Abstract: An imaging support device that supports imaging performed by an imaging apparatus includes an acquisition portion that acquires an in-image shift amount between a predetermined position in a captured image obtained by capturing an imaging region by an imaging element and a position of a target subject image showing a target subject, and a focal length of the imaging apparatus, a derivation portion that derives a movement amount required for moving the position of the target subject image to a specific position by a position adjustment portion which adjusts the position of the target subject image in the captured image, based on the in-image shift amount acquired by the acquisition portion, the focal length acquired by the acquisition portion, and information related to a pixel interval of pixels in the imaging element, and an output portion that outputs the movement amount derived by the derivation portion.

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.

Abstract: A blur correction device includes: a sensor; a mechanical blur correction device; an electronic blur correction circuit that corrects the blurring by performing image processing on an image obtained through imaging of the imaging apparatus, based on the amount of blurring and operation state information about an operation state of the optical element during exposure in the imaging apparatus; and a supplementary blur correction circuit that, in a case where the mechanical blur correction device and the electronic blur correction circuit are shared and operated at a predetermined ratio during the exposure, corrects the blurring by applying, to the image, a filter determined depending on the operation state information, the predetermined ratio, the amount of blurring, and an exposure period in the imaging apparatus.

Abstract: Provided are an image processing device, an image capturing device, and an image processing method. Included are a video acquisition section that acquires a video with a variable image capturing frame rate during image capturing, an image capturing mode selection section that selects a first video capturing mode or a second video capturing mode in which an exposure time per frame is set to be shorter than that in the first video capturing mode, a compression processing selection section that selects first compression processing that prioritizes a capacity in a case where the first video capturing mode is selected or selects second compression processing that prioritizes image quality in a case where the second video capturing mode is selected, and a compression processing section that compresses the video acquired by the video acquisition section and performs the first compression processing or second compression processing selected by the compression processing selection section.

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: 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.
