Abstract: When a three-dimensional image of a specific subject is acquired by means of an infrared camera and an external light (for example, external light such as sunlight at the time of outdoor photography) having a relatively large intensity exists, it is difficult to acquire the image. To this end, the present invention proposes an electronic device for reducing a current peak by adaptively changing optical power and an exposure time of an infrared camera according to the intensity of external light.
