ABSTRACT:
A display apparatus is capable of adapting sufficiently to an increase in the display frequency even when using an optical modulation element which has a fairly low response speed and can rewrite an image at a high speed. The display apparatus separately performs mapping of display data for an optical modulation element of each pixel and application of gradation information. The display apparatus divides a display period of one frame into a plurality of sub-frames, controls the input value for the optical modulation element independently per each sub-frame in the plurality of sub-frames, and displays an image with a gradation display using the optical modulation element.
