Specific embodiment
In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention also may be implemented in the other embodiments of details.In other situations, it omits to well-known system, system, electricity
The detailed description of road and method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.Referring to FIG. 1,
Fig. 1 shows a kind of implementation process of the screen luminance adjustment method of terminal device provided in an embodiment of the present invention, and details are as follows:
In step s101, it when needing that the screen intensity of the terminal device is adjusted, obtains the terminal and sets
Standby image Buffer.
In embodiments of the present invention, when needing the screen intensity to terminal device to be adjusted, for example ambient light intensity is big
When default light intensity value or user manually adjust the screen intensity of terminal device, the image Buffer of terminal device is obtained,
Image Buffer includes the image Buffer of the current display interface of terminal device.
Optionally, above-mentioned image Buffer includes at least two image Buffer, which is adjacent
Two field pictures Buffer.
Optionally, referring to FIG. 2, Fig. 2 shows one kind provided in an embodiment of the present invention determine the need for it is bright to screen
The specific implementation flow for the method being adjusted is spent, details are as follows:
In step s 201, by light sensor, the ambient light intensity of the terminal device is obtained.
In embodiments of the present invention, light sensor is equipped in terminal device, it is referred herein for obtaining ambient light intensity
Ambient light intensity be terminal device ambient enviroment luminous intensity, for example ambient light intensity acquired in daytime is greater than evening institute
The ambient light intensity of acquisition.
As an embodiment of the present invention, since ambient light intensity changes less within a certain period of time, step
S201 specifically:
By light sensor, it is spaced the ambient light intensity that preset time obtains the terminal device.
In step S202, by the absolute value of the difference of the ambient light intensity and the last ambient light intensity obtained with
Preset threshold is compared.
In embodiments of the present invention, it by calculating the difference of the ambient light intensity obtained twice recently, and will be calculated
The absolute value of difference be compared with preset threshold with whether the ambient light intensity for judging terminal device is changed.
In step S203, determine whether the ambient light intensity of the terminal device is changed according to comparison result.
In embodiments of the present invention, comparison result includes the first comparison result and the second comparison result, wherein first compares
As a result are as follows: the absolute value of the difference of ambient light intensity and the last ambient light intensity obtained is greater than preset threshold；Second compares
As a result the absolute value for the difference of ambient light intensity and the last ambient light intensity obtained is less than or equal to preset threshold, this
When, step S203 specifically:
If the absolute value of the difference of the ambient light intensity and the last ambient light intensity obtained is greater than preset threshold,
Determine that the ambient light intensity of the terminal device is changed；

Luminance bar with length corresponds to different screen intensity adjustment factors, and gradually increases from left to right from screen intensity adjustment factor
Greatly, i.e., luminance bar more leans on the right, and screen intensity adjustment factor is bigger, and screen is brighter.
In step s 102, according to default adjusting ratio, to the RGB channel value of each pixel of described image Buffer
It is adjusted.
In embodiments of the present invention, it when determination needs that the screen intensity of terminal device is adjusted, does not adjust directly
The screen back light value of terminal device is saved, i.e. the screen back light value of holding terminal device is constant, adjusts according to preset ratio
The RGB channel value of each pixel in image Buffer is saved, so that the brightness of each pixel enhances, to reach adjusting eventually
The purpose of the screen intensity of end equipment.
Herein, presetting adjusting ratio is one or more ratio values by repeatedly testing, different channel values
Corresponding identical ratio value or different channel values correspond to different ratio values.
Optionally, step S102 specifically:
According to corresponding default adjusting ratio, respectively to the RGB channel value of each pixel of described image Buffer into
Row is adjusted.
In embodiments of the present invention, in the image processing arts, each pixel is by tri- Color Channel tables of RGB
Show, range 0-255, respectively represent red, green, blue, the corresponding value of tri- Color Channels of RGB is known as RGB by the embodiment of the present invention
Channel value comprising the channel value of the channel value in the channel R, the channel value of channel B and the channel G, the range of the channel value be [0,
255]。
Herein, the brightness of pixel is adjusted by three channel values that adjustable range is [0,255], to reach increasing
The purpose of the brightness of strong image Buffer.

Buffer realizes that the screen intensity to terminal device automatically adjusts.
Herein, the switch button that screen intensity is adjusted is provided on the screen of terminal device, so that user can pass through
Button selection is turned on or off screen intensity regulatory function.After opening screen intensity regulatory function, can in real time according to
Default adjusting ratio, is adjusted the RGB channel parameter of each pixel of acquired image Buffer, realizes to described
The adjusting of the screen intensity of terminal device can also be spaced some cycles according to default adjusting ratio, to acquired multiple figures
As the RGB channel parameter of each pixel of Buffer is adjusted, the adjusting to the screen intensity of the terminal device is realized.
It is understood that the unlatching of screen intensity regulatory function, which has no effect on user, manually adjusts screen intensity.Work as pass
After closing screen intensity regulatory function, terminal device is not to determine further according to ambient light intensity and the comparison result of default luminous intensity
The screen intensity of the terminal device is adjusted in no needs.
In embodiments of the present invention, it is set by when needing the screen intensity to terminal device to be adjusted, obtaining terminal
Standby image buffer storage Buffer adjusts the RGB channel value of each pixel of image Buffer according to default adjusting ratio
Section, the image Buffer after the rgb value of each pixel is adjusted are exported to the screen end of terminal device, are realized to terminal device
Screen intensity adjusting；Each pixel of the logical image Buffer for adjusting acquired terminal device of the embodiment of the present invention
Rgb value realizes the adjusting to screen intensity, to no longer need to control size of the screen backlight to adjust screen intensity, also
It not will increase the power consumption of screen, to realize the power consumption for reducing terminal device, guarantee the cruising ability of terminal device and mention
The high service life of battery, so that user experience is more preferable.
