IMAGING APPARATUS HAVING LIGHT SOURCE IDENTIFICATION AND IMAGE QUALITY-CORRECTING FUNCTION AND CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To easily and accurately identify various kinds of light sources including a bright-line light light-source in an image obtained from an imaging apparatus.SOLUTION: An image apparatus comprises: an imaging unit for converting 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 light wavelengths corresponding to bright line positions of a light source having bright lines; a control unit for controlling 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. In the control unit, imaging is performed by the imaging unit by activating the band-cut function corresponding to the light source identified by the identification unit.
