Title: Image processing unit, image processing method, and medium recording image processing program
Inventor: KUWATA NAOKI
IPC: G06T5/00
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To attain proper processing by automatically discriminating a type of image data. SOLUTION: Distribution of luminance as to each picture element selected by applying interleave processing to image data is summed (step S102) to count number of colors in use (step S104). As a result, when number of colors in use is many, it is discriminated that a kind of the image data indicates a natural image. Based on the discrimination result as above, this method is applied to a natural image so as to select automatically a proper contrast magnification processing (step S110), a saturation emphasis processing (step S112) and an edge emphasis processing (S114).  Moreover, in the case of a natural image, color conversion by a preliminary gradation conversion is conducted in the print processing, and in the case of images other than a natural image, color conversion adopting cache + interpolation arithmetic operation is conducted, and then the color conversion processing with small processing amount is automatically selected.
