Analog camera control in Matlab

Subject: Analog camera control in Matlab

I would like to connect an analog Sony camera (XC-ST51)
and acquire video rate (~30fps) movies using Matlab.

Is there a way to use an analog-to-digital converter to do
this, and will Matlab be able to control it?
Frame grabbers are an option, but they are 4x the cost of
the camera, so we are looking for other options...

Any suggestions will be welcome
Thanks,
Daphne

Using a standard analog to digital converter will be much more expensive
than using a frame grabber. Most cheap DAQ boards can not handle video
data rates.

Analog frame grabbers come in a wide range of prices. You can look at
http://www.mathworks.com/products/imaq/supportedio.html to see a list of
hardware that is supported by The Image Acquisition Toolbox.

Depending on your needs, you might be able to get by with a consumer
level TV tuner card. These normally cost on the order of $100 USD. If
you need the features of a frame grabber several vendors supported by
The Image Acquisition Toolbox produce low cost models.
