Abstract:
A light detection apparatus includes an image sensor, a signal obtaining unit, an exposure-time-period determination unit, and an exposure controller. The signal obtaining unit is configured to obtain a first dark current being a dark current of the image sensor in a first exposure time period, and a second dark current being a dark current of the image sensor in a second exposure time period. The exposure-time-period determination unit is configured to determine an optimal exposure time period of the image sensor based on the first dark current and the second dark current. The exposure controller is configured to control the image sensor to be exposed to light for the optimal exposure time period.
