I've been doing some extremely basic machine vision experiments for a while, using STV0680-based USB cameras attached to Linux boxes.
I now want to experiment with IR-illuminated subjects, but the cheap webcams I've been using are color cameras with IR filters.
Can someone recommend a Linux-supported USB video capture device that accepts regular NTSC input and provides at least 320x240 @ 7.5fps? With one of these I can use a cheapo B&W camera with good IR response.
Alternatively, I could see my way to constructing some custom optics and lashing a bare digital image sensor directly to one of the other pieces of hardware in the system. But in this case I would need a recommendation for a sensor chip that is:
a) available (!!) b) in a prototypable package (LCC is OK, but these weird packages that have to be fused onto the board are NOT OK).
The Omnivision OV07141-C01A or -P01A might be ideal but they are impossible to buy.
