Forcing linear gamma response for cameras

  1. Where did you get the camera module(s)? Amazon
  2. Model number of the product(s)? )OV9281
  3. What hardware/platform were you working on? Nvidia Jetson Orin Nano
  4. Instructions you have followed. (link/manual/etc.)
  5. Problems you were having?

I am using the camera for a homebuilt structured light scanner. In order for it to work, I require a linear gamma response between the camera and projector. I can not see any way to adjust the gamma curve on a UVC camera. Do you have any software tool to do this?

  1. What help do you need?

I need to be able to set a linear gamma curve for the camera.


On windows we have relevant GUI to control, on linux you can try v4l2-ctl

view control

v4l2-ctl -l


v4l2-ctl -c [control_name]=[control_value]
