Abstract
An image processing apparatus detecting, from an input image, a still-zone area disposed at an edge of the input image and displaying a same image continuously, the apparatus including: a difference calculation mechanism calculating a difference between pixel values of pixels located at a same position of the input image in different frames with each other for each pixel of the input image; a pixel-motion-information generation mechanism generating pixel-motion information indicating whether there is a change in the pixel values of the pixels of the input image on the basis of the difference; and a first detection mechanism comparing the pixel-motion information of a plurality of the pixels arranged in a first direction in the input image, and detecting a boundary position in the first direction between the still-zone area and an effective area excluding the still-zone area in the input image.
