ABSTRACT:
An image amending method for amending a signal indicative of an image which was photoelectrically converted comprises: classifying pixels which constitute a digital image into extraordinary pixels which need to be amended and ordinary pixels which do not need to be amended; setting an attention pixel; when the attention pixel is an extraordinary pixel, amending the data thereof by setting data of a peripheral ordinary pixel (other than pixels adjacent at the positions adjacent to the attention pixel in the upper, lower, left, and right directions) as amendment data for the extraordinary attention pixel; and, preferably, limiting a range of the peripheral pixels which are substituted for the extraordinary attention pixel. When no ordinary pixel exists in this range, in the amending step, the data of a previously amended peripheral pixel is set as the data of the attention pixel. With this method, a person without much experience can easily satisfactorily amend the image.
