Abstract:
A signal reading apparatus includes first and second common signal lines from which a signal from a signal generation unit is output and first and second amplifier circuits and a switch configured to control a conductive state of the first and the second common signal lines. The signal reading apparatus includes a first signal reading method of reading a signal from the first common signal line after being amplified in the first amplifier circuit and reading a signal from the second common signal line after being amplified in the second amplifier circuit and a second signal reading method of turning ON the switch to read the signal from the first common signal line and the signal from the second common signal line individually after being amplified in the first amplifier circuit. The signal reading apparatus includes a control unit for controlling between the first and second signal reading methods.
