  • Electronic device and operating method for displaying an image including an imperceivable region
    Patent number: 10032404
    Abstract: 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.
    Type: Grant

  • 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
    Patent number: 9235746
    Abstract: 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.
