Further, the graphic drawing unit 1312 does not draw a graphic corresponding to the locus of the touch operation when a touch operation is performed on a toolbar image or a setting image described later or when the drawing mode is not set. The background image is usually a white solid image, but may be other images, for example, an image based on image data selected by the user.

  The object operation unit 137 determines the graphic drawn on the screen 11a by the graphic drawing unit 1312 as one object based on one or more touch operations. More specifically, when a plurality of touch operations are performed, the object operation unit 137 sets the interval between the touch operations to a predetermined time (for example, 1) based on the time information stored in the touch operation information management unit 1311. Each touch operation is recognized as one object creation operation. For example, when six touch operations A, B, C, D, E, and F are performed in this order, the time interval between the touch operation A and the touch operation B is equal to or longer than the predetermined time. Yes, the time interval between the touch operation B and the touch operation C is less than the predetermined time, the time interval between the touch operation C and the touch operation D is less than the predetermined time, and the touch operation D and the touch operation When the time interval between the touch operation E and the touch operation F is less than the predetermined time, the object operation unit 137 includes an object including only the touch operation A. There are three operations, namely, an object creation operation β including three touch operations of touch operations B to D, and an object creation operation γ including two touch operations of touch operations E and F. It recognizes that the object creation operation has been performed.

  Then, the object operation unit 137 determines the graphic drawn on the screen 11a by the graphic drawing unit 1312 as one object based on the touch operation included in the object creation operation. For example, the object operation unit 137 determines one figure drawn based on the touch operation A included in the object creation operation α as one object. In addition, the object operation unit 137 determines the three graphics drawn based on the touch operations B to D included in another object creation operation β as another one object. In addition, the object operation unit 137 determines two figures drawn based on the touch operations E and F included in another object creation operation γ as still another object.

  Furthermore, the object operation unit 137 enables an edit operation on each object in the object edit mode. More specifically, the object operation unit 137 edits an object based on position information and time information stored in the touch operation information management unit 1311 when a touch operation is performed in the object editing mode. . For example, when the start position of the touch operation is an area displaying the object and the end position is another area, the object is moved to the other area by the object operation unit 137. Further, for example, when the touch operation is two touch operations in a predetermined short time with respect to the area where the object is displayed, so-called double click, the object operation unit 137 enlarges the object.

  The all display setting storage unit 132 stores a plurality of display setting information, and the display setting storage unit 133 stores any one of the plurality of display setting information. The display setting information stored in the display setting storage unit 133 is information that predetermines one correspondence relationship between the touch operation and the graphic displayed on the screen 11a of the display unit 11 before the touch operation is performed. . That is, when a touch operation is performed on the work area in the drawing mode, the graphic drawing unit 1312 is displayed according to the display setting information stored in the display setting storage unit 133 at the time when the position information is acquired for the touch operation. Draws a figure corresponding to the touch operation.

The blue pen setting information is information for setting a figure drawn by the figure drawing unit 1312 to a figure that directly represents the locus of the touch operation with a blue line having a predetermined thickness.

  The eraser setting information is information for setting the figure drawn by the figure drawing unit 1312 to a figure that directly represents the locus of the touch operation with a line of a predetermined thickness, and the color of each part of the line This is information set to the same color as the color of the background image at each location. The thick pen setting information is information for setting the figure drawn by the figure drawing unit 1312 to a figure that directly represents the locus of the touch operation with a black line thicker than the line in the black pen setting information. The brush setting information is information for setting a figure drawn by the figure drawing unit 1312 to a figure in which a locus of a touch operation is drawn with a brush of a predetermined color. The airbrush setting information is information for setting a figure drawn by the figure drawing unit 1312 to a figure that draws a locus of a touch operation with an airbrush of a predetermined color.

  The straight line setting information is information for setting a graphic drawn by the graphic drawing unit 1312 to a line segment having a predetermined thickness and color connecting the start position and the end position of the touch operation. The rectangle setting information is a rectangle in which a figure drawn by the figure drawing unit 1312 has four sides of a line segment of a predetermined thickness and color, and a line segment connecting the start position and the end position of the touch operation is a diagonal line. The information to be set in the rectangle. The circle setting information is a circle in which a figure drawn by the figure drawing unit 1312 has a predetermined thickness and color as a circumference, the start position of the touch operation is the center of the circle, and the start position and the end position Is set to a circle whose radius is the circle connecting the line segments. The display setting information is not limited to the above.

  As an initial setting of the display system 1, for example, black pen setting information among the plurality of display setting information is stored in the display setting storage unit 133. Therefore, when a touch operation is performed with the initial setting, a figure that directly represents the locus of the touch operation is drawn on the screen with a black line having a predetermined thickness.

  The setting image storage unit 134 stores a plurality of setting image data. An image based on the set image data is referred to as a set image. Each setting image is an icon image representing each display setting information stored in the all display setting storage unit 132 or an image representing each display setting information in characters.

  As shown in FIG. 3, the change unit 135 includes a toolbar image display control unit 1351, a display determination unit 1352, a position determination unit 1353, and a display setting change unit 1354 and is stored in the display setting storage unit 133. It has a function of changing display setting information. When a touch operation is performed after changing the display setting information stored in the display setting storage unit 133, an image is displayed in the screen 11a of the display unit 11 according to the changed display setting information.

  The toolbar image display control unit 1351 displays a toolbar image including a plurality of setting images in a predetermined area in the screen 11 a of the display unit 11 based on the plurality of setting image data stored in the setting image storage unit 134. .

  FIG. 4 shows an example of the toolbar image. In FIG. 4, at the left end of the screen 11a, a black pen setting image 100A representing black pen setting information, a red pen setting image 100B representing red pen setting information, a blue pen setting image 100C representing blue pen setting information, and an eraser. An eraser setting image 100D representing setting information, a thick pen setting image 100E representing thick pen setting information, a brush setting image 100F representing brush setting information, an air brush setting image 100G representing air brush setting information, and straight line setting information. A straight line setting image 100H, a rectangular setting image 100I representing rectangular setting information, a circular setting image 100J representing circular setting information, a frame line image 100K surrounding them, and a frame line image 100L surrounding the outer periphery of the red pen setting image 100B Is displayed.

  Each of the setting images 100A to 100J has sides parallel to the X direction and the Y direction, and the length of the diagonal line is 5 cm to 15 cm in the screen 11a (100 pixels if the pixel pitch of the screen 11a is 0.5 mm). It is a rectangular image having 300 pixels). The rectangular setting images 100A to 100J are separated from each other at intervals of about 5 mm to 20 mm (10 pixels to 40 pixels when the pixel pitch of the screen 11a is 0.5 mm) in the screen 11a so as not to overlap each other. Are displayed side by side in a matrix of two columns with the X direction and the Y direction being the row direction and the column direction.

  As shown in FIG. 4, the toolbar image display control unit 1351 surrounds the outer periphery of any one of the setting images within the screen 11a by 5 mm to 20 mm (10 pixels if the pixel pitch of the screen 11a is 0.5 mm). A rectangular frame-shaped frame line image 100L composed of black lines with a thickness of about 40 pixels) is displayed. The frame line image 100 </ b> L is displayed so as to surround the outer periphery of the setting image representing the display setting information stored in the display setting storage unit 133 in the toolbar image 100. Therefore, in the example of FIG. 4, the display setting information stored in the display setting storage unit 133 is red pen setting information.

  The toolbar image display control unit 1351 does not always have to display the toolbar image as described above, and may be configured to switch between displaying and not displaying the toolbar image according to the touch operation by the user. For example, the toolbar image display control unit 1351 may be configured to delete the toolbar image after a predetermined time (for example, 5 seconds to 1 minute) after the display setting information is changed by the changing unit 135, or the toolbar image. In the non-display state, a toolbar image may be displayed when a touch operation is performed three times in succession on the same position in the left corner area of the screen 11a of the display unit 11. Good.

  When the position information is acquired by the touch panel unit 12, the display determination unit 1352 determines whether or not the toolbar image is displayed on the screen 11 a of the display unit 11 by the toolbar image display control unit 1351.

  When the display determination unit 1352 determines that the toolbar image is being displayed, the position determination unit 1353 determines whether the position indicated by the position information acquired by the touch panel unit 12 is in the toolbar image or the graphic drawing unit 1312 Is determined to be an area that can be drawn (that is, a work area), and if it is within the toolbar image, the position is other than the setting image representing the display setting information stored in the display setting storage unit 133. Judgment is made as to whether it is within the set image.

  When the position determining unit 1353 determines that the setting image is within the area where the setting image is displayed, the display setting changing unit 1354 displays the display setting information represented by the setting image stored in the display setting storage unit 133. Change the setting information.

  Therefore, according to the changing unit 135, for example, when the display setting information stored in the display setting storage unit 133 is black pen setting information, as shown in FIG. 4, the display unit 11 is currently displaying on the screen 11 a of the display unit 11. When a touch operation is performed with the stylus S on the red pen setting image 100B in the toolbar image 100, the display setting information stored in the display setting storage unit 133 is changed to the red pen setting information.

  In the example of FIG. 4, only the setting image corresponding to the display setting information for the drawing mode is displayed in the toolbar image, but an image representing the object editing mode or an image representing the sheet operation mode is displayed. As described above, the toolbar image display control unit 1351 may be configured. In such a case, when the touch operation is performed on the setting image, the changing unit 135 sets the mode stored in the touch setting storage unit 139 as the drawing mode and performs the touch operation on the image representing the object editing mode. Is performed, the mode stored in the touch setting storage unit 139 is set as the object editing mode. When a touch operation is performed on an image representing the sheet operation mode, the mode is stored in the touch setting storage unit 139. The mode is configured to be a sheet operation mode.

  Next, the setting image display control unit 1313 and the first time elapsed determination unit 136 will be described. The process of the setting image display control part 1313 based on the process of the 1st time passage judgment part 136 and the process of the 1st time passage judgment part 136 is one of the feature points of the display system 1 which concerns on this invention.

  The first time elapsed determination unit 136 determines whether or not a predetermined first specific time has elapsed since the last touch operation was performed. More specifically, the first time elapsed determination unit 136 stores the time at the end of the touch operation for displaying the graphic as an image and updates it as needed, and the start time of the newly performed touch operation. Then, it is determined whether or not the elapsed time from the last stored time is equal to or longer than the first specific time.

  Here, the touch operation for displaying the figure as an image is a touch operation on the work area in the screen 11a of the display unit 11 in the drawing mode. Hereinafter, after the first specific time has elapsed, The touch operation on the work area in the drawing mode is referred to as a first touch operation. Whether or not the touch operation corresponds to the first touch operation when the touch operation is performed is determined by the position determination unit 1353 and the first time elapsed determination unit 136. There is a time interval equal to or longer than the first specific time between the start point of the first touch operation and the end point of the touch operation immediately before the first touch operation.

  The setting image display control unit 1313 displays a setting image representing the display setting information stored in the display setting storage unit 133 in the screen 11a of the display unit 11 when the touch operation is performed. The distance from the position indicated by the position information is displayed in a set image display area within a predetermined first specific distance.

  In the present embodiment, the setting image display control unit 1313 performs the first touch operation, that is, the next touch operation for displaying the graphic as an image after the first specific time has elapsed. Then, a setting image representing the display setting information stored in the display setting storage unit 133 is displayed. More specifically, when the first touch operation is performed, the setting image display control unit 1313 controls the graphic drawing unit 1312 to prohibit drawing of the graphic corresponding to the first touch operation, and the corresponding graphic is displayed. Instead of displaying as an image, a setting image representing the display setting information stored in the display setting storage unit 133 is displayed in the setting image display area.

  The first specific time is, for example, 5 minutes to 30 minutes. The set image display area is a circular area whose distance from the position indicated by the position information at the start of the first touch operation (hereinafter referred to as “initial position”) is within the first specific distance. The first specific distance is a distance of 10 cm to 50 cm on the screen 11a of the display unit 11 (200 pixels to 1000 pixels if the pixel pitch of the screen 11a is 0.5 mm). The setting image displayed in the setting image display area is, for example, the same image as the setting image in the toolbar image, has sides parallel to the X direction and the Y direction, and the length of the diagonal line within the screen 11a. It is a rectangular image having a size of 5 cm to 15 cm (100 pixels to 300 pixels if the pixel pitch is 0.5 mm). For example, the rectangular setting image is displayed such that the lower right vertex is positioned at a position 0 cm to 5 cm to the left and 0 cm to 5 cm away from the initial position. Note that the setting image displayed in the setting image display area may not be the same as the setting image in the toolbar image. For example, an image obtained by enlarging or reducing the setting image in the toolbar image, or the display setting storage unit 133 A setting image or the like representing the display setting information stored in the text may be used.

  The configuration of the setting image display control unit 1313 and the first time passage determination unit 136 as described above is based on the work area after a long time (first specific time) has elapsed after the user performs a touch operation. The case where a touch operation (first touch operation) is performed is assumed. In such a case, in a general display system, a graphic corresponding to the first touch operation is displayed on the display screen. However, in the present embodiment, a graphic corresponding to the first touch operation is displayed on the screen 11a of the display unit 11. Instead of being drawn in, the setting image representing the display setting information stored in the display setting storage unit 133 is displayed in the setting image display area which is the area near the initial position of the first touch operation. .

  Note that the setting image display control unit 1313 may be configured to delete the displayed setting image based on the determination of the drawing start determination unit 138 regarding the first touch operation, as will be described later. Regardless of the determination of the start determination unit 138, the displayed setting image may be deleted after a predetermined time (for example, 0.5 seconds to 30 seconds) has elapsed since the setting image was displayed. Then, after the first touch operation, the displayed setting image may be deleted when the touch operation is performed again on the work area. Further, the setting image displayed by the setting image display control unit 1313 may continue to be displayed at the same position in the screen 11a until it is erased, may blink, or may be displayed at another position in the screen 11a. You may move.

  An example of the processing result of the setting image display control unit 1313 when the first specific time has elapsed will be described with reference to FIG. In FIG. 5, the locus of the first touch operation by the user is indicated by reference symbol P, the initial position of the first touch operation is indicated by reference symbol P1, and the boundary of the circular setting image display region is drawn by a two-dot chain line. A setting image indicated by reference sign Q and representing display setting information stored in the display setting storage unit 133 is indicated by reference numeral 200, and a lower right vertex of the setting image is indicated by reference sign R. Further, the toolbar image 100 shown in FIG. 4 is not displayed in the screen 11a in FIG.

  In the example of FIG. 5, assuming that the display setting information stored in the display setting storage unit 133 is red pen setting information, the same setting image 200 as the red pen setting image 100B shown in FIG. 4 is set in the screen 11a. It is displayed in the image display area Q, and the lower right vertex R of the setting image 200 is located at the upper left with respect to the initial position P1. Further, as described above, when a touch operation (first touch operation) is performed on the work area after the first specific time has elapsed, the graphic corresponding to the locus P of the first touch operation is not displayed in the screen 11a. Therefore, the locus P of the first touch operation is indicated by a broken line.

  When the initial position P1 is near the edge of the screen 11a, if the setting image 200 is displayed so that the lower right vertex R of the setting image 200 is located at the upper left with respect to the initial position P1, the setting image 200 is displayed in the screen 11a. There may be a case where the setting image 200 does not enter. Therefore, in such a case, the setting image display control unit 1313 sets the position of the setting image 200 displayed in the setting image display area Q with respect to the initial position P1 so that the entire setting image 200 enters the screen 11a. Is set at a position different from that displayed in the center of the screen 11a.

  For example, when the initial position P1 is near the upper right end of the screen 11a, the setting image display control unit 1313 sets the position of the setting image 200 displayed in the setting image display area Q to the lower left of the initial position P1, and the setting image 200 The setting image 200 is displayed such that the upper right vertex of is located at the lower left with respect to the initial position P1. When the initial position P1 is near the upper left end of the screen 11a, the setting image display control unit 1313 sets the position of the setting image 200 displayed in the setting image display area Q to the lower right of the initial position P1, and sets the setting image. The setting image 200 is displayed so that the upper left vertex of 200 is located at the lower right with respect to the initial position P1. When the initial position P1 is near the lower left corner of the screen 11a, the setting image display control unit 1313 sets the position of the setting image 200 displayed in the setting image display area Q to the upper right of the initial position P1, and the setting image 200 The setting image 200 is displayed so that the lower left vertex of is located on the upper right with respect to the initial position P1.

  Next, the drawing start determination unit 138 will be described. The processing of the drawing start determination unit 138 and the processing of the setting image display control unit 1313 based on the processing of the drawing start determination unit 138 are one of the feature points of the display system 1 according to the present invention.

  The drawing start determination unit 138 determines whether or not the object creation operation including the touch operation (first touch operation) on the work area in the drawing mode after the first specific time has passed satisfies a predetermined specific condition. Do. More specifically, the drawing start determination unit 138 stores the time at the start of the first touch operation that is the first operation of one or more touch operations included in the object creation operation. It is determined whether or not the object creation operation has been performed continuously for a second specific time determined in advance from the start of the touch operation, for example, for 1 to 2 seconds. The drawing start determination unit 138 determines whether or not the object creation operation has been continuously performed for the second specific time or, instead, or instead of the second predetermined time from the start position of the first touch operation. It may be determined whether the object creation operation is continuously performed up to a specific distance, for example, a position 1 cm to 2 cm away.

  In the present embodiment, when the object creation operation including the first touch operation is performed, when the drawing start determination unit 138 determines that the object creation operation is not continuously performed so as to satisfy the specific condition. The setting image display control unit 1313 displays a setting image representing the display setting information stored in the display setting storage unit 133 instead of displaying a graphic corresponding to each touch operation included in the object creation operation as an image. Display in the setting image display area. At this time, the setting image display control unit 1313 displays the setting image from the start time of the first touch operation included in the object creation operation to the end time of the object creation operation, that is, the second specific time (1 second to 2 seconds). ) Is displayed for a shorter time. When the drawing start determination unit 138 determines that the object creation operation is continuously performed so as to satisfy the specific condition, the setting image display control unit 1313 includes the graphic drawing unit 1312 in the object creation operation. The figure corresponding to each touch operation is displayed as an image after this determination. At this time, the setting image display control unit 1313 causes the figure drawing unit 1312 to start drawing of a figure corresponding to each touch operation included in the object creation operation during the object creation operation in the order of the touch operation. The display is performed from the start time of the first touch operation included in the object creation operation to the start time of drawing of the graphic, that is, for a time slightly longer than the second specific time (1 second to 2 seconds).

  As described above, in this embodiment, immediately after the first touch operation is performed, only the setting image is displayed, and thereafter, the object creation operation including the first touch operation is continued so as to satisfy the specific condition. The drawing of the figure corresponding to each touch operation included in the object creation operation is started, the setting image is erased as the drawing starts, and the object creation operation is not continuously performed. In such a case, the drawing corresponding to the object creation operation is not drawn, and the setting image is erased when the object creation operation ends.

  The configuration of the setting image display control unit 1313 and the drawing start determination unit 138 as described above is such that the user performs a touch operation on the work area after a long time (first specific time) has elapsed after performing the touch operation. It is assumed that (first touch operation) is performed and the object creation operation including the first touch operation is continued to satisfy a specific condition. In such a case, in the present embodiment, first, a setting image representing the display setting information stored in the display setting storage unit 133 is displayed in the setting image display area, and then the object creation operation satisfies the above specific condition. After that, a graphic corresponding to each touch operation included in the object creation operation is drawn in the screen 11a, and the setting image is deleted. Note that the display mode of the setting image in this case is as described above.

  According to the present embodiment, for example, the user can check the display setting information stored in the display setting storage unit 133 from the setting image displayed by the first touch operation, and the display setting information is desired. If it is, the figure corresponding to the object creation operation can be drawn by continuing the object creation operation.

  FIG. 6 is a flowchart showing processing when a touch operation (hereinafter referred to as “target touch operation”) is performed on the screen 11 a of the display unit 11 in the drawing mode. When the target touch operation is performed, the position information is acquired by the touch panel unit 12, the position information and the acquired time are stored in the touch operation information management unit 1311 of the touch operation image display control unit 131, and then the determination in step S1 is performed. Done.

  In step S <b> 1, the display determination unit 1352 determines whether a toolbar image is being displayed in the screen 11 a of the display unit 11. If it is determined that the tool bar image is being displayed, the process proceeds to step S2. If it is determined that the tool bar image is not being displayed, the process proceeds to step S5.

  In step S2, the position determination unit 1353 determines whether or not the position where the target touch operation has been performed is in the toolbar image. If it is determined that the determination result is within the toolbar image, the process proceeds to step S3. If the determination result is not within the toolbar image, the process proceeds to step S5.

  In step S <b> 3, the position determination unit 1353 displays a setting image representing display setting information stored in the display setting storage unit 133 among the setting images displayed in the toolbar image for the position where the target touch operation is performed. It is determined whether or not the setting image is in another setting image. If it is determined that the determination result is in another setting image, the process proceeds to step S4. If it is determined that the determination result is not in another setting image, the process for the target touch operation is ended.

  In step S4, the display setting change unit 1354 changes the display setting information being stored in the display setting storage unit 133 to display setting information represented by another setting image displayed at the position where the target touch operation has been performed. change. When the display setting information is changed, the process for the target touch operation is terminated.

  In step S5, the first time elapsed determination unit 136 determines whether the time at the start of the target touch operation is after the first specific time has elapsed since the end of the touch operation immediately before the target touch operation. . When it is determined that the determination result is not after the first specific time has elapsed, the process proceeds to step S6, and when it is determined that the first specific time has elapsed, the process proceeds to determination at step S7.

  In step S6, the graphic drawing unit 1312 draws a graphic corresponding to the locus of the target touch operation according to the display setting information stored in the display setting storage unit 133.

  In step S <b> 7, the setting image display control unit 1313 displays a setting image representing the display setting information stored in the display setting storage unit 133 on the display unit 11 instead of drawing a graphic corresponding to the locus of the target touch operation. It is displayed in the setting image display area in the screen 11a. When the setting image is displayed instead of drawing the figure corresponding to the target touch operation, the drawing start determination unit determines that the object creation operation including the target touch operation is continuously performed so as to satisfy the specific condition. If the determination is made at 138, the setting image is erased from the screen 11a of the display unit 11 after the determination, and a figure corresponding to the target touch operation is drawn instead.
