Abstract
A light-receiving apparatus (1a) includes a counting unit (11), a setting unit (12), and an acquiring unit (13). The counting unit is configured to measure a detection number of times that represents the number of times incidence of a photon to a light-receiving element has been detected within an exposure period and to output a counted value. The setting unit is configured to set a cycle of updating time information in accordance with an elapsed time during the exposure period. The acquiring unit is configured to acquire the time information indicating a time at which the counted value reaches a threshold before the exposure period elapses.
