Patent ID: 8902364

Claim:
An image display apparatus which divides a 1-frame period of input image data into a plurality of periods and displays image data in the respective divided periods, comprising: a generation unit configured to generate high frequency component data of the input image data; a detection unit configured to detect a pixel position having maximum amplitude of the high frequency component data in a predetermined area based on image area on which calculation for generating the high frequency component data of the input image data is executed; and a high frequency component control unit configured to distribute the high frequency component data for the image data in the respective divided periods based on a gradation at the detected pixel position of the input image data and the maximum amplitude of the high frequency component data to make the amplitude of the generated high frequency component data fall within a difference between the gradation at the detected pixel position of the input image data and one of 0 gradation or a maximum gradation according to a number of bits for 1 pixel data.
