ABSTRACT:
A method for compressing and extending image signals, which represent a plurality of images obtained by the recording of a set of images wherein the images of a single object are recorded simultaneously or sequentially, comprises the steps of carrying out inter-image operation processing on the image signals representing the plurality of the images, and carrying out signal compression processing on image signals, which have been obtained from the inter-image operation processing. In the course of reproducing the images, signal extension processing is carried out on image signals, which have been obtained from the signal compression processing. Reversed inter-image operation processing, which corresponds to the reversed operation of the inter-image operation processing, is then carried out on image signals, which have been obtained from the signal extension processing. Image signals corresponding to the images are thereby obtained.
