Abstract:
1. A color space conversion system, including a processor which is configured to execute instructions which cause the processor to operate the system, the system comprising: an input operable to receive image data comprised of a plurality of pixels having a value encoded in a first multidimensional color space; a color space convertor operable to transform each of the plurality of pixels encoded in the first multidimensional color space to a corresponding pixel encoded in a second multidimensional color space, the color space convertor further being operable to transform each of the plurality of pixels in accordance with a function of the pixel values in the first multidimensional color space having component values thereof defining a fractional relationship having a numerator portion and a denominator portion, each of which portions include at least one of the component values; a comparator operable to compare a value of each denominator portion relative to a threshold value; and the color space convertor further being operable to transform each of the plurality of pixels encoded in the first multidimensional color space to the second multidimensional color space with selective substitution of each denominator portion with an alternative quantity in accordance with an output of the comparator.
