Removing noise by adding the input image to a reference image |
摘要 |
An image processing device (10) removes noise from an input image by adding the input image to a reference image, and includes: a motion estimation unit (1) which generates motion information for each of blocks of the input image; a motion compensation unit (3) which generates a motion-compensated reference image; a block distortion amount calculation unit (5) which calculates a block distortion amount for each of blocks of the motion-compensated reference image; an addition ratio calculation unit (6) 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 (4) 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.
