Abstract
Official abstract text for this publication.
An electronic device includes: a light detection circuit having a first light sensor and a second light sensor each generating a photocurrent by photoelectric conversion, a resistive element which allows a difference between the photocurrents generated by the first light sensor and the second light sensor to flow, and a voltage detection circuit which detects a voltage generated by the flow of the differential photocurrent through the resistive element, said electronic device being controlled in operation by an output signal of the light detection circuit; a storing unit charged each time the electronic device is operated; and a rectifying element provided between the storing unit and the resistive element. A current with which the storing unit is charged is made to flow to the resistive element through the rectifying element.
