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.
Claims16
A method of adjusting a camera top-down angle of a mobile terminal that involves the following:
- 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 and
- automatically adjusting a camera orientation using a mobile terminal gyroscope sensor when the camera is set to top-down shooting mode.
A method of adjusting a camera top-down angle of a mobile terminal that involves the following:
- automatically detecting whether a mobile terminal camera is set to top-down shooting mode based on the z-axis of a mobile terminal acceleration sensor;
- and
- displaying a mobile terminal camera orientation such that a user recognizes the camera orientation and manually adjusts it when it does not correspond to the shooting orientation.

A camera top-down angle-adjusting system of a mobile terminal that involves:
- an automatic shooting-mode detection unit adapted to detect automatically whether a mobile terminal camera is set to top-down shooting mode based on the z-axis of a mobile terminal acceleration sensor;
- an automatic adjustment unit adapted to adjust automatically a camera orientation by means of a mobile terminal gyroscope sensor when the camera is set to top-down shooting mode;
- and
- a manual adjustment unit adapted to display a mobile terminal camera orientation such that a user intuitively recognizes the camera orientation and manually adjusts it when it does not correspond to the shooting orientation.
