Title (EN) IMAGING DEVICE, IMAGING METHOD, AND IMAGING PROGRAM
(FR) DISPOSITIF D’IMAGERIE, PROCÉDÉ D’IMAGERIE ET PROGRAMME D’IMAGERIE
(JA) 撮像装置、撮像方法及び撮像プログラム
Abstract:
(EN) Provided are an imaging device, an imaging method, and an imaging program with which it is possible to perform focus control using an image sensor that has a phase-contrast pixel group, and to perform highly precise automatic focal-point adjustment even when the image sensor is inclined and tilt photography is performed. A light-receiving surface of an image sensor (201) is inclined relative to the optical axis (L) of an imaging optical system on the basis of a tilt command from an operation unit (222), whereby tilt photography is performed. In addition, the image sensor (201) used has a first phase-contrast pixel group and a second phase-contrast pixel group, whereby phase contrast AF is performed. In particular, after the start of phase contrast AF is received, in the period until when the phase contrast AF is cancelled, either the reception of tilt commands from the operation unit (222) toward a specific direction is prohibited or movement of a tilt drive unit (209B) in the specific direction is prohibited, enabling phase contrast AF to be satisfactorily performed.
(FR) La présente invention concerne un dispositif d’imagerie, un procédé d’imagerie et un programme d’imagerie avec lesquels il est possible d’effectuer une commande de mise au point au moyen d’un capteur d’image qui comporte un groupe de pixels à contraste de phase, et d'effectuer un réglage de point focal automatique hautement précis, même lorsque le capteur d’image est incliné et une photographie d’inclinaison est effectuée. Une surface de réception de lumière d’un capteur d’image (201) est inclinée par rapport à l’axe optique (L) d’un système optique d’imagerie sur la base d’une commande d’inclinaison provenant d’une unité opérationnelle (222), de sorte qu’une photographie d’inclinaison soit effectuée. En outre, le capteur d’image (201) utilisé comporte un premier groupe de pixels à contraste de phase et un deuxième groupe de pixels à contraste de phase, de sorte qu’une mise au point automatique (AF) à contraste de phase soit effectuée. En particulier, une fois que le début de l’AF de contraste de phase est reçu, dans la période allant jusqu’à l'annulation du contraste de phase AF, la réception de commandes d’inclinaison depuis l’unité opérationnelle (222) dans une direction spécifique est interdite ou le déplacement d’une unité d’entraînement d’inclinaison (209B) dans la direction spécifique est interdit, ce qui permet qu’un AF à contraste de phase soit effectué de façon satisfaisante.
(JA) 位相差画素群を有するイメージセンサを使用して合焦制御を行うことができ、かつイメージセンサを傾けてあおり撮影を行う場合でも精度の高い自動焦点調節を行うことができる撮像装置、撮像方法及び撮像プログラムを提供する。操作部(222)からのあおり指示に基づいてイメージセンサ(201)の受光面を撮像光学系の光軸(L)に対して傾けることで、あおり撮影を行う。また、第1の位相差画素群及び第2の位相差画素群を有するイメージセンサ(201)を使用することで、位相差AFを行う。特に位相差AFの開始を受け付けた後、位相差AFが解除されるまでの期間、操作部(222)からの特定の方向へのあおり指示の受け付けを禁止し、又はあおり駆動部(209B)の特定の方向への動作を禁止し、良好に位相差AFを可能にする。
