Abstract

A device and method for generating output trigger signals, for firing one or more light sources, from input trigger signals generated by a vision processor. The input trigger signals are first accepted from the vision processor. Next, output triggers are determined, in response to the input trigger signals, based on a stored lighting program. Finally the output trigger signals are generated based on the determined output triggers.
