In a CCD, especially in an image sensor device, the information density can be doubled by sequentially switching the electrodes between a clock signal and a reference signal. Clock signals and reference signals are obtained as output signals of a shift register controlled by a monophase or multiphase clock. The register is provided, for example, using C-MOS technology. Information at the input terminal of the first stage of the shift register in combination with clock pulse signals at the register clock, determine the output signals of the next stage of the shift register. Hence, these input signals determine the voltage variations at the electrodes connected to the outputs of the register stages.
