摘要：
A calibration mode signal line to which sensor cells are commonly connected is arranged. In a calibration mode, a calibration mode signal is supplied to the sensor cells through the calibration mode signal line to designate calibration. In each sensor cell, when the calibration mode signal is being supplied from the calibration mode signal line, and the sensor cell is selected by the decoder, calibration operation of adjusting the detection sensitivity of a sensor circuit is executed using a calibration circuit.
