Claim:
1. An image processing apparatus comprising: a selecting unit configured to select, from a plurality of blocks with different sizes, a block with predetermined size as a current block for intra prediction; a filter unit configured to perform filter processing on neighboring pixels that are adjacently located to the current block for intra prediction using filter coefficients with values set according to a block size of the current block for the intra prediction; a filter controlling unit configured to control the filter processing so as to perform the filter processing turned on or off as to the neighboring pixels on the basis of a mode number of an intra prediction mode; an intra prediction unit configured to perform intra prediction on a current pixel within the current block using the neighboring pixels as reference pixels for the intra prediction to generate a prediction image; and an encoding unit configured to encode image data using the prediction image, wherein the selecting unit, the filter unit, the filter controlling unit, the intra prediction unit and the encoding unit are each implemented via at least one processor.
