Abstract

The invention belongs to the technical field of mobile terminals, and provides a method and device for detecting the rotating angle of a camera and a mobile terminal. The method is applied to the mobile terminal, and the mobile terminal comprises a mobile terminal body, the camera and a rotating type connecting structure. The mobile terminal body comprises a first acceleration sensor, and the rotating type connecting structure comprises a second acceleration sensor. The method comprises the steps of obtaining the output value of the first acceleration sensor, according to the output value, determining the inclination angle of the mobile terminal body, obtaining the output value of the second acceleration sensor, according to the output value, determining the inclination angle of the camera, and according to the inclination angle of the mobile terminal body and the inclination angle of the camera, calculating the rotating angle of the camera. The rotating angle of the camera is detected according to the acceleration sensors, the accuracy and stability of detecting the rotating angle of the camera are improved, and the idling and rotation blocking problems in the rotating process of an existing camera are solved, and the production cost is reduced.

Description

Technical field [0001] The present invention belongs to the technical field of mobile terminals, and in particular relates to a method for detecting a rotation angle of a camera and a device mobile terminal. Background technique [0002] The rotation angle of the current camera is mainly detected by a digital Hall sensor. The digital hall sensor is equipped with a magnetic induction chip, which can sense the magnetic field of the magnet set on the camera. During the rotation, the distance between the magnet and the digital Hall sensor will change. The output value of the digital hall sensor corresponding to different distances is different, and the rotation angle of the camera is obtained through this output value. [0003] However, the magnetic field is easily disturbed by the external environment. If the camera is in an electromagnetic environment, the digital Hall sensor will be interfered by the external magnetic field, and the rotation angle obtained according to the output...
