Embodiment 1
[0021] figure 1 The screen rotation implementation process provided by the first embodiment of the present invention is shown, and the process is described in detail as follows:
[0022] Step S101, acquiring position information of two eyes.
[0023] The manner in which the mobile terminal obtains the position information of the two eyes may be: using a camera or a video camera of the mobile terminal to obtain the information.
[0024] When using a camera or a video camera to obtain a face picture (for example, using a front camera in a mobile terminal to obtain a face picture), use image processing technology to find two eyes from the face picture, and use the plane coordinate system Position information of the two eyes is determined.
[0025] The position information includes but not limited to coordinate information of two eyes.
[0026] Step S102, according to the position information, obtain the normal line of sight of the two eyes.
[0055] figure 2 The composition structure of the screen rotation device provided by the second embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.
[0056] The device based on screen rotation can be a software unit, a hardware unit, or a combination of software and hardware running in each terminal device (such as a tablet computer, a smart phone), or it can be integrated into the terminal device as an independent pendant or run in the application system of the terminal device.
[0057] This embodiment provides a screen rotation device, which may include a position information acquisition unit 21, a front view unit 22, and a display adjustment unit 23, wherein each functional unit is described in detail as follows:
[0058] The location information acquiring unit 21 is configured to acquire the location information of the two eyes.
[0059] The manner in which the ...

Abstract
The invention is applicable to the field of mobile terminals and provides a screen rotating method, a screen rotating device and a mobile terminal. The screen rotating method includes acquiring position information of two eyes, obtaining a forward sight line the two eyes are located according to the position information, and adjusting the display direction of a screen display picture according to the forward sight line. When in use of the mobile terminal, the screen display picture of the mobile terminal is adjusted to the direction of the forward sight line of the eyes of the user so as to be convenient for browsing by the user and prevent eye diseases.
Description
technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a screen rotation method, device and mobile terminal. Background technique [0002] In recent years, gravity sensors have been widely used in mobile terminals. The application of the gravity sensor in the mobile terminal is: the screen display screen of the mobile terminal is adjusted to the screen angle suitable for the user to watch at any time as the direction of the mobile terminal’s gravity changes; however, there are the following problems in the application: when the mobile terminal When the terminal is moving in other non-gravity acceleration directions, the screen display cannot be accurately rotated to the angle of viewing the screen display in the direction of gravity. [0003] The screen display direction suitable for mobile terminal users does not necessarily have an absolute relationship with the direction of gravity. For example, when the user is lying ...
