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?

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