Surface Size

The LUT structure is defined by Channel parameters LUT_InDataWidth and LUT_OutDataWidth.

Following table shows the values of both parameters:

Note: GRABLINK Quickpack CFA implements high-dynamic LUT's!

With the Advanced LUT API, each entry in a LUT surface plane is 32-bit wide; independently of the LUT_OutDataWidth.

With the Classic API, an entry in a LUT surface plane is 8-bit when LUT_OutDataWidth = 8 and 16-bit when LUT_OutDataWidth = 10.

Following table list the SurfaceSize requirement for each plane of the LUT Surface as a function of LUT_InDataWidth, LUT_OutDataWidth for both the Classic and Advanced LUT API's.
