Abstract

There is provided an image reproducing apparatus comprising a reproducing circuit for reproducing an image signal which was divided into blocks and encoded from a recording medium, a decoding circuit for decoding the image signal reproduced by the reproducing circuit, a movement detection circuit for respectively detecting and outputting movements of a plurality of blocks around a block including the image signal which cannot be decoded by the decoding circuit, and a constructing means for constructing an image signal for a block including the undecodable image signal, wherein a precision of a movement estimation of the undecodable image signal can be raised and an image which is hardly visually deteriorated can be obtained.
