摘要：
The present invention provides an image signal reproducing apparatus, in which code errors are concealed by using only pixel data corresponding to parts of the pixels of respective two or more adjacent blocks both of which are adjacent to a subject block to be concealed in the same frame, to conceal the code errors without disturbing the image even if the image is rapidly moving and all of pixels included in the block are not available.
