PURPOSE: To simultaneously realize the elimination of an impulse noise and the restoration of blurring by changing an image signal to be outputted as necessary. CONSTITUTION: An image processor is composed of a storage circuit 1 storing an image signal, a decision circuit 2 deciding the necessary/unnecessary of the correction of an image and an address circuit 3 designating the address of a picture element signal to be outputted in accordance with the decision result. In the decision circuit 2, noise and a blurred part are recognized, the picture element signal of this part is not outputted as it is, the signal is changed by the most approximate correction unnecessary picture element signal and the signal is outputted. As a result, noise can be eliminated, and at the same time, the contour of a graphic can be made conspicuous. |
