Abstract

A rotating method of an image on a mobile device includes detecting a first included angle between a reference direction of the mobile device and a gravity direction, and a first rotational direction that the reference direction of the mobile device has been rotated relative to the gravity direction; selectively generating a first rotating signal according to the first included angle; detecting a second included angle between a reference direction of a user's face and the gravity direction, and a second rotational direction that the reference direction of the user's face has been rotated relative to the gravity direction; selectively generating a second rotating signal according to the second included angle; and rotating the image on the mobile device in a rotational direction opposite to the first rotational direction and/or identical to the second rotational direction.

selectively generating a first rotating signal according to the first included angle;
detecting, through a face recognizer, a second included angle between a reference direction of a user's face and the gravity direction, and detecting a second rotational direction that the reference direction of the user's face has been rotated relative to the gravity direction, wherein the second included angle is detected, regardless of the first included angle, as an angle between the reference direction of the user's face and the gravity direction;
selectively generating a second rotating signal according to the second included angle simultaneously with generation of the first rotating signal; and
determining an image rotating direction of the image on the mobile device according to an additive combination of both the first rotating signal and the second rotating signal.

rotating the image on the mobile device in a rotational direction opposite to the first rotational direction or identical to the second rotational direction in a condition that one of the first rotating signal and the second rotating signal is generated, and the other one of the first rotating signal and second rotating signal is not generated.

3. The rotating method as claimed in claim 1 , wherein the step of determining the image rotating direction of the image on the mobile device comprises:
not rotating the image on the mobile device in a condition that both of the first rotating signal and the second rotating signal are not generated.
