507), the processing performed by the 3D conversion unit 109 is terminated (step S503). ). Note that all objects refer to objects 603 and 604 other than the selected object 602 when FIG. 6 described later is used. If the object IDs of all the objects have not been confirmed (N in step S507), the process returns to step S504 and continues.

  Next, the first embodiment will be described based on the display image shown in FIG.

  FIG. 6 shows a display video displayed on the display screen 601, and the display video is composed of an object 602, an object 603, and an object 604. Further, the position of each object according to the x-axis coordinate and the z-axis coordinate when the display image is viewed from above is shown.

  In order to identify each object, the ID of the object 602 is “001”, the ID of the object 603 is “002”, and the ID of the object 604 is “003”.

Also, it is assumed that each object is composed of eight dots, and the coordinate values of the eight dots constituting the object 602 are dot 605 (1, 3, 5), dot 606 (1, 3, 7), dot 607. (4, 3, 5), dot 608 (4, 3, 7), dot 609 (1, 5, 5), dot 610 (1, 5, 7), dot 611 (4, 5, 5), dot 612 (4, 5, 7). The depth width of the object 602 is 7−5 = 2 because it is a value obtained by subtracting the minimum value of the z-axis coordinate value from the maximum value of the z-axis coordinate value among all the dots constituting the object 602. .

  Similarly, coordinate values of eight dots constituting the object 603 are dot 613 (7, 3, 1), dot 614 (7, 3, 3), dot 615 (10, 3, 1), dot 616 (10 3, 3), dot 617 (7, 5, 1), dot 618 (7, 5, 3), dot 619 (10, 5, 1), dot 620 (10, 5, 3). At this time, the depth width of the object 603 is 3-1 = 2.

  The coordinate values of the eight dots constituting the object 604 are dot 621 (12, 3, 5), dot 622 (12, 3, 6), dot 623 (15, 3, 5), dot 624 (15, 3, 6), dots 625 (12, 5, 5), dots 626 (12, 5, 6), dots 627 (15, 5, 5), and dots 628 (15, 5, 6). At this time, the depth width of the object 604 is 6-5 = 1.

  First, the viewer inputs an object ID for designating a specific object from the input unit 107 from a remote controller or the like. Here, it is assumed that “001”, which is the object ID of the object 602, is output from the remote controller in order to specify the object 602.

  Next, in order to narrow the depth width of the object 603 and the object 604, a numerical value of a magnification value is input from a remote controller or the like. In the first embodiment, the magnification value is 0.5.

  In addition, although it wrote that selection of a specific object and numerical value input of a magnification value were performed from a remote control etc., it may be other than the above method. For example, a method using a remote controller 701 as shown in FIG. 7 can be considered. The remote controller 701 includes a power button 702, a channel switching button 703, a cross object selection button 704, and an operation handle 705. The viewer can select a specific object from the objects constituting the video by using the cross object selection button 704. Further, by operating the operation handle 705 in the arrow direction 706, the numerical value of the magnification can be set while confirming on the screen. A method using a remote controller 801 as shown in FIG. 8 is also conceivable. The remote controller 801 includes a power button 802, a channel switching button 803, a cross object selection button 804, and a sphere 805. A specific object can be selected by the object selection button 804 and settings can be performed while rotating the sphere in the arrow direction 806. You may do it.

  Further, regarding the display image shown in FIG. 6, when the viewer operates the operation handle 705 or the sphere 805, the display image becomes an image as shown in FIG. In addition, about the structure of FIG. 9, about the thing which is the same structure as what was shown in FIG. 6, the number attached | subjected in FIG. 6 is used.

  In FIG. 9, the selected object 602 is displayed on the display screen 601, the objects 603 and 604 constituting the display video, and the control status display object 901 is displayed on the lower right.

  The control status display object 901 is a graph display 902 for easily grasping the magnitude of the magnification value. The control status display object 901 displays “narrow” 903, “original width” 904, and “wide” 905, and “original width” 904 is a point where the magnification value is 1. In FIG. 9, the graph display is in the middle of “original width” 904 and “narrow” 903, and it can be confirmed that the graph is displayed slightly narrower than the original width.

  An arrow 906 is displayed on the display screen 601 so that the selected object 602 can be grasped instantaneously.

  Note that the control status display object 901 may be displayed numerically instead of indicating the magnitude of the magnification value as described above. The control status display object 901 may be displayed only when the magnification value is set by the operation handle 705 or the sphere 805, or the depth width of the objects constituting the display video other than the selected object may be displayed. It may be displayed during the control to be narrowed.

  Note that the operation handle 705 or the sphere 805 may be set to the numerical value of the difference value described in the second embodiment, and in this case, the control status display object 901 indicates the numerical value and degree of the difference value. There may be.

  The arrow 906 may be other means as long as it can display the selected object 602 instantaneously. For example, the selected object 602 is scaled to represent the shape in the control status display object 901. It may be displayed.

  Next, the control unit 106 outputs “001” that is the ID of the object 602 and the magnification value 0.5 to the 3D conversion unit 109.

  The 3D conversion unit 109 reads the object IDs of the object 602, the object 603, and the object 604 constituting the video, and identifies an object having the object ID “001” and an object having no object from them.

  Of the objects 603 and 604 that do not have the object ID “001”, first, the coordinate values of eight dots are read from the object display information of the object data of the object 603. Then, the maximum value is obtained from the z-axis coordinate values of the eight dots. In this case, the maximum value is 3.

  Since the maximum value of the z-axis coordinate value obtained from all the dots of the object display information is the depth position of the object, the depth position of the object 603 is 3.

  Next, the z-axis coordinate values of the eight dots constituting the object 603 are changed so as to narrow the depth width of the object 603 without changing the depth position of the object 603. For example, if the depth position of the object is represented as D and the magnification value is represented as M, the z-axis coordinate value of the dot after change is based on (D−M × (D−z-axis coordinate value of dot before change)). change.

  As an example of the change, since the z-axis coordinate value of the dot 617 constituting the object 603 is 1, the updated value of the z-axis coordinate value is the z-axis coordinate value of the dot after change = 3-0 from the above equation. .5 (3-1) = 2. This calculation is performed for all dots constituting the object 603.

  Next, it is checked whether there is an object that does not have the object ID “001” other than the object 603 among the objects constituting the display video. Since the object 604 has not been processed yet, the object 604 is calculated for all the dots constituting the object 604.

  Since all the objects included in the display video are processed, the video signal processing unit 105 is based on the object data updated by the 3D conversion unit 109, and the objects 602, 603, and 604 are three-dimensional. Create video and display 3D video.

  By the above processing, the display image shown in FIG. 6 becomes as shown in FIG. In FIG. 10, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description of FIG.

  In FIG. 10, among the objects constituting the display video, the positions of the dots constituting the object 603 and the dots constituting the object 604 are changed and are newly displayed as objects 1003 and 1004.

  The coordinate values of the eight dots constituting the object 1003 are dot 1005 (7, 3, 2), dot 1006 (7, 3, 3), dot 1007 (10, 3, 2), dot 1008 (10, 3, 2). 3), dot 1009 (7, 5, 2), dot 1010 (7, 5, 3), dot 1011 (10, 5, 2), and dot 1012 (10, 5, 3).

  The coordinate values of the eight dots constituting the object 1004 are dot 1013 (12, 3, 5.5), dot 1014 (12, 3, 6), dot 1015 (15, 3, 5.5), dot 1016 ( 15, 3, 6), dot 1017 (12, 5, 5.5), dot 1018 (12, 5, 6), dot 1019 (15, 5, 5.5), dot 1020 (15, 5, 6) It has become.

  Therefore, the depth width of the object 1003 before the change is 2, whereas the magnification value is set to 0.5, so that the depth width of the object 1003 after the change is 3-2 = 1 is displayed.

  Similarly, the depth width of the object 604 before the change is 1, whereas the depth value of the object 1004 after the change is 6-5 by setting the magnification value to 0.5. .5 = 0.5 is displayed.

  The processing procedure of the 3D conversion unit 109 in the process from the display image of FIGS. 6 to 10 is shown in FIG. 5. For example, in the middle of the process from FIG. 6 to the display screen of FIG. Thus, it is conceivable that another object 1101 appears in the display image. At this time, the 3D conversion unit 109 reduces the depth width of the objects other than the selected object 602 in the display video by performing the processing shown in FIG.

  In the above example, the magnification value is set to 0.5 and the depth of the objects constituting the display video other than the selected object is displayed narrowly. For example, the magnification value is 1 or more. It is also possible to set so that the depth width of the selected object is set wider. At that time, after step S502 described above, as step S504, an object that matches the object ID of the selected object may be selected and the process of step S505 may be performed. In short, in order to make the selected object stand out and displayed, it is only necessary that the depth width of the selected object can be displayed relatively wider than the depth width of other objects.

  As described above, according to the first embodiment, it is possible to suppress a feeling of pressure peculiar to stereoscopic video for the viewer, and to make the display of the object specified by the viewer stand out.

(Second Embodiment)
In the second embodiment, by changing and displaying the depth position of a stereoscopically displayed object, the perspective difference of the depth position of the object on the entire display screen is eliminated, and a sense of pressure peculiar to stereoscopic video is suppressed. It is what is done.

Note that the receiving apparatus 101 of the second embodiment has the same configuration as that shown in FIG. 1, and the numbers given in FIG. 1 are used in the following description.

  Further, regarding the processing procedure performed by the receiving apparatus 101 of the second embodiment, the processing other than step S402 is performed in the same manner as in FIG.

  In the receiving apparatus 101 according to the second embodiment, a difference value is input in step S402. The difference value is a z-axis coordinate value that can be moved when the depth position of an object constituting the display video other than the object having the specified object ID is brought close to the depth position of the object having the specified object ID. .

  Further, the object display information change process performed by the 3D conversion unit 109 is performed in steps other than step S506 of FIG. 5 illustrated in the first embodiment, and therefore step S506 will be described in detail.

  In the second embodiment, in step S506, the size of the depth position of the object having the designated object ID is compared with the depth position of the objects constituting the video.

  If the depth position of the designated object is larger than the depth position of the object selected in step S504, the z-axis coordinate value of each dot constituting the object selected in step S504 is ( It is changed based on the z-axis coordinate value + difference value of each dot.

  If the depth position of the designated object is smaller than the depth position of the object selected in step S504, the z-axis coordinate value of each dot constituting the object selected in step S504 is ( It is changed based on the z-axis coordinate value-difference value of each dot.

  Next, an example in which the process of the second embodiment described above is applied to the display screen shown in FIG. The difference value is 2.

  In the 3D conversion unit 109, the dots constituting the object 603 and the object 604 are changed.

  For example, a description will be given taking the dot 617 constituting the object 603 as an example. The depth position of the object 602 is 7, and the z-axis coordinate value of the dot 617 is 1. Therefore, the depth position of the designated object is larger than the depth position of the object, and the z-axis coordinate value of each dot is changed based on (z-axis coordinate value + difference value of each dot). That is, the updated value of the z-axis coordinate value of the dot 617 is (1 + 2) = 3 from the above equation. This calculation is performed for all the dots constituting the object 603. Similarly, for the object 604 that does not have the object ID “001”, the calculation is performed for all the dots that form the object 604.

  By the above processing, the display image shown in FIG. 6 becomes as shown in FIG. In FIG. 12, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description of FIG.

  In FIG. 12, among the objects constituting the display video, the positions of the dots constituting the object 1203 and the dots constituting the object 1204 are changed.

The coordinate values of the eight dots constituting the object 1203 are the dots 1205 (7, 3,
3), dot 1206 (7, 3, 5), dot 1207 (10, 3, 3), dot 1208 (10, 3, 5), dot 1209 (7, 5, 3), dot 1210 (7, 5, 5), dot 1211 (10, 5, 3), and dot 1212 (10, 5, 5). At this time, the depth position is 5 and the depth width is 2.

  The coordinate values of the eight dots constituting the object 1204 are dot 1213 (12, 3, 7), dot 1214 (12, 3, 8), dot 1215 (15, 3, 7), dot 1216 (15, 3, 8), dot 1217 (12, 5, 7), dot 1218 (12, 5, 8), dot 1219 (15, 5, 7), and dot 1220 (15, 5, 8). At this time, the depth position is 8 and the depth width is 1.

  The objects 1203 and 1204 in FIG. 12 are displayed closer to the object 602 than the objects 603 and 604. Actually, the difference in the depth position of each object is reduced. Therefore, the perspective difference of the object of the whole screen is eliminated, the feeling of pressure peculiar to a three-dimensional image is suppressed, the burden on the viewer's eyes is alleviated, and the feeling of fatigue can be suppressed. In step S506 of the processing of the 3D conversion unit 109 in the second embodiment, the z-axis of each dot is used to change the depth width of the object by the magnification value and also change the depth position by the magnification value. The coordinate value may be changed based on (z-axis coordinate value × magnification value of each dot). According to this equation, the depth width of the object is changed by the magnification value, and the depth position is also changed by the magnification value.

  According to the above equation, the display image shown in FIG. 6 is as shown in FIG. In FIG. 13, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description of FIG.

  FIG. 13 shows an object 602, an object 1303 after the change processing is performed on the dots constituting the object 603, and an object 1304 after the change processing is performed on the dots constituting the object 604.

  The coordinate values of the eight dots constituting the object 1303 are dot 1305 (7, 3, 0.5), dot 1306 (7, 3, 1.5), dot 1307 (10, 3, 0.5), dot 1308 (10, 3, 1.5), dot 1309 (7, 5, 0.5), dot 1310 (7, 5, 1.5), dot 1311 (10, 5, 0.5), dot 1312 ( 10, 5, 1.5). At this time, the depth position is 1.5 and the depth width is 1.

  The coordinate values of the eight dots constituting the object 1304 are dot 1310 (12, 3, 2.5), dot 1314 (12, 3, 3), dot 1315 (15, 3, 2.5), dot 1316 ( 15, 3, 3), dot 1317 (12, 5, 2.5), dot 1318 (12, 5, 3), dot 1319 (15, 5, 2.5), dot 1320 (15, 5, 3) And changed. At this time, the depth position is 3, and the depth width is 0.5.

  The object 1303 and the object 1304 in FIG. 13 are displayed with the depth width narrowed by half compared to the objects 603 and 604. Further, the depth positions of the object 1303 and the object 1304 are close to a plane including the x coordinate axis, that is, a display for display.

  A viewer who sees an object close to the display can clearly see the object, and can reduce the depth width of the object 1303 and the object 1304 other than the object 602 while ensuring a clear image as a whole. it can.

As described above, when the z-axis coordinate value of each dot is changed based on (z-axis coordinate value × magnification value of each dot), for example, the object 1401 selected by the viewer as shown in FIG. The z-axis coordinate value may be a positive value, while the z-axis coordinate values of the objects 1402 and 1403 may be negative values.

  That is, by changing the depth width and depth position of the objects 1402 and 1403 as shown in FIG. 15, the depth positions of the objects 1502 and 1503 approach the depth position of the object 1401, and the perspective difference between each object Is resolved. For this reason, the feeling of pressure peculiar to stereoscopic images is suppressed and the burden on the viewer's eyes is reduced, and the selected object is displayed in an easy-to-see manner. In the second embodiment, the case where the magnification value is 1 or less has been described.

  As described above, according to the second embodiment, the depth of the object on the entire screen is reduced by narrowing the difference between the depth position of the object designated by the viewer and the depth position of the object constituting the display video other than the designated object. The difference in position is eliminated, and the pressure feeling peculiar to stereoscopic images can be suppressed.

  In addition, by displaying the depth position of the objects that make up the display video other than the object specified by the viewer close to a certain reference plane, the specified object stands out, while the entire screen is displayed. The perspective difference of the depth position of the object can be eliminated, and the pressure feeling peculiar to the stereoscopic image can be suppressed.

(Third embodiment)
In the first embodiment and the second embodiment, in order to select an object from the objects constituting the video and improve the visibility of the selected object, the depth width of objects other than the selected object The depth position was changed and displayed.

  In the third embodiment, a case will be described in which the display of a menu object for performing menu display is made easier to view by utilizing the first embodiment and the second embodiment.

  By the way, the menu object is composed of one or more item button objects for displaying menu items, as shown in FIG. In the third embodiment, the menu object 1601 includes an item A button object 1602, an item B button object 1603, an item C button object 1604, and an item D button object 1605.

  The object ID of the menu object 1601 is “900”, the object ID of the item A button object 1602 is “901”, the object ID of the item B button object 1603 is “902”, and the object ID of the item C button object 1604 is “903”. The description will be made assuming that the object ID of the item D button object 1605 is “904”.

  FIG. 17 shows a configuration of a receiving device 1701 that displays a menu. The receiving unit 102, the separation unit 103, the decoder 104, the video signal processing unit 105, the input unit 107, the control unit 1702, the storage units 1703, and 3D. A conversion unit 1704, a menu conversion unit 1705, and a display unit 110 are provided. In FIG. 17, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description of FIG.

  The input unit 107 receives a menu display request from a viewer. Further, an item button displayed on the menu can be selected by the input unit 107.

  When a menu display request is issued from the input unit 107, the control unit 1702 acquires the menu object 1601 and the item object of each item constituting the menu object 1601 from the storage unit 1703, and outputs them to the menu conversion unit 1705. Also, the object ID “900” of the menu object 1601 is output to the 3D conversion unit 1704.

  The menu conversion unit 1705 receives the object data of the menu object 1601 and the item button objects 1602, 1603, 1604, 1605 output from the control unit 1702. Then, predetermined processing is performed on the menu object 1601 and the item button objects 1602, 1603, 1604, and 1605, and the result is output to the video signal processing unit 105.

  Next, object data handled by the receiving device 1701 shown in FIG. 17 will be described.

  First, the object data of the menu object 1601 is composed of an object ID 1801, configuration object ID storage information 1802, and object display information 1803 as shown in FIG. The configuration object ID storage information 1802 stores the object ID of the item button object that configures the menu object 1801. For example, in the case of FIG. 16, the configuration object ID storage information 1802 includes the item A button object 1602, the item B button object 1603, the item C button object 1604, and the item D button object 1605 constituting the menu object 1601. The object IDs “901”, “902”, “903”, and “904” that are IDs are stored.

  Further, as shown in FIG. 19, the object data of the item button object includes an object ID 1901, link object ID storage information 1902, and object display information 1903. The link object ID storage information 1902 stores the object ID of the object to be displayed next when the item button object is selected.

  Next, a processing procedure performed by the receiving apparatus 1701 of the third embodiment will be described, and the flow is shown in FIG.

  First, the viewer requests display of the menu object 1601 from the input unit 107 (step S2001).

  Next, the control unit 1702 acquires the object data of the selected menu object 1601 from the storage unit 1703 (step S2002).

  Then, the object data of the item button objects 1602, 1603, 1604, and 1605 constituting the menu object 1601 is acquired from the storage unit 1703 from the configuration object ID storage information in the object data, and is output to the menu conversion unit 1705 (step S2003). .

  Further, the control unit 1702 obtains the maximum value among the depth positions of the objects constituting the display video when the display request of the menu object 1601 is requested from the 3D conversion unit 1704, and outputs the value to the menu conversion unit 1705. . (Step S2004).

Then, the depth positions of the menu object 1601 and the item button object are set so that the depth position of the menu object 1601 is larger than the maximum value based on the maximum value output from the control unit 1702 (step S2005). , The object data of all the item button objects 1602, 1603, 1604, 1605 constituting the menu object 1601 are output to the video signal processing unit 105.

  The video signal processing unit 105 creates a stereoscopic video based on the object data received from the 3D conversion unit 1704 and the menu conversion unit 1705 (step S2006).

  The display unit 110 displays the stereoscopic video created by the video signal processing unit 105 (step S2007).

  Note that the processing procedure shown in FIG. 20 does not describe processing for changing the depth width or depth position of the objects constituting the display video other than the menu object 1601, but the processing is, for example, first or second. The processing method described in the embodiment may be performed.

  Next, a third embodiment will be described based on the display image shown in FIG.

  FIG. 21 shows a display image displayed on the display screen 2101 before the menu is displayed. The display image is composed of a person object 2102 and a house object 2103. Furthermore, the position of each object according to the x-axis coordinate value and the z-axis coordinate value when the display image is viewed from above is shown.

  In order to display the menu, the viewer requests display of the menu object 1601 from the input unit 107.

  Next, the control unit 1702 acquires the object data of the menu object 1601 from the storage unit 1703.

  Then, the object ID of the item button object constituting the menu object 1601 is read from the configuration object ID storage information 1802 in the object data of the menu object 1601, and the item A button object 1602, the item B button object 1603, and the item C are read from the storage unit 1703. The object data of the button object 1604 and the item D button object 1605 are acquired, and the menu object 1601 and the acquired item button objects 1602, 1603, 1604, and 1605 are output to the menu conversion unit 1705.

  Further, the control unit 1702 acquires the value of the largest depth position among the objects constituting the display video from the 3D conversion unit 1704 and outputs the acquired value to the menu conversion unit 1705. In FIG. 21, since the person object 2102 is in front of the house object 2103, the control unit 1702 outputs the depth position of the person object 2102 to the menu conversion unit 1705.

  Note that the 3D conversion unit 1704 displays the object display information of each object data so that the depth width of the person object 2102 and the house object 2103 constituting the display video is reduced based on a magnification value predetermined by the viewer. To change. Since this processing has already been described in the first embodiment, a description thereof will be omitted.

The menu conversion unit 1705 performs processing such that the menu object 1601 and the item button object sent from the control unit 1702 are positioned in front of all the objects constituting the video, and then the video signal processing unit 105. Output to. That is, the depth position is set so that the person object 2102 is located behind the depth position of the menu object 1601 and the respective item button objects 1602, 1603, 1604, and 1605.

  The video signal processing unit 105 creates and displays a stereoscopic video of the menu object 1601, the person object 2102, and the house object 2103 based on the object data sent from the 3D conversion unit 1704 and the menu conversion unit 1705.

  By the above processing, the display image shown in FIG. 21 becomes as shown in FIG.

  According to FIG. 22, the person object 2201 and the house object 2202 are displayed with the depth width narrowed by the magnification value as compared to the person object 2102 and the house object 2103. In addition, the depth position of the menu object 2203 is displayed in front of the depth positions of other objects constituting the video. As a result, the menu object 2203 is displayed prominently compared to other objects, and the visibility of the menu is improved. In the example shown above, an arbitrary value may be set as long as the magnification value is 1 or less.

  By the way, an object may move to the front of the menu while the menu is displayed. For example, as shown in FIG. 23, the object 2302 located behind the menu object 2203 moves along the arrow 2303 and moves forward of the menu object 2203. As a result, a part of the displayed menu object 2203 is blocked by the object 2302, and the contents of the menu object 2203 cannot be correctly recognized.

  Therefore, even if the object 2302 moves in front of the menu object 2203, the 3D conversion unit 1704 performs the process shown in FIG. 24 so that the viewer can confirm the display of the menu object 2203.

  In the following description of the third embodiment, the depth position of the menu object 2203 refers to the depth position having the smallest value among the menu object 2203 and the item button object that configures the menu object 2203. And

  First, the value of the depth position of the menu object 2203 is acquired from the menu conversion unit 1705 via the control means (step S2401).

  Next, an object other than the menu object 2203 is selected from the objects constituting the video, and the depth position of the object is obtained (step S2402), and the depth position of the menu object 2203 and the menu object 2203 are displayed. The size of the object 2302 is compared with the depth position (step S2403).

  If there is an object 2302 having a depth position in front of the menu object 2203 (Y in step S2403), the depth position of the object 2302 is changed so as not to be in front of the menu object 2203 (step). S2404).

  Thereafter, it is checked whether or not the object IDs of all objects other than the menu object 2203 have been confirmed (step S2405).

If the object IDs of all objects displayed other than the menu object 2203 are confirmed (Y in step S2405), the process performed by the 3D conversion unit 1704 is terminated.

  If the object IDs of all objects displayed other than the menu object 2203 have not been confirmed (N in step S2405), the process returns to step S2402 and continues.

  FIG. 25 shows a display screen when the processing shown in FIG. 24 is performed. The 3D conversion unit 1704 takes a value smaller than the depth position of the menu object 2203 with respect to the object 2302 having a depth position larger than the depth position of the menu object 2203 among the objects constituting the display video. Change the depth position.

  Therefore, the display of the menu object 2203 is not blocked by changing the depth position of the object 2302 that is to be moved forward from the menu object 2203.

  Note that the control of the depth position of the object 2302 is not limited to the arrow indicating the movement of the object 2302 shown in FIG.

  If there is an object 2302 having a depth position that is larger than the depth position of the menu object 2203 in step S2404 of the processing procedure shown in FIG. 24, the depth position of the menu object 2203 is set larger than the depth position of the object. You may change so that.

  24, if there is an object 2302 having a depth position larger than the depth position of the menu object 2203 in step S2404 of the processing procedure shown in FIG. 24, the display color of the object 2302 is changed to semi-transparent in the video signal processing unit 105. You may do it. By changing to semi-transparent, the viewer can see the display of the menu even if the object 2302 moves to the front of the menu.

  As shown in FIG. 26, an object 2601 may newly appear before the menu object 2203. Even in such a case, by following the processing procedure shown in FIG. 24, the object 2601 that should appear newly in the foreground can be moved to the back side of the menu object 2203 and displayed as the object 2602.

  Note that the processing shown in FIG. 24 is applied not only to an object composed of a plurality of objects such as the menu object 2203 but also to an object composed of one object as described in the first embodiment, for example. It can be done.

  In FIG. 22, when the viewer selects an item button displayed on the menu from the input unit 107, the menu conversion unit 1705 further increases the depth width of the selected item button object. Easy-to-see menu display.

  Hereinafter, the processing procedure of the menu conversion unit 1705 will be described with reference to FIG. 27 together with FIG.

  First, the object ID of the item button object currently selected by the viewer is received from the input unit 107 (step S2701). For example, assume that the item A button object 1602 is selected in FIG.

  Next, the item A button object 1602 having the received object ID is searched from the menu conversion unit 1705 (step S2702).

  Next, the object display information is changed so that the depth width of the found item A button object 1602 is widened and the depth position comes to the front (step S2703).

  The changing method may be performed as in the first embodiment, for example. At that time, in order to widen the depth width so that the depth position comes to the front, for example, ((1−magnification value) × (minimum z-axis coordinate value of dots constituting the object) + (magnification value) It is desirable to change based on x (z-axis coordinate value of each dot). According to this equation, when the depth width of the object is changed, the depth position of the object is changed.

  Then, the changed object display information is output to the video signal processing unit 105 (step S2704).

  FIG. 28 shows a state in which the viewer selects the item A button object 1602 from the menu object 2203 after FIG. According to FIG. 28, it is possible to instantly know which button the viewer is currently selecting, and the operability is improved. Further, since the item A button object 1602 protrudes ahead of the menu object 2203, it appears to be displayed slightly larger than the other item button objects.

  In FIG. 28, the selected item A button object 2601 is displayed with emphasis over the other item button objects by widening the depth width, but the item B button object 1603 other than the selected item A button object 2601 is displayed. The item C button object 1604 and the item D button object 1605 may be displayed with a reduced depth.

  Further, the control unit 1702 may change the object data of the item A button object 2601 so that the depth position of the item A button object 2601 is further moved to the front. As a result, the item A button object 2601 is displayed on the front, and is displayed larger than the other item button objects, so that it is instantly known which button the viewer is currently selecting, and the operability is improved. .

  The control unit 1702 also sets the object data of the item button objects 1603, 1604, and 1605 so as to move the depth positions of the item B button object 1603, the item C button object 1604, and the item D button object 1605 to the far side. May be changed.

  By the way, when the viewer selects and determines the item A button object 1602 using the input unit 107, a new lower-level menu is displayed.

  In this way, when a lower layer menu is displayed for the upper layer, the depth of the menu object in the lower layer is set wider than the menu object 2203 in the upper layer, thereby making it easier for the viewer to see the menu. It can be performed.

In the following description of the third embodiment, the menu object having the object ID described in the link object ID storage information of the menu object is defined as a lower level menu object, and the lower level hierarchy is included in the link object ID storage information. A menu object having an object ID of a menu object is defined as a higher-level menu object with respect to a lower-level menu object.

  Therefore, the processing procedure of the menu conversion unit 1705 will be described, and the flow will be described with reference to FIG.

  First, the object ID of the item button object selected by the viewer is received from the input unit 107 (step S2901).

  Next, an item button object having an object ID of the item button object is searched for (step S2902).

  Next, the link object ID storage information of the found item button object is read (step S2903).

  Next, an object having the object ID specified in the link object ID storage information is acquired from the storage unit 1703 through the control unit 1702 (step S2904).

  Next, the object display information is changed so that the depth width of the object acquired from the control unit 1702 is increased (step S2905). Since the changing method has already been described in the first embodiment, the description thereof is omitted here.

  Then, the changed object display information is output to the video signal processing unit 105 (step S2906).

  Next, the processing procedure shown in FIG. 29 will be described based on the display image shown in FIG.

  First, the viewer selects and determines the item A button object 1602 from the input unit 107.

  Thereafter, the menu conversion unit 1705 searches for object data of the item A button object 1602.

  Next, the link object ID storage information of the item A button object 1602 is read, and the object ID of the lower-level menu object to be displayed next is acquired. In this case, it is assumed that information “910” is stored in the link object ID storage information.

  The menu conversion unit 1705 acquires object data for displaying an object having the object ID “910” as a new lower layer from the storage unit 1703 via the control unit 1702.

  Next, the depth width is changed in order to display the depth width of the menu object in the lower hierarchy wider than the upper hierarchy. In the present embodiment, it is assumed that the depth width of the menu object in the hierarchy one level lower than the upper hierarchy is changed to twice. Also, the depth width of the menu object in the lower layer relative to the upper layer may be set by the viewer inputting from a control device such as a remote controller, or may be set in advance by the viewer or the like.

  The changed object data of the lower-level menu object is output to the video signal processing unit 105 and displayed.

  As a result of the processing procedure shown in FIG. 29, the display image shown in FIG. 30 is obtained.

  In FIG. 30, a menu object 3001 which is a lower hierarchy is displayed with respect to a menu object 2203 which is an upper hierarchy.

  The video signal processing unit 105 creates a stereoscopic video based on the object data received from the 3D conversion unit 4412 (step S4703).

  The display unit 110 displays the stereoscopic video created by the video signal processing unit 105 (step S4704).

  In the sixth embodiment, when the object data including the operation code 4602 and the set value 4603 is received, the processing procedure shown in FIG. 47 is not necessarily performed. For example, depending on the setting on the receiving device side, even if object data including the operation code 4602 and the setting value 4603 is received, the operation code 4602 is forcibly rewritten to 0 and the processing shown in FIG. 47 is not performed. May be. Further, when a transmission signal is received without including the operation code 4602, the operation code 4602 may be handled as 0.

  In the above processing, the depth width of an object having object data that does not include an operation code or setting value other than the object data read in step S4706 or step S4709 is changed by the numerical value of the setting value, but step S4706 or Only the object data of the object having the object ID read in step S4709 may be changed.

  In that case, in step S4706 or step S4709, the object indicated by the object display information 4604 is read, and in step S4707 or step S4710, the depth width or depth position of the read object is changed by the set value 4603, and the video signal processing unit The data may be output to 105.

  Further, the object data to be transmitted is not limited to the above configuration, and may include only an object ID 4601 that specifies a specific object, only an operation code 4602, or only a setting value 4603. At this time, for example, a value preset in the receiving apparatus is used as the designated object, processing method, and set value.

  Further, an object already stored in the receiving apparatus can be specified by the object ID 4601 by object data including only the object ID 4601, the operation code 4602, and the setting value 4603.

  Note that a new operation code 4602 may be provided to change the depth position and depth width of the object so that the object can be specified to the receiving apparatus.

  When the set value is not included in the object data of the transmission signal, or when the receiving device cannot read, the processing can be performed based on the magnification value or the difference value set in advance by the receiving device.

  Even if the operation data and setting value are included in the object data of the transmission signal, whether or not to use the setting value on the receiving device side is arbitrary, and the viewer uses it for the receiving device. It can be set not to. Further, even if an operation code or a setting value included in the object data of the transmission signal is acquired, processing may be performed using a preset magnification value or difference value.

  In the first to fifth embodiments, an object is specified by the input unit 107. In the sixth embodiment, an object is specified by an object ID 4601. However, since the control unit 106 processes the object specified by the input unit 107 and the object specified by the object ID 4601 in the same manner, except for the difference in the method of specifying the object, the control unit 106 is first described in the fifth embodiment. The object processing method of the receiving apparatus described in the embodiment can be applied as it is.

  As described above, according to the sixth embodiment, a broadcasting system including a transmission device and a reception device that can change object data transmitted from the transmission device into information related to the depth direction of the object data. The visibility of the stereoscopically displayed video is improved, and the burden on the viewer's eyes is reduced.

  In addition, a transmission apparatus that can specify an object specified by a program producer or the like on the transmission apparatus side, and a reception apparatus that can change the information regarding the depth direction of the specified object or an object constituting a display video other than the specified object. With the broadcasting system composed of the above, the program producer can provide elaborate video effects to the viewer. In particular, it can be used when a program producer wants to display important information such as a TV news bulletin, and can display character information, thereby preventing the viewer from overlooking the display.

  Note that the receiving apparatuses shown in the first to sixth embodiments are not necessarily limited to the form in which video data is sent from the transmitting apparatus. For example, the present invention can be implemented even when displaying video data recorded on a storage medium such as a DVD.

  Note that, in the receiving apparatuses shown in the first to sixth embodiments, when object data is not included in the transmitted signal or only data for displaying a flat image is displayed. It may not be included. In that case, the control unit first determines whether the received image is displayed three-dimensionally or planarly in the receiving device.

When the viewer tries to select a specific object from the input unit, the input unit can obtain information on the object from the 3D conversion unit through the control unit. At this time, from the data acquired from the decoder, the control unit determines whether the display image is a three-dimensional display depending on whether a z-axis coordinate value can be acquired, for example, and whether or not a three-dimensional video signal has a flag indicating that it is stereoscopic video data. The flat display is determined, and if the received data is video data displayed in a flat manner, it can be displayed to the viewer that the object cannot be selected.

  However, even if the received data is video data displayed in a plane, the menu display, multi-screen list display, and broadcast program list display are displayed with reference to the object data stored in the storage unit. Therefore, a display request can always be made from the selection input unit.

  Then, regarding the menu display at that time, a three-dimensional display may be performed or a two-dimensional display may be performed.

  Moreover, even if the received data is video data displayed in a plane, the video may be displayed in a three-dimensional manner by processing the video data in the 3D conversion unit. In that case, as described in the first to fifth embodiments, for example, the menu may be displayed while suppressing the degree of stereoscopicization of the video.

  In the first to fifth embodiments, transmission data including object data is assumed. However, a plane image that is different for the left eye and the right eye from the transmission device is set as transmission data, so that a three-dimensional image can be obtained by the reception device. A method of reproducing the image is also conceivable.

  In this case, if the 3D conversion unit on the receiving device side processes the video other than the menu so as to reduce the degree of difference between the left-eye and right-eye flat images, the video other than the menu is displayed with a reduced depth. It is known that Therefore, the transmission data does not affect the present invention even if it includes object data or includes plane images that are different for the left and right eyes.

  Furthermore, the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

  The present invention relates to a transmission device that transmits video data and the like, a display device that can display video data in three dimensions, a transmission / reception system that can transmit and receive video data, a transmission / reception method, a display method, a transmission method, and video control.
