Issue with exposure time?

[llooiicc]

Hello,

I am using a Kinetix camera. I have run the live_mode.py to test with different exposure time.

PyVCAM/tests/live_mode.py

Line 12 in a401bca

cam.start_live(exp_time=20)

With the default value exp_time=20, all frames are full of 4095. So I tried with less exposure, same result... until exp_time=0 then it works.

So I ran PVCamTest software to be sure that it is not my environnement that is too luminous. But no, changing exposure affect the image.

I don't know what to do to solve this problem.

Hi, I just tested a Kinetix camera with unmodified live_mode.py sample and it seems to work quite well. Did you by any chance modify the sample and if so, can you specify in what way? Would it be possible to provide a code snippet?

I tested with unmodified live_mode.py
The unique modification I made is the exp_time parameter in cam.start_live() function.

Strange. It should work just fine. What PVCAM version are you using?

[llooiicc]

Yeah it's really strange. I don't know why it doesn't work...
I am using :
PVCAM 3.10.2
python 3.12.7
Windows 11

Enabling PVCAM logging.pdf
Would it be possible to enable our PVCAM logging system, gather PVCAM logs and send them to me to the following email address: [email protected] Please note that you will likely need to restart your IDE after enabling the PVCAM logs.

Just to make sure:

1. Enable logs
2. Run the live_mode.py
3. Stop the live_mode.py
4. Disable logs.
5. Send the log file.
