Abstract:
1. A display apparatus employing a system for separately performing mapping of display data for an optical modulation element of each pixel of all pixels forming an image to be display and application of gradation information, wherein: each frame of said image is divided into a plurality of sub-frames; an input value for said optical modulation element of each pixel is controlled independently per each sub-frame in said plurality of sub-frames; said image is displayed with a gradation display obtained, using luminance amplitude modulation of each sub-frame, by applying the input value to said optical modulation element of each pixel during each sub-frame; first gradation information is applied simultaneously with said mapping of the display data for said pixels; second gradation information is applied for said pixel independently of said mapping; and said luminance amplitude modulation is performed per sub-frame simultaneously using said first gradation information and said second gradation information for obtaining said gradation display.
