Patent ID: 7924251

Claim:
An image processing method for a hold type display, comprising: evaluating a video signal; dividing the video signal for one frame period into a plurality of sub frames; and distributing at least a part of luminance components of the video signal of a predetermined sub frame to the video signal of other sub frames of which luminance components are not saturated, wherein an integrated luminance in one entire frame period is kept constant, and a drive frequency is set higher than a frame frequency, wherein a response time is shorter than a sub frame period, or the response time is longer than the sub frame period, and overdrive processing is performed when the response time is longer than the sub frame period, and wherein in a case where a first response time at a time of decreasing a gradation value of the hold type display is faster than a second response time at a time of increasing the gradation value, a first luminance component distributed to a first sub frame just before the predetermined sub frame is not lower than a second luminance component distributed to a second sub frame just before the first sub frame, and in a case where the second response time is faster than the first response time, the first luminance component is not higher than the second luminance component.
