Abstract
A method for a fast color saturation control of digital color images using one color saturation factor has been achieved. Said method can be performed in any color space having three primaries as e.g. the R-G-B or in the CMY color space without the requirement to convert all the pixels of said color image into another color space as e.g. HSI to perform the color saturation control. Thus a significant computational effort for the conversion of the pixels from one color space into another and back can be avoided. Saving computational effort saves time and reduces the electrical power consumption. Right after the color saturation control process the corrected images can be viewed, if the colors are not satisfactory the process can be easily repeated using a modified color saturation factor. Said method can be used for new pictures taken by a digital camera as well as for downloaded pictures from any source. Additionally said method of color saturation control can be combined with a color correction process.
