Abstract:
1. An image processing apparatus for generating image data to be supplied to an image display apparatus which inverts a drive polarity of display elements in each sub-frame of plural sub-frames formed from a frame of a moving picture to display the moving picture, the image processing apparatus comprising: a generator configured to generate a first sub-frame and a second sub-frame from a frame of interest of a moving picture; a detector configured to detect a difference between a picture of the first sub-frame and a picture of the second sub-frame; an accumulator configured to accumulate the difference as a cumulative value; a calculator configured to calculate a correction value of a picture of the first sub-frame and a picture of the second sub-frame based on the cumulative value; and a corrector, configured to employ the correction value so as to correct the picture of the first sub-frame and the picture of the second sub-frame, and to subtract a first value based on the correction value from the cumulative value, wherein the corrector is operable to add a second value of approximately half the correction value to one of the picture of the first sub-frame and the picture of the second sub-frame, and to subtract the second value from the other one of the picture of the first sub-frame and the picture of the second sub-frame so as to decrease a difference between an absolute value of the picture of the first sub-frame and an absolute value of the picture of the second-frame.
