Video Grab and Snap without IMAQ Vision

[Arno Euteneuer]

Hi,
In a certain LabView application I need a window showing continuously
the picture from a video camera (i.e. a grab). Additionally I would like
to save single pictures (i.e. perform a snap) in a bitmap file (BMP,
JPG, TIF or something like this).
I know that IMAQ Vision offers all these possibilities, but somehow I
think that IMAQ Vision is kind of a overkill for only three commands
(i.e. grab, snap and save image).
Does anybody know a cheaper solution for my problem?

At the moment I use a NI framegrabber pci-1411 (but also my graphics
card -a ELSA ERAZOR III- has a video in port which could be used). The
SetUp-Software of the NI Framegrabber installed a very nice tool in the
"measurement & automation" part o
f the Windows Explorer which offers
exactly what I need (i.e. snap, grab and save image). Is it perhaps
possible to call a DLL of this tool from within LabView?

Eric Eilebrecht wrote a utility that captures frames from Video For Windows
video capture devices. Any video device that is registered as the windows
default vieo input device will work. I have used it and it works well.

Dear Jim,
Thank you very much! It works very well...

Is the video window that it opens part of the front panel so it can also be
Web-enabled using inetrnet tool kit or LV 5.1?

[Jim_Kring]

The functions in the utility I mentioned create a bitmap or 2-D array of intensity.
This can be displayed with the intensity chart on a front panel. Or you
can save this as a jpg or bitmap and publish it to the web.

Jim King,

Thanks. But what I meant was real-time image display on the Web like other
web-cam software. Since front panels can be web-enabled using Internet Developer's
toolkit(or even with LV 5.1 for monitoring and not control),
if the image is (or can be made) as part of the front panel, it can be easily
Web-enabled. That is the reason I asked if it is part of the front panel.

Pegasus software has ActiveX control CapturePro that lets you incorporate
video directly in the front panel. It is $199.00 and I am not related to
that company. You can always just capture frames using previously mentioned
VI's since it is hard to see a need for 30 fps images on web.
