Beschreibung
Zusammenfassung:	A solid-state imaging device includes a photon detector that operates in a Geiger mode and outputs an output signal in accordance with incidence of a photon, a quench element that causes the photon detector to transition to a non-Geiger mode in accordance with the output signal, a control unit that, when the photon detector transitions from a Geiger mode to a non-Geiger mode, switches the quench element from a detection mode, in which the quench element is in a relatively low resistance state and the photon detector detects a photon, to a hold mode, in which the quench element is in a relatively high resistance state and holds the output signal, and a signal processing circuit that performs a predetermined process on the output signal.
