The essential feature of the charge storage principle is that, during part at least of a picture frame period, the photoelectric emission due to the incident light falling on a mosaic of photoelectric cells is stored as a charge on the mosaic, each of the cells of which is associated with a capacitor. The capacitors are then discharged in sequence by a switching mechanism, such as a beam of electrons: the resulting train of electrical pulses constitutes the picture signal.
