A light detection apparatus has an array of first light detectors arranged at a first interval and configured to convert reception light into first signals, second light detectors having a first crosstalk rate and configured to convert reception light into second signals, wherein surfaces of the second light detectors are shielded from light, third light detectors having a second crosstalk rate different from the first crosstalk rate and configured to convert reception light into third signals, wherein surfaces of the third light detectors are shielded from light, and control circuitry configured to control an operation point of the array based on the second signals and the third signals.
