The method includes obtaining, at the second device, a display screen displayed on the first device and information related to the display screen according to a screen display request regarding the first device, determining, at the second device, an additional screen based on the display screen on the first device and the information related to the display screen, and displaying the additional screen near the display screen on the first device.

Abstract: An electronic device, a method thereof, a non-transitory computer-readable recording medium, and a chipset are disclosed. The electronic device includes a sensor module including a plurality of sensor arrays for scanning a target object located in a predetermined vicinity of the electronic device; and a control module configured to determine a direction in which the target object is located, based on a first signal that the sensor module outputs with respect to the target object, and scan the target object located in the determined direction, wherein the sensor arrays are spaced apart from each other.

Abstract: An image providing method includes displaying a first image, the first image including an object and a background; receiving a user input selecting the object or the background as a region of interest; acquiring first identification information associated with the region of interest based on first attribute information of the first image; acquiring a second image from a target image, the second image including second identification information, the second identification information being the same as the first identification information; and generating an effect image based on at least one of the first image and the second image.

Abstract: A knowledge sharing system includes a social network service (SNS) providing server that stores relationship information between a first user and a second user. The knowledge sharing system includes a knowledge sharing service providing server including a query data management unit that stores query data when the query data is transmitted from a first terminal of the first user and stores a query sharing request in association with the query data when the query sharing request is transmitted from a second terminal of the second user, and in the storing of the query sharing request, the query data management unit matches the query sharing request with the query data; and a query data providing unit that provides the query data matched with the query sharing request to a third terminal of a third user, where the third user is connected with the second user in the SNS platform.

Abstract: A digital apparatus is provided. The digital apparatus includes an image acquisition unit configured to acquire an image of a user and a controller configured to recognize a hand shape in the acquired image of the user and to perform a function corresponding to the recognized hand shape.

Abstract: A method and apparatus for processing an image, whereby a 3-dimensional (3D) hand model corresponding to a hand image obtained may be generated by capturing an image of a hand of a person are provided. The method includes preparing a 3D hand model database, receiving a 2-dimensional (2D) hand image obtained by capturing an image of a first hand, and detecting a first 3D hand model corresponding to the 2D hand image by using the 3D hand model database.

Abstract: A method and apparatus are provided for segmenting an object in an image. The method includes obtaining a first image including the object; receiving an input signal including information about a predetermined position in the first image; selecting at least one pixel included in the first image, based on the position information; generating a second image by dividing the first image into several areas, using the selected at least one pixel; and segmenting the object in the first image by using the first image and the second image.

Abstract: A user interface for a movement between pages having a laminated structure in a portable device is provided. A method of searching for a page in a three dimensional manner in a portable device includes overlappingly displaying a plurality of pages in three dimensions; detecting a distance between the portable device and a user input means; sequentially moving and displaying the plurality of pages according to the detected distance; and when a movement of the user input means for selecting a page is detected, displaying the selected page. As a user brings a user input means close to a front surface of the portable device, the pages having the laminated structure are sequentially moved and displayed one by one, starting from a page displayed on the front. The user can identify the pages and select a desired page by making a gesture for selecting a shown page.

Abstract: A method and apparatus for controlling an operation of a camera that allows a user to conveniently control a camera apparatus according to a gesture of a subject input through a lens of a camera, and the camera apparatus are provided. The method includes receiving an image input through a camera lens; generating an image frame; detecting a motion of a subject included in the image frame by comparing the image frame with at least one previous frame stored before the image frame is generated; determining whether the motion of the subject is a User Interface (UI) gesture; and performing, if the motion is the UI gesture, an operation corresponding to the UI gesture.

Abstract: A camera apparatus and method enabling a user to conveniently control an operation of the camera apparatus according to a gesture of a subject for photography input through a lens of a camera, and a method of controlling the camera apparatus are provided. The method includes generating a current frame by receiving an image input through a camera; comparing the current frame and one or more previous frames stored before the current frame and detecting a gesture of a subject for photography included in the current frame and the one or more previous frames; determining whether the gesture is a gesture UI; and when the gesture is the gesture UI, executing an operation corresponding to the gesture UI.
