Abstract
An imaging apparatus includes an imaging unit configured to convert an incident light flux from an optical system into an electric signal, a band-cutting element disposed between the optical system and the imaging unit, having a band-cut function of performing band-cutting to enable distinguishing between wavelengths corresponding to bright line positions of a light source having bright lines, a control unit configured to control the band-cut function of the band-cutting element, an identification unit configured to identify a light source of an image captured by the imaging unit through comparison between a first image signal captured by the imaging unit when the band-cut function of the band-cutting element is ON and a second image signal captured by the imaging unit when the band-cut function of the band-cutting element is OFF, and an image processing unit configured to perform image processing based on the light source identified by the identification unit.
