I think the cheapest ntsc camera connected to the cheapest pci framegrabber with bt848 or equivalent will do much better, and it's not a lot more expensive. quoting an article I picked months ago (author first name is mark...) --- If you're looking for frame rate, go get a regular CCD camera with NTSC output and a Bt8x8 based capture card. You can get a card that's basically an 878 and nothing else for $20 at www.computergeeks.com (#include std_disclaimer.h) and OEM version STB DesktopTV cards on eBay for $30 pretty regularly. The geeks also have an outstanding deal on those itty bitty Pixera CCDs. ($32 for a color CCD camera smaller than your thumb, in a handsome black plastic package) If you want to see if some other model is faster, IBM PC Camera Pro's are selling for $60 with a $50 rebate here: https://secure.nac.net/harmony/results2.asp?Manufacturer=IBM+PC+Cameras&MANUFACTURERSEARCH.x=4 --- > If you have any comment - specially about the choice of the cameras (should > be small, resist to shocks and vibrations and as cheap as possible) I'm very > interested too ! > > Thank you for your help, > > -Eric > > -- > Eric Pichon > PhD Student > (213) 821 3012 > iLab 28D > Hedco Neuroscience Building > University of Southern California > Los Angeles CA 90089 > > > > _______________________________________________ > Video4linux-list mailing list > Video4linux-list@xxxxxxxxxx > https://listman.redhat.com/mailman/listinfo/video4linux-list -- Emmanuel Michon Chef de projet REALmagic France SAS Mobile: 0685316107 GPGkeyID: D2997E42
