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 and infrared lighting strength 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, the lighting unit comprising a first infrared lamp for modulating and emitting infrared light according to the distance from the subject and a second infrared lamp for modulating and emitting infrared light according to the photography environment; an optical filter unit disposed on the front surface of the camera unit so as to adjust the amount of transmission of light directed to the camera unit; a lamp control unit for controlling the first infrared lamp such that infrared light is modulated on the basis of the distance from the subject; a luminosity multiplexing unit for producing a light multiplexing signal so as to control infrared light modulation by the second infrared lamp and the transmittance of the optical filter unit on the basis of the photography environment; and an image processing unit for synthesizing and processing multiple captured images.
