  The functions of the control unit 201, the position specifying unit 204, and the shift amount calculating unit 205 are realized by the CPU 118.

  Here, the principle of displaying a stereoscopic image on the 3D display unit 207 will be briefly described with reference to FIGS.

  In the first place, the left and right eyes of humans are 6 to 6.5 cm apart on average, so the pictures you see are slightly different. For this reason, the picture captured by the left and right eyes can be felt three-dimensionally. The principle of stereoscopic vision uses this fact, and stereoscopic vision is possible by including images that are slightly different from the image for the left eye and the image for the right eye separately.

  Therefore, for example, using the above-described drawing device 200, the control unit 201 reads out the left-eye image and the right-eye image stored in the left-eye image memory and the right-eye image memory, respectively, and in the horizontal direction. Divide into rows of a predetermined width. Then, the left-eye image and the right-eye image are alternately displayed on the 3D display unit 207.

  The 3D display unit 207 is configured, for example, by inserting a switch liquid crystal panel between a TFT liquid crystal panel and a backlight, as shown in FIG. When the image is displayed in 3D, the parallax barrier B is made opaque. Then, the left-eye image L and the right-eye image R are alternately displayed on the TFT liquid crystal panel, and the column generated from the left-eye image is only in the left eye, and the column generated from the right-eye image is only in the right eye. As a result, the slightly different left-eye image and right-eye image displayed on the 3D display unit 207 enter the left eye and the right eye, respectively, and an image composed of the left-eye image and the right-eye image is stereoscopically viewed.

  For example, the left-eye image and the right-eye image on the drawing memory shown in FIG. 11 can be stereoscopically viewed using a 3D display. Referring to FIG. 12, the image for the left eye and the image for the right eye on the drawing memory are displayed on the odd-numbered lines only by the action of the switch liquid crystal panel (polarizing filter) shown in FIG. The image displayed on the line enters only the left eye. Thereby, stereoscopic vision becomes possible.

  In the present embodiment, the 3D display unit 207 of the drawing apparatus 200 is configured by the 3D display as described above, but may be configured in other forms. Further, the left-eye image and the right-eye image may be alternately drawn without using the 3D display.

  In the present embodiment, the left-eye image and the right-eye image in the drawing memory 206 are shown as being divided into left and right on the memory, but are alternately divided into upper and lower divisions and odd and even columns. It doesn't matter in the form.

  Next, a method for generating a right eye image and a left eye image in the drawing apparatus 200 will be described.

  Conventionally, as described above, the shift amount between the right-eye image and the left-eye image is determined for each figure. Therefore, the right-eye image and the left-eye image can be simply moved in parallel regardless of the position of the figure. (See Japanese Patent Application No. 2002-250469).

  This can be expressed by the following equation (1).

  FIG. 13 is a diagram for explaining a conventional calculation formula for the shift amount.

  W is the distance of the eye width between the left eye 16 and the right eye 17 constituting a specific viewpoint, a is the distance from the center point of the eye width of the left eye 16 and the right eye 17 to the position 11 indicating the reference position, and b is the reference position The distance (the distance in the z-axis direction from the 11th position to the 15th position) indicating the amount of rising in FIG. Here, the reference position is the position in the x-axis direction of the intersection of the perpendiculars drawn from the center point of the left and right eye widths with respect to the display 14.

  Using equation (1), referring to FIG. 13, when the amount of rise at position 11 is compared with the amount of rise at position 18, the amount of rise at position 18 (from position 18 to position 22). It can be seen that the distance (b) is greater than the amount b (the distance from the position 11 to the position 15). When such a floating amount is expressed perpendicularly to the display 14, it is as shown in FIG. Referring to FIG. 14, it can be seen that the amount of floating increases as the distance from the center of display 14 increases.

  FIG. 4 is a diagram for explaining the amount of floating of an image in a state where a person with two left and right eyes is looking at the display 14 from the front in the embodiment of the present invention.

  Referring to FIG. 4, when the left eye 16 and the right eye 17 are set as specific viewpoints, 11 on the display indicates the intersection of the display 14 with the perpendicular drawn from the center point of the left eye 16 and the right eye 17. Instead of drawing an image at the 11 position on the display 14, the image is shifted left and right by the same displacement, and an image that can be seen only by the right eye 17 is drawn at a 12 position on the display 14, and only the left eye 16 is seen at the 13 position When the image is drawn, the image appears to appear at the intersection 15 of the straight line connecting the position 12 and the right eye 17 and the straight line connecting the position 13 and the left eye 16.

  In addition, in order to display the image at the 18th position in the same manner, instead of drawing at the 18th position, an image that can be seen only by the right eye 17 is drawn at the 19th position, and the left eye 16 at the 20th position. Draw an image that only looks. In this case, the amount of shift between the image for the right eye and the image for the left eye is drawn by reducing the amount of shift compared to the case where the image exists at the position of 11. Then, the image appears to float at the position 21.

  When the amount that appears to rise up is expressed perpendicularly to the display 14, as shown in FIG. 5, the same amount is displayed at any position on the display 14, and the amount is shown in parallel. As a result, the distortion of the 3D image in which the amount of floating increases as the distance from the reference position of the display 14 increases can be suppressed.

  A calculation formula for such a shift amount that gives the same amount of rise regardless of the position of the display 14 is expressed by the following formula (2).

  FIG. 6 is a diagram for explaining the calculation formula (2) of the shift amount between the right-eye image and the left-eye image in the embodiment of the present invention.

  Referring to FIG. 6, W is the distance of the eye width between the left eye 16 and the right eye 17 constituting a specific viewpoint, and a is from the center point of the eye width of the left eye 16 and the right eye 17 to the 11 position indicating the reference position. , B is a distance indicating the amount of rising at the reference position (distance in the z-axis direction from the 11 position to the 15 position), and x is the x-axis direction from the 11 position indicating the reference position to the 18 position. Shows the distance.

  By using the expression (2), the value of x increases as the image moves away from the reference position, so that the shift amount d decreases. For example, in the image shown in the graphic 18 shown in FIG. 6, the shift amount d is smaller than the shift amount d of the image at the position 11 when Expression (2) is used. By doing so, the position where the image at the position 18 appears to appear is 21 and the distance is the same as b.

  Next, an operation until multimedia content data is displayed in 3D on the 3D display unit 207 in the embodiment of the present invention will be described.

  Here, multimedia content data (hereinafter referred to as “content data”) is composite content data that is played back at the same time by adding still images and moving images that are not related to raster graphics and vector graphics, or by combining them with music. is there. Hereinafter, although content data is described as a still image, it may be one frame of a moving image.

  FIG. 7 is a flowchart for explaining the movement from the generation of the right-eye image and the left-eye image to the 3D display when the content data is raster graphics.

  Referring to FIG. 7, first, it is determined whether content data has been acquired by control unit 201 (step S1). If the control unit 201 determines that the content data has not been acquired, the program ends (NO in step S1). On the other hand, if the control unit 201 determines that the content data has been acquired, it is determined whether all pixels have been processed (step S2).

  If the control unit 201 determines that all the pixels are not processed, the pixel to be processed is acquired and the coordinates from the reference position are specified (step S3). Thereafter, the depth information of the object is acquired (step S4). The depth information of the object may be set by the user or may be set in advance.

  Based on the set depth information, the shift amount is calculated for each pixel using the above-described equation (2) (step S5). Then, the right eye data and the left eye data are drawn on the VRAM by shifting the pixels by the calculated shift amount (step S6). The VRAM corresponds to the drawing memory 206 shown in FIG.

  Since the shift amount is calculated for each pixel and the shift amount differs depending on the pixel position, when drawing the right-eye data and left-eye data, a blank portion is generated when the shift amount is large, and an overlapping portion is generated when the shift amount is small. Arise.

  When a blank portion occurs, the pixel values on both sides may be averaged or α blending may be performed. Conversely, when an overlapping portion occurs, the overlapping pixel values may be averaged for drawing.

  Thereafter, when the right-eye data and the left-eye data are read from the VRAM and output to the 3D display unit 207, the content is displayed three-dimensionally (step S7).

  If it is determined in step S2 that all pixels have been processed, the program ends.

  FIG. 8 is a flowchart for explaining the movement from the generation of the right-eye image and the left-eye image to the 3D display when the content data is vector graphics.

  Referring to FIG. 8, first, it is determined whether content data has been acquired by control unit 201 (step S11). If the control unit 201 determines that the content data has not been acquired, the program ends (NO in step S11). On the other hand, if the control unit 201 determines that the content data has been acquired, it is determined whether all objects have been processed (step S12).

  If the control unit 201 determines that not all objects have been processed, the object to be processed is acquired and the coordinates from the reference position are specified (step S13). Thereafter, the depth information of the object is acquired (step S14). The depth information of the object can be set for each pixel by the user.

  Based on the set depth information, the shift amount is calculated for each pixel using the above-described equation (2) (step S15). Then, the right eye data and the left eye data are drawn on the VRAM by shifting the pixel by the calculated shift amount (step S16).

  Thereafter, when the right-eye data and the left-eye data are read from the VRAM and output to the 3D display unit 207, the content is displayed three-dimensionally (step S17).

  If it is determined in step S12 that all objects have been processed, this program ends.

(Modification)
In the above embodiment, the calculation formula (2) has been described as an example in which it appears to float up by using the intersection method, but it can also be applied to the case where it appears to be retracted using the parallel method.

  Even in this case, only the sign of the shift amount d shown in FIG. 6 is reversed, and the shift amount can be calculated by the above-described calculation formula (2).

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
