- Gain map is MxN down-sampled, M being the horizontal sampling factor, N being the vertical sampling factor, M and N being {8,16,32.64,128 } independently.
- The size of the internal memory is based on a 2Mpix sensor with 16x32 downscaling ratio. As such the size is approximately 19 Kbytes-( 4758 locations with 4 Bytes/location) -> Each entry has gains for all 4 colors. This corresponds to a sensor resolution of 1928 x 1208
- Support 8-bit entry in the gain map (in U8Q8, U8Q7, U8Q6, and U8Q5 format with optional base of 1.0 to shift the range up)
Figure 6-70 illustrates the LSC active region and map up-scaling feature. (The maps are stored independently per color channel)
