Abstract
An image processing device () removes noise from an input image by adding the input image to a reference image, and includes: a motion estimation unit () which generates motion information for each of blocks of the input image; a motion compensation unit () which generates a motion-compensated reference image; a block distortion amount calculation unit () which calculates a block distortion amount for each of blocks of the motion-compensated reference image; an addition ratio calculation unit () which calculates an addition ratio of a block of the motion-compensated reference image so that the addition ratio decreases as the block distortion increases; and an addition unit () which perform weighted sum on a pixel value of the block of the motion-compensated reference image and a pixel value of a block of the input image, using the addition ratio.
