イメージセンサ。[Claims for Utility Model Registration] A segment consisting of a light-receiving element whose electrical characteristics change according to incident light and an analog switch connected to the light-receiving element to detect the change in the electrical characteristics of the light-receiving element with current. In an image sensor comprising a pulse circuit in which a plurality of units are arranged and generates a clock signal for driving the analog switch ON/OFF, the rise or fall of the start pulse or end pulse of the pulse circuit A phase control means for generating a phase difference between the falling timing and the opening/closing timing of each of the analog switches is inserted between the pulse circuit and the analog switch circuit, and the phase difference controlled by the phase control means is externally controlled. An image sensor characterized in that a phase control terminal for changing according to a signal is coupled to the phase control means.
