<p>A signal-processing system comprising an estimating unit (5) for estimating an amount of noise or a scene as a characteristic amount from an image signal captured by CCD (2) and provided by a preprocessing unit (3) in digital form, an edge-extracting unit (6) for extracting an edge component of an image associated with the image signal, a correction-coefficient calculating unit (7) for calculating a correction coefficient for correcting the edge component on the basis of the characteristic amount and the edge component, and an edge-enhancing unit (8) for performing edge enhancement with respect to the image signal on the basis of the edge component and the correction coefficient.</p> |
