Abstract
A video camera recorder comprises an imaging means receiving an optical image and generating an image representative video signal, and a viewfinder for viewing the optical image. A synchronizing signal generator is coupled to the imaging means and to a recording means which is coupled to the imaging means. A control means for optimizing power conservation has a first mode which enables operation of the synchronizing signal generator and inhibits operation of the imaging and recording means. In a second mode the control means enables the synchronizing signal generator and recording means for reproducing a recorded image representative video signal and inhibits operation of the imaging means. In a third mode the control means enables the imaging means, the synchronizing signal generator and the recording means for recording the image representative video signal from the imaging means.
