Hi,
I am a graduate student working with the NVIDIA Jetson TX1 to collect some images for our HDR camera. I wanted to know if there is any way to give an ISO setting in Gstreamer while acquiring images.
We have a problem with a purple color cast on our low light images and based on my searches on the internet one of the reason might be the auto ISO setting.
I was wondering if there is a way to set the ISO then I can get rid of the purple color cast / purple hue on my low light images.
Thank you
Hi Jerry,
We are using the image sensor IMX290 from leopard imaging. We are building our own custom HDR rig using those sensors. The JetPack version we used is 4.2 . Also we used jetpack only for loading the ISO. The rest of the drivers and stuff we followed the instructions from leopard imaging.
Also we were not able to find any ISO setting in the Argus GUI application. Is there something I am missing here? Here is the image of the Argus GUI which we use: ArgusGUI — ImgBB
I will look into what you have said and hopefully find some solution. I have looked through some of the Gstreamer documentation but could not find anything on ISO settings though.
Let me know if you have more thoughts on the purple color cast or the ISO settings.
Thank you
hello bharat91,
indeed, your issue don’t seems caused by post-processing after checking your capture result.
according to your comments,
“using a specific gain value based on our theoretical calculations.”
could you please keep narrow down the issue,
couple of suggestion as below.
- please hard-core the gain values for checking.
- please exclude sensor digital gain for checking.
BTW,
may I know your commands to launch camera for testing?
please also share the parameter settings if you’re working with argus_camera.
thanks
