Abstract:
(EN) The purpose of the present invention is to provide an image pickup device, an image pickup method, and a program, all of which enable suppressing of blurring of a subject image and performing of dynamic range expansion processes appropriate for a dark scene and a bright scene while maintaining a preset frame rate. This image pickup device is provided with: an image pickup unit; a first dynamic range expansion process unit (301) which carries out a dynamic range expansion process by generating a single composite image from a plurality of captured images; a second dynamic range expansion process unit (303) which carries out a dynamic range expansion process by correcting an output value of one captured image; and a control unit (305) which, on the basis of a sum of the time of a single frame period and the exposure time when capturing a plurality of images, causes the first or second dynamic range expansion process unit to carry out the process thereof.
(FR) L'invention concerne un dispositif de capture d'image, un procédé de capture d'image et un programme asocié, permettant de supprimer le flou d'une image de sujet et de réaliser des processus d'extension de plage dynamique appropriés pour une scène sombre et une scène lumineuse tout en maintenant une fréquence de trames prédéfinie. Le dispositif de capture d'image comprend : une unité de capture d'image ; une première unité de traitement d'extension de plage dynamique (301) qui réalise un processus d'extension de plage dynamique par génération d'une image composite unique à partir d'une pluralité d'images capturées ; une deuxième unité de traitement d'extension de plage dynamique (303) qui réalise un processus d'extension de plage dynamique par correction d'une valeur de sortie d'une image capturée ; et une unité de commande (305) qui, en fonction de la somme du temps d'une période de trame unique et du temps d'exposition lors de la capture d'une pluralité d'images, entraîne la première ou la deuxième unité de traitement d'extension de plage dynamique à réaliser ledit processus.
(JA) 本発明は、被写体像のブレを抑制し、設定されたフレームレートを維持しながら、暗いシーンおよび明るいシーンにおいて適切なダイナミックレンジ拡大処理をすることができる撮像装置、撮像方法、およびプログラムを提供することを目的とする。撮像装置は、撮像部と、複数の撮像画像から1枚の合成画像を生成することにより、ダイナミックレンジ拡大処理を行う第1のダイナミックレンジ拡大処理部(301)と、1枚の撮像画像の信号の出力値を補正することにより、ダイナミックレンジ拡大処理を行う第2のダイナミックレンジ拡大処理部(303)と、1フレーム期間の時間と、複数の撮像画像の撮像を行う場合の露光時間の合計時間とに基づいて、第1のダイナミックレンジ拡大処理部または第2のダイナミックレンジ拡大処理部による処理を実行させる制御部(305)と、を備える。
