A display device includes a display configured to output a screen image along a first direction, and a lens assembly including at least three lenses arranged sequentially along an optical axis and configured to focus or guide the screen output from the display in a predetermined direction/predetermined position. The lens assembly may be configured to reflect the screen output from the display at least twice between a first lens disposed farthest from the display and an nlens disposed closest to the display. The display may be disposed to be movable in a direction crossing the first direction or the optical axis. The display device satisfies [Conditional expression 1: 0.02<=MD/DSP<=0.2] regarding the diagonal length DSP of the display and the distance MD from the optical axis to the center of the display which is measured along a direction perpendicular to the optical axis.

Display device and electronic device including same

A camera module includes: a first refractive member configured to reflect or refract light that is incident on the first refractive member in a first direction, in a second direction intersecting the first direction; a second refractive member configured to reflect or refract the light that is reflected or refracted by the first refractive member and is incident on the second refractive member in the second direction, in a third direction intersecting the second direction; an image sensor configured to detect the light that is reflected or refracted by the second refractive member and is incident on the image sensor in the third direction; and at least one optical member provided between the first refractive member and the second refractive member, wherein the at least one optical member is configured to block the light that is reflected or refracted by the first refractive member from being incident on the image sensor, and to guide the light that is reflected or refracted by the first refractive member to be incident on the second refractive member in the second direction.

Camera module including folded optics

An electronic device performing a method of tracking a user's gaze of an electronic device and outputting an augmented reality (AR) image is provided. The metho includes outputting a first light which is a structured light at a first time point toward the user's eyes, outputting a second light at a second time point toward the user's eyes, acquiring a first image in response to the output of the first light at the first time point, acquiring a second image in response to the output of the second light at the second time point, synthesizing the first image and the second image to create a third image, calculating first coordinate values, which are coordinate values of pupils of the user's eyes on the basis of the third image; and detecting a gaze direction on the basis of the first coordinate values.

Electronic device and method thereof for tracking user gaze and providing augmented reality service

A wearable electronic device with a display is provided. The wearable electronic device includes: a stereo camera configured to detect infrared light, a self-luminous display including a plurality of visible light pixels configured to output visible light corresponding to a virtual object image and a plurality of infrared pixels configured to output infrared light, an optical waveguide configured to output the virtual object image by adjusting a path of the visible light, a first control circuit configured to supply driving power and a control signal to the self-luminous display, and a second control circuit configured to supply driving power and a control signal to the stereo camera. The optical waveguide includes a half mirror configured to output reflected infrared light and transmitted infrared light in response to the output infrared light.

Wearable electronic device with display

An electronic device is provided. The electronic device includes a light source module, a display module including at least one layer, a camera module, and a processor operatively connected to the light source module, the display module, and the camera module. The processor may emit light through the light source module along a waveguide formed in the at least one layer of the display module, may use the camera module to detect, based on at least one pattern structure formed in the waveguide, at least a part of the light, which has been reflected from a user's eyeball, and may track the movement of the user's eyeball, based on the detected light.

Method and electronic device for tracking eye

Augmented reality (AR) glass is provided. The AR glass includes a first light source which emits display light for displaying an AR image, an eye tracking (ET) sensor for detecting reflected light reflected from the eye of a user, glass, which includes a display waveguide for guiding the display light, emitted from the first light source, to a display area of a see-through display, and an ET waveguide for guiding the reflected light to the ET sensor, and a processor electrically connected to the first light source and the ET sensor, wherein the processor controls the first light source so as to emit the display light, and tracks, through the ET sensor, the gaze of the user on the basis of the detected reflected light.
