Photodetector

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.
