Camera board • Re: Switching HDR and non-HDR for Camera Module 3 in kernel driver

Although I set the analog gain to 16.0, the footage seems dimmer using mode_hdr_regs with HDR disabled via register, compared to using mode_2x2binned_regs. Any reasons behind this? Thanks.
Ah yes. We do Auto-Exposure differently in HDR mode, based on a pre-Tonemap histogram from the camera. One of those register settings will enable/disable sending the histogram, disabling it should make things behave more normally. I don't have the details to hand, but will check some time next week.

There may be other reasons -- HDR has been "nobbled" but it might still be trying to do something. The trick will be to identify the smallest change that produces an acceptable picture without stopping the stream or glitching too badly.
