Abstract
To calculate received light quantity even when part of noise component's discharge probability is unknown, a light detection system includes a discharge probability calculating portion that calculates discharge probabilities for a first state in which a source's light with known light quantity impinges on an optical sensor, a second state in which the source's turning-on/turning-off state is the same as the first state with a drive pulse width applied to the optical sensor different from the first state, a third state in which the source's turning-on/turning-off state is different from the first and second states with the same pulse width as the first state, and a fourth state in which the source's turning-on/turning-off state is the same as the third state with the same pulse width as the second state, another discharge probability calculating portion that calculates regular and irregular discharges' probabilities, and a received light quantity calculating portion.
