Abstract
A predictive coding system performs predictive encoding by determination of an optimum prediction mode from prediction methods for a pixel signal of a target block. A predicted signal is generated according to the determined mode, and a residual signal is determined. The residual signal and the optimum prediction mode are encoded to generate a compressed signal, which is decoded. The decoded signal is stored as a reconstructed picture sample. During encoding, a candidate prediction mode list is generated that contains elements of optimum prediction modes of previously-reproduced blocks neighboring the target block. A flag indicating whether the list contains an element corresponding to the optimum prediction mode is encoded, and an index to the corresponding element is encoded if the corresponding element is included in the list. The optimum prediction mode can be encoded based on identifying the elements in the list, unless no corresponding element appears on the list.
