ABSTRACT:
An image processing apparatus includes a difference generation section and a histogram generation section. The difference generation section generates picture differences between frames of a moving picture in units of pixels, based on a present signal of the moving picture and a noise-eliminated frame-delayed signal acquired by subjecting the present signal to a process of eliminating noise and a process of delaying the present signal by one frame. The histogram generation section generates a histogram indicating a level distribution of part of the generated picture differences from which picture differences corresponding to pixels where a picture change not less than a threshold occurs are excluded.
