Abstract: Provided are an imaging device, an imaging device main body, and a focusing control method of an imaging device capable of adjusting a focus with high accuracy by appropriately supporting the focus adjustment in a manual manner. An image sensor movement driver (220) that moves an image sensor (210) along an optical axis (L), and an image sensor movement controller (250a) that controls the movement of the image sensor (210) by controlling the image sensor movement driver (220) are provided. In a case where a subject is focused, the image sensor movement controller (250a) starts the tracking, and controls the movement of the image sensor (210) such that a focusing state is maintained based on a defocus amount detected by the phase difference AF processing unit (132).

Abstract: A video creation method of creating a video is provided. The method includes setting, in an imaging region of a reference video having a first angle of view, one or more regions having a second angle of view different from the first angle of view, determining a selection region that is the region in which a subject of a recording target is included, switching the selection region, displaying an insertion video in a period between a display period of a pre-switching video which is a video of the selection region before the switching and a display period of a post-switching video which is a video of the selection region after the switching, and executing, during a display period of the insertion video, a process to change a displayed video from one of the pre-switching video or the post-switching video to the other of the pre-switching video or the post-switching video.

Abstract: Provided are an imaging device capable of accelerating AF and a focusing control method thereof. A focus lens drive unit (16) that drives a focus lens (12), and an image sensor movement drive unit (120) that moves an image sensor (110) along an optical axis (L) are included. A target position of the focus lens (12) for focusing on a subject is set, and the focus lens (12) is moved toward the target position. The image sensor (110) is moved before the focus lens (12) reaches the target position such that focusing is performed. A focusing state is maintained by moving the image sensor (110) so as to follow the focus lens (12) after the focusing is performed.

Abstract: A control section 11 moves an imaging lens 1 based on a detection signal from an angular velocity detection section 6 so as to correct image blurring which occurs in captured image data obtained through imaging performed by an imaging element 3. The control section 11 calculates a first motion vector between first captured image data, which is obtained through imaging performed by the imaging element 3, and second captured image data which is obtained subsequent to the first captured image data and in which image blurring is corrected. The control section 11 performs an offset correction for reducing an offset signal included in the detection signal of the angular velocity detection section 6, based on the first motion vector.
