1. A photodetector comprising:
a plurality of cells each configured to detect light and including:
a photodiode having anode and cathode terminals and configured to output an electrical signal upon receipt of the light,
a resistor having first and second terminals, the first terminal being connected to the anode terminal of the photodiode, and
first and second switches connected to the second terminal of the resister, wherein either the first switch or the second switch is turned on according to a selection signal;
a first output terminal connected to the first switch of each of the cells and through which a first output signal is output based on the electrical signal that has been output from the first switch;
a second output terminal connected to the second switch of each of the cells and through which a second output signal is output based on the electrical signal that has been output from the second switch;
a first connection portion connected to the first switch of each of the cells; and
a second connection portion connected to the second switch of each of the cells, wherein
the second connection portion is electrically disconnected from the first connection portion.
