Abstract
A charge transfer device for transferring information charge packet in accordance with a vertical synchronization signal and a horizontal synchronization signal. The charge transfer device includes a capacitor for storing information charge packet. An output amplifier is connected to the capacitor to be supplied with and operated by a first voltage. The output amplifier receives the potential at the capacitor and generates an image signal corresponding to the potential at the capacitor. The supply of the first voltage to the output amplifier is stopped during a blanking period of the vertical and horizontal synchronization signals.
