A solid-state imaging apparatus includes a charge-coupled device having photoelectric converting means for accumulating charges corresponding to incident light rays and having a charge storage means for storing and transforming said accumulated charges during periods determined by a bias signal. Means are provided for controlling the period of the bias signal and read-out means are provided for obtaining the video signal from the charge-coupled device.

CCD Imager operable in single frame and repetitive frame modes

A color signal imaging apparatus includes a charge-coupled device to convert a light signal to an electrical video signal. The time during which charges are accumulated in the imaging area of the charge-coupled device is made variable so as to enable the ready compensation of the video signal components.

Solid-state color imaging apparatus having charge-coupled devices

A system for mixing and/or keying video signals includes a number of video signal processors each of which includes a charge-coupled device as a variable delay element to bring about phase coincidence among a plurality of video signals. The amplitude of the delayed video signal from the charge-coupled device is controlled, and the amplitude-controlled video signals are mixed.
