Abstract
The subject application is directed to a system and method for color space conversion. Image data is received comprised of a plurality of pixels having a value encoded in a first multidimensional color space. Each of the pixels encoded in the first color space is converted to a corresponding pixel encoded in a second multidimensional color space, the conversion further including transforming each of the pixels based upon a function of the pixel values in the first color space having component values defining a fractional relationship having a numerator portion and a denominator portion, with each portion including at least one of the component values. A value of each denominator portion is converted relative to a threshold value and the pixels encoded in the first color space are converted to the second color space with an alternative quantity selectively substituted for each denominator portion in accordance with the comparison.
