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. An image sensor (201) including first phase difference pixels and second phase difference pixels is moved between a first position (P1) and a second position (P2) in the direction of an optical axis of an interchangeable lens. Information related to a ray angle with respect to the image sensor (201) in a case where subject light is incident on the image sensor (201) through the interchangeable lens is acquired on the basis of the outputs of the first and second phase difference pixels in a case where the image sensor (201) is moved to the first position (P1) and the outputs of the first and second phase difference pixels in a case where the image sensor (201) is moved to the second position (P2).
