Abstract
A self-contained video camera/recorder includes means for generating a video signal at a slow-frame rate corresponding to a submultiple of a standard television field rate. The slow-frame signal is recorded and played back at the slow-frame rate thereby reducing the bandwidth requirements of the recorder. Upon playback, the slow-frame signal is buffered, frame by frame. The buffered signal is time compressed, and each frame is repeated a number of times to yield a video signal wherein the frames occur at a standard field rate. According to the preferred embodiment of the invention, the means for generating the slow-frame video signal, and for buffering, time compressing and repeating the frames during playback, is a solid-state image sensing and signal processing device having an image sensing array, a first input register disposed for introducing signals into the sensing array, a storage array, a second input register disposed between the sensing array and the storage array for introducing signals into the storage array, and an output register for reading signals out of the storage array.
