Abstract:
Image data on a color image can be converted into image data representing a vivid sketchy image with no manual operation. An original image (1) which is image data represented by a three primary color expression using RGB is inputted into first color conversion means (2), which converts the original image (1) into a brightness component and a chromaticity component in a color space in which the chromaticity does not vary or hardly varies even if the brightness varies. Filtering means (4) carries out a space filtering of the brightness acquired by the conversion by the first color conversion means (2). Second color conversion means (5) carries out deconversion of the first color conversion means (2) by using the chromaticity acquired by the conversion by the first color conversion means (2) and the space filtering results.
