Abstract
The invention provides an image signal processing apparatus for processing an image signal. When an image signal is supplied and the input image signal is stored onto a memory medium and the image signal stored on the memory medium is generated, only the image signal generated from the memory medium in the image signal stored on the memory medium can be erased, so that the image signal can be stored by a simple construction without erroneously erasing the image signal stored on the memory medium.
