WIPO Patent Application WO/2023/085475
Kind Code:
A1
Abstract:
The present invention relates to a multi-band image capturing apparatus and method for capturing multi-band images, including visible and infrared images, by using a light adjustment filter, the apparatus comprising: a camera unit for acquiring multi-band images including visible and infrared images; a lighting unit for emitting infrared rays; an optical filter unit which includes a hot mirror filter region and an infrared transmission filter region, and which selectively transmits visible light therethrough by moving and arranging the hot mirror filter region onto an optical path or transmits infrared rays therethrough by moving and arranging the infrared transmission filter region onto the optical path; and a light adjustment control unit for controlling the camera unit, the lighting unit and the optical filter unit, wherein the light adjustment control unit determines a light level on the basis of the light intensity of infrared rays in an photography environment so as to control the lighting unit so that infrared rays corresponding to the determined light level are emitted, and control the optical filter unit so that the hot mirror filter region or the infrared transmitting filter region is moved and arranged onto the optical path in correspondence to a light wavelength band image to be acquired by the camera unit.
