Hello. We are using a Jetson TX2 (on a Spacely carrier board by Connect Tech) and we are using a LI-IMX274-MIPI-M12 camera from Leopard Imaging. We are using GStreamer and
nvarguscamerasrc to interface the camera.
nvarguscamerasrc takes in ranges (min and max values) for exposure time, gain and ISP digital gain, and it seems an auto exposure algorithm is implemented that sets the actual values for exposure time, gain and ISP based on the brightness of the image.
Can you provide me with details about how this auto exposure algorithm works and how it prioritizes between exposure time, gain and ISP digital gain? Where exactly is this auto exposure algorithm implemented? Do you have links to the relevant source code?
Is there any way we can query the camera for the actual values used for exposure time, gain and ISP digital gain for each frame in the video stream?
