Patent ID: 8675978

Claim:
An image processing apparatus ( 501 ) comprising: filter control unit ( 511 ) configured to perform, on the basis of an intra prediction mode, filter processing turned on or off as to neighboring pixels that are adjacently located to a current block for intra prediction, the neighboring pixels subjected to the filter processing turned on or off being used as reference pixels for the intra prediction of the current block; intra prediction unit ( 171 ) configured to perform intra prediction on the current block using the reference pixels to generate a prediction image; and decoding unit ( 162 ) configured to decode encoded image data using the prediction image, wherein the neighboring pixels are not included within the current block, wherein the filter processing changes value of respective pixels being filtered, wherein the filter control unit determines filter processing on or filter processing off as to the neighboring pixels on the basis of a mode number of the intra prediction mode, wherein the filter control unit determines filter processing on or filter processing off on the basis of a control data indicating whether or not to perform filter processing on the current block, and wherein at least one of the filter control unit, the intra prediction unit, and the decoding unit is implemented via a processor.
