I'm not sure where to ask this question:)

I have a software in which a camera of manufacturer SUMIX is supported. The software is in Delphi 6, and works well. The drivers are needed to view the camera image on the software.

Now the client wants the software to be able to support multiple cameras, and not just manufacturer SUMIX but any camera that is suitable for the application.

Is this possible via a video/graphics card? As in any camera can be connected to the card and display the image on the software screen?

The camera is smx-150m also ( and will be USB because of the cost involved.

Is is possible using something like framegrabber I mean to say if I connect the frame grabber to my system, I can connect any camera to the frame grabber and then display the image through the frame grabber on the software screen?

Which interface do those cameras have? – Alex P. Feb 4 '13 at 11:16
@AlexP. They are USB cameras – psqluser Feb 4 '13 at 11:18
Why would you use a USB camera with a framegrabber? – Ignacio Vazquez-Abrams Feb 5 '13 at 5:18
@IgnacioVazquez-Abrams the current camera is USB, i wanted to know if frame grabber can support multiple cameras of different manufacturer. If its not USB also – psqluser Feb 5 '13 at 6:54
Framegrabbers are meant to connect to "legacy" video connections such as composite; USB cameras... connect directly to the computer. – Ignacio Vazquez-Abrams Feb 5 '13 at 7:01

If those cameras are USB-based, then your software can use Windows Image Acquisition (WIA) and/or Windows Portable Devices (WPD) API to talk to virtually any camera that identifies itself as such.

Here's an example using DirectShow basically just a port of C++ PlayCap to Delphi, or here are some example of using WIA to get the images and
