<P>PROBLEM TO BE SOLVED: To appropriately control display luminance of a video signal in which one image is constituted by a plurality of frames. <P>SOLUTION: An image display device includes: a display panel; a calculation circuit that calculates a luminance control value, which is a parameter for controlling display luminance, for each frame of a video signal to be displayed on the display panel; and a luminance control circuit that controls the display luminance of the frame using the luminance control value calculated by the calculation circuit. Further, when the video signal is a video signal in which one image is constituted by a plurality of frames, the luminance control circuit applies a same luminance control value to the plurality of frames constituting one image, or decreases the difference of the luminance control values applied to the plurality of frames constituting one image to be lower than a predetermined value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
