I’ve noticed strange behavior with LCCV and OpenCV and the Raspberry Pi’s HQ Camera or GS Camera.
I’m having problems manually setting ExposureTime, Gain, and Shutter. I use C++.
About two months ago, everything worked fine; I was using OpenCV 4.10 with LCCV.
With:
lccv::PiCamera cam;
cam.options->ev = Exposure; // some value
cam.options->gain = Gain;
cam.options->shutter = Shutter;
I was able to set everything individually, without the automatic function.
After reinstalling the entire system with OpenCV version 4.12, this was no longer possible.
Another reinstallation with OpenCV 4.13 also didn’t produce the desired function.
Fortunately, I have an image with OpenCV 4.10. But when I install updates (sudo apt-get update; sudo apt-get upgrade), I experience the same unwanted behavior.
Unfortunately, I haven’t found a precise description of the function of the various options.
I’m hoping for some good advice on how to resolve this unwanted behavior.
Thank you
