Method and system for detecting ambient light by light sensor of mobile terminal

Abstract

The invention discloses a detection method and system for the environment light by mobile terminal light sensor. The method comprises the following steps: A) using the light sensor of a mobile terminal to detect the light signal of the current environment light at a designated time interval and converting the light signal into current corresponding voltage value; B) accumulating the current voltage value to the stored voltage sum for the current voltage sum; based on the current voltage sum and the accumulation times, obtaining the average voltage value; and C) converting the obtained average voltage value; outputting the corresponding environment light brightness instruction and determining the brightness of the current environment light. According to the invention, through the calculation of the average voltage value of the voltage signal outputted by a photoelectric conversion unit in a period of time in which the brightness of the environment light does not change significantly, the accuracy of environment light detection is improved so that the brightness on the display screen of a mobile terminal can be adjusted instantly, that a user has good visual effect and that the mobile terminal can be energy conserving in a more accurate manner.

Description

technical field [0001] The invention relates to the technical field of mobile terminal optical sensor detection, in particular to a method and system for detecting ambient light by a mobile terminal optical sensor. Background technique [0002] With the development of communication technology, mobile terminals such as mobile phones are used more and more widely. Due to the mobility of the mobile phone, it is used in environments with different brightness. However, the brightness of the traditional mobile phone screen is fixed, so there is a problem: under the brightness of the indoor light, the brightness of the mobile phone screen is appropriate, but Under the outdoor sunlight, the mobile phone screen will be too dark to see clearly, or in a dim environment, the mobile phone screen will appear too bright and too dazzling, causing damage to the user's eyesight. [0003] Aiming at the above problems, the existing solution is: add a light sensor to the mobile phone to detect ...

Problems solved by technology

Due to the mobility of the mobile phone, it is used in environments with different brightness. However, the brightness of the traditional mobile phone screen is fixed, so there is a problem: under the brightness of the indoor light, the brightness of the mobile phone screen is appropriate, but Under the outdoor sunlight, the screen of the mobile phone will be too dark to see clearly, or in a dim environment, the screen of the mobile phone will appear too bright and dazzling, causing damage to the user's vision

[0006] However, when the light sensor of the smart mobile terminal detects the ambient light, because the ambient light is in a state of instantaneous change, the light sensor has the problem of inaccurate judgment or misjudgment when detecting the ambient light.
