|Title:||VIDEO DISPLAY CONTROL DEVICE|
A video display control device comprises: a video signal processing unit which corrects a video signal on the basis of control data which a control data generator unit generates and outputs to a display a post-correction video signal; and a backlight control unit which controls emitted light brightness of a backlight on the basis of the difference between the average brightness of the video signal and the average brightness of the post-correction video signal. The control data generator unit allocates to a low-tone region a portion of a high-tone region dynamic range of the video signal in which a video signal corresponding to a black band region is excluded. The backlight control unit controls the emitted light brightness of the backlight to eliminate an increase or decrease in the average brightness of a video which is displayed in a screen according to an increase or decrease in the average brightness of the post-correction video signal with respect to the average brightness of the video signal.
