<P>PROBLEM TO BE SOLVED: To reduce block noise from the whole image data to be decoded while controlling effects reducing the block noise, for each feature of noise in the block boundary. <P>SOLUTION: An image processor is configured as follows. A position control part 31 calculates a distance from a block boundary position for each block and that of from a block boundary position of each pixel on the basis of block size information and a block boundary initial position so as to generate position control information of each pixel. A block noise detection part 33 detects block noise feature information at the block boundary position on the basis of the position control information. A noise reduction processing part 34 reduces noise of each pixel existing at the block boundary position on the basis of the block noise feature information. The image processor can be applied, for example, to an image processor such as a television receiver. <P>COPYRIGHT: (C)2009,JPO&INPIT |
