Abstract:
1. A color reproducing method for a three-dimensional image display in a three-dimensional image display apparatus provided with a shading mask with a minute aperture array, having minute aperture parts, in front of a color display device, each minute aperture part being provided with a color filter composed of a red-light transmitting part, a green-light transmitting part, and a blue-light transmitting part, said method comprising: a corresponding step of, between the respective red-transmitting part, the green-transmitting part, and the blue-light transmitting part of the color filters and respective red, green, and blue sub-pixels of the color display device, corresponding the light transmitting parts and the sub-pixels that have a same color and exist in a same parallax image pixel region to each other, a setting step of setting such that visual angles between the respective centers of the red-light transmitting part, the green-light transmitting part, and the blue-light transmitting part of the color filters become equal, in an identical parallax image pixel region, to visual angles between the respective centers of the red sub-pixel, the green sub-pixel, and the blue sub-pixel of the color display device, a display step of always displaying the red sub-pixel, the green sub-pixel, and the blue sub-pixel which belong to an identical parallax image pixel region at a fixed area ratio in a lighted condition, and a color reproducing step of, at a viewing position of the three-dimensional image display apparatus at an optimal viewing distance, performing color reproduction while maintaining the ratio of brightness of the three RGB primary colors at a predetermined value in each of the respective parallax image pixels.
