COMPUTER-READABLE ENCODERS, DECODERS, AND RECORDING MATERIALS ARE NOT TEMPORARY.

Abstract

The invention relates to a set of encoders (100) comprising a circuit and a memory coupled to the circuit. When operating, the circuit performs a deterministic processing to determine the edge intensity to control the decondensing filter applied to the edge of the generated image (S311). The deterministic processing includes a setting process to set the edge intensity to a second value in the case where one of the encoding modes of the current block and the encoding mode of the adjacent block of the current block differs from another of the encoding modes of the current block and the encoding mode of the adjacent block. One encoding mode and another encoding mode are the modes of the internal block copying mode, the color mode, and the associated mode. The setting process is performed when the current block is a luminance block and is not performed when the current block is a chroma block.
