Abstract: A decorative flexible-electronic-film structure includes a mechanical member and a flexible electronic molded film. The mechanical member includes a mainboard part and a curved clamping part, and an accommodating slot is formed on the mainboard part. The flexible electronic molded film includes a body part, a side hook part and an electronic component, an inner surface of the body part faces the mainboard part, the electronic component is disposed on the inner surface and corresponds to the accommodating slot, and the side hook part is formed on the periphery of the body part and is curved. The flexible electronic molded film is assembled onto the mechanical member, with the body part overlapping the mainboard part, the electronic component being accommodated in the accommodating slot, and the side hook part being buckled to the clamping part. A method of forming the decorative flexible-electronic-film structure is also provided.

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.

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.
