Abstract
Provided is a night vision output device comprising: an optical pulse output unit for outputting pulsed light at specific periods; a photographing unit having an image sensor for forming a plurality of images by using pulsed light reflected by an external object; a display unit for outputting a final image formed by synthesizing the plurality of images; and a control unit for calculating distance information of an object displayed in each pixel by using data of a brightness ratio for a distance and a brightness ratio for each pixel of the final image, wherein, in one frame, the control unit controls the image sensor such that the image sensor is activated while having different delay times on the basis of an output termination time of the pulsed light.
