An electronic device having a display function and operating method therefor are provided, which display a transformed image based on image processing information, in order to reduce current normally consumed in displaying regions of an original image that are not perceivable to a user. The method includes obtaining an image to be displayed; determining image processing information of the electronic device; transforming the image based on the image processing information; and displaying the transformed image.

Electronic device and operating method for displaying an image including an imperceivable region

A method of controlling a screen brightness in a user device includes determining an illumination when a display unit is turned on, determining an optimal brightness according to the illumination and displaying according to the optimal brightness during an illumination change, determining an illumination when the current optimal brightness reaches a threshold, and determining an optimal brightness in the determined illumination and controlling a screen display according to the optimal brightness.

Method and apparatus for controlling screen brightness corresponding to variation of illumination

A method for performing user authentication by using a fingerprint in an electronic device is provided. The method includes obtaining fingerprint image and fingerprint position information corresponding to an area of the user's finger, comparing the fingerprint image obtained by using fingerprint position information with a pre-registered fingerprint image corresponding to the position of the area to thereby perform the user authentication, and pairing the fingerprint image corresponding to the area of the user's finger with the fingerprint position information to be thereby stored in the memory.

Electronic device including fingerprint identification sensor, methods for performing user authentication and registering user's fingerprint in electronic device including fingerprint identification sensor, and recording medium recording program for executing the methods
