Abstract
A set of voltage output units outputs the light intensity detected by a photodetection device in the form of a voltage value. With the set of voltage output units, the capacitance of the cathode terminal of a photodiode PD provided within the pixel is charged or discharged using the photoelectric current. A current output unit outputs photoelectric current Iph flowing from the photodetection device. The current output unit includes a current output transistor provided between one terminal of the photodetection device and the data line. A pixel circuit effects control of the pixel so as to activate either the set of the voltage output units or the current output unit, thereby outputting either voltage value or photoelectric current to the data line connected to the pixel.
