Description

  The present invention relates to an imaging apparatus capable of capturing and displaying two-dimensional and three-dimensional images.

  In recent years, portable devices with a photographing function such as a digital camera have overcome various poor photographing scenes by making full use of image processing. In recent years, there has been a 3D (three-dimensional) wave in the movie industry with a sense of realism, and the 3D display devices are also becoming popular following the television industry.

  In consumer photography equipment such as digital cameras, devices capable of 3D photography have been developed. There are a wide variety of proposals for methods of shooting and recording images including three-dimensional information and reproducing and observing them. For example, Patent Document 1 discloses a technique for creating an image having parallax by dividing incident light from a lens into a plurality of light beams and then entering the light into a plurality of imaging elements having different incident directivities. .

  There are various factors that enable humans to obtain a three-dimensional effect. In general, a three-dimensional effect is obtained based on information such as binocular parallax, motion parallax, binocular vergence, focus, and relative size. It is said that. In such information, methods for providing stereoscopic images artificially often use binocular parallax, which is the largest factor for obtaining a stereoscopic effect.

JP 2006-165601 A

  Thus, in order to enable stereoscopic viewing, it is necessary to capture an image for the right eye and an image for the left eye, that is, two images having parallax corresponding to the viewpoints of the left and right eyes. The right-eye image and the left-eye image are images that are shifted from each other according to the parallax. For this reason, a desired viewing angle is not always obtained unless the camera is photographed while confirming the 3D display.

  Further, due to various factors such as the distance between the right and left eye lenses and the distance to the subject, there is a difference between the stereoscopic effect perceived by the human eye and the stereoscopic effect obtained by photographing. Therefore, in order to perform shooting so as to obtain the stereoscopic effect desired by the photographer, it is necessary to perform shooting while confirming 3D display during camera shooting.

  However, the invention of Patent Document 1 is a technique that enables shooting and recording of 3D images, and cannot perform 3D display while shooting. In addition, there are devices that display recorded 3D images in 3D, but when shooting a subject in 3D, it is as easy as capturing a 2D image while confirming the 3D image to be shot by 3D display. Now, an imaging apparatus for taking pictures has not been developed.

  Moreover, conventionally, when viewing 3D display, it has been necessary to force the viewer to wear a glasses-type device in order to show the right-eye image and the left-eye image respectively to the right eye or the left eye. Further, in the image separation method in which the right eye image or the left eye image is selectively displayed using the lenticular lens or the like, the position of the viewer is limited and the resolution is lowered. In this type of display device, sufficient resolution cannot be obtained even during 2D display.

  In addition, a system has been developed that realizes autostereoscopic vision by changing the display direction of the left-eye image and right-eye image using a special liquid crystal panel and alternately displaying the left and right images in a time-division manner. Yes. In this method, the resolution is not sacrificed because the time-division display is performed. However, in this method, the frame rate is reduced to ½ compared to 2D display. Since a general human can recognize a display delay of 20 ms, there is a disadvantage that when the frame rate is halved, the real-time property is significantly impaired.

  In addition, an imaging apparatus that can easily switch between 3D imaging and 2D imaging with a single apparatus has not been developed due to the particularity of 3D imaging.

  When creating a 3D image, the rotation angle of the imaging system must be maintained so that the base line connecting the right-eye lens and the left-eye lens is horizontal, and the base line is rotated by 90 degrees. When shooting vertically, a 3D image cannot be obtained.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an imaging apparatus that can capture a 3D image while confirming a 3D image to be captured and can easily capture a 3D image and a 2D image. And

Furthermore, as the electronic finder, various types of finders such as a 2D display finder having only one display unit can be used. FIG. 1 shows an example of a finder for 3D display. In the electronic viewfinder for 3D display, as shown in FIG. 2, the display units 55R and 55L are provided so as to be spaced apart from each other, for example, corresponding to the distance between human eyes. The display units 55R and 55L can be configured by an organic EL or LCD.

  A finder information storage unit 53 is provided in the finder control unit 51 of the electronic finder circuit unit 50. The finder information storage unit 53 holds finder information related to the display device 55 of the electronic finder 13. The finder information indicates whether the display device 55 has one display unit or two display units.

  The communication unit 52 of the finder control unit 51 transmits and receives information to and from the communication unit 23 of the main body circuit unit 20 through a predetermined transmission path. When communication with the communication unit 23 of the main body circuit unit 20 is established, the finder control unit 51 can cause the communication unit 52 to transmit the finder information stored in the finder information storage unit 53 to the main body circuit unit 20. . Thereby, the main body circuit unit 20 can recognize that the display device 55 has the two display units 55R and 55L.

The optical image of the subject from the interchangeable lens 12 is formed on the imaging surface of the imaging device that constitutes the imaging unit 24. The imaging unit 24 is driven and controlled by the signal processing and control unit 21. The signal processing and control unit 21 has information on the imaging surface of the imaging element that constitutes the imaging unit 24. The signal processing and control unit 21 outputs a driving signal of the image sensor to the image capturing unit 24 based on the information on the imaging surface and the lens information, and captures an image signal obtained by photoelectric conversion of the optical image by the image sensor. The main body circuit unit 20 is provided with an audio recording unit 25, which collects sound outside the imaging apparatus 10 and outputs an audio signal to the signal processing and control unit 21.

Is set. For example, when the lens information indicates that the interchangeable lens has two lens portions, the left and right image signal generation unit 21a sets the imaging surface of the imaging unit 24 within the incident range of incident light from each lens unit. Accordingly, the image area is divided into a right-eye image area and a left-eye image area, and signal processing is performed using the image signal from each image area as a right-eye image signal or a left-eye image signal.

  Note that the left and right image signal generation unit 21a may set an image area according to processing such as aperture and zoom processing as well as information on the imaging surface and lens information.

  The main body circuit unit 20 is also provided with a clock unit 27 and an operation determination unit 28. The clock unit 27 generates time information used by the signal processing and control unit 21.

Further, the main body display unit 30 can be controlled by the signal processing and control unit 21 to display a menu display or the like for operating the imaging device 10.

  Furthermore, in the present embodiment, the main body circuit unit 20 is provided with a vertical / horizontal detection unit 29. The vertical / horizontal detection unit 29 can detect the orientation of the imaging apparatus main body 11, and outputs the vertical / horizontal detection information of the detection result to the signal processing and control unit 21.

  The signal processing and control unit 21 can control each unit in the main body circuit unit 20 and can control the interchangeable lens 12 and the electronic viewfinder 13 via the communication units 22 and 23. The signal processing and control unit 21 generates display control information based on the lens information from the interchangeable lens 12, the finder information from the electronic finder 13, and the vertical / horizontal detection information to perform optimal finder display.

  3 and 4 are explanatory diagrams for explaining the relationship between the interchangeable lens 12 and the electronic viewfinder 13 and the composition.

  FIG. 3A shows the imaging device 10, the interchangeable lens 12, and the electronic viewfinder 13 corresponding to FIGS. 1 and 2. An interchangeable lens 12 is attached to a lens mount (not shown) on the front surface of the imaging apparatus main body 11. The interchangeable lens 12 is for 3D photography having two imaging lens portions 12R and 12L. An accessory shoe 61 is provided at the upper end of the imaging apparatus main body 11. The electronic viewfinder 13 has an attachment portion 65 for detachably attaching to the accessory shoe 61. A holding portion 66 that holds the two display portions 55R and 55L is rotatably attached to the attachment portion 65.

  The accessory shoe 61 is provided with a contact portion 62 that constitutes the communication portion 23 of the main body circuit portion 20. By attaching the attachment portion 65 of the electronic finder 13 to the accessory shoe 61, the contact portion 62 is connected to the attachment portion 65. It is electrically connected to a provided contact portion (not shown). The contact part 62 of the attachment part 65 constitutes the communication part 52 of the electronic finder circuit part 50.

  The electronic finder 13 uses the communication unit 52 to determine which rotation position of the holding unit 66 is relative to the mounting unit 65, that is, which line connecting the display units 55 </ b> R and 55 </ b> L is to the imaging apparatus main body 11. Information indicating whether the angle is at such an angle can be transmitted to the main body circuit unit 20.

  FIG. 4A shows a state in which the user takes a picture while holding the imaging apparatus main body 11 horizontally in a state where the electronic finder 13 is attached to the accessory shoe 61. That is, FIG. 4A shows an example of horizontal composition shooting in which the imaging apparatus main body 11 is held horizontally. In this case, as shown in FIG. 3A, the base line connecting the imaging lenses 12R and 12L is horizontal and 3D imaging is possible. The user takes a picture with the eyes facing the eyepieces 67R and 67L provided on the display units 55R and 55L.

  In the example of FIGS. 3A and 4A, the vertical / horizontal detection unit 29 of the main body circuit unit 20 detects that the imaging device main body 11 is held horizontally. The signal processing and control unit 21 of the main body circuit unit 20 recognizes that the interchangeable lens 12 has two lens units 44R and 44L based on the lens information. The left and right image signal generation unit 21a sets the right-eye image region and the left-eye image region on the imaging surface of the imaging element of the imaging unit 24 based on the lens information.

  The left and right image signal generation unit 21a generates a right eye image and a left eye image based on signals read from each image region. These right-eye image and left-eye image are supplied to the finder control unit 51 of the electronic finder 13. The finder control unit 51 provides the right-eye image to the display unit 55R and the left-eye image to the display unit 55L. Thus, when the viewer looks into the eyepieces 67R and 67L of the electronic viewfinder 13, the 3D display based on the subject optical image captured by the imaging lenses 12R and 12L can be observed.

  FIG. 3B shows the imaging device 10, the electronic viewfinder 13, and the interchangeable lens 70 corresponding to FIGS. 1 and 2. The interchangeable lens 70 has one lens unit including the imaging lens 71. The interchangeable lens 70 is attached to a lens mount (not shown) on the front surface of the imaging apparatus main body 11.

  The interchangeable lens 70 has an interchangeable lens circuit unit similar to the interchangeable lens circuit unit 40 of FIG. 1, and can transmit lens information to the main body circuit unit 20. In addition, the interchangeable lens 70 is configured such that the main body circuit unit 20 controls the aperture, focus, zoom, and the like of the imaging lens 71.

  FIG. 3B shows a state in which the holding portion 66 is rotated 90 degrees from the state of FIG. 3A with respect to the attachment portion 65 so that the line connecting the display portions 55R and 55L is horizontal. ing.

  FIG. 4B shows a state in which the user takes a picture while holding the imaging apparatus main body 11 in the state of FIG. That is, FIG. 4B shows an example of vertical composition shooting with the imaging apparatus main body 11 held vertically. In this case, since 3D photography cannot be performed, an interchangeable lens 70 having only one imaging lens 71 is used as shown in FIG.

  Also in the vertical composition shooting, since the line connecting the eyepieces 67R and 67L provided in the respective display portions 55R and 55L is horizontal, the user takes an image with the eyes facing the eyepieces 67R and 67L while standing upright. It can be carried out.

  In the example of FIGS. 3B and 4B, the vertical / horizontal detection unit 29 of the main body circuit unit 20 detects that the imaging device main body 11 is held vertically. The signal processing and control unit 21 of the main body circuit unit 20 recognizes that the interchangeable lens 70 has one imaging lens 71 based on the lens information. The left and right image signal generation unit 21a sets one image area on the imaging surface of the imaging element of the imaging unit 24 based on the lens information, and generates an image signal from this area. This image signal is supplied to the finder control unit 51 of the electronic finder 13. The finder control unit 51 gives the image signal to the display units 55R and 55L. Thus, when the viewer looks into the eyepieces 67R and 67L of the electronic viewfinder 13, the 2D display based on the subject optical image captured by the imaging lens 71 can be observed with both eyes.

  Further, the signal processing and control unit 21 can give the 3D image and 2D image reproduced from the recording / reproducing unit 26 to the electronic viewfinder 13 to perform 3D display or 2D display.

  Note that the signal processing and control unit 21 can also display the image signal obtained by imaging on the main body display unit 30 for display. As shown in FIG. 4C, when shooting a moving image, for example, it is possible to take a picture while observing the taken image with the main body display unit 30 provided on the back surface of the main body 11 of the imaging apparatus.

(Optical system)
5 to 7 are explanatory views showing examples of the optical system employed in the interchangeable lens 12. 6 and 7 are disclosed in Japanese Patent Application Laid-Open Nos. 8-171151 and 2004-4869.

  FIG. 5 shows the positional relationship between the optical system and the imaging element when the imaging device 10 is viewed from above. FIG. 5 shows an example in which the interchangeable lens 12 employs a right-eye optical system 81R and a left-eye optical system 81L as optical systems that constitute the lens portions 44R and 44L, respectively. The imaging device main body 11 is provided with an imaging surface 82a of an imaging element 82 that constitutes the imaging unit 24 facing the optical systems 81R and 81L.

  A left-eye image region is set on the right side in the horizontal direction of the imaging surface 82a of the imaging element 82, and a right-eye image region is set on the left side in the horizontal direction of the imaging surface 82a. The light incident on the imaging lens 12R forms an image on the right-eye image region provided on the left side in the horizontal direction of the imaging surface 82a via the right-eye optical system 81R. The light that has entered the imaging lens 12L forms an image on the left-eye image region provided on the right side in the horizontal direction of the imaging surface 82a via the left-eye optical system 81L.

  6 and 7 show other examples of the optical system. 6 and 7 show the optical system when a horizontally long 3D image is captured. FIGS. 6A and 7A show the planar state, and FIGS. 7 (b) shows a state as seen from the lower surface of FIGS. 6 (a) and 7 (a). 6 and 7, the description will be made assuming that the image sensor 102 is employed as the image sensor of the image pickup unit 24 provided in the image pickup apparatus main body 11.

  In FIG. 6, the reflecting mirrors 104 and 105 are rotatably attached to a holder 106 fixed to the imaging device main body 11. The reflecting surfaces of the reflecting mirrors 104 and 105 can be rotated on the same plane. A fixed gap is provided between the reflecting mirror 104 and the reflecting mirror 105, and the tip of the partition wall 103 is inserted therein. Therefore, when the partition wall 103 is rotated, the reflecting mirrors 104 and 105 are rotated accordingly.

  The reflecting mirror 111 and the reflecting mirror 104, which are a pair of reflecting optical systems, are reflected from the reflecting surface of the reflecting mirror 111 after light from the subject (right subject image) is incident on the reflecting mirror 111, and then reflected. After being incident on the mirror 104, it is optically arranged sequentially from the incident side so that it is reflected by the reflecting surface of the reflecting mirror 104 and imaged on the upper imaging surface 102a. At this time, the reflecting surface of the reflecting mirror 104 and the reflecting surface of the reflecting mirror 111 are preferably substantially parallel to the extent that an image can be formed on the imaging surface 102a. Further, with respect to the reflecting mirror 112 and the reflecting mirror 105, which are another pair of reflecting optical systems, light from the subject (the subject image on the left side) receives the lower imaging surface 102a as in the case of the reflecting mirror 111 and the reflecting mirror 104. Are sequentially arranged optically from the incident side.

  The convex lens 109 is disposed between the reflecting mirror 111 and the reflecting mirror 104, and is used to form a subject image from the right side on the upper imaging surface 102a via the reflecting mirror 104. Accordingly, the convex lens 109 is disposed along the optical axis of the light emitted from the reflecting mirror 111. Similarly to the convex lens 109, the convex lens 110 is disposed between the reflecting mirror 112 and the reflecting mirror 105. Although a reflecting mirror is used in the reflecting optical system, a prism or other reflecting optical element may be used instead of the reflecting mirror. Further, although the convex lenses 109 and 110 are shown as single lenses, it goes without saying that they can be constituted by a plurality of lenses. Further, the reflecting mirror 111 and the convex lens 109 may be a prism having a convex surface that has the functions of the reflecting mirror 111 and the convex lens 109.

  Further, the interval S between the left and right optical axes 113 and 114 on the incident side shown in FIG. 6A is selected to be a predetermined value in consideration of the size and distance of the subject with reference to the human eye width. In order to form an object on the optical axes 113 and 114 at the center of the imaging surface 102a, the optical axes 115 and 116 passing through the convex lenses 109 and 110 are in a horizontal line H as shown in FIG. It is inclined with respect to the predetermined angle θ. This angle θ is calculated from the equation tan θ = a / S. In this way, by arranging the convex lenses 109 and 110 between the two reflecting mirrors 104 and 111 and 105 and 112, respectively, it becomes possible to project a subject having a wide angle of view in the horizontal direction on the imaging surface 102a. .

  In the optical system having such a configuration, the luminous flux of the subject image having parallax is incident on each of the reflection optical systems provided on the left and right, and is reflected by the two reflection surfaces in each of the reflection optical systems. The light beam exposes the upper half right-eye image region divided by the partition wall 103, and the other light beam exposes the lower half left-eye image region.

  A 3D image can be obtained by taking out signals from these right-eye image areas as right-eye image signals and taking out signals from the left-eye image area as left-eye image signals.

  In the above configuration, the reflecting mirrors 104 and 105 are rotated to obtain a 3D image of another size. That is, FIG. 7 shows a state where the reflecting mirrors 104 and 105 are rotated 90 degrees from the state of FIG. In this case, as a matter of course, the position of the convex lens is moved in conjunction with the rotation of the reflecting mirrors 111 and 112.

(Function)
Next, the operation of the embodiment configured as described above will be described with reference to FIGS. FIG. 8 is a flowchart showing camera control, and FIG. 9 is a flowchart showing a specific flow of finder display control in step S14 in FIG.

  In step S1 of FIG. 8, the signal processing and control unit 21 determines whether or not the shooting mode is set. Assume that the shooting mode is instructed. In this case, in step S2, the signal processing and control unit 21 performs autofocus control (AF), takes in a signal from the imaging unit 24, performs signal processing, and generates an image signal.

  When the shooting mode is instructed, the signal processing and control unit 21 determines whether or not the electronic viewfinder is connected in step S3.

  Now, it is assumed that the electronic finder is not connected to the accessory shoe 61 of the imaging apparatus main body 11. In this case, the signal processing and control unit 21 outputs the generated image signal to the main body display unit 8 to display the captured image (step S4).

  Next, the signal processing and control unit 21 determines whether or not an instruction to start shooting is instructed in step S5. If the start of shooting is not instructed, the signal processing and control unit 21 determines whether or not a power-off operation has been performed in step S18. If the power-off operation has not been performed, the processing is performed in step S1. Return to. If a power off operation is performed, the power is turned off in step S19.

  If it is determined in step S5 that the user has instructed to start shooting, the signal processing and control unit 21 performs moving image shooting (step S6). In FIG. 8, in the display mode on the main body display unit 30, it has been described that moving image shooting is performed by an instruction to start shooting, but still image shooting may be performed.

  When an instruction to end shooting is given, the signal processing and control unit 21 shifts the processing from step S7 to step S8 to create an image file. That is, the signal processing and control unit 21 encodes the generated image signal at the same time as shooting and transfers the image information from the recording / playback unit 26 to the recording medium. The image information transferred to H.26 is converted into a file.

  Next, in step S1, it is determined that the reproduction mode has been instructed. In this case, the signal processing and control unit 21 shifts the processing from step S9 to step S10, reads the information of the list of files recorded in the recording / reproducing unit 26, and displays the file list display on the main body display unit 30. Display.

  When the user selects a file at the time of displaying the file list (step S11), the signal processing and control unit 21 reads out the selected file via the recording / playback unit 26, performs a decoding process, and performs an image signal and Play an audio signal. The signal processing and control unit 21 gives the reproduced image signal and audio signal to the main body display unit 30 for display (step S12).

  If an end operation is performed when the file list is displayed, the signal processing and control unit 21 moves the process from step S11 to step S13 and ends the reproduction mode.

  In the present embodiment, display of the captured image is controlled based on the finder information from the electronic finder, the lens information from the interchangeable lens, and the vertical and horizontal detection information from the vertical and horizontal detection unit 29.

  That is, in step S3, when the signal processing and control unit 21 determines that the electronic finder is connected, the process proceeds to step S14 to perform finder display control.

  In the finder display control, in step S21 of FIG. 9, the signal processing and control unit 21 determines whether or not the connected electronic finder is for 3D. Now, it is assumed that the electronic finder 13 is connected to the accessory shoe 61 of the imaging apparatus main body 11. The signal processing and control unit 21 captures finder information via the communication unit 52 of the electronic finder 13 and the communication unit 23 of the main body circuit unit 20. Based on this finder information, the signal processing and control unit 21 recognizes that the electronic finder 13 has two display units 55R and 55L.

  Next, in step S22, the signal processing and control unit 21 determines whether or not the interchangeable lens is a 3D interchangeable lens. Now, it is assumed that the interchangeable lens 12 is connected to the lens mount of the imaging apparatus main body 11. The signal processing and control unit 21 captures lens information via the communication unit 42 of the interchangeable lens 12 and the communication unit 22 of the main body circuit unit 20. Based on this lens information, the signal processing and control unit 21 recognizes that the interchangeable lens 12 includes lens units 44R and 44L including two imaging lenses 12R and 12L, respectively.

  In this case, the signal processing and control unit 21 reads the right-eye and left-eye image signals in step S23. That is, the left and right image signal generation unit 21a of the signal processing and control unit 21 sets the right-eye image region and the left-eye image region according to the incident light from the lens units 44R and 44L based on the lens information. The left and right image signal generation unit 21a reads the right eye image signal and the left eye image signal from each image region.

  Next, in step S <b> 24, the signal processing and control unit 21 performs right eye image and left eye image enlargement / reduction processing and frame image generation processing. The image sizes of the right-eye image and the left-eye image depend on the size of the imaging surface of the imaging device of the imaging unit 24 and the incident range by the optical system. For this reason, the image sizes of the right-eye and left-eye images may be different from the image sizes of the display units 55R and 55L of the electronic viewfinder 13. Therefore, the signal processing and control unit 21 performs an enlargement / reduction process according to the image sizes of the right-eye image and the left-eye image in accordance with the image sizes of the display units 55R and 55L. Also, frame images corresponding to the aspect ratios of the right-eye and left-eye images and the display image are generated and superimposed on the enlarged and reduced right-eye and left-eye images.

  The signal processing and control unit 21 provides the generated right-eye and left-eye image signals to the finder control unit 51 of the electronic finder 13 via the communication units 23 and 52. The finder control unit 51 controls the display driving unit 54 to provide the right eye image signal to the display unit 55R and the left eye image signal to the display unit 55L (step S25), and returns the processing to the main routine. Thus, 3D display based on the subject optical image captured through the optical lens 12 is performed on the display device 55 of the electronic viewfinder 13.

  10 and 11 are explanatory diagrams for specifically explaining the processing of steps S23 to S25. 10 and 11 illustrate an example in which a horizontally long captured image is obtained by the imaging surface 90 of the image sensor of the imaging unit 24, and an example in which a vertically long captured image is obtained.

  A right-eye image area 91R and a left-eye image area 91L are set on the imaging surface 90 in FIG. These image regions 91R and 91L are obtained, for example, by adopting the optical system shown in FIG. 6 as the lens portion of the interchangeable lens.

  A right-eye image region 95R and a left-eye image region 95L are set on the imaging surface 90 in FIG. These image regions 95R and 95L are obtained, for example, by adopting the optical system shown in FIG. 7 as the lens portion of the interchangeable lens.

  As is clear from the comparison between FIG. 10A and FIG. 11A, the image areas 91R and 91L in FIG. 10A are horizontally longer than the image areas 95R and 95L in FIG. . In this way, a horizontally long captured image is obtained from the imaging surface 90 in FIG. 10A, and a vertically long captured image is obtained from the imaging surface 90 in FIG.

  For example, when the optical system shown in FIG. 6 is employed, the signal processing and control unit 21 sets the right-eye and left-eye image regions 91R and 91L shown in FIG. 10A in step S23. become.

  For example, when the optical system shown in FIG. 7 is adopted, the signal processing and control unit 21 sets the right-eye and left-eye image regions 95R and 95L shown in FIG. 11A in step S23. Do.

  FIG. 10B shows an example in which the image for the right eye and the image for the left eye read from the image areas 91R and 91L are displayed on the display units 55R and 55L of the electronic viewfinder. In the display area 92R of the display section 55R, a right-eye image display area 93R is provided at the center, and a frame image area 94R is provided at the top and bottom. The right-eye image read from the image area 91R is displayed in the right-eye image display area 93R of the display area 92R of the display unit 55R.

  Similarly, in the display area 92L of the display section 55L, a left-eye image display area 93L is provided at the center, and a frame image area 94L is provided at the top and bottom. The left-eye image read from the image area 91L is displayed in the left-eye image display area 93L of the display area 92L of the display unit 55L.

  FIG. 11B shows an example in which the image for the right eye and the image for the left eye read from the image areas 95R and 95L are displayed on the display units 55R and 55L of the electronic viewfinder.

  If the entire image read from the image areas 95R and 95L is enlarged and reduced and displayed on the display areas 92R and 92L of the display portions 55R and 55L, a relatively wide frame image is displayed on the left and right of the display areas 92R and 92L. The right-eye and left-eye images are displayed in a relatively narrow area at the center of the display areas 92R and 92L.

  Therefore, in consideration of the visibility of the image, the sense of presence, etc., as shown in FIG. 11B, only the part of the center in the vertical direction of the image read from the image regions 95R and 95L is displayed in the display regions 92R and 92L. A display method for displaying the entire area is adopted.

  That is, the signal processing and control unit 21 causes the display units 55R and 55L to display the image 95R ′ obtained by enlarging the image read from the image regions 95R and 95L and the image portion at the center in the vertical direction of the image 95L ′.

  This gives priority to spreading in the left-right direction when viewed with the left and right eyes, and makes it easy to view. Further, even if it is considered that the photograph taken is displayed on a wide-screen TV or the like, such finder display confirmation is actually more appropriate.

  Here, it is assumed that the user instructs to capture a still image while observing the 3D display. Then, the signal processing and control unit 21 shifts the processing from step S15 of FIG. 8 to step S17 and performs still image shooting. That is, the signal processing and control unit 21 compresses the still images of the right-eye and left-eye images at the shooting instruction timing, and causes the recording / reproducing unit 26 to record them on the recording medium (step S8). Further, the signal processing and control unit 21 displays the still images of the right-eye image and the left-eye image on the display units 55R and 55L for a predetermined time.

  Further, it is assumed that the user gives an instruction to shoot a moving image while observing the 3D display. In this case, the signal processing and control unit 21 moves from step S15, S16 to step S6 to perform moving image shooting.

  In this way, 3D still images and moving images can be captured while confirming the 3D display during shooting.

  Furthermore, in this embodiment, an interchangeable lens for 2D photography can be used. Assume that an interchangeable lens 70 shown in FIG. 3B is attached as an interchangeable lens. In this case, the signal processing and control unit 21 determines whether or not the process is shifted from step S22 to step S26 to perform vertical composition shooting.

  That is, the signal processing and control unit 21 determines whether the posture of the imaging apparatus main body 11 is horizontal or vertical based on the vertical / horizontal detection information from the vertical / horizontal detection unit 29. Now, it is assumed that the posture of the imaging apparatus main body 11 is horizontal (horizontal composition shooting state). In this case, the signal processing and control unit 21 outputs the image signal obtained by imaging to the finder control unit 51 as it is. The display drive unit 54 of the finder control unit 51 provides an image signal to the two display units 55R and 55L based on the signal processing and display control information from the control unit 21. As a result, the same image based on the subject optical image captured via the imaging lens 71 is displayed on the display units 55R and 55L (step S29).

  Here, it is assumed that the posture of the imaging apparatus main body 11 is vertical as shown in FIG. In this case, the electronic finder 13 is assumed to have a horizontal line connecting the display units 55R and 55L.

  In this case, in step S27, the signal processing and control unit 21 determines whether the rotation angle of the posture of the imaging apparatus main body 11 is 90 degrees or 270 degrees based on the vertical / horizontal detection information. Then, the signal processing and control unit 21 rotates the image obtained by imaging by 90 degrees or 270 degrees based on the vertical / horizontal detection information, and displays the image on the top and bottom of the captured image and the display units 55R and 55L of the electronic viewfinder 13. The top and bottom of the image to be matched are matched.

  Next, in step S28, the signal processing and control unit 21 performs enlargement / reduction processing of the right-eye image and left-eye image, and frame image generation processing. Thus, the size and aspect ratio of the captured image are matched with the size and aspect ratio of the display image. Thus, the captured image including the frame image is supplied to and displayed on the display units 55R and 55L in step S29.

  Furthermore, in this embodiment, an electronic viewfinder for 2D display can be used. Assume that an electronic viewfinder for 2D display is attached as an electronic viewfinder. In this case, the signal processing and control unit 21 proceeds from step S21 to step S30 to determine whether or not the interchangeable lens is for 3D shooting.

  When the interchangeable lens is for 2D shooting, that is, when the interchangeable lens and the electronic viewfinder are for 2D, the signal processing and control unit 21 outputs the image signal based on the captured image as it is in 2D electronic in step S31. Give it to the display part of the viewfinder and display it. Thereby, the captured two-dimensional image is displayed by the electronic viewfinder.

  When the interchangeable lens is for 3D shooting, that is, when the right-eye and left-eye images are captured by the imaging unit 24, the signal processing and control unit 21 displays the left-eye image signal on the display unit 55R in step S32. , 55L for display. As a result, the left-eye image is displayed on both the display units 55R and 55L. In step S32, it is obvious that the right-eye image signal may be given to the display units 55R and 55L. In step S32, the user may perform vertical composition shooting. In this case, the signal processing and control unit 21 rotates the left-eye image by 90 degrees so that the left-eye image and the display image coincide with each other on the basis of the vertical / horizontal detection information and displays the left-eye image on the display units 55R and 55L. You may make it display.

  FIG. 12 is an explanatory diagram for explaining the processing in step S31. FIG. 12A shows an example in which an imaging element having a vertically long imaging surface 96 is adopted as the imaging unit 24. The image obtained by the imaging surface 96 in FIG. 12A is enlarged and reduced, and then displayed as an image 97 in the display areas 92R and 92L of the display units 55R and 55L, as shown in FIG. 12B. The

  Thus, in this embodiment, 3D still images and moving images can be captured while confirming 3D display at the time of shooting. Further, in the present embodiment, 3D shooting and 2D shooting are possible, and switching is very easy. Furthermore, even if the electronic viewfinder is for 3D or 2D, display suitable for it is possible. That is, regardless of whether the interchangeable lens is for 3D or 2D, and the electronic viewfinder is for 3D or 2D, appropriate display is possible depending on the combination thereof.

  Moreover, in the invention of Patent Document 1 described above, a 3D image is generated by using two sets of imaging units, and images obtained between the two sets of imaging elements need to be synchronized in time. Stereo vision cannot be performed well on left and right images that are not synchronized. Particularly when a moving object is photographed, left and right images that are shifted in time series are likely to be generated.

  On the other hand, in this embodiment, this problem can be solved at low cost by using a single imaging unit.

(Second Embodiment)
FIG. 13 is a flowchart showing the second embodiment of the present invention. In FIG. 13, the same procedures as those in FIG. The hardware configuration of this embodiment is the same as that of the first embodiment shown in FIGS. This embodiment differs from the first embodiment only in that display control is performed according to the type of interchangeable lens.

  In 3D imaging in the first embodiment, two image areas are set on the imaging surface of one imaging element, and a right-eye image and a left-eye image are obtained from each area. In this case, when the optical system shown in FIG. 6 is adopted as the lens portion of the interchangeable lens, a horizontally long image is obtained, and when the optical system shown in FIG. 7 is adopted, a vertically long image is obtained. When considering the effective use of the imaging surface of the imaging device, it is better to use the optical system shown in FIG. Even in this case, when a general 2D image sensor is employed, the obtained right-eye image and left-eye image are horizontally long images.

  Compared to these right-eye and left-eye images, the display area of the display unit of the electronic viewfinder is slightly longer. Therefore, when setting the right-eye and left-eye image regions above and below the image pickup surface of the image pickup device, it is preferable to set the optical system of the lens unit appropriately and to arrange the image pickup surface of the image pickup device vertically. Can be used effectively.

  Therefore, in the present embodiment, the interchangeable lens is switched and the finder display control is performed based on whether the imaging element is arranged in the horizontal direction (longitudinal) or in the vertical direction (longitudinal). It is like that. FIG. 14 is an explanatory diagram for explaining an interchangeable lens employed in the present embodiment.

  FIG. 14A shows a state in which the interchangeable lens 121 is attached to a lens mount (not shown) of the imaging apparatus main body 11. The interchangeable lens 121 is attached to the attachment portion 122 so as to be rotatable about the optical axis. The interchangeable lens 121 includes imaging lenses 121R and 121L that can capture a right-eye image and a left-eye image. By rotating the interchangeable lens 121 with respect to the imaging apparatus main body 11, imaging is performed in both cases where the imaging apparatus main body 11 is positioned at the rotation position for horizontal composition shooting and at the rotation position for vertical composition shooting. The base line connecting the lenses 121R and 121L can be kept horizontal.

  FIG. 14B shows a state in which the interchangeable lens 123 is attached to a lens mount (not shown) of the imaging apparatus main body 11. The interchangeable lens 123 is attached to the attachment portion 122 so as to be rotatable about the optical axis. The interchangeable lens 123 has imaging lenses 123R and 123L that can capture a right-eye image and a left-eye image. By rotating the interchangeable lens 123 with respect to the imaging device main body 11, imaging is performed in both cases where the imaging device main body 11 is positioned at the rotation position for horizontal composition shooting and at the rotation position for vertical composition shooting. The base line connecting the lenses 123R and 123L can be kept horizontal.

  In the present embodiment, the interchangeable lens 123 can form a subject image in a wider area on the imaging surface of the image sensor than the interchangeable lens 121.

  If it is determined in steps S21 and S22 in FIG. 13 that the electronic viewfinder and the interchangeable lens are for 3D, the signal processing and control unit 21 determines whether the image sensor is arranged horizontally in the next step S41. Determine whether or not.

  Assume that the imaging surface of the imaging device is arranged horizontally when the imaging apparatus main body 11 is in the state of the horizontal composition shooting shown in FIG. In this case, when the imaging apparatus main body 11 is in the state of vertical composition shooting, the imaging surface of the imaging device is arranged vertically long. Even in the state of vertical composition shooting, 3D shooting is possible by keeping the baseline connecting the imaging lenses 121R and 121L and the imaging lenses 123R and 123L horizontal.

  The signal processing and control unit 21 sets an image area for horizontal composition shooting in step S42 when it is in the horizontal composition shooting state, and step S43 when it is in the vertical composition shooting state. In, an image area for vertical composition is set.

  FIG. 15 is an explanatory diagram for explaining right-eye and left-eye image regions set on the imaging surface of the imaging element. FIG. 15A shows an image area at the time of horizontal composition shooting, and FIG. 15B shows an image area at the time of vertical composition shooting.

  FIG. 15A shows the imaging surface 125 of the image sensor at the time of horizontal composition shooting. On the imaging surface 125, the signal processing and control unit 21 sets a right-eye image region 126R and a left-eye image region 126L.

  In FIG. 15A, since the right-eye and left-eye image regions 126R and 126L are arranged above and below the imaging surface 125, the image is inevitably narrow in the vertical direction. For this reason, when 3D shooting of a high subject, it is not possible to cover a sufficient shooting range.

  Therefore, when it is desired to secure a sufficient shooting range in the vertical direction, vertical composition shooting is employed. That is, in this case, using the interchangeable lens 123, the imaging apparatus main body 11 is set in a state of vertical composition shooting while maintaining the base line connecting the imaging lenses 123R and 123L horizontal. Thereby, the imaging surface 125 of the imaging device becomes a vertically long imaging surface 125 ′.

  In this case, a right-eye image region 127R and a left-eye image region 127L are set on the imaging surface 125 '. In the image area 127R for the right eye and the image area 127L for the left eye, since the imaging range by the interchangeable lens 123 is wide, it is not possible to obtain all of the captured images indicated by the broken lines. However, although the image portions at both ends in the left-right direction are sacrificed, an image with an aspect ratio suitable for 3D depiction of a building or the like can be obtained.

  In step S44, the signal processing and control unit 21 performs enlargement / reduction processing. Thus, the right eye image and the left eye image after the enlargement / reduction processing are displayed on the display units 55R and 55L of the electronic viewfinder 13 (step S25).

  On the other hand, if it is determined in steps S21 and S30 in FIG. 13 that the electronic viewfinder is for 2D display and the interchangeable lens is for 3D, the signal processing and control unit 21 determines that the image sensor is in the next step S46. It is determined whether or not it is arranged horizontally. The signal processing and control unit 21 sets an image area for horizontal composition shooting in step S47 when the state is in horizontal composition shooting, and step S48 when in the state of vertical composition shooting. In, an image area for vertical composition is set.

  Next, the signal processing and control unit 21 creates an intermediate image in step S49. For example, the signal processing and control unit 21 estimates the corresponding points of the right-eye image and the left-eye image, and generates an image for supplementing the middle of these images. Then, in step S50, the signal processing and control unit 21 displays the intermediate image on the display units 55R and 55L.

  Note that the processing when it is determined in steps S22 and S30 that the interchangeable lens is for 2D is the same as that in FIG. In this case, an image captured by the 2D imaging lens 71 (see FIG. 3B) may be displayed on the left and right display units 55R and 55L.

  As described above, the present embodiment can provide the same effects as those of the first embodiment, and performs setting, enlargement, and reduction processing of an image area according to the longitudinal direction of the image sensor and the type of the interchangeable lens. It is possible. In addition, when a 3D image is displayed in 2D, it is possible to display using the characteristics of the 3D image.

  In the present embodiment, an example is described in which an imaging element whose imaging surface is horizontally long at the time of horizontal composition shooting is described. However, an imaging element having an imaging surface that is vertically long at the time of horizontal composition shooting may be employed. In this case, it is obvious that 3D imaging using the imaging element can be effectively performed without rotating the imaging apparatus main body by 90 degrees.

(Third embodiment)
FIGS. 16 to 18 relate to the third embodiment of the present invention, FIG. 16 is an explanatory diagram for explaining the connection between the interchangeable lens 12 and the electronic component 130, and FIG. 17 is a diagram for explaining the usage method. FIG. 18 is a flowchart showing an operation flow. In FIG. 16, the same components as those in FIG.

  The hardware configuration of this embodiment is the same as that of the first embodiment shown in FIGS. This embodiment is different from the first embodiment only in that an electronic component 130 is attached and used instead of the electronic viewfinder 13.

  The electronic component 130 includes a mounting portion 131, a signal cable 132, and electronic glasses 133. The attachment portion 131 is detachably attached to the accessory shoe 61 at the upper end of the imaging device main body 11. By attaching the attachment portion 131 to the accessory shoe 61, the contact portion 62 is electrically connected to a contact portion (not shown) provided on the attachment portion 131. Accordingly, the communication unit 23 of the main body circuit unit 20 (see FIG. 1) can transmit and receive signals to and from the electronic glasses 133 via the signal cable 132.

  The electronic glasses 133 have electronic shutters 133R and 133L at positions corresponding to the left and right eyes. The electronic shutters 133R and 133L can be controlled by the signal processing and control unit 21 to limit the amount of light entering the eyes independently of each other.

  In the present embodiment, the signal processing and control unit 21 supplies the right-eye image signal and the left-eye image signal to the main body display unit 30 alternately in a time division manner. Accordingly, the right-eye image and the left-eye image are alternately displayed on the main body display unit 30 in a time division manner.

  The signal processing and control unit 21 controls the electronic shutters 133R and 133L of the electronic glasses 133 in synchronization with the display of the main body display unit 30. That is, the signal processing and control unit 21 blocks the incident light of the electronic shutter 133L at the timing when the right-eye image is displayed on the main body display unit 30, and the electronic signal is displayed at the timing when the left-eye image is displayed on the main body display unit 30. The incident light from the shutter 133R is blocked.

  FIG. 17 shows a state in which a person wears the electronic glasses 133 and confirms the display on the main body display unit 30. A person sees a 3D display on the main body display unit 30 provided with a display area, for example, on the back of the imaging apparatus main body 11 with the electronic glasses 133 being worn.

  Next, the operation of the embodiment thus configured will be described with reference to FIG. FIG. 18 shows display processing corresponding to FIG.

  The signal processing and control unit 21 causes the main body display unit 20 to display the left-eye image and the right-eye image in a time-sharing manner. In this case, the signal processing and control unit 21 uses the time information from the clock unit 27 to switch and display each image at a predetermined display time.

  Assume that the left-eye image is being displayed. The signal processing and control unit 21 uses the clock information to start counting up the left-eye display counter from the start of displaying the left-eye image. In step S61 in FIG. 18, the signal processing and control unit 21 determines whether or not a predetermined display time has elapsed from the display of the left-eye image, based on the count value of the left-eye display counter. If it has not elapsed, the signal processing and control unit 21 continues to shield the electronic shutter 133R on the right eye side (step S62) and restricts the light incident on the right eye. Then, in step S63, the signal processing and control unit 21 supplies the left-eye image signal to the main body display unit 30, continues the display of the left-eye image, and returns the processing to the main routine of FIG.

If it is determined by the count value of the left-eye counter that a predetermined display time has elapsed since the display of the left-eye image, the signal processing and control unit 21 proceeds from step S61 to step S67 and resets the right-eye display counter. The process proceeds to step S64. In step S64, the signal processing and control unit 21 determines whether the right-eye image has been displayed for a predetermined time based on the count value of the right-eye display counter. In the next step S65, the signal processing and control unit 21 blocks the electronic shutter 133L on the left eye side. Limiting the light incident on the left eye. Next, in step S66, the signal processing and control unit 21 gives the right-eye image signal to the main body display unit 30, displays the right-eye image, and returns the processing to the main routine of FIG. 9. Signal processing and control unit 21 If it is determined from the count value of the right-eye counter that a predetermined display time has elapsed since the display of the right-eye image, the process proceeds from step S64 to step S68 to reset the left-eye display counter and then return to the main routine.

  When the process proceeds from the main routine to step S61, the signal processing and control unit 21 determines whether the left-eye image has been displayed for a predetermined time based on the count value of the left-eye display counter.

  Thereafter, the same operation is repeated to limit the incident light of the left eye by the electronic shutter 133L, and simultaneously display the right eye image on the main body display unit 30 for a predetermined period, and then limit the incident light of the right eye by the electronic shutter 133R. At the same time, the left-eye image is displayed on the main body display unit 30 for a predetermined period. Thereby, 3D display using the main body display unit 30 is enabled.

  Thus, in the present embodiment, 3D display is possible by the main body display unit 30 having only one display unit.
