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.

摘要： There is provided an apparatus including: a low-bit criterion image generation unit that reduces a bit number assigned to a pixel in a criterion image and generates low-bit criterion image data; a low bit reference image generation unit that reduces a bit number of a reference mage and generates low-bit reference image data; and a motion vector information generation unit that detects a block-unit local motion vector from the low-bit criterion/reference images and calculates reliability of the detected local motion vector. By reducing the image bit number, it is possible to detect a local motion vector in a simple configuration. By calculating a global motion vector using a local motion vector according to reliability, even if a local motion vector is detected from an image of the reduced bit number, it is possible to calculate a global motion vector at higher accuracy.
