Image acquisition using video capture card

Question

I am developing an application for Single fiber fusion splicer...my application basically has to capture the picture from the splicer using a Video capture card...Is it possible to use IMAQ session to get the picture from the card,store it a file and display the same using labview??or is there any other suitable way instead of IMAQ???

Cyril,
A typical image acquisition system consists of the following
components:
Camera » Framegrabber board » Image Acquisition Software »
Image Processing Software
The software in this application is of course LabVIEW.  The ease of integration of it with your
camera and framegrabber board is dependent on a number of variables and I
discuss that further in the rest of this post.
Camera
It looks like you already have a camera picked out, but I could not find
any information on the VHR-1000 on the internet.  Who is the manufacturer?  Can you provide a link to information
available about it online?  NI does
not actually make cameras; we simply connect with third party
cameras.  We have a list of the
various cameras that are tested and supported by our hardware available at
http://www.ni.com/cameras
Here are two more documents that will discuss camera options in more
detail:

Framegrabber
board
The framegrabber board is what will be responsible for taking the signals
from your camera, either digital or analog, manipulating them
appropriately, and storing them in computer memory.
The framegrabber board you choose will largely depend on the camera you
choose and the interface it uses. (Interfaces are discussed in the Image
Acquistion document mentioned earlier)
It looks like you already have a Domino Maxi framegrabber board, which
LabVIEW may or may not be able to interface with.  Could you please provide more
information and possibly a link to some info on this framegrabber board?

Image
Acquisition Software
The Image Acquisition software is the software responsible for bringing
images into the computer in conjunction with the framegrabber board or
IEEE-1394 bus.  Depending on your
interface, you will need either NI-IMAQ (framegrabber) or NI-IMAQdx
(IEEE-1394).
Image
Processing Software
For image processing in LabVIEW, you will need the Vision Development
Module.  It’s product page can be
found here:
Vision Development Module
http://www.ni.com/vision/vdm.htm
This software will enable you to do any type of image processing that your
application may require.
Those are the basic components of an image acquisition
system.  Hopefully you will be able to
follow those links and gain a better understanding of what exactly you need to
be able to setup the kind of system you are looking for.  This presentation provides a great deal of
general information and may be able to answer some more specific questions you
have:

It also discusses camera and lens selection with respect to
the image size and detail that you need. 
Please let us know if you have any further questions related to this.
