Abstract:
An image signal processor comprising:an encoded image signal pickup means which encodes an image on the basis of a unit as defined by dividing the image spatially and/or on a time series basis and picks up one or a plurality of encoded image signals;an object specifying means which specifies the objective encoded image signals contained in a unit selected as an object of image transform processing from the encoded image signals picked up by said encoded image signal pickup means;a local decoding means which locally decodes only the encoded image signals specified by said object specifying means;a processing means which performs predetermined processing of the image signals decoded by said local decoding means;a local encoding means which locally encodes the image signals processed by said processing means; anda composing means which composes the encoded image signals encoded by said local encoding means and the original encoded signals contained in units other than the objective unit.
