I have a Raspberry Pi NoIR V2.1 camera. I am working with the NIR (940 nm) LEDs and I saw that I was getting funny/weird colors, so I assumed that it is due to the white balancing, so I switched off the auto white balancing (
awb_mode = 'off') and set the gains to
1, 1 (
awb_gains = 1, 1).
I believe my camera's white balancing is off now, however, I noticed that I am getting a weird split in the top half of the image. I noticed this phenomena in all images when awb is
off and gains manually set to
1,1, while this does not appear when taking regular photos with white balancing on. Is there any explanation why is it happening? Has anyone encountered the same issue? Picture below shows output from the camera.
P.S. I checked with two NoIR V2.1 cameras that I have and both of them produce the same result, so it must be software based problem.
