Abstract:
(EN) Provided are an image capturing device, an information acquisition method and an information acquisition program which are capable of simply and accurately acquiring information related to a beam angle with respect to an image sensor when object light is incident to the image sensor through an interchangeable lens, even when the interchangeable lens that does not have compatibility is mounted for capturing an image. According to the present invention, in light of the fact that a ratio of outputs of a first phase difference pixel (PA) and a typical G pixel on the image sensor, the outputs having different incident angle characteristics, has a correspondence relationship with the information (F value) related to the beam angle with respect to the image sensor when the object light is incident to the image sensor through the interchangeable lens, the ratio of the output of the first phase difference pixel (PA) to the output of the G pixel is calculated and the F value is acquired on the basis of the calculated ratio.
(FR) L'invention concerne un dispositif de capture d'images, un procédé d'acquisition d'informations et un programme d'acquisition d'informations qui permettent d'acquérir simplement et avec précision des informations relatives à un angle de faisceau par rapport à un capteur d'images lorsque la lumière de l'objet est incidente sur le capteur d'images à travers une lentille interchangeable, même lorsque la lentille interchangeable qui n'est pas compatible est montée pour capturer une image. Selon la présente invention, comme il existe une relation de correspondance entre le rapport des sorties d'un premier pixel de différence de phase (PA) et d'un pixel typique G sur le capteur d'images, les sorties ayant des caractéristiques d'angle d'incidence différentes, et les informations (valeurs F) associées à l'angle de faisceau par rapport au capteur d'images lorsque la lumière de l'objet est incidente sur le capteur d'images à travers la lentille interchangeable, le rapport de la sortie du premier pixel de différence de phase (PA) à la sortie du pixel G est calculé et la valeur F est acquise sur la base du rapport calculé.
(JA) 互換性のない交換レンズが撮像装着された場合であっても、その交換レンズを通じて被写体光がイメージセンサに入射する際の、イメージセンサに対する光線角度に関連する情報を簡単かつ精度よく取得することができる撮像装置、情報取得方法及び情報取得プログラムを提供する。入射角特性が異なるイメージセンサ上の第1の位相差画素(PA)と通常画素であるG画素との各出力の比と、交換レンズを通じて被写体光がイメージセンサに入射する際の、イメージセンサに対する光線角度に関連する情報(F値)とが対応関係を有することに着目し、第1の位相差画素(PA)とG画素との各出力の比を算出し、算出した比に基づいてF値を取得するようにしている。
