摘要： A pseudo-tone processing means color-reduces each RGB component of incoming display data using pseudo-tone processing. A frame memory stores the color-reduced display data before feeding it to a display through a drive means. Color reduction is performed so that the tone number of each RGB component after color reduction is G component>R component>B component. Color reduction is unequally performed in a manner which reflects contributions of each RGB component to brightness.

摘要： On the display screen of a video signal display device, when the emission amount is monotonically lowered toward the screen periphery from a certain point (screen center), if there are a plurality of regions that viewers notice easily (such as faces), then correction by monotically decreasing the emission amount cannot always raise the signal level in the regions that are noticed, and it may not be possible to obtain a sufficient sense of brightness. In the video signal processing device, a multiple object detection portion detects a plurality of objects that are included in a unit image, and a correction gain is calculated such that when the unit image is displayed on the display device, a point on the display screen at which an emission amount that is lower than the emission amount on the display screen at a point that is substantially in the center between any two objects is in a region between the points substantially in the center of the two objects, and the input video signal is corrected with that correction gain. Thus, it is possible to maintain a sense of brightness about a plurality of objects on the display screen that are readily noticed by viewers, while suppressing power usage by the display device that displays the video signal.
