Abstract
A motion image decoding apparatus receives encoded image data which has first, second and third data regions, such as MPEG macroblocks which have predetermined sizes, and a motion vector for each of the data regions. The motion image decoding apparatus conceals errors in the first data region by generating an error signal and using a motion vector of a second data region which is located on a line preceding a line containing the first data region having the error and which is in a same picture as the first data region and also by using a motion vector corresponding to a third data region which is located in a column preceding the column containing the first data region having the error and which is also in a same picture as that of the first data region. If no error is generated in the first data region, the motion vector for that data region is used to perform motion compensation.
