When it is determined that a film original is at least one of an under-exposed negative film and a high sensitive film, the image processing method and apparatus separate the input image signals into at least three kinds of frequency components composed of lowest frequency components a band of which is made more narrower, frequency components containing high frequency components and at least one kind of remaining frequency components, enhance frequency components containing the high frequency components, suppress at least one kind of frequency components of the remaining frequency components and synthesize both of enhanced and suppressed frequency components and the lowest frequency components. The method and apparatus are capable of obtaining a reproduced image having good image quality by suppressing graininess and further improving the reproduced image particularly in the under-exposed negative film and the high sensitive negative.
