Error concealment of an erroneous pixel in a line of pixels is provided by adaptively using a large number of adjacent correct pixels along the same horizontal line. The invention discards any corrupted adjacent pixel which would be used in the calculation for a replacement pixel value, while modifying the weighting of the remaining adjacent correct pixels in accordance with the error pattern generated by the corrupted pixel or pixels. An overflow detection circuit also is included, which provides an acceptable replacement pixel value rather than using the unacceptable overflow value.
