Embodiment
A kind of processing method and adopt the mobile phone of this method of economizing on electricity provided by the present invention, clearer, clear and definite for making the object of the invention, technical scheme and advantage, below develop simultaneously embodiment to further explain of the present invention with reference to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
A kind of economize on electricity processing method based on mobile phone that the embodiment of the invention provided like Fig. 1, comprises step:
Step S110, detect and read the battery electric quantity information of mobile phone automatically;
Step S120, when the battery electric quantity information that is read during less than first predetermined value, the colored rgb signal that control will be input to mobile phone display screen converts black-and-white signal to, and the black-and-white signal after will changing shows on mobile phone display screen.Wherein, this first predetermined value is defined as the lower value of a battery electric quantity, as is 10% of battery electric quantity.
Below through concrete application implementation example the inventive method is done further explain:
In S1, this concrete application implementation example, a color switching software algoritic module (API) is set in advance, the colored rgb signal that the algorithm that is used to adopt color conversion to become GTG will be input to mobile phone display screen converts black-and-white signal to.
S2, when mobile phone is opened, as shown in Figure 2, the colored rgb signal that will handle well through mobile phone base band chip 10 is transferred to mobile phone display screen 11 through MIPI interface or MDDI interface; Mobile phone display screen 11 obtains the colored rgb signal of each pixel, and is presented on the screen.Get into step S3 then.
S3, every battery electric quantity information that reads mobile phone at a distance from a scheduled time automatically.For example can read battery electric quantity information automatically at set intervals through in color conversion software algorithm module (API), a timer being set.
S4, when the battery electric quantity information that is read less than the battery of mobile phone total amount 10% the time; Trigger and start said color conversion software algorithm module; And through this color conversion software algorithm module; The colored rgb signal that adopts color conversion to become the algorithm of GTG will be input to mobile phone display screen converts black-and-white signal to, and gets into step S5.
And work as the battery electric quantity information that is read be not less than the battery of mobile phone total amount 10% the time, mobile phone does not process.
In the present embodiment; Obtaining of battery electric quantity information; Can be through following method, because in the android operating system that mobile phone uses, all relevant for the information of the last electric weight of mobile phone; Can obtain in the system information in the present embodiment and just can judge, such as also surplus 30% and so on information of battery electric quantity is all arranged in cell phone system about electric weight.
Further, the color conversion of present embodiment becomes the algorithm of GTG to specifically describe as follows:
Each pixel of mobile phone liquid crystal display all has a rgb value correspondence; Different rgb values demonstrates different colors.Simultaneously, the colour display screen of checking colors shows that also having another set of expression mode is exactly YUV.Wherein Y is lightness, and U and V are colourity.And if have only Y-signal among the YUV, what show is exactly the black-and-white signal of having only 256 kinds of GTGs.
RGB is corresponding with YUV signal as follows:
yuv<-->rgb
Y''=?0.299*R''?+?0.587*G''?+?0.114*B''
U''=?-0.147*R''?-?0.289*G''?+?0.436*B''?=?0.492*(B''-?Y'')
V''=?0.615*R''?-?0.515*G''?-?0.100*B''?=?0.877*(R''-?Y'')
R''?=?Y''?+?1.140*V''
G''?=?Y''?-?0.394*U''?-?0.581*V''
B''?=?Y''?+?2.032*U''
Above-mentioned each symbol R, G, B and Y, U, V have been with two left-falling strokes, represent that this symbol has carried out gamma correction (Gamma correction) on the initial value basis.Colored rgb signal with each pixel all converts Y to then.And with U, V establish 0 just obtained having only GTG signal.According to having only the black-and-white signal of Y, inverse becomes RGB, just converts the colored rgb signal of colour to black and white colored rgb signal, and gets into step S5.
Black-and-white signal after S5, this conversion shows on mobile phone display screen.
Embodiment further, said economize on electricity processing method based on mobile phone, said method also comprises step:
S6, when mobile phone display screen becomes white and black displays; The battery electric quantity information that detects current phone is again returned when surpassing second predetermined value (for example for battery of mobile phone total amount 15%); Then automatically said color conversion software algorithm module is closed in control, and the white and black displays of mobile phone display screen is reverted to colored the demonstration.
Therefore the method for the embodiment of the invention has realized under the very low situation of cell-phone battery electric-charge quantity, and the display color of mobile phone display screen is become black and white from colour.Thereby the minimizing power consumption increases standby and service time, provides users with the convenient.
Based on the foregoing description, the embodiment of the invention also provides a kind of mobile phone, and is as shown in Figure 3, comprising:
Battery electric quantity information reading module 210 is used for every battery electric quantity information that reads mobile phone at a distance from a scheduled time automatically; Specifically as above step S3 is said.
The first color conversion software algorithm module 220, when being used to work as the battery electric quantity information that read less than first predetermined value, the colored rgb signal that adopts color conversion to become the algorithm of GTG will be input to mobile phone display screen converts black-and-white signal to; Specifically of above-mentioned step S4.
First display control module 230, the black-and-white signal that is used to control after will changing shows on mobile phone display screen; Specifically of above-mentioned step S5.
Second display control module 240, when mobile phone display screen became white and black displays, the battery electric quantity information that detects current phone was again returned when surpassing second predetermined value, and the white and black displays of then controlling automatically mobile phone display screen reverts to colored the demonstration; Specifically of above-mentioned step S6.
Wherein, said first predetermined value is 10% of a battery of mobile phone total amount; Said second predetermined value is 15% of a battery of mobile phone total amount.
In sum, economize on electricity processing method provided by the present invention and adopt the mobile phone of this method is owing to adopted automatic detection and read the battery electric quantity information of mobile phone; When the battery electric quantity information that is read during less than first predetermined value, the colored rgb signal that control will be input to mobile phone display screen converts black-and-white signal to, and the black-and-white signal after will changing shows on mobile phone display screen; It makes mobile phone increase the new function that economize on electricity is handled, and under the very low situation of cell-phone battery electric-charge quantity, the display color of mobile phone display screen is become black and white from colour.Thereby the minimizing power consumption increases standby and service time, provides users with the convenient.
