Abstract
A video display control device includes a video signal processing section that corrects a video signal and outputs a video signal after correction to a display, and a backlight controlling section that controls a light emission amount of a backlight. A control data generating section allocates to a low gradation region of the video signal a high gradation region dynamic range of the video signal in which a video signal corresponding to a black band region is excluded. The backlight controlling section controls a light emission luminance of the backlight so as to cancel out an increase or a decrease in the mean luminance of the video displayed on a screen.
