Abstract

The invention belongs to the field of control technologies, and provides a method and device for controlling rotation of a mobile terminal camera and a mobile terminal. The mobile terminal comprises a digital Hall sensor. The method includes the steps that control information of the camera is obtained, wherein the control information of the camera includes the rotating direction of the camera; according to the control information, the camera is controlled to rotate in the rotation direction; in the rotation process of the camera, the output value of the digital Hall sensor is obtained, and the angle, corresponding to the output value, of the camera is obtained according to the output value; when the angle of the camera reaches a preset threshold value, a preset angle corresponding to the preset threshold value is obtained, and the camera is controlled to rotate by the preset angle in the rotation direction from the current position. By the adoption of the method, the camera is controlled to accurately rotate to a target angle from any initial angle, motor idling does not exist, and the problems that through an existing mode, because a motor idles, power is consumed, and heat is generated are solved.

Description

technical field

[0001] The invention belongs to the technical field of control, and in particular relates to a method, a device and a mobile terminal for controlling the rotation of a camera of a mobile terminal. Background technique

[0002] Most of the existing mobile terminals (such as mobile phones, tablet computers, etc.) are equipped with relatively high-performance cameras, and users can rotate and control the cameras so as to take pictures and record videos.

[0003] The existing method of manually controlling the rotation of the camera can manually rotate the camera, but the rotation angle of the camera cannot be known. In view of the shortcomings of the existing methods of manually controlling the rotation of the camera, some manufacturers have also proposed mobile terminals equipped with a rotating camera. By setting a rotating mechanism with an electric motor, the rotation angle of the camera can be controlled electrically. However, because the way the camera ro...
