    摘要: A processing device includes: a control-signal generating unit that generates a control signal by switching a predetermined potential and a second potential that is different from the predetermined potential; multiple processing units that, if a potential of the control signal is the predetermined potential, flow a predetermined current, process and outputs an input signal, and if a potential of the control signal is the second potential, do not flow the predetermined current and do not process a signal; and a control unit that controls the control-signal generating unit such that, in a case of an operating mode in which the processing units process a signal, the control signal is a voltage signal of the predetermined potential, and in a case of a standby mode in which the processing units do not process a signal, the control signal is a voltage signal of the second potential.

    摘要: The analog signal buffer is connected with a photoelectric converter to convert an optical image to an analog signal and an analog signal processing circuit to convert the analog signal to a digital signal, and transmits the analog signal to the analog signal processing circuit. The analog signal buffer includes a first buffer having a NPN transistor; and a second buffer having a PNP transistor. The first buffer includes a circuit to block a reverse current caused in the analog signal buffer by dropping of a voltage output from the photoelectric converter.
