Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] Since the light sensor reduces the sensing ability to high-brightness ambient light, the accuracy of the light sensor to detect the ambient light decreases with the increase of the ambient light brightness, and the light sensor tends to be unstable when detecting the ambient light. In order to solve the above-mentioned stability of the light sensor under high brightness, the present invention provides the following solutions and a system thereof.

[0040] The invention provides a method for improving the detection stability of the light sensor, such as figure 1 shown, including t...

Abstract

The invention provides a method and a system for enhancing light sensor detection stability and an intelligent terminal. Ambient light intensity signals and backlight brightness signals of the display screen of the intelligent terminal before and after a period of time are acquired through the light sensor of the intelligent terminal. If the ambient light intensity signal values detected before and after the period of time are greater than the backlight brightness signal values, a central processor is triggered to control voltage signals outputted by the light sensor to perform voltage stabilization processing and then light intensity detection values detected by the light sensor are outputted so that outputting of the stable light intensity detection values can be realized, and acquisition of the accurate light intensity detection values is facilitated for users.

Description

technical field [0001] The invention relates to the technical field of brightness detection, in particular to a method, system and intelligent terminal for improving the detection stability of a light sensor. Background technique [0002] When the light sensor of the smart smart terminal detects ambient light, the ambient light detection may be unstable. Since the ambient light includes sunlight, the brightest state of the light cannot be predicted, and the light sensor of the smart smart terminal cannot detect the brightest state of the ambient light, so the light sensor will detect the brightness of the ambient light for a long time. Guaranteed to improve the accuracy of detecting ambient light as much as possible. As the brightness of the ambient light increases, the accuracy of the light sensor to detect the ambient light becomes lower and lower, and the light sensor becomes less sensitive to high-brightness ambient light, so the light sensor tends to be unstable when d...
