Abstract:
1. An image processing apparatus comprising: circuitry configured to decode an encoded image; add together an image that has been decoded and a prediction image, and generate a decoded image; perform motion compensation using, as a reference frame, a frame formed of the decoded image and using a motion vector in the encoded image, and extract a motion compensation image corresponding to the prediction image from the reference frame; perform intra-frame prediction for a present frame for which the prediction image is to be generated, and generate an intra-prediction image corresponding to the prediction image from a portion of the decoded image; and generate the prediction image by performing a filtering process to compensate the extracted motion compensation image and the generated intra-prediction image for high-frequency components by utilizing correlation in a time direction that is included in the extracted motion compensation image and the generated intra-prediction image, generation of the prediction image including: applying a low-pass filter to a difference image between the extracted motion compensation image and the generated intra-prediction image, applying a high-pass filter to an image obtained by applying the low-pass filter, and adding the image obtained by applying the low-pass filter and an image obtained by applying the high-pass filter to the generated intra-prediction image.
