Title:
IMAGING DEVICE AND IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/047825
Kind Code:
A1
Abstract:
Provided are an imaging device and an imaging method with which it is possible to obtain an image that allows good visual recognition of subjects, said subjects being a heat source that radiates infrared light and the surroundings of the heat source which reflect visible light. An imaging device (1) captures a near-infrared image and a visible image, and comprises: an imaging optical system (100) that has transmissive characteristics in the near-infrared light wavelength band and the visible light wavelength band; an image sensor (132) that receives light transmitted through the imaging optical system (100) and acquires an image; and a light amount adjustment optical element that attenuates the light amount of near-infrared light and/or the light amount of visible light being transmitted through the imaging optical system (100). The light amount adjustment optical element adjusts the light amount balance between the light amount of near-infrared light and the light amount of visible light received by the image sensor (132).
