Abstract

A fast frame recorder records images of an event at a fast frame rate and plays back the images at a slower frame rate to facilitate analysis of the event. Disclosed is a fast frame recorder having solid state memory capable of continuously recording an event in a circular or FIFO format until an external trigger terminates recording. By varying the delay of the external trigger, the number of image frames recorded before and after the triggering event may be varied.
