Method for preventing camera idling and terminal

Abstract

The invention discloses a method for preventing camera idling and a terminal. The method for preventing the camera idling includes that receiving a camera rotating command, and starting a camera to rotate in a single direction in a uniform speed; acquiring Hall values from a digital Hall sensor on the terminal according to a fixed time interval, and calculating the difference between the current acquired Hall value and the previous acquired Hall value; if the continuous times of the phenomenon that the difference between the current acquired Hall value and the previous acquired Hall value is less than or equal to a first preset value arrives at preset lasting times, stopping the rotation of the camera. The method for preventing the camera idling is capable of preventing the camera idling, the electrical resource of the terminal is saved, the mechanical loss of an electric motor in the rotating camera is reduced, and accordingly the service life of the rotating function of the rotating camera is increased.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method for preventing idling of a camera and a terminal. Background technique [0002] With the continuous development of communication technology, the functions of the terminal are becoming more and more abundant, wherein, the camera function provided by the terminal is very popular among users. At present, many terminal manufacturers have launched electric rotating cameras, such as Figure 6 The schematic diagram of the structure of a rotatable camera on a terminal is shown. The principle of the electric rotatable camera is: a tiny electric motor is built into the camera to make the camera rotate. In addition, a magnet is set on the camera. There is also a digital Hall sensor on the body corresponding to the magnet on the camera. When the camera rotates, the angle of the camera changes, and the distance between the magnet on the camera and the digital Hall sensor al...

Problems solved by technology

[0003] However, the magnetic field is easily interfered by the external electromagnetic field. When the terminal is in different electromagnetic fields, even if the distance between the Hall sensor and the magnet is the same, the Hall value will be different, making the angle recognition of the camera inaccurate. When the camera has actually rotated to At the maximum angle, but the terminal does not recognize it, the electric motor is still rotating, causing the problem of motor idling, wasting terminal power resources, and deteriorating the mechanical performance of the motor
