<P>PROBLEM TO BE SOLVED: To remove noise according to images and/or bit rate. <P>SOLUTION: A low-pass filter setting section 93 sets a filter coefficient corresponding to intra-prediction mode information and quantization parameters from among filter coefficients stored in an internal filter coefficient memory 94. An adjacent pixel setting section 81 uses the filter coefficient set by the low-pass filter setting section 93 to perform filter processing on adjacent pixel values of a target block from a frame memory 72. A predictive image generation section 82 uses the adjacent pixel values subjected to the filter processing from the adjacent pixel setting section 81 to perform intra-prediction, and generates a predictive image. For example, the present invention can be applied to an image coding apparatus for coding in an H.264/AVC system. <P>COPYRIGHT: (C)2013,JPO&INPIT |
