Abstract: An apparatus and a method for displaying a shortcut object in a locked electronic device are provided. A method for controlling a lock function of the electronic device includes detecting a touch input for displaying at least one shortcut object list in a lock screen, displaying a preset shortcut object list according to the detected touch input in a lock mode, selecting at least one shortcut object of the shortcut object list, and executing an application corresponding the selected shortcut object.

Abstract: A method and an apparatus for magnifying or demagnifying a display in an electronic device are provided. A method for controlling display includes detecting at least one first touch, determining a first region according to the at least one first touch, determining whether an area of the first region changes, when the area of the first region is maintained, determining whether the first touch point resides in a display control region, and when the first touch point resides in the display control region, magnifying or demagnifying a display by considering a location change of the first touch point.

Abstract: A method and an apparatus for navigating content larger than a display screen of a terminal using a pointing device are provided. The method includes acquiring, when a pointing position is changed on a screen partially displaying a content that is larger than the screen, a current pointing position by tracking the change of the pointing position, comparing an X axis displacement and a Y axis displacement from an initial pointing position as a starting position to the current pointing position with a predefined X axis threshold value and Y axis threshold value, respectively, determining a movement direction as one of an X axis, a Y axis, and an XY (diagonal) axis directions based on the comparison result, and scrolling the content in the movement direction to display an off-screen part of the content.

Abstract: Disclosed herein are a content reproducing apparatus to display a content image and a menu image on a display device, and a control method thereof. The menu image is generated based on a support capability of the display device. Therefore, when the content image and the menu image are alternately displayed, screen flickering may be prevented from occurring due to a change in image format. Also, a support capability of each constituent element may be notified to the user as guide information, and the content image may be output after user confirmation.
