ABSTRACT:
An image signal processing system includes an encoding apparatus having a data compressing circuit for compressing input image data and a recording unit for recording compressed image data from the data compressing circuit on a magnetic tape, and a decoding apparatus having a data expanding circuit for decoding the compressed image data recorded on the magnetic tape to restore original image data. A distortion suppressing circuit is connected in a stage following the data expanding circuit for adaptively band-limiting the restored image data based on motion vector data detected in a motion compensation process, detected vector information, and editing information detected by a detecting circuit in a recording decoder in the data expanding circuit.
