Patent ID: 7952597

Claim:
An image display device for displaying images, comprising: a display section which displays an image of an input image signal on a display screen; an image processing section which performs a luminance correction operation which lowers a luminance level of at least one predetermined region of the display screen relative to the luminance level of at least another predetermined region of the display screen if a static image is displayed on the at least one predetermined region of the display screen when the image of the input image signal is displayed on the display screen of the display section: and a control section which controls the image processing section; wherein, when an accumulated elapsed-time of the static image, after initial lighting of the image display device, displayed on the at least one predetermined region of the display screen exceeds a predetermined time, the control section controls the image processing section so that the image processing section does not perform the luminance correction operation to lower the luminance level of the at least one predetermined region of the display screen even if the static image is displayed on the at least one predetermined region after the predetermined time, and wherein the predetermined time is a time when a luminance difference becomes equal to or less than a given value, the luminance difference indicating difference in luminance between the static image displaying part and the moving image displaying part when an entire white signal is displayed on the screen in both the static image displaying part and the moving image displaying part.
