Embodiment 1

[0050] figure 1 The first implementation process of the method for controlling the rotation of the camera of the mobile terminal provided by Embodiment 1 of the present invention is shown.

[0051] In this embodiment, the method is applied to a mobile terminal composed of a mobile terminal body 11 and a camera device 12, such as figure 2 shown. The camera device 12 can rotate relative to the mobile terminal body 11, and the camera device 12 is provided with a camera 121 and a magnet 122, and the magnet 122 deviates from the rotation axis of the camera device. The mobile terminal body 11 is provided with a digital Hall sensor 111 at a position opposite to the magnet on the camera device 12, and the distance between the digital Hall sensor 111 and the magnet 122 increases with the distance between the camera device 12 and the magnet 122. 12 rotates, so that the digital Hall sensor 111 can sense the change of the magnetic field caused by the magnet 122 rotating with the camera...

Embodiment 2

[0076] Figure 5 It shows the second implementation process of the method for controlling the rotation of the camera of the mobile terminal provided by the second embodiment of the present invention, and for the convenience of description, only the parts related to the present invention are shown.

[0077] The method is applied to figure 2 The mobile terminal (defining the absolute front position as 180 degrees and the absolute rear position as 0 degrees) and image 3 On the infrared gesture sensor, the method is specifically:

[0078] In step S501, a change trend of an infrared intensity value of an infrared gesture sensor is obtained.

[0079] In step S502, it is judged whether the change trend of the infrared intensity value conforms to a preset change trend.

[0080] If the judgment result is yes, execute step S503; otherwise, execute step S510 without any operation.

[0081] In step S503, the camera control information corresponding to the infrared intensity value ch...

Embodiment 3

[0097] Figure 6 The composition structure of the device for controlling the rotation of the camera of the mobile terminal provided by the third embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0098] The device is used to realize figure 1 and Figure 5 The method for controlling the rotation of the camera of a mobile terminal described in the embodiment. Wherein, the mobile terminal is composed of a mobile terminal body 61 and a camera device 62, such as Figure 7 shown. The camera device 62 can rotate relative to the mobile terminal body 61, and the camera device 62 is provided with a camera and a magnet, and the magnet deviates from the rotation axis of the camera device. The mobile terminal main body 61 is provided with a digital Hall sensor 61 at a position opposite to the magnet on the camera device 62, and the distance between the digital Hall sensor and t...

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...
