Abstract:
1. An image display apparatus using a fixed-pixel device for displaying an image based on a video signal, comprising: a black correction processor which performs black correction processing for the video signal using average luminance level information of the video signal; a contrast controller which controls a contrast of the video signal; and a controller, wherein the contrast controller which performs a control to increase the contrast when the amount of the black correction by the black correction processor is greater than or equal to a predetermined value; the controller performs the black correction processing when the average luminance level information is greater than or equal to a predetermined value, and does not perform the black correction processing in a luminance range less than or equal to the predetermined value, and controls the contrast controller so as to control the contrast of the video signal according to the amount of the black correction of the video signal by the black correction processor.
