ABSTRACT:
An image signal restoring device is arranged to input a digital image signal, to output a digital image signal which has been delayed for a first period of time when the input digital image signal is delayed for the first period of time, and to output a digital image signal obtained by adding together the input digital image signal and a digital image signal which has been delayed for a second period of time when the input digital image is delayed for the second period of time. The arrangement enables the device to stably restore the image signal without any adjustment, etc.
