ABSTRACT:
The disclosed is to provide an image signal processor and its method in which the enhancement of resolution and the effective reduction of noise are compatible. The image signal processor is provided with an edge character detector that detects a character of an edge of an object, an image signal frequency zone limiter that executes a noise removing process, an image signal frequency zone enhancer that executes a resolution enhancing process and a gain controller that changes each intensity of the image signal frequency zone limiter and the image signal frequency zone enhancer according to an output result of the edge character detector.
