Abstract: A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to an operation recommendation condition under which an operation of a mechanical correction unit which corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended. The operation control unit controls the operation of the mechanical correction unit and an operation of an electronic correction unit which corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element. In a case where a state where the related amount acquired in the acquisition unit satisfies the operation recommendation condition does not continue for a setting period defined by a time series of a plurality of consecutive times, the operation control unit performs a control for operating only the electronic correction unit out of the mechanical correction unit and the electronic correction unit.

Abstract: A shake correction control device includes an acquisition unit and an operation control unit. The acquisition unit acquires, for each predetermined time, a related amount related to each of a first operation recommendation condition under which an operation of a mechanical correction unit that corrects a shake of a subject image by mechanically moving at least one of a correction optical system or an imaging element is recommended, and a second operation recommendation condition under which an operation of an electronic correction unit that corrects the shake by performing image processing on an image obtained by imaging performed by the imaging element is recommended. The operation control unit performs a control for selectively operating the mechanical correction unit and the electronic correction unit at a subsequent time of a plurality of consecutive times depending on the first operation recommendation condition, the second operation recommendation condition, and a plurality of related amounts that are the related amounts acquired by the acquisition unit and correspond to the plurality of consecutive times.

Abstract: An image capturing device includes an image capturing section that captures first video data having a frame cycle of a first frame cycle and an exposure time for one frame shorter than the first frame cycle, an image acquisition section that acquires the first video data captured by the image capturing section, a detection section that detects a flicker of a light source in the first video data, and an image capturing frame cycle control section that controls the frame cycle of the image capturing in the image capturing section. The image capturing frame cycle control section changes the frame cycle of the first video data captured by the image capturing section from the first frame cycle to a second frame cycle, which is a frame cycle shorter than the first frame cycle, in a case where the detection section detects the flicker.

Abstract: Provided are an image processing device capable of performing compression processing on a video captured in each video capturing mode according to a first video capturing mode and a second video capturing mode with different capturing conditions. A possible range of a quantization parameter applied in a case where the video is compressed is made different in the first video capturing mode and the second video capturing mode with different capturing conditions. The quantization parameter is determined within a first range in a case of the first video capturing mode, and the quantization parameter is determined within a second range narrower than the first range in a case of the second video capturing mode. In particular, a second upper limit value of the second range is smaller than a first upper limit value of the first range, and a second lower limit value of the second range is larger than a first lower limit value of the first range.

Abstract: An imaging system includes a processor, a first imaging apparatus including a first optical system, and a second imaging apparatus including a second optical system. A focal length of the first optical system is longer than a focal length of the second optical system. The processor performs registration between a first captured image obtained by imaging with the first imaging apparatus and a second captured image obtained by imaging with the second imaging apparatus, in at least two locations including an end part of an angle of view used for imaging with the imaging system, and acquires angle-of-view related information that is related to the angle of view based on a registration result.
