VIDEO IMAGE ENCODING DEVICE AND VIDEO IMAGE DECODING DEVICE

摘要

A video encoding device and a video decoding device prevent an increase in the number of lines of a reference line buffer in a pseudo random noise injection process. The video encoding device includes: an inverse quantization unit for inverse-quantizing a quantization index to obtain a quantization representative value; an inverse frequency transform unit for inverse-transforming the quantization representative value obtained by the inverse quantization unit, to obtain a reconstructed image block; and an asymmetrical distortion removal filter unit for injecting pseudo random noise to an area asymmetrical about a boundary of the reconstructed image block.
