I am using a Jetson Xavier NX with RPi Camera v2.1 (both NoIR and regular) to develop a microscopy application. The only way to take pictures seems to be using GStreamer and saving frames. But is there any way to capture only still images, without launching a stream or video feed from the sensor? When I use the video mode, I can’t use the full abilities of the RPi camera.
I have been experiencing a lot of issues with noise and extremely poor image quality. I saw some of the earlier posts about this issue and I am trying to perform proper tuning for the camera. Also unlike most applications here which are in robotics, ours is in microscopy and I need complete control of imaging parameters with close to zero automatic features. So, I was trying to feed in exposure and white balance settings in the GStreamer string using
nvarguscamera properties but it is not reflected in the images. For example, even after setting an exposure time of 0.6 seconds, the video feed output of the GStreamer was running at 20-21 fps. The edge enhancement effects are very visible even after setting it to off. What can I do about this?
