Hi there

As there is barely any information around about Apples new iSight
camera, here's some stuff I found out:

iSight is IIDC compatible (see
carol.wins.uva.nl/~fransve/literature/1394/IIDC_Spec_v1_30.pdf) and
supports the feature set (416, 417, 419, 420, 421, 423, 424, 426, 427)
= (brightness, exposure, white balance, hue, saturation, shutter,
gain, focus, temperature(?)). More details are available through
library function calls. lidc1394 provides all the necessary functions.
Images are YUV4:2:2 (640*480, 320*200) and YUV4:1:1(640*480) encoded,
conversion functions to RGB available.

coriander is a nice piece of software to play around with, and iSight
works with it. modules libraw1394, ohci1394, ieee1394 are required
though.

I'm doing some stereo vision attempts with it.

Have fun,
Stephan
