Document Type and Number:
Japanese Patent JP4697557
Kind Code:
B2
Abstract:
An encoding device includes: a color-difference signal encoding unit for encoding a color-difference signal for each processing block in multiple color-difference signal encoding modes to generate multiple color-difference signal bit streams; a color-difference mode selecting unit for selecting a color-difference signal encoding mode from the multiple color-difference signal encoding modes; a luminance signal encoding unit for calculating luminance target code amount by subtracting the code amount of the encoded color-difference signal bit stream from fixed code amount, and encoding a luminance signal to generate a luminance signal bit stream; a color-difference reselecting unit for selecting the color-difference signal encoding mode corresponding to the color-difference signal bit stream having the code amount not greater than the fixed code amount, and small deterioration as to the color-difference signal; and a multiplexing unit for multiplexing the luminance signal bit stream, and the encoded color-difference signal bit stream to generate a bit stream.
