View Full Version : Problem with external trigger

October 11, 2012, 09:27:43

I have a problem with the DFM 22BUC03-ML camera. In free-running mode it can work at 87 fps, but with external trigger it is not able to exceed 75 fps.

My configuration is:
- Resolution: 640x480
- Exposure: 1/714 s

Why can not camera work at 87fps in trigger mode?

Thank you very much.

The sequence of image acquisition is different for free running mode and trigger mode. Therefore, it is possible to achieve higher frame rates with longer exposure times, if the camera is free running, than if it runs triggered. The only way to achieve higher frame rates running triggered is using a shorter exposure time.
