Camera rotation control method applied to mobile terminal and mobile terminal

Abstract

The invention discloses a camera rotation control method applied to a mobile terminal and the mobile terminal. The mobile terminal comprises a terminal body and a camera device. The camera device can rotate relative to the terminal body and comprises a magnet. The position, corresponding to the camera device, of the terminal body is provided with a digital Hall sensor. The camera rotation control method includes: receiving an instruction to rotate the camera, in which a target angle is carried; detecting a value of the digital Hall sensor; according to the detected value of the digital Hall sensor as well as a table of correspondence between the value of the digital Hall sensor and an angle of the camera device, determining a current angle of the camera device; calculating an angle to be finished; rotating the camera device to the angle to be finished, through a motor. The camera rotation control method and the mobile terminal according to the technical scheme have the advantages that optionally angular rotation is allowed for the camera, and the service life of the motor used for controlling rotation of the camera is prolonged.

Description

technical field [0001] The present invention relates to the field of photography, in particular to a camera rotation control method applied to a mobile terminal and the mobile terminal. Background technique [0002] With the development of science and technology, the functions of mobile terminals (such as mobile phones, tablet computers, etc.) are becoming more and more rich and powerful. At present, most mobile terminals are equipped with high-performance cameras so that users can use mobile terminals to take pictures or video . [0003] For most mobile terminals, what is equipped with is a fixed camera, that is, the camera is fixed on the mobile terminal, and the fixed camera is divided into a rear camera (that is, a camera installed on the back of the mobile terminal) and a front camera (that is, a camera installed There are two types of cameras on the front of the mobile terminal. This fixed camera is relatively simple in use. During the shooting process, the user often...

Problems solved by technology

[0004] However, at present, mobile terminals with rotating cameras can only control the rotation of the camera to two fixed positions (such as a position parallel to the screen of the mobile terminal and a position parallel to the back of the mobile terminal), which are used to switch between the front and back of the camera, but cannot Control the camera to rotate to any desired position. In addition, in order to realize the front-to-back switch of the camera, the mobile terminal needs to rotate the camera to the maximum angle to ensure that the front-to-back switch can be successful. The problem that the motor is still idling, which affects the service life of the motor
