I'm trying to use Hamamatsu camera to record sequence images. The Hamamatsu camera I'm using is C4742-95-12ER. It has maximum fps of 8Hz. Becuase using labview driver cannot change the binning of the camera, I used the driver offered on Hamamatsu website and interface with IMAQ. When I just show image on front panel and set Wait till next ms at 125ms, the real loop time period fluctuate about 125ms, which is consistent with the 8Hz. However, when I switch the Start recording button on so that image file is saved as TIFF file into hard disk, the rate jumps way below the 125ms.
Another question I have for my application is that, if I understand it correctly, the camera records the image and store it in the buffer before the labview calls the image. Is there a way to know at what exact time the image is taken or is there a way to set the exactly interval between two frames (the interval between two sequential images are taken by the camera)?
Thank you very much.
Best,
Charles

Becuase it takes longer to write the data to disk than to acquire and display.
YOu may want to repost this Q to the Vison board for moe exposure.
