Abstract

본 발명은, 동화상 데이타 복호화 장치에 있어서, 부호 착오를 정정할 수 없는 전송 에러가 생긴 경우에도, 화상의 홈결 부분을 주변 화상에 대해 미끄럽게 수정할 수가 있다.According to the present invention, even in the case of a transmission error in which a code error cannot be corrected in the moving picture data decoding apparatus, the grooved portion of the picture can be smoothly corrected with respect to the surrounding picture.

정정할 수 없는 부호 착오가 생긴 블럭을 과거의 프레임 화상에 의거해서 정해지는 과거의 움직임 벡터에 의해 생성되는 블럭 화상으로 바꾸어 놓아서 복호하므로서, 복호화상의 움직임의 유무에 관계없이, 부호 착오에 의한 화상의 홈결 성분을 주변 화상에 대해서 미끄럽게 수정할 수가 있다.By decoding a block in which a code error that cannot be corrected is replaced with a block image generated by a past motion vector determined based on a past frame image, the image due to a code error can be decoded regardless of whether there is a motion in decoding. The gutter component can be slipperyly corrected with respect to the surrounding image.
