RGB-IR IMAGE SIGNAL PROCESSOR
Our high-quality RGBW processor has been adapted for use with RGB-IR and can be easily modified for any 3 or 4 color CFA. This processor provides the same excellent demosaicking quality required for mobile phone applications to RGB-IR.
In order to compensate for crosstalk between RGB and IR, it is necessary to have high-quality reconstruction of both color planes. If the quality of either plane is poor, the quality of both will be adversely affected after color correction.
It is also essential to clean up noisy color planes with clean ones, since RGB and IR can be illuminated very differently. This is similar to how RGBW uses the high SNR W color plane to clean up RGB. Our ISP is capable of delivering clean RGB even in night scenes illuminated by IR LEDs.
