IMAGE PROCESSING DEVICE AND METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

The present technique relates to an image processing device, an image processing method, a program, and a recording medium that enable more accurate block noise correction without degradation of image quality.;A motion predicting unit detects, from a criteria image and a reference image, the motion vector of each of blocks constituting an image. A motion compensating unit generates a motion-compensated image by performing motion compensation on the reference image, using the motion vectors. A correction value calculating unit 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, the boundary difference value being a difference value with respect to the pixel value of a boundary pixel in a boundary portion adjacent to an adjacent block in the current block. An adding unit adds the correction value to the pixel value of the current pixel in the motion-compensated image. The present technique can be applied to image processing devices.
