PROBLEM TO BE SOLVED: To enable smoothing selectively changing edge enhancement or strength while considering all band components contained in edges by performing band division processing and performing band synthesis processing after reloading band components while referring to the band components. SOLUTION: In a band dividing step 101, an image to be the object of processing is inputted and such images are divided into plural bands. In a band component change step 102, while referring to one or plural band components, one or plural band components are reloaded. In an image synthesizing step 103, the divided and changed band components are synthesized, made into image and outputted. In this case, the band component of a visually important edge is widely distributed from low frequency component to high frequency component but the band component of visually non-important edge or noise is eccentric in the high frequency component of its strength. Then, in the band dividing step 101, band division is performed while using wavelet transformation. |
