FrameRate decrease By increasing exposure_time

Hi
when i use arv_camera_set_exposure_time(camera, 500000);
frame rate become 2 hz
and when i use arv_camera_set_exposure_time(camera, 1000);
frame rate become 30 hz
i dont really know why?
i only copy paste sample code form
https://github.com/kushalvyas/Aravis-OpenCV-Wrapper/blob/master/src/Camera.cpp
and compile with g++
best regards

If you set exposure time to 500000, which means 0.5 s, your camera can not send more than 2 image per second.

If you set exposure to 1000, you will get either de frame rate limit you have previously set, or the hardware frame rate limit of your camera.

Emmanuel.

Thank you for fast response
