Abstract: An image sensor includes: photoelectric conversion elements configured to receive light and accumulate a charge corresponding to an amount of received light; an imaging signal generating unit that converts the charge accumulated in each photoelectric conversion element into a voltage to generate an imaging signal; and a reference signal generating unit that generates a reference signal having a fluctuation component with a same phase as the imaging signal. The imaging signal generating unit includes: a conversion circuit that converts the charge accumulated in each photoelectric conversion element into the imaging signal; a noise eliminating circuit that eliminates a noise component included in the imaging signal; and an output circuit that outputs the imaging signal from the conversion circuit. The reference signal generating unit includes a circuit having a same structure as that of at least one of the conversion circuit, the noise eliminating circuit, and the output circuit.

Abstract: An endoscope includes an imaging circuit that generates an imaging signal. The endoscope has a transmission path that connects the imaging circuit to a control device to perform image processing on the imaging signal. The endoscope also includes a phase synchronization unit having (i) a digital control oscillator that generates a drive clock signal, and (ii) a phase digital output circuit that generates and outputs a phase digital signal to the transmission path. A first switch of the endoscope connects the transmission path to one of the control device and the phase digital output circuit, and a second switch connects the transmission path to one of the imaging circuit and the digital control oscillator.
