Abstract

A prediction value is previously set in an MPS table corresponding to a state number, a state number for an encoding pixel is obtained from a STATE table, the prediction value is determined based on the MPS table using the state number, a pixel-to-symbol converter compares the prediction value and the encoding pixel to obtain a symbol, and an arithmetic encoder obtains an LPS interval from an LSZ table using the state number for the encoding pixel, and the arithmetic encoder implements encoding based on the symbol and the LPS interval.
