Of video resolution, Q-Cam and video-grabber boards

I have both setup a Q-Cam and a SPIGOT with the BG Micro
spycam.I can only judge on the local window but the picture quality from
the video-grabber camera board seems to be quite superior to
the Q-Cam.

I also noticed the same when receiving images from Mac's which
were using a digitizer and a camera. The picture were always
much sharper than Q-Cam windows which displayed at the same
time. The Q-Cam 16-64 Gray adjustment does not seems to make
any difference in tests done on a target test pattern.

As anyone notice this difference? Why? The image are always
120x160, the camera CCD resolution is in each case higher than
CU image, therefore not the limiting factor... What is happening ?

Thanks in advance for any explanation. Alain
