Title:
VIDEO IMAGE ENCODING DEVICE, VIDEO IMAGE DECODING DEVICE, VIDEO IMAGE ENCODING METHOD, VIDEO IMAGE DECODING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/063440
Kind Code:
A1
Abstract:
A video image encoding device includes an adaptive color-difference quantization offset derivation unit capable of selecting the color space of a prediction error signal in encoding block units from a plurality of color spaces and deriving the quantization offset for each color space, and a dequantization unit for dequantizing a quantization coefficient image using the color-difference quantization offset for each color space.
