MOVING IMAGE RECODING UNIT, MOVING IMAGE CODING METHOD, AND MOVING IMAGE RECODING PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent deterioration of image quality and to reduce processing time, when recoding a coded data in which deblock filtering is performed.;SOLUTION: A decoder 100 decodes the coded data in which deblock filtering is performed, and outputs a pre-deblock filtered decoded image and a post-deblock filtered decoded image to a decoded image switch 200. In case of deciding to perform deblock filtering at the time of recoding based on a recoding system signal, a docoded image switch 200 outputs the pre-deblock filtered decoded image to a recoder 300, while in case of not performing the deblock filtering at the time of recoding, the docoded image switch 200 outputs the post-deblock filtered decoded image to the recoder 300. The recoder 300 performs recoding after deblocking only when the pre-deblock filtered decoded image is input.;COPYRIGHT: (C)2007,JPO&INPIT
