Document Type and Number:
WIPO Patent Application WO/2021/034002
Kind Code:
A1
Abstract:
The present invention relates to a device and a method for acquiring multi-luminosity images, wherein images having multiple luminosities in visible-ray and infrared wavelength domains can be captured and synthesized by using optical filter transmittance adjustment. The device may comprise: a camera unit for photographing a predetermined subject and acquiring images thereof; a lighting unit disposed on the periphery of the camera unit so as to emit infrared light; an optical filter unit disposed on the front surface of at least one of the camera unit and the lighting unit so as to adjust the amount of transmission of light directed to the camera unit or the amount of emission of infrared light emitted from the lighting unit; a luminosity multiplexing unit for producing a light multiplexing signal so as to control the transmittance of the optical filter unit on the basis of the distance from the subject and the photography environment; and an image processing unit for synthesizing and processing multiple captured images.
