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.

Abstract: The present invention relates to a method and an apparatus for acquiring information by capturing an eye or an area around an eye. A wearable electronic device according to various embodiments of the present invention may comprise: a light source; at least one lens; an optical surface disposed on a first side of the at least one lens; and a camera for receiving, through the at least one lens and the optical surface, light output from the light source and scattered by a subject located on a second side of the at least one lens.

Abstract: A projector includes a light source that emits a light beam, an illumination lens unit, a display device, a projection lens unit, a field lens, and a reflection member. The illumination lens unit shapes and focuses the light beam into an illumination light beam. The display device modulates the illumination light beam and forms an image. The projection lens unit projects the image on a screen. The field lens has a positive refractive power for focusing the illumination light beam on the display device, a first lens surface on which the illumination light beam is incident, and a second lens surface on which the image formed by the display device is incident. The reflection member changes an illumination light beam path into a direction of the field lens. The first lens surface reflects a portion of the illumination light beam into a path that avoids the projection lens unit.

Abstract: Disclosed is a vapor axial deposition apparatus. The vapor axial deposition apparatus includes a first torch, a growth size detecting unit and a controlling unit. The first torch deposits soot on a distal end of a soot preform aligned with a first axis, and is aligned with a second axis. The growth size detecting unit detects an image including a growing point of the soot preform and an end of the first torch. The controlling unit calculates a distance between the soot preform and the first torch along the second axis from the detected image, and moves the soot preform upward based on the calculated distance.
