System and method for mapped splicing of a three-dimensional look-up table for image format conversion

A system for mapped splicing of a three-dimensional look-up table (“3D LUT”) to minimize memory consumption for converting image data, the system comprising:

• a 3D LUT splicer configured to splice an initial 3D LUT into a plurality of sub-cube vertices that are stored on a plurality of separate electronic memories, respectively, wherein the initial 3D LUT comprises red, green and blue (“RGB”) color components for converting the image data;
• an index value identifier configured to identify the plurality of sub-cube vertices corresponding to at least one pixel to be converted based on a set of index values for the RGB color components of the at least one pixel;
• a plurality of address translators configured to determine memory access addresses for accessing respective RGB color components to convert the at least one pixel based on each of the identified plurality of sub-cube vertices of the at least one pixel;
• and
• an image data output configured to access the respective RGB color components in the plurality of separate electronic memories based on the determined memory access addresses and convert the accessed RGB color components to image data configured to be displayed on a content consuming device in a converted image format.
