The present disclosure relates to a filter unit, a filter selection method, and an imaging device that allow continuously changing a transmittance of an ND filter and switching between filters to be performed more easily. A disk provided with a plurality of filters including an ND filter having a continuously variable transmittance is rotated to cause a filter corresponding to a rotational orientation of the disk among the plurality of filters provided on the disk to be arranged on an optical axis of incident light toward an image sensor. The present disclosure can be applied to, for example, a filter unit, an imaging device, electronic equipment, a filter selection method, a program, or the like.

Filter unit, filter selection method, and imaging device

An imaging device includes a light separator configured to separate light into a plurality of light bands. The imaging device further includes a plurality of imaging elements. Each of the plurality of imaging elements is configured to receive one of the plurality of light bands and to generate a corresponding signal. Each of the plurality of imaging elements has a pixel size for generating a 4K resolution image signal including at least 3840 horizontal pixels and at least 2160 vertical pixels on a display. A registration error among the plurality of imaging elements is equal to or less than a threshold of 20% of a pixel size in the plurality of image elements.

Imaging device, manufacturing method thereof, and medical imaging system

An imaging device includes a light separator that separates light into light bands, and imaging elements that each receives one of the light bands and generates a corresponding signal. Each of the imaging elements has a pixel size of at most 2.5 &#x3bc;m by 2.5 &#x3bc;m. A registration error among the imaging elements is equal to or less than a threshold determined according to the pixel size.

An aberration correction apparatus includes an aberration information acquisition unit which acquires aberration information from an imaging lens; a spectroscopic characteristic information acquisition unit which acquires spectroscopic characteristic information of an imaging device which performs a photoelectric conversion of an optical image that is formed in the imaging lens; and an aberration information correction unit which performs a correction according to the spectroscopic characteristic information with respect to the acquired aberration information.
