  • Patent number: 5739922
    Abstract: In an image processing method for carrying out processing on an image signal, which represents a given image, the image signal is separated into low frequency components, middle frequency components, and high frequency components. Emphasis and restriction processing is carried out, with which the high frequency components are emphasized and the middle frequency components are restricted. The high frequency components and the middle frequency components, which have been obtained from the emphasis and restriction processing, and the low frequency components are combined with one another, and a processed image signal is thereby obtained. The image sharpness is thus emphasized, and noise components due to film graininess are removed, such that a reproduced image having good image quality may be obtained.
