ABSTRACT:
An image processing method, comprises: an input step of inputting a color digital image; a white balance correction step of correcting white balance of the inputted digital image; an exposure correction step of correcting exposure of the digital image having the corrected white balance; a determination step of determining a pixel in which an output pixel value is saturated without being corrected to be underexposed by the exposure correction, among respective pixels in the digital image having the corrected white balance; and a pixel value correction step of setting only the determined pixel to be saturated as a correction target pixel and correcting the pixel value of the correction target pixel to be more than or equal to the pixel value. Thereby, the color attachment with respect to the blown-out highlight portion can be prevented at the time of the desensitization process.
