Patent ID: 7430061

Claim:
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 x of the image data is represented by a value P x =(C 1x , C 2x , . . . , C nx ), wherein each received image pixels P x , is in a selected value range; reflectance space conversion means adapted for converting received image data P x , to input reflectance space data comprised of corresponding values in reflectance space; density space conversion means, including means adapted for logarithmically converting input reflectance space data so as to be represented by corresponding values R x in a density space; saturation correction means adapted for generating saturation corrected values R′ x by application of a masking equation corresponding to each value R x ; the density space conversion means further including antilog conversion means adapted for converting the saturation corrected values R′ x from the density space to output reflectance space data comprised of corresponding values thereto: means adapted for converting output reflectance space data to the n-dimensional color space C as corresponding saturation corrected pixel values P′ x ; and means adapted for outputting the saturation corrected pixel values P′ x , as a saturation corrected image data set output.
