摘要 |
A blurred image generating section generates a plurality of blurred images Sm (where m=1 to n and n>=2) different in frequency response characteristic from one another, based on an original image S 0 . A band-limited image generating section generates a plurality of band-limited images Tm by performing a subtraction between images of adjacent frequency bands, employing the original image S 0 and each of the blurred images Sm. A wrinkle component extraction section extracts converted images, obtained by performing nonlinear conversion on each of the band-limited images Tm, as wrinkle components Qm contained in the different frequency bands. A wrinkle-component elimination section eliminates wrinkle components of the original image S 0 by subtracting from the original image S 0 a value obtained by multiplying a subtraction coefficient beta (which is determined according to the pixel value Y 0 of the original image S 0 ) and the sum of the wrinkle components Qm together. |
