Solid-state imaging apparatus, imaging method, and imaging system

摘要

A solid-state imaging apparatus 10 includes a solid-state imaging device 40, and a color filter 16 constituted of a first color filter 16a (first filter) and a second color filter 16b (second filter). The solid-state imaging device 40 photoelectrically converts light incident to a face S1 (first face) thereof to thereby capture an image of an object to be imaged. Arranged on the face S1 of the solid-state imaging device 40 is the first color filter 16a and second color filter 16b. The first color filter 16a is a filter that allows first wavelength band light to be selectively transmitted therethrough; the second color filter 16b is a filter that allows second wavelength band light in the longer wavelength side relative to the first wavelength band to be selectively transmitted therethrough.

主权项

1. An image system comprising:
a first light receiving unit detecting a near-infrared light; a second light receiving unit arranged so as not to overlap the first light receiving unit when viewed from a direction of light entering the first light receiving unit and detecting a first wavelength band light; a first light source arranged around the first light receiving unit and generating the near-infrared light; and a calculation unit configured to calculate a difference image between a first image being an image of an object to be imaged obtained by the near-infrared light entering the first light receiving unit and a second image being an image of the object obtained by the first wavelength band light entering the second light receiving unit, wherein the first wavelength band light has shorter wavelength than the near-infrared light.
