PROBLEM TO BE SOLVED: To apply image processing to digital image data so that an image with a preferable saturation can be reproduced. SOLUTION: A color conversion means 6 of an image processing means 2 applies color conversion processing to image data S0 obtained by a digital camera 1. The color conversion means 6 obtains a Lab, a metric chroma value and a hue angle of each pixel from the image data S0. The chroma value is weighted based on the chroma value, a lightness L' and the hue angle HA. A weighting coefficient is selected 50 that a saturation of a desired pixel is more emphasized than a saturation of other pixels. Processed image RGB data S1 are obtained through the application of reverse operation to the weighted chroma value, the lightness and the hue angle.
