Hello everybody,
I need some help choosing a frame grabber.
I'm interesetd in simple applications and I need a frame grabber that
provides not only compressed stream or compressed images but also
bitmap frames. It is for teaching applications.
Can you provide me some indication/name of frame grabber that supports
this characteristics?
If you don't want to give name of commercial products on the NG, can
you send me a mail?
Thanks a lot Giovanni


Hi Giovanni,

If you have several students who need to access images from a camera you
could get a network camera and connect it direct to your LAN. No need for a
frame grabber. Most of these produce jpg images but there are some that give
you uncompressed.
Lumenera
Tattile
iqeye
vision components
JAI Pulnix
Basler
Dalsa
Pleora
....

You can also look at USB2 and firewire cameras which are becomming popular
the image source
AVT
Sony
....

The only good reason to choose a framegraber now is a) very high data rates
that require a 64bit PCI-X or PCI Express bandwidth or if you have
specialised sensors.
