1. A multi-luminosity image acquiring device comprising:
a camera unit configured to shoot a predetermined subject and acquire an image;
a lighting unit around the camera unit, the lighting unit including a first infrared lamp configured to modulate and emit infrared light depending on a distance from the subject, and a second infrared lamp configured to modulate and emit infrared light depending on an illuminance environment;
an optical filter unit on a front surface of the camera unit and configured to adjust a transmission amount of light incident on the camera unit;
a lamp controller configured to control the first infrared lamp to modulate the infrared light based on the distance from the subject;
a luminosity multiplexing unit configured to generate an optical multiplexing signal that modulates the infrared light of the second infrared lamp and controls a transmittance of the optical filter unit based on the illuminance environment; and
an image processing unit configured to fuse and process multiple images.
