Abstract: Provided are an augmented reality (AR) device for improving the accuracy of position information of a joint of a hand obtained through vision-based hand tracking technology by using a sensor measurement value obtained from an external device, and an operating method thereof. According to an embodiment of the disclosure, the AR device may update a three-dimensional position coordinate value of a joint of a hand by correcting a three-dimensional position coordinate value of the joint of the hand obtained from a plurality of image frames obtained through a camera by using a measurement value of an inertial measurement unit (IMU) sensor obtained from a wearable device.

Abstract: An electronic device performs a method of obtaining Three-Dimensional (3D) skeleton data of an object obtained by using a first camera and a second camera. The method includes: obtaining a first image using the first camera and obtaining a second image using the second camera; obtaining, from the first image, a first Region Of Interest (ROI) comprising the object; obtaining, from the first ROI, first skeleton data comprising at least one keypoint of the object; obtaining a second ROI from the second image, based on the first skeleton data and information about a relative position between the first camera and the second camera; obtaining, from the second ROI, second skeleton data comprising at least one keypoint of the object; and obtaining 3D skeleton data of the object, based on the first skeleton data and the second skeleton data.

Abstract: A device and method of operating the device for automatically creating photos or videos of a certain moment are provided. The method includes obtaining a plurality of image frames sequentially captured through a camera for a preset time interval; detecting at least one image frame among the plurality of image frames in which a main object corresponding to a preset main object or an action of the main object corresponding to a preset action is recognized; determining a type of composition of the at least one image frame; cropping a region including the main object from the at least one image frame based on placement of objects in the at least one image frame and the determined type of composition; and creating the photo using the cropped region.
