ABSTRACT:
A photo detection circuit includes a photodiode whose cathode is connected to a high-potential-side power supply and whose anode is connected to a connection point; a capacitor element provided between the connection point and a low-potential-side power supply; and a switching element, provided between the connection point and the low-potential-side power supply, that switches on and off with a predetermined period. A voltage signal of the connection point is extracted as an output signal.
