Abstract:
A method and apparatus for generating a dewarped document using a document image captured using a camera are provided. The method includes obtaining the document image captures using the camera, extracting text lines from the document image captured using the camera, determining a projection formula to convert positions of respective points constituting the extracted text lines to coordinates projected on a plane of the dewarped document, determining a target function used to calculate a difference between text lines projected on the place of the dewarped document using the projection formula and real text lines, calculating parameters that minimize the target function, and converting the document image to the dewarped document by substituting the calculated parameters into the projection formula.

Abstract:
A touch screen is disclosed. The touch screen comprises: a display panel displaying an image; and a touch panel detecting a touch of a user, wherein the touch panel comprises a 2D/3D touch pattern layer having a 2D touch electrode pattern and a 3D touch electrode pattern disposed on both sides of a substrate.
Abstract:
A display apparatus is provided. The display apparatus includes a display and a controller. The display is configured to display an image and comprises a touch sensor for touch input within an assigned sensing section. The controller is configured to perform an operation corresponding to the touch input sensed within the sensing section, and to control the touch sensor to adjust the sensing section based on conditions for adjusting the sensing section. With this, the display apparatus and a control method thereof which can efficiently sense, without lowering the speed of sensing, a touch input based on a plurality of pens or fingers is provided.
Abstract:
A method of styling content on a touch screen device is provided. The method includes receiving a user's input with respect to an attribute item of a stroke-based object, receiving a user's touch input with respect to a region indicating the stroke-based object on a touch screen, and changing an attribute value of the stroke-based object based on the attribute item of the stroke-based object and the received user's touch input.
Abstract:
A display apparatus capable of being touched plural times by a single user or being used by a plurality of users is provided. The display apparatus includes: a display; a sensor sensing a user touch on the display; and a processor configured to execute a writing function corresponding to a first touch when the first touch is sensed through the sensor and executing a function corresponding to a second touch of a user at a coordinate value at which the second touch is sensed in response to the second touch when the second touch is sensed in a predetermined range of the first touch based on a coordinate value at which the first touch is sensed during a period in which the first touch is input.
Abstract:
A reconfigurable mobile device is provided. The reconfigurable mobile device includes a first body, a second body that is disposed at a side of the first body and is movable with respect to the first body, a multistage supporter that is provided between the first body and the second body and comprises at least two supporting members that are inserted and received in at least one of the first body and the second body according to movement of the first body and the second body, a screen that is provided in the multistage supporter and is wound or unwound according to the movement of the first body and the second body, and a projector that is provided in at least one of the first body and the second body and configured to project an image toward the screen.
Abstract:
A method of managing an application having a background module is provided. The method includes operations of determining a first background stop time and stopping the execution of the background module of the application during the first background stop time, wherein the first background stop time is a time period between a point of time when execution of the application was stopped and a first point of time.
Abstract:
A multi display apparatus includes a first body comprising a first display, a second body comprising a second display, a hinge to connect the first and second bodies to each other, a first imaging unit provided on the first body, a second imaging unit provided on the second body, and a controller to recognize a user's gesture using a plurality of images photographed at the first and second imaging units, and perform a corresponding control operation in response to the recognized user gesture. The controller recognizes the user's gesture using a movement of a user object within recognition ranges of the respective imaging units. As a result, the operation of the multi display apparatus can be controlled more easily and conveniently.
