Raw input is companding data in 12bit.
Because PWL module only support 4 segments, we try to increase points by merge pwl-curve into decompanding-lut which support to 639 points.
Below is the settintg we used:
- PWL curve use a linear curve shift to 24bit. X1~X3 is 1024 2048 3072, mask is 405, Y1~Y3 is 4194304 8388608 12582912, slope is 4096.
- Decompanding-lut is 24bit to16bit, which merging de-pwl curve of 12bit to 24bit.
Is the above method feasible in your opinion? And whether the above parameters are unreasonable?
We tested the method and found the result of VISS existing brightness saturation.
