Abstract:
1. An image display device, which forms, on a screen, an image displayed on a first display panel and an image displayed on a second display panel superposed with each other, comprising: an acquisition unit configured to acquire a video signal of successive respective frames; a frame rate converting unit configured to perform frame-rate-convert-processing for outputting intermittent frames whose frame rate is lower than that of the successive respective frames; a first generation unit configured to generate a low frequency video signal of the intermittent frames; a second generation unit configured to calculate a ratio of a signal value of a video signal of an acquired frame acquired by said acquisition unit to a signal value of the low frequency video signal of an intermittent frame, wherein the intermittent frame is every other frame of the successive respective frames, to generate a high frequency video signal having a signal value based on the calculated ratio, and to output the generated high frequency video signal to the first display panel; and a third generation unit configured to calculate a ratio of a signal value of the video signal of the intermittent frame to a signal value of the high frequency video signal of the intermittent frame, to generate an adjusted low frequency video signal having a signal value based on the calculated ratio, and to output the generated adjusted low frequency video signal to the second display panel.
