White balance gain and colour correction matrix
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Per-channel white balance gains followed by a 3x3 colour correction matrix with offsets.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
