Embodiment
For problems of the prior art, a kind of scheme that automatically can adjust screen display brightness according to the light situation of change of external environment condition is proposed in the present invention, namely when after the arbitrary application program on user opens a terminal, terminal obtains the brightness value of external environment condition in real time, and adjusts screen display brightness according to the brightness value of the external environment condition got; Wherein, the brightness value of external environment condition is larger, and screen display brightness is higher, and the brightness value of external environment condition is less, and screen display brightness is lower.
Specifically, can be terminal and be pre-created a shade (Mask View), when after the arbitrary application program on user opens a terminal, start this Mask View, cover the user interface (UI of this application program, User Interface) layer, follow-up, when after the brightness value getting external environment condition at every turn, according to the mapping relations between the brightness value of the external environment condition of preserving in advance and alpha value, determine the alpha value that the brightness value of the external environment condition got is corresponding, and determine that whether the alpha value of this correspondence is consistent with the alpha value of the background color of Mask View, if inconsistent, then the alpha value of the background color of Mask View is adjusted to the alpha value of this correspondence.
For make technical scheme of the present invention clearly, understand, to develop simultaneously embodiment referring to accompanying drawing, scheme of the present invention be described in further detail.
Fig. 1 is the process flow diagram of screen display luminance regulating method embodiment of the present invention.
Step 11: for terminal creates a Mask View.
How creating Mask View is prior art.
In simple terms, Mask View itself is the picture of a portable network graphics format (PNG, Portable Network Graphic Format), is drawn out by a translucent PNG picture, namely define Mask View on UI layer.
Step 12: when after the arbitrary application program on user opens a terminal, terminal starts the Mask View created, and the brightness value of Real-time Obtaining external environment condition.
Mask View can cover the UI layer of the application program that user opens, and make screen display effect out more soft, convenient user browses.
For example, suppose that user is browsing a webpage, so namely Mask View is equivalent on this webpage, add the soft cover of one deck.
For terminals such as existing comparatively high-end mobile phones, wherein can be provided with a light intensity sensor (Light Intensity Sensor), this Light Intensity Sensor can be utilized to carry out the brightness value of real-time detection external environment condition; If do not arrange Light Intensity Sensor in terminal, then need to carry out certain transformation to it, namely add Light Intensity Sensor.Here mentioned real-time detection is a relative concept, does not refer to and detects incessantly always, and refer at regular intervals, within such as 1 minute, once detect.
Step 13: terminal is after the brightness value at every turn getting external environment condition, according to the mapping relations between the brightness value of the external environment condition of preserving in advance and alpha value, determine the alpha value that the brightness value of the external environment condition got is corresponding, and determine that whether the alpha value of this correspondence is consistent with the alpha value of the background color of Mask View, if inconsistent, then the alpha value of the background color of Mask View is adjusted to the alpha value of this correspondence.
Each PNG picture has the parameter of a characterizing transparent degree, be called alpha value, how adjusting alpha value is prior art, in simple terms, application programming interfaces (API, Application Programming Interface) by picture adjust alpha value.
The adjustment of alpha value will directly affect the transparency of Mask View, and then affects the screen display brightness of terminal.Specifically, alpha value is larger, and transparency is larger, and screen display brightness is higher; Otherwise alpha value is less, and transparency is less, screen display brightness is lower.Relation below demand fulfillment between the brightness value of external environment condition and alpha value: the brightness value of external environment condition is larger, and alpha value is larger; Otherwise the brightness value of external environment condition is less, alpha value is less.Like this, if in the strong outdoor of light, so then need screen display brightness to heighten, if in the indoor of relative darkness, then need screen display brightness to turn down.
Usually, the span of brightness value is the span of 0 ~ 100, alpha value is 0 ~ 1.
In actual applications, different range of luminance values alpha value corresponding different respectively can be set; Or, the alpha value that different brightness values is corresponding different respectively.Which kind of mode of concrete employing can be decided according to the actual requirements, for avoiding adjusting continually, and a kind of mode before many employings.
In addition, how which range of luminance values which alpha value corresponding is set, which brightness value which alpha value corresponding all can be determined according to practical experience, be not construed as limiting in the present invention.Such as: can arrange when range of luminance values is 0 ~ 10, corresponding alpha value is 0.1, and when range of luminance values is 11 ~ 20, corresponding alpha value is 0.2, and when range of luminance values is 21 ~ 30, corresponding brightness value is 0.3, the like; Or, the corresponding alpha value 0 of brightness value 0 is set, the corresponding alpha value 0.01 of brightness value 1, the corresponding alpha value 0.02 of brightness value 2, the like.
Have again, if arrange the alpha value that different range of luminance values is corresponding different respectively, so will likely there is following situation, namely double even more times brightness value got of terminal is all positioned at same range of luminance values, such as: the brightness value got for the N time is 24, after the alpha value of the background color of Mask View is adjusted to 0.3 by the brightness value got according to this time, the brightness value got for the N+1 time is 25, because the alpha value of brightness value 24 and 25 correspondence is 0.3, therefore, by without the need to adjusting the alpha value of the background color of Mask View again, obviously, if the brightness value got for the N+1 time is 35, then need the alpha value of the background color of Mask View to be adjusted to 0.4.
So far, the introduction about the inventive method embodiment is namely completed.
Based on above-mentioned introduction, Fig. 2 is the composition structural representation of terminal embodiment of the present invention.As shown in Figure 2, comprising:
