<p>A method and an apparatus for concealing an error are provided to perform the error concealing work for each frame effectively when the loss of frame occurs in an apparatus for receiving and outputting a compressed moving image. A reference direction of a loss frame is determined through switching of the scene between frames based on the loss frame(S408). Concealing reference points for pixels constituting the loss frame are extracted by using one or more frames except the loss frame according to the determined reference direction(S410,S412,S414). Concealing pixel values for the pixels constituting the loss frame are obtained by providing the weights to the extracted concealing reference points(S411,S413,S415). The loss frame is restored by performing the concealing process for the pixels using the obtained concealing pixel values(S416).</p> |
