摘要

In cases where the amount of gradation transition is greater than a threshold value, a modulation processing section corrects image data D of a current frame by making an interpolation calculation with reference to a look-up table, and output the image data D thus corrected. In cases where the amount of gradation transition is not more than the threshold value, the modulation processing section directly outputs the image data D of the current frame. Furthermore, in one embodiment of the present invention, the look-up table contains, as output image data D2 corresponding to a case where the image data D of the current frame is identical to image data D0 of a previous frame, a value which is neither of the image data D of the current frame and the image data D0 of the previous frame and by which output image data D2 corresponding to the inputted image data D and D0 of the previous and current frames is calculated according to the interpolation calculation in cases where the amount of gradation transition is greater than the threshold value. With this, an image display apparatus is realized which can be balanced between a reduction in circuit size and an improvement in display quality at a higher level.
