I think it would also suffer from the same thing I had with one of the HD
Studio models, and am now with the Logitech 920 I'm screwing with now.
Waaaayyy too hi def = way too much data to process, so its 4 to 5 seconds
after the mill & camera have stopped before you actually see the final
image in the backplot. Putting a util.crop stanza in it right after the
v4l stanza (in the camviewcfg file) and cropping it down to 250x400
(roughly, it steps in fixed quantities) helps, but that cameras
2500xwhatever format simply wastes to much time flooding the system with
data to be usable. (IMO) Native frame rate is about a frame a second.
So I just bought an "endoscope" camera off ebay for $22. Its about the
size of a AAA battery, 2 meter usb cord, self illuminating 640x480, 8 bit
color, should be many times faster in its imaging output with the reduced
amount of data to handle. Ought to be here by the 18th.
Cheers, Gene
