1. An electronic device comprising:
a frame comprising a first region and a second region;
a window member supported by the frame;
a waveguide formed in at least a partial region of the window member;
a support member connected to the frame;
a display configured to project an image onto the window member through the waveguide, the image includes at least one augmented reality image; and
a camera disposed in the second region of the frame to capture a portion of a user's eye,
wherein the camera comprises:
a substrate and an image sensor disposed on the substrate,
a protection glass disposed on the image sensor, and
a lens barrel disposed on the protection glass and having a plurality of lenses embedded therein, the plurality of lenses including a nearest lens that is closest to the image sensor and a furthest lens that is furthest from the image sensor,
wherein an area of the substrate is equal to or smaller than an area of the image sensor,
wherein the camera is inserted into a camera hole formed through a support disposed in the second region of the frame,
wherein the support is formed to be in contact with the user's nose while the electronic device is worn by the user, and
wherein the camera is configured such that a ratio of a back focal length (BFL) to an optical total track length (OTTL) is 0.3 to 0.5,
wherein the BFL is a distance from a focal point to a surface of the nearest lens closest to the image sensor, and
wherein the OTTL is a distance from the focal point to a surface of the furthest lens that is closest to the image sensor.
