Color imaging system and process with high-speed rendering

A system for processing images, based on using a cube with a plurality of sub-cube portions to transform source color image values to target color image values, the system comprising:

• an image file subsystem providing at least one source color image value represent a source color comprising;
• a color transformation subsystem operatively coupled to the image file subsystem and accepting as input the at least one source color image value and producing at least one target color image value therefrom;
• and
• an image forming subsystem operatively coupled to the color transformation subsystem and forming a physical manifestation of the source color image from the produced at least one target color image value, the color transformation subsystem being configured to
• define a memory area for at least one sub-cube portion as representative of the at least one source color image value;
• determine target color values corresponding to the defined sub-cube portion to populate the memory area;
• determine the at least one target color image value in response to the determined target color valurs;
• and
• determine the at least one target color image value in a first manner in response to an accuracy of interpolation exceeding a predetermined threshold and to determine the at least one target color image value in a second manner in response to the accuracy of interpolation not exceeding a predetermined threshold;
• such that the at least one target color image value can be determined without the need of determining all of the target color values corresponding to all of the sub-cube portions.
