ABSTRACT:
An image display control device is capable of performing video image correction in real time. An effective pixel evaluation area Z1corresponding to one frame is set in a statistical information acquisition section. The statistical information acquisition section finishes a statistical value acquisition process after acquiring a statistical value of the effective pixel evaluation area Z1, and calculation of a correction coefficient and the like using the statistical value is completed within the remaining time of the one frame period. When input of an image signal of the next frame is started, the image display control device performs image correction using the calculated correction coefficient. The image display control device can calculate a backlight luminance after reduction in luminance at the same time as the correction coefficient.
