Abstract
An image processing device includes a target correction amount calculating unit operable to calculate a target correction amount based on input image signals, a frame memory operable to store the input image signals, and a scene change amount calculating unit operable to calculate a scene change amount based on an input image signal of a present frame and an input image signal of a previous frame. Moreover, the image processing device includes a correction amount calculating unit operable to calculate a correction amount for the input image signal of the present frame, based on the target correction amount and the scene change amount, and a correcting unit operable to perform image quality correction to the input image signal of the present frame to generate a corrected input image signal, thereby outputting a corrected input image signal as an output image signal.
