Abstract
We offer a method of adjusting a camera top-down angle for a mobile terminal. The method involves automatically detecting whether a mobile terminal camera is set to top-down shooting mode based on the z-axis of the mobile terminal acceleration sensor, automatically adjusting a camera orientation by means of a mobile terminal gyroscope sensor when the camera is set to top-down shooting mode, and displaying the camera orientation at the mobile terminal so that a user recognizes the camera orientation and manually adjusts it when it does not correspond to the shooting orientation.
