Abstract:
1. A system for dynamic color saturation adjustment comprising: means adapted for receiving an image data set formed from pixel values P encoded in an n-dimensional color space C, wherein n is an integer greater than one, such that each pixel P reflectance space conversion means adapted for converting received image data P density space conversion means, including means adapted for logarithmically converting input reflectance space data so as to be represented by corresponding values R saturation correction means adapted for generating saturation corrected values R′ the density space conversion means further including antilog conversion means adapted for converting the saturation corrected values R′ means adapted for converting output reflectance space data to the n-dimensional color space C as corresponding saturation corrected pixel values P′ means adapted for outputting the saturation corrected pixel values P′
