Patent number: 11991449Abstract: Provided is an imaging apparatus that obtains a video with a resolution of satisfactory quality and a small angle of view from a video with a large angle of view through real-time image processing. An imaging apparatus has an imaging element that captures an optical image of a standard video with a first angle of view, and a control unit that includes a first mode and a second mode as a video imaging mode and records video data of a video based on the optical image. The control unit executes first recording processing of recording video data of the standard video using the imaging element in the first mode. The control unit executes setting processing of setting a recording region with a second angle of view smaller than the first angle of view in the standard video and second recording processing of recording a video data of a recorded video of the recording region in the second mode.Type: GrantFiled: June 12, 2022Date of Patent: May 21, 2024Assignee: FUJIFILM CorporationInventors: Yuya Nishio, Tetsu Wada, Koichi Tanaka, Yukinori Nishiyama
