Abstract
An image signal processing apparatus features image signals which are compressed, then stored and expanded to regenerate the original image. The compression and expansion are effected in a ratio determined in consideration of the available memory capacity, so that the signals of an image of a given size can always be stored in a memory of a given capacity, regardless of the content of the image. Also an efficient compression can be achieved by replacing the sequence of image signals.
