  • Patent number: 10755068
    Abstract: A fingerprint registration method and an electronic device using the same are provided. The fingerprint registration method includes the following steps: sequentially obtaining a plurality of swipe frames of a fingerprint by a fingerprint sensor; sequentially analyzing the swipe frames by a processor to obtain a plurality of feature points; sequentially merging the feature points of the swipe frames into pre-registration data by the processor; sequentially updating a completion area displayed on a user interface by the processor according to relative position relationships of the feature points of the swipe frames; and determining whether the pre-registration data satisfies a preset completion condition by the processor, so as to determine whether to end the fingerprint registration.

  • Publication number: 20160191804
    Abstract: Methods and systems for displaying data for use in an electronic device are provided. First, an image corresponding to at least one specific object is captured by an image capture unit. When the distance between the electronic device and the specific object has changed or the presentation manner of the specific object in the display unit has changed, first data is displayed via the display unit.

  • Patent number: 8285119
    Abstract: A method for playing digital images is disclosed. The method is applied to a disc player that is electrically connected to a computer, comprises the steps of: reading a disc; judging if the disc has DVD video data; judging that the disc player is in a play mode or in a non-play mode, when the disc has the DVD video data; reading the DVD video data, when the disc player is in the player mode; judging if the read DVD video data are correct; and continuing reading the DVD video data, when the DVD video data are incorrect, wherein when a time for the continuing reading exceeds a pre-set time or self-set terms, the incorrect DVD video data are outputted.
