Screen picture rotation method and system

Abstract

A screen picture rotation method comprises a first detection step, a second detection step and a control step. The first detection step includes that during the operation from the starting to the closing of an electronic device, whether a screen of the electronic device is laid horizontally is detected in real time through an electronic level meter in the electronic device; the second detection step includes when the screen is detected to be horizontally laid continuously, and the rotation direction and the angle of the screen are detected in real time through an electronic orienting device in the electronic device; and the control step includes that when the detected rotation direction of the screen reaches a preset switching value, a picture displayed by the screen is controlled to rotate by 90 degrees relative to the screen to the direction opposite to the rotation direction. The invention further provides a screen picture rotation system. According to the screen picture rotation method and the system, automatic switchover between horizontal screen display and vertical screen display of the screen can be achieved in the condition that the screen is horizontally laid.

Description

technical field [0001] The invention relates to a screen image rotation method and system, in particular to a screen image rotation method and system in a horizontally placed state. Background technique [0002] At present, various portable electronic devices on the market, such as tablet computers, mobile phones, digital cameras, etc., mostly have gravity sensors, which can sense the acceleration of gravity of the carrier. Through the gravity sensor, the electronic device can detect the rotation direction and angle of the screen, and automatically switch the screen between horizontal screen display and vertical screen display according to the placement state of the electronic device, which is convenient for users to watch the screen. [0003] However, when the screen of the electronic device is placed horizontally, that is, the plane on which the screen is located is perpendicular to the direction of gravity, such as when the electronic device is placed on a table, the elec...

Problems solved by technology

[0003] However, when the screen of the electronic device is placed horizontally, that is, the plane on which the screen is located is perpendicular to the direction of gravity, such as when the electronic device is placed on a table, the electronic device will not be able to detect the rotation of the screen through the acceleration of gravity sensed by the gravity sensor. direction and angle of

Therefore, in this case, no matter how the user rotates the screen, it is impossible to automatically switch the screen between the horizontal screen display and the vertical screen display, which brings a bad experience to the user
