Hello guys,

I need to develop a pc-projector-camera system.
The pc generates color patterns to be projected by the projector, and the camera must capture the images illuminated by the patterns.

Camera / projector synchronization is necessary to guarantee
that a given slide will be projected by the projector
and captured by the camera at the same time.

I know that the synchronization can be done using genlock.
But I don`t know how to do that using digital equipment.

Can you tell me camcorders or projector models, professional or semi-professional, that have a genlock pin ?

Is there any other way I can synchronize the camera and projector with a signal sent by the computer ?
