Title:
IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/035732
Kind Code:
A1
Abstract:
Provided are an image processing apparatus and an image processing method by which the coding efficiency can be increased in the intratemplate matching system when there is variation in brightness with respect to the same texture in a screen.
An intratemplate matching unit (75) performs matching on a block of images in a frame to be coded in the intratemplate matching system and performs weighted prediction. A reversible coding unit (66) inserts template system information indicating whether the weighted prediction has been performed or not into the header portion of a compressed image. The present invention can be applied, for example, to an image coding apparatus which performs coding in the H.264/AVC system.
