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.

Telephoto sensor trigger in a solid state motion analysis system

The present invention provides apparatus for calculating the skew distortion introduced in each channel of a multi-channel longitudinal recorder when recorded information signals in at least two channels contain a detectable characteristic. In accordance with the invention, a timing signal is recorded containing certain information that is used, upon playback, to produce a reference marker which is compared with the detectable characteristics of recorded information signals to produce a measure of skew distortion.

The present invention provides apparatus for adjusting the time base of a signal that is read out from an addressable memory device. In accordance with a disclosed embodiment, coarse time base adjustment is provided by controlling the address count produced by a readout counter, while the phase of the counter clocking signal is adjusted to provide fine time base adjustment.
