To provide a pupil detection device capable of detecting instantaneous pupil motion.SOLUTION: A pupil detection device (5) detects motion of a pupil (6) on the basis of a result of image capture by means of an image capture device (4) that captures an image including the pupil (6). The pupil detection device comprises an acquisition unit (51) and a control unit (52). The acquisition unit acquires image capture data (D1) indicating the image capture result from the image capture device. The control unit performs data processing based on the image capture data acquired by the acquisition unit. The control unit counts, on the basis of the image capture data, changes in luminance of respective pixels in a region in which the luminance has changed temporally, and detects motion of the pupil on the basis of the count of changes in luminance counted above.SELECTED DRAWING: Figure 7
【課題】瞬間的な瞳孔の動きを検出することができる瞳孔検出装置を提供する。【解決手段】瞳孔検出装置(5)は、瞳孔(6)を含んだ画像を撮像する撮像装置(4)の撮像結果に基づいて、瞳孔(6)の動きを検出する。瞳孔検出装置は、取得部(51)と、制御部(52)とを備える。取得部は、撮像装置から撮像結果を示す撮像データ(D1)を取得する。制御部は、取得部によって取得された撮像データに基づくデータ処理を実行する。制御部は、撮像データに基づいて、輝度が時間的に変化した領域における画素毎の輝度の変化を計数し、計数した輝度の変化の計数値に基づいて、瞳孔の動きを検出する。【選択図】図7
