Abstract

An image processing device includes a motion predicting unit that detects, from a criteria image and a reference image, the motion vector of each of blocks constituting an image, a motion compensating unit that generates a motion-compensated image by performing motion compensation on the reference image, using the motion vectors, a correction value calculating unit that calculates a correction value for correcting the pixel value of a current pixel in a current block in the motion-compensated image based on a boundary difference value between the criteria image and the motion-compensated image, and an adding unit that adds the correction value to the pixel value of the current pixel in the motion-compensated image.

First claim

The invention claimed is:

1. An image processing device comprising:
processing circuitry including a processor and a memory encoded with instructions configured to:
detect, from a criteria image and a reference image, a motion vector of each block in an image;
generate a motion-compensated image by performing motion compensation on the reference image, using the motion vector;
calculate a correction value for correcting a pixel value of a current pixel in a current block in…
