Camarray – Arducam 1MP (OV9782 Color) Quad-Camera Bundle Kit

  1. What hardware/platform were you working on?

Jetson Nano

  1. Instructions you have followed. (link/manual/etc.)
  1. Problems you were having?

The brightness of the video in general, but also between the individual cameras varies a lot. These are two images I took outside (left) and from inside (right) on a cloudy day with the exposure set to the default value 681.

I changed the standard lenses of the first and the second camera to Arducam 1/4" M12 Mount 3.2mm Focal Length Low Distortion Camera Lens M40320M06S

I recall having exactly the opposite problem when I first connected the Camarray to my Jetson Nano. On a cloudy day the video was very dark. I have no clue what changes might have affected this drastic change in brightness.

  1. Troubleshooting attempts you’ve made?

I manually set the exposure to 0, but this does not change much.

  1. What help do you need?

Any tips on handling exposure are welcomed. I wonder if the exposure of the individual cameras can be changed independently or whether there is something like an auto exposure mode.

Unfortunately, at the moment Camarray doesn’t support setting exposure individually, and it doesn’t support auto exposure either.
