Title:
撮像装置、情報取得方法及び情報取得プログラム
Document Type and Number:
Japanese Patent JP6911136
Kind Code:
B2
Abstract:
There are provided an imaging device, an information acquisition method, and an information acquisition program that can simply and accurately acquire information related to a ray angle with respect to an image sensor in a case where subject light is incident on the image sensor through an interchangeable lens even though the interchangeable lens having no compatibility is mounted on the imaging device. Under focusing on the fact that a ratio between the outputs of a first phase difference pixel (PA) and a G pixel serving as a normal pixel, which are provided on an image sensor and have different incidence angle characteristics, and information related to a ray angle with respect to the image sensor, which is obtained in a case where subject light is incident on the image sensor through an interchangeable lens, have a correspondence relationship, the ratio between the outputs of the first phase difference pixel (PA) and the G pixel is calculated and an F-Number is acquired on the basis of the calculated ratio.
