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.
