Problems solved by technology

[0007] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a method and system for automatic brightness adjustment, which is used to solve the problem that the brightness adjustment technology in the prior art cannot meet the requirements of rapid changes in the external environment. The display screen brightness is set so that the mobile terminal always maintains a darker or brighter fixed brightness when the external environment is quickly switched from bright to dark.

Embodiment 1

[0044] This embodiment provides a method for automatically adjusting brightness, which is applied to mobile terminals equipped with display screens, for example, intelligent mobile terminals such as smart phones and tablet computers. In this embodiment, the automatic brightness adjustment method can be applied to a bus to solve the application scenario of driving on a road with tree shade on both sides when taking a bus, so as to solve the brightness of the external environment and quickly switch from bright to dark. Then quickly switch from dark to bright.

[0045] The brightness automatic adjustment scheme adopted by mobile terminals on the market is generally: firstly, the brightness value is normalized, assuming that the brightness value is divided into 10 levels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Assume that the luminance values ​​are all 1, 1, 1, 1 in the predetermined sampling time Δt for 4 fixed times, and the luminance values ​​are 9, 9, 9, 9 in the next predetermined s...

Embodiment 2

[0067] This embodiment provides an automatic brightness adjustment system 1, which is applied to a mobile terminal equipped with a display screen, such as a smart phone, a tablet computer and other smart mobile terminals. see image 3 , shown as a schematic diagram of the principle structure of the automatic brightness adjustment system, such as image 3 As shown, the automatic brightness adjustment system 1 includes: an instruction output module 11, a first brightness setting module 12, several brightness acquisition modules, that is, a first brightness acquisition module 13, a second brightness acquisition module 14, ... the (2+N ) brightness acquisition module 15, (3+N) brightness acquisition module 16, front brightness automatic adjustment module 17, second brightness setting module 18, rear brightness automatic adjustment module 19, third brightness setting module 10, and cycle operation module 20 .

[0068] The instruction output module 11 is configured to output an in...

Abstract

The invention provides a method for adjusting brightness automatically. The method comprises the following steps of: entering a first brightness sampling period, and acquiring a first average brightness value of a display screen during the first brightness sampling period; entering a second brightness sampling period, and acquiring a second average brightness value of the display screen during the second brightness sampling period; performing pre-brightness automatic adjustment operation; entering (2+N)th brightness sampling period, and acquiring the (2+N)th average brightness value of the display screen during the (2+N)th brightness sampling period; entering (3+N)th brightness sampling period, and acquiring the (3+N)th average brightness value of the display screen during the (3+N)th brightness sampling period, wherein N refers to the cycle index from 1; and performing post-brightness automatic adjustment operation, returning back to the step 5, and performing cyclic operation. By utilizing the method and the system, the set of brightness of the display screen can be held accurately under the condition that the external environment changes fast, and the splash screen phenomenon of a mobile terminal during the fast bright-dark switching of the external environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a method and system for automatically adjusting brightness, in particular to a method and system for automatically adjusting brightness when the brightness of the external environment changes rapidly. Background technique [0002] Contemporary communication technology is becoming more and more developed, and electronic equipment is becoming more and more advanced, especially with the development of communication technology, mobile terminals in electronic equipment, especially based on the fourth mobile communication technology (4G) and the long-term evolution system (LTE) The hardware configuration in the smart terminal of ) is becoming more and more powerful, and the function application is more and more diverse, making it a necessity for people's life and work today. [0003] Moreover, with the popularization of smart terminal devices, seeking a more natural and simp...
