Abstract:
An image signal processing apparatus for processing an image signal comprised of plural blocks, comprising:reproducing means for reproducing, from a recording medium, an encoded image signal which includes the image signal and an error correction check code;error correction means for detecting correctable and uncorrectable errors in the encoded image signal reproduced by said reproducing means, and for correcting correctable errors, by error correction processing the reproduced encoded image signal, where each of the correctable and uncorrectable errors is a code error that arose after the image signal was encoded;motion vector detection means for detecting a motion vector of an error block which includes an uncorrectable error, by using the image signal reproduced by said reproducing means; andimage signal forming means for forming a replacement image signal for the image signal of the error block, the replacement image signal being formed based on the motion vector for the error block detected by said motion vector detection means.
