I have two acA2040-180km cameras which are connected to 2 NI PCIe-1433 framegrabbers, I am monitoring my cameras by LabView, maximum allowable frame rate is about 187 for full resolution images, but I just need a small fraction of the images, I know if I make the images smaller, FPS will get higher, but it isn't possible by changing the image size in NI MAX, I've also tried to change the size by defining the region of interest in the grab setup.vi, but it would be after going to camera so it isn't the case as well, so I need a VI to go to the camera before starting to take photo and define the region of interest which is going to be captured, would you please help me to find it? Please help me, this problem get me stuck!!!
