ABSTRACT:
In a coding system, when any of the prediction results of pixel value prediction sections 20 and 21 matches an object pixel, a coding section 50 codes an identifier of the pixel value prediction section whose prediction result matches the object pixel. When none of the results match the object pixel, the coding section 50 codes a prediction error of a prediction error calculation section 30. A decoding system decodes code to an identifier or prediction error and outputs pixel data from the corresponding pixel value prediction section based on the identifier or takes out pixel data from a prediction error addition section 31 based on the predication error.
