  • System and method for mapped splicing of a three-dimensional look-up table for image format conversion
    Patent number: 11094035
    Abstract: A system and method that splices an initial 3D LUT for imaging format conversion into a plurality of smaller LUTs that can be stored in separate RAMs. During operation, the upper 5-bits serve as index values of each component of an incoming GBR pixel and are used to determine which of the smaller RAMs contain the correct index values for the pixel data. Specifically, a first index value can be derived from the incoming GBR pixel data and used to lookup all sub-cube vertices corresponding to the incoming pixel and the corresponding RAMs. After determining the correct RAMs, a predetermined algorithm for each given RAM is applied to find the normalized RAM look-up addresses and identify the correct data for the exemplary imaging format conversion process.
