I am using a LED illumination source for a IEEE1394 camera. I am turning on/off the LED with a digital I/O. I am using the NI-IMAQ for IEEE 1394 grab acquire in Labview 7.1 to capture an image. I have a Sony DFW-X700 camera, and it takes ~ 70 ms to transfer the image data. It is my understanding that the grab acquire is running for this time plus whatever the exposure time is. I would like to turn on the LED right before the exposure time, and turn it off right after the exposure time is over. I don't know how to turn the LED off for the ~70 ms image transfer time? Is their a way to turn the LED off while the grab acquire is still transferring the image data? I want the LED to be on for the least amount of time without decreasing the exposure time anymore, and this is the only way I can think to do it. Can Labview do these two things at once? Thank you in advance for any assistance.
