Abstract:
1. A method of converting from a first color space to a second color space using a processor, comprising: receiving first component values related to said first color space on the processor, wherein said first component values are red, blue and green component values; evaluating, by the processor, said first component values to determine if they represent well-defined component values in at least one of said first color space and said second color space, wherein said well-defined component values comprise hue, saturation and brightness values; converting, by the processor, from said first color space to said second color space to determine second component values related to said second color space; caching said well-defined component values in a cache; determining, by the processor, if said red, blue and green values are equal; and if not, calculating, by the processor, said hue, saturation and brightness values from said red, blue and green values; and updating said cache with the calculated hue, saturation and brightness values.
