Abstract: Provided are an imaging device capable of assisting focusing without giving uncomfortable feeling, a focusing assistance method thereof, and a focusing assistance program thereof. In a case where manual focusing is assisted by moving an image sensor, a focus adjustment speed by an imaging lens is detected. In a case where the focus adjustment speed by the imaging lens is reduced to a threshold value or less, the assistance is started by moving the image sensor. At this time, a focusing assistance unit is brought into an in-focus state by controlling the movement of the image sensor such that the sum of the focus adjustment speed by the imaging lens and a focus adjustment speed by the movement of the image sensor is set to a speed equal to or less than the threshold value.

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).

Abstract: An imaging element captures an optical image incident through an imaging lens. A finder device is configured to be capable of observing the optical image. An EVFLCD displays information to be observable in a state of being overlapped on or being close to the optical image, in the finder device. An EVF display controller controls the EVFLCD so that target color temperature information indicating a color temperature that is a target of color temperature adjustment and image color temperature information indicating a color temperature of the captured image are displayed as the information. A color temperature adjustment unit adjusts the color temperature of the captured image obtained by capturing the optical image using the imaging element based on a color temperature adjustment operation. In a case where the color temperature adjustment operation is performed, the image color temperature information is changed in accordance with an adjustment operation amount.

Abstract: 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).
