Abstract: An imager and an analog to digital converter yield a series of digital signals from successive frames of images of scenes in which selected types of high-speed events may take place. The signals are sampled, and changes in the sampled signals typically indicative of such events are detected. Random access memory temporarily stores a sequence of the signals including each such changed signal. Analytic circuitry determines whether the sequence contains a record of such an event, and, if it does, provides a videotape record of the event.
