Abstract

A solid state motion analysis system stores 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. The motion analysis system includes a solid state imager which is selectively operable at different frame rates and further includes a solid state memory for storing a plurality of image frames. A trigger circuit includes a telephoto sensor which senses a change in a scene being imaged by the motion analysis system. When a scene change is sensed, the trigger circuit produces a trigger signal to alter the mode of operation of the motion analysis system. Thus, storage of image frames in the solid state memory may be started or stopped when a change in luminance of the scene occurs.
