Abstract

There are provided image processing apparatus and method, in which an image signal expressed by a plurality of bits is continuously inputted every pixel, the input image signal is compared with a reference image signal, a change in image is detected, and when the change in image is not detected as a detection result, a quality improving process of the image signal is executed by using a plurality of image signals which are obtained for a period of time when the image change is not detected, and when the image change is detected as a detection result, the input image signal is outputted without performing the quality improving process, and when the image change is not detected as a detection result, the image signal which was subjected to the quality improving process is outputted.
