Abstract
A method, system and device for enhancing detail in areas of saturated color in an image are described. As areas of saturated color are detected in an image the opponent color channel is used to calculate a factor to apply to the original pixel value. By calculating this factor to adjust the pixel values of the image detail may be enhanced in the color saturated areas. A user supplied value may also be included to control the amount of automatic adjustment to the pixel values.
Claims2
A method of image processing comprising:
- determining an area of saturated color in an input image;
- identifying the opponent color of the saturated color at this location of the input image;
- calculating an interpolant factor to apply when combining a processed color image and a luminance image;
- and
- applying this interpolant factor to each appropriate location of a combination of the two input images to produce an output image result.
