PROBLEM TO BE SOLVED: To efficiently emphasizes only a specific image part of interest without emphasizing any component which is not necessary for an image read such as a noise component of an image. SOLUTION: For image data S as a set of density values Dorg of high density and high signal level stored in an entire image memory 10, morphology operation shown by the equation is performed by a morphology filter (abnormal shade detecting means) 40 by using a multiple structure element Bi and a scale coefficient λ to detect a signal value Dmor showing a fine limed shade, and for this signal value Dmor, operation of Dproc=Dorg+α.f(Dmor) (where αis an emphasis coefficient and f(Dmor) is a function of Dmor) is performed by a local image emphasizing means 70 to selectively emphasize only the fine calcified shade, so that the shade is displayed on a local image display means 90. |
