Abstract:
An image processing method comprising the steps of:i) carrying out a morphology operation on an 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 a characteristics output with respect to at least one of:an image portion, at which said original image signal Sorg fluctuates in a spatially narrower range than said structure element Bi, andan image portion, at which a change in said original image signal Sorg is sharp,ii) dividing said original image signal Sorg into frequency components S.sub.n falling within a plurality of different frequency bands, andiii) for each of said plurality of different frequency bands, carrying out image emphasis processing on the frequency components S.sub.n using emphasis coefficients that are different for each of the frequency bands and in accordance with the morphology signal Smor so as to produce a processed image signal Sproc.
