Abstract: An imaging support device includes a detection portion that, by operating a revolution mechanism that causes an imaging apparatus including a variable magnification mechanism to revolve, detects a subject image position of a target subject image showing a target subject in a captured image obtained by capturing an imaging region including the target subject by the imaging apparatus, and a control portion that perform a registration control of setting the subject image position detected by the detection portion to a specific position in the captured image for a captured image obtained by imaging performed by the imaging apparatus in accordance with changing of magnification to a telephoto side by the variable magnification mechanism.

Abstract: One embodiment according to the technology of the present disclosure provides an optical element, an optical device, an imaging apparatus, and a manufacturing method of the optical element, for capturing a multispectral image. An optical element according to an aspect of the present invention includes a plurality of optical filters including two or more optical filters that transmit light beams having at least partially different wavelength ranges, and a frame having an inclined surface portion with an optical axis center as an apex, in which the plurality of optical filters are installed on the inclined surface portion.

Abstract: Provided is an imaging apparatus that captures a multispectral image having a good image quality. An imaging apparatus (1) includes an imaging optical system (10) that includes a pupil region which is split into a plurality of regions including a first pupil region and a second pupil region different from the first pupil region, and a polarization filter which polarizes light beams passing through the first pupil region and the second pupil region in directions different from each other, an imaging element (100) that includes a first pixel which receives the light beam passing through the first pupil region and a second pixel which receives the light beam passing through the second pupil region, and a signal processing unit (200) that processes signals output from the imaging element (100), and outputs at least first image data consisting of an output signal of the first pixel and second image data consisting of an output signal of the second pixel.

Abstract: The lens holding frame is accommodated in the outer tube and is movable with respect to the outer tube in an optical axis direction (OAD) parallel to an optical axis of a lens optical system. The intermediate holding frame is a flexible frame body that constitutes the lens holding frame, is formed of a flexible material, and has a tubular shape. The intermediate holding frame is integrally provided with beam structures as abutments. The beam structures abut onto an inner circumferential surface of the outer tube in a state of being elastically deformed such that a restoring force is generated and prevent vibration caused by a gap between an outer circumferential surface of the lens holding frame and an inner circumferential surface of the outer tube.
