Patent ID: 6919924

Claim:
An image processing method of creating output image data for obtaining a reproduced image by executing image processing on digital image data obtained by a digital camera, comprising: a step of determining at first a density conversion condition for an image expressed by the digital image data, the density conversion condition being a first conversion function for density correction between the digital image data and the output image data to increase or decrease a density of a whole image; a step of determining next a gradation conversion condition for the image expressed by the digital image data on the basis of the density conversion condition, the gradation conversion condition being a second conversion function for the density correction and gradation correction between the digital image data and the output image data to control gradations in a predetermined range of the density of the image; and a step of modifying the digital image data on the basis of the density conversion condition and the gradation conversion condition, thereby creating the output image data for obtaining the reproduced image, wherein a predetermined value is inputted and the gradation conversion condition is so determined as to harden or soften a tone of the image expressed by the digital image data based on the predetermined value.
