Re: [W] Image acquisition
Hamid, I have to upgrade an old Turbo Pascal (DOS) application to LabVIEW with the currently perfectly working hardware. The camera is cooled with liquid N2. I've already began to write an interface to their PVCAM DLL and it shouldn't required more than a dozen of CLNs to get what I need. Thanks to those who replied.

I did not spend much time but it seems to me that the camera is made by Roperscientific and they also provide the frame grabber (PCI bus). By the sound of it, I guess the camera is RS170 and most probably has some special features which makes is so special! (I guess it communicates with the card). Now, I don't know what exactly you want to do? I guessed you want to write a particular program in LV. If you want to have the functionality of PVCAM (I think it is Roper's software) then you will need more information regarding their DDL's and most probably their SDK. If you can get hold of the pointer to the pixel values in the memory, (assuming you would know the image format) then the rest of the job is a piece of cake! But getting hold of "that" pointer may not be an easy job. What would I do? I would buy a frame grabber from NI and a compatible camera according to my application and then IMAQ 7 and viola!

[W] Image acquisition
Hello all. I'm not familiar with image acquisition and I have to communicate with a CCD camera, Photometrics CE 300, using its driver PVCAM. The camera acquires a spectrum and the only processing required is to sum horizontal or vertical lines into bins. I have LabVIEW 7 Pro and I would like to know if someone here can tell me what else is required to get this job done. Thanks Jean-Pierre Drolet Avensys.

RE: [W] Image acquisition
I don't really see a need for anything else for your application. If you are using a non-NI driver to acquire from the image, you should be getting a 2D array from the camera. If not, you should be able to easily convert it to a 2D array. The summing operations are standard array manipulation. You can always display the results using an intensity plot or picture control. If you want higher speed, you could use the new image control in LV 7. You might have to install IMAQ to get that control.
