Inverse conversion A method for decoding a moving image that performs dynamic range conversion reduced by shift memory.

摘要

PROBLEM TO BE SOLVED: To reduce a dynamic range of image decoding. A method of decoding a moving image includes a step of receiving a quantization coefficient indicating a block of the moving image representing a plurality of pixels. The quantization coefficient is inversely quantized based on the function of the remainder. The dequantized coefficients are inversely transformed to obtain the decoded residuals.
