Abstract:
1. An image display device having an optical modulation element, which modulates light emitted from a light source according to display information, and displaying a display image based on the display information, 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 on brightness of a display image based on a display information; a color conversion processing unit that performs a color conversion process according to the brightness information with respect to the display information so that the display image can be color-reproduced within a predetermined color space, the color conversion processing unit performs the color conversion process with respect to the display information such that the display information can also be subjected to a gray-scale characteristic correction process corresponding to a gray-scale characteristic of an optical modulation element; a gray-scale range change processing unit that performs a gray-scale range change process of changing a gray-scale range of the display information by increasing each pixel value, corresponding to each pixel, included in the display information based on the brightness information, and a display and driving unit that drives the optical modulation element based on the display information having been subjected to the gray-scale range change process and the color conversion process to display the display image.
