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.

The present invention provides an imaging device and a focusing control method capable of enhancing accuracy of a focusing control regardless of subjects even when levels of detection signals of phase difference detection pixels are low. A phase difference AF processing unit (19) generates a defocus amount (Df1) from a result of a correlation operation performed with respect to detection signals obtained by adding up detection signals of plural phase difference detection pixels (52A, 52B) in a pair line (PL1) present in a selected AF area (53) and detection signals of phase difference detection pixels (52A, 52B) in pair lines (PL2, PL3) present in a selected direction among plural directions which are crossing directions crossing an X direction with respect to each of the plural phase difference detection pixels (52A, 52B) in the pair line (PL1). A system control unit (11) performs a focusing control based on the defocus amount (Df1).
