Embodiment Construction

[0063] The invention provides a screen lighting control method, device and electronic equipment to solve the technical problem of long time delay in the detection method of raising the hand to turn on the screen in the prior art.

[0064] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0065] First obtain the waveform of the acceleration value of the electronic device within the first preset time period; then match the waveform of the acceleration value with the preset waveform, and the preset waveform is when the motion state of the electronic device meets the bright screen condition The corresponding waveform; finally, based on the matching result, it is determined whether to control the screen of the electronic device to enter a lighting state. That is to say, instead of judging whether the motion state of the electronic device satisfies the bright-screen condition ...

Abstract

The invention relates to the electronic technical field, and especially relates to a screen lightening control method, device and electronic equipment, thus solving the technical problems that an existing lift-hand lightening detection mode is long in time delay; the novel method comprises the following steps: firstly obtaining an acceleration speed value waveform of the electronic equipment in the first preset time period; matching the acceleration speed value waveform with a preset waveform, wherein the preset waveform is the waveform corresponding to a condition in which the electronic equipment motion state satisfies the lightening conditions; determining whether to control the electronic equipment screen to enter the lightening state or not according to the matching result, i.e., a difference algorithm is not used to determine whether the electronic equipment motion state satisfies with the lightening conditions or not, yet the electronic equipment acceleration speed value waveform is compared with the preset waveform, thus determining whether the electronic equipment motion state satisfies with the lightening conditions or not. The novel screen lightening control method has fewer limits on sampling spot numbers, thus realizing the technical effect of reducing time delay.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a screen lighting control method, device and electronic equipment. Background technique [0002] In the prior art, using the built-in acceleration sensor on the smart watch, it can automatically sense the action of the user raising his hand to look at the smart watch, and then light up the screen without the user's button operation, and can also automatically sense the user's hand down action, and then turn off the screen. Backlight, saving power consumption. [0003] Under normal circumstances, the action of raising one's hand to check a smart watch can be decomposed into two continuous actions: raising hand action + static action. In the existing algorithm of raising hand to brighten the screen, the method of calculating the difference between two adjacent sample points is often used. To determine the user's action on the smart watch, this method has the technical ...
