Abstract:
An image processing method comprising the steps of:i) carrying out a morphology operation on an original image signal Sorg, which represents an image, by using a structure element Bi and a scale factor .lambda., a morphology signal Smor being thereby obtained, said morphology signal Smor representing whether each of picture elements constituting said image is or is not the one corresponding to one of: an image portion, at which said original image signal Sorg fluctuates in a spatially narrower range than said structure element Bi, and an image portion, at which a change in said original image signal Sorg is sharp,ii) carrying out first image emphasis processing on said original image signal Sorg and in accordance with said morphology signal Smor such that said image portion may be emphasized, a first processed image signal S' being thereby obtained, andiii) carrying out second image emphasis processing on said first processed image signal S' and in accordance with said first processed image signal S' such that an image portion, which corresponds to only a desired frequency band among the frequency bands of said first processed image signal S', may be emphasized.
