WIPO Patent Application WO/2012/090454

A1

Provided is a video encoding device comprising: a planar prediction unit that uses planar prediction; and a noise mix-in unit that mixes pseudo-random noise into a prediction image in a planar prediction block, when a reconstruction prediction error value for planar prediction falls below a threshold value determined by planar prediction block size. The video encoding device then suppresses gradient distortion by using pseudo-random noise for linear interpolation for calculating the prediction image, based on conditions generated by gradient distortion.
