Abstract:
1. An image display device having an optical modulation element, which modulates light emitted from a light source according to display information, and displays a display image based on the display information, in a predetermined color space, the image display device comprising: a unit adjusting an amount of illumination light with respect to light emitted from a light source based on brightness information of brightness of a display image based on a display information; a color conversion processing unit that performs a color conversion process so that the display image can be color-reproduced, and both a color space of the display image obtained when the amount of illumination light is not adjusted and a color space of the display image obtained when the illumination light is adjusted define a predetermined color space; a display and driving unit that drives an optical modulation element based on the display information having been subjected to the color conversion process to display the display image; and a color conversion information storage unit that stores a plurality of conversion tables corresponding to the brightness information, each of the plurality of conversion tables associating each input pixel value corresponding to each color with each output pixel value for making the display image color-reproduced within the predetermined color space in correspondence with each input pixel value, wherein, when the color conversion processing unit performs the color conversion process, the color conversion processing unit converts each input pixel value for each color, which corresponds to each pixel, included in the display information into each output pixel value based on one of the plurality of conversion tables corresponding to the brightness information.
