Abstract
The invention discloses a method for automatically regulating screen backlight duration of a mobile terminal. The method comprises the following steps: according to the computing ability of the mobile terminal, the application program running in the current foreground and the difference of tasks being fulfilled by the user, a mobile terminal records the time that the user operates the terminal within the latest period and computes the time of closing the screen backlight or reducing the backlight brightness the next time, thereby achieving the purpose of automatically regulating the screen backlight duration in different situations. Compared with the traditional method of setting only one fixed backlight timeout, the method is more power-efficient and can meet the requirements of the user under different circumstances.
Description
Technical field
The present invention relates to a kind of portable terminal and adjust the method for screen backlight duration automatically; Relate in particular to the difference of the task that a kind of portable terminal accomplishes according to the application program and the user of the computing power of self, current front stage operation; Through writing down the time of user's operating terminal in the nearest time period; And calculate the time of closing screen backlight next time or reducing backlight illumination, be adjusted at different sight sub-screens duration backlight, save power, the purpose of prolongs standby time automatically thereby reach.
Background technology
Along with the development of infotech, the function of portable terminal is more and more abundanter, and screen is increasing, accordingly also just power consumption more.Traditional portable terminal all is in system is provided with, to preset a fixing duration; Or set a fixing duration by the user; When the terminal detects that the user does not have operating terminal in this duration scope, just close the screen backlight lamp or reduce the brightness of screen backlight lamp.When this fixing duration was longer, portable terminal will compare power consumption.When this fixing duration more in short-term; When user's operation part application program is moved,, the user often occurs also not read current content displayed like reading electronic book, browsing page etc.; Just surpassed this duration, screen lamp is closed automatically or has been reduced brightness.When also having the part portable terminal to be employed in operation certain applications program, the mode that the screen backlight lamp is bright always, but this can cause the big problem of power consumption equally.
Summary of the invention
Deficiency to prior art; The objective of the invention is to address the above problem; Through portable terminal according to the application program of current front stage operation and user in the time period recently under this application program the difference of operating frequency; Thereby be adjusted at different application sub-screen duration backlight automatically, practiced thrift electric weight, satisfy user's needs preferably.
The present invention realizes through following technical scheme.
A kind of portable terminal is adjusted the method for screen backlight duration automatically, and described portable terminal begins to write down forward the time point of nearest n user's operating mobile terminal from current point in time, and calculates the time interval X of each operation.Calculate the function of time interval X then
f(x), add corrected value time a.Count from the time point of nearest operation 1, continue backward
f(x)+time period of a in if user's operating terminal not, then the terminal is closed screen backlight automatically or is lowered backlight illumination.
The time point of described user's operating mobile terminal refers to that the user normally uses the operation of portable terminal, comprises using the operation of portable terminal physical keyboard, touch screen operation and external terminal operation, does not contain the operation of lighting screen backlight.
Described nearest be meant from last operating mobile terminal for n time counted, and analogizes forward successively.The numerical value of n is changeable, can adjust according to the computing power at terminal or the application program or the current ongoing task of user of current activation.
Described time interval X refers to the time interval duration of adjacent twice operation, like X second.
The function of described time interval X
f(x) be meant n-1 time interval data handled; Processing mode can be adjusted according to the computing power at terminal or the application program or the current ongoing task of user of current activation, but like calculating horizontal mean and standard deviation, desirable maximal value, desirable mode etc.
Described correction time, a was meant the time value that the terminal is set, and this time value can be adjusted according to the application program or the current ongoing task of user of current activation.
Description of drawings
Fig. 1 adjusts the synoptic diagram of screen backlight time automatically for portable terminal of the present invention.
Embodiment
How further specify the present invention below in conjunction with accompanying drawing realizes.
Shown in Fig. 1, portable terminal begins to write down forward the time point of nearest n user's operating mobile terminal from current point in time, and the record result is respectively operation 1, operation 2, operation 3 ... Up to operation n.And calculating the time interval X of each operation, result of calculation is respectively X1, X2, X3, X4 ... Up to Xn-1.Calculate the function of time interval X then
f(x), add corrected value time a.Count from the time point of nearest operation 1, continue backward
f(x)+time period of a in if the user does not have the record of operating terminal, then the terminal is closed screen backlight automatically or is lowered backlight illumination.
The present invention more can practice thrift terminal power, prolongs standby time than traditional method that only adopts a set time section to control screen backlight or reduction backlight illumination.
