Abstract
If an error is detected during the decoding of motion image data a portion of the image is lost and image quality deteriorates even after correction. When motion compensation prediction is used the image quality of subsequent pictures can also be adversely affected. This apparatus has a bit stream analysis portion for analyzing each macro block of a moving image, a contaminated region registering portion for registering a region as a contaminated region if an error has been detected during analysis, a motion vector selection portion for determining a predicted image to be used for motion compensation prediction, a contaminated region judging portion for judging whether or not a predicted image is contaminated and a loop filter portion for filtering a predicted image which is contaminated, so that it is smoother for decoding.
