FIELD: physics, computer engineering.SUBSTANCE: invention relates to computer engineering. The image processing device includes an extraction means which performs motion compensation using as a reference frame a frame formed from a decoded image, and using a motion vector in an image that was encoded, and for extracting a motion compensation image corresponding to a predicted image from the reference frame; a means of generating an image with intra-frame prediction which performs intra-frame prediction for the current frame for which the predicted image is to be generated, and which generates an image with intra-frame prediction, which corresponds to the predicted image from a portion of the decoded image; and a means of generating a predicted image, which generates a predicted image by performing filter processing to compensate for high-frequency component shortcomings in the motion compensation image extracted by the extraction means, and an image with intra-frame prediction generated by generating an image with intra-frame prediction using correlation in a temporal direction which is included in the motion compensation image and the image with intra-frame prediction.EFFECT: providing high encoding efficiency without increasing the volume of transmission of motion vectors in a stream.13 cl, 32 dwg |
