Abstract
A light detection device includes a controller that controls electric potentials of a charge collection electrode and a transfer gate electrode so that potential energy in a region immediately below the charge collection electrode is a first level, and potential energy in a region immediately below the transfer gate electrode is higher than the potential energy in the region immediately below the charge collection electrode in a first period, and so that the potential energy in the region immediately below the charge collection electrode is a second level higher than the first level, and the potential energy in the region immediately below the transfer gate electrode is lower than the potential energy in the region immediately below the charge collection electrode in a second period after the first period.
