Abstract
A time lapse video recorder includes auto monitoring circuitry for ensuring that proper recordings are being made. During the time between intermittent recording of fields by the time lapse recorder, the recorder is switched to a read mode of operation and the previously recorded field is monitored. If the monitored signal is of improper amplitude or frequency, an error detector activates an alarm. The invention may also be used with non-time lapse recorders to enable the quality of a recording to be checked without requiring rewinding of tape.
