  • Method of device unlocking and device utilizing the same
    Patent number: 10977357
    Abstract: A device unlocking method. The method shows challenging icons in challenging rounds and traces user pupils. The method requires a right user to have his pupil movement conform to a challenging icon through the challenging rounds. A device unlocks when a combined moving vector representing the pupil movement passes the challenging rounds and matches an unlocking condition.
    Type: Grant

  • Automatic focusing method and automatic focusing system
    Patent number: 10257405
    Abstract: An automatic focus method includes: catching an image data in a focus area; calculating the image data to get a contrast value curve via a contrast value algorithm; obtaining a contrast weight of each contrast value; calculating an adapted contrast value by multiplying the contrast value to the contrast weight; and adapting the focus according to the adapted contrast value curve. An automatic focus system using the automatic focus method is further disclosed.
