Ziggi-HD webcam control

["Prof J C Nash (U30A)" <nashjc uottawa ca>]

Hi,

I've just acquired an IPEVO Ziggi HD document camera. It has  2592 x 
1944 resolution, and cheese seems to run it fine as a webcam and to scan 
documents. Does a pretty good job for the price.

The one nuisance is that there is no control of the autofocus from the 
host computer in Linux, so I have to have cheese or something else 
running and press a button on the camera, which is a bit awkward and 
giggles the camera position. The Windows software (Presenter) has 
controls, though interestingly seems to only power the cam to 1600 by 
1200. It has a high similarity to cheese. One wonders ...

Using uvcdynctrl I got some feedback that the camera is nonstandard, but 
still several pages of info.

If anyone has ideas, I'm willing to poke around and see if I can 
discover a way to run the focus and possibly exposure controls. However, 
I'm mainly a scientific programmer (R, though I've done my share of 
bit-banging and assembler back in the 60s and 70s) so may be a bit 
sluggish on coding.

If someone wants me to send info etc., I suggest off-list and we'll 
report back. FYI I receive all mailing lists in digest form.
