IMAGING APPARATUS AND IMAGING METHOD

To provide an imaging apparatus and an imaging method capable of rapidly and accurately detecting an event regardless of ambient brightness.SOLUTION: In an imaging apparatus, a pixel includes a photoelectric conversion element 311 that photoelectrically converts incident light to generate an electrical signal corresponding to the intensity of the incident light, and an address event detection unit that outputs a detection signal indicating whether the amount of change in the electrical signal exceeds a predetermined threshold. The address event detection unit includes a current-voltage conversion unit 331, a reset circuit 332, an event detection circuit 333, a threshold monitoring circuit 335, and a threshold selection circuit 334 that has a first switching unit 334a and a second switching unit 334b and selects a threshold from a plurality of threshold candidates according to the magnitude of the electrical signal.SELECTED DRAWING: Figure 24 【課題】周囲の明るさによらず、迅速かつ精度よくイベントを検出することができる撮像装置及び撮像方法を提供する。【解決手段】撮像装置において、画素は、入射光を光電変換して、入射光強度に応じた電気信号を生成する光電変換素子３１１と、電気信号の変化量が所定の閾値を超えたか否かを示す検出信号を出力するアドレスイベント検出部と、を備える。アドレスイベント検出部は、電流電圧変換部３３１と、リセット回路３３２と、イベント検出回路３３３と、閾値モニタリング回路３３５と、第１切替部３３４ａ及び第２切替部３３４ｂを有し電気信号の大きさに応じて、複数の閾値候補の中から閾値を選択する閾値選択回路３３４と、を備える。【選択図】図２４
