Abstract
An image processing method for carrying out predetermined correction processing with respect to one or more items regarding the quality of color images and the image processing method comprises a judgment step for judging the necessity/nonnecessity of correction with respect to each of the above-mentioned items and a correction processing step for carrying out the predetermined correction processing with respect to the item judged as required to be corrected at the above-mentioned judgment step.
Claims6
A judging method of sunset scene, comprising:
- converting, by an apparatus, color components R, G and B of an image data into hue data, lightness data and saturation data;
- calculating, by an apparatus, first products of the hue data and the saturation data of the pixel of red and yellow in the image data;
- calculating, by an apparatus, second products of the hue data and the lightness data of the pixel of red and yellow in the image data;
- and
- judging, by an apparatus, whether the image data is the sunset scene based on first and second products.
An image processing apparatus, comprising:
- a memory which stores an image data of a color image;
- a judge section which judges whether correction of the color image based on a quality of sunset scene,
- wherein the judge section comprises;
- a unit for calculating first products of the hue data and the saturation data of the pixel of red and yellow in the image data;
- a unit for calculating second products of the hue data and the lightness data of the pixel of red and yellow in the image data;
- and
- a unit for judging whether the image data is the sunset scene based on first and second products.
A non-transitory computer readable medium with a recorded program, the program, upon being executed, performing:
- converting color components R, G and B of an image data into hue data, lightness data and saturation data;
- calculating first products of the hue data and the saturation data of the pixel of red and yellow in the image data;
- calculating second products of the hue data and the lightness data of the pixel of red and yellow in the image data;
- and
- judging whether the image data is the sunset scene based on first and second products.
