Embodiment
Primary display due to mobile terminal is all often that the middle section concentrating on screen carries out representing, and soft background light can make the sight of user ignore sharp-pointed things around, is absorbed on screen, thus reaches the effect of visually extended screen.Based on this theory, the invention provides a kind of screen visual expansion method and system of mobile terminal.Specifically, screen visual expansion method of the present invention is mainly through when the screen display of mobile terminal, obtain the current rgb value of the pixel of the current display frame of screen, and carry out except making an uproar according to current rgb value to the pixel of current display frame, obtain effective rgb value of effective pixel points and correspondence thereof, again according to the background light of effective rgb value adjustment mobile terminal, thus reach the object of the screen area visually expanding mobile terminal.
Below in conjunction with drawings and Examples, screen visual expansion method of the present invention is described in detail.
Fig. 1 is the process flow diagram of screen visual expansion method one embodiment of mobile terminal of the present invention.As shown in Figure 1, the screen visual expansion method of the present embodiment comprises:
Step S110: when the screen display of mobile terminal, obtains the current rgb value of the pixel of the current display frame of screen;
In the present embodiment, mobile terminal open and screen display time, namely start to carry out shot operation to the current display frame of screen in real time, obtain a picture.Wherein, picture form can for Bmp (bitmap), jpg or other can be suitable for the form that algorithm obtains picture rgb value.In addition, in the present invention, because picture is only for generating embodiment algorithm corresponding to different-format to obtain current rgb value, therefore it only need be temporary in Installed System Memory in acquisition process, can be removed after the current rgb value of acquisition.
Then, a selected query region in picture, use algorithm to obtain the current rgb value of pixel in query region, wherein, query region is four, the upper and lower, left and right fringe region of picture, and the width of four fringe regions is 10% of the corresponding length and width of picture.
It should be noted that, the present embodiment preferably obtains the rgb value of pixel from bitmap picture, and the algorithm adopted is bitmap.getPixel (int x, int y) algorithm, its concrete acquisition and query script can consult prior art, repeat no more herein.
Step S120: according to current rgb value, carries out except making an uproar to the pixel of current display frame, obtains effective rgb value of effective pixel points and correspondence thereof;
In the present embodiment, first time need be carried out except making an uproar to the current rgb value of the pixel of current display frame, specifically: in the query region of picture, choose one group of pixel near screen edge, statistical method is then used therefrom to choose the maximum pixel of display, and using its rgb value as reference rgb value.By the current rgb value of all pixels respectively compared with a reference rgb value, if current rgb value is positioned at a level threshold value scope pre-set (such as :-10 ~+10) with the difference with reference to rgb value, then judge that pixel is as effective pixel points, corresponding current rgb value is effective rgb value; If the current rgb value of a certain pixel and the difference with reference to rgb value beyond level threshold value scope, then judge that this pixel is as noise pixel, corresponding current rgb value is invalid rgb value, and casts out this value.Wherein, when so-called noise pixel is the display of a kind of picture compared with background color, show more sharp-pointed pixel, in order to show the white pixel point of character and to show the hair of people or the pixel of skin on such as background colour.
Step S130: according to effective rgb value, the background light of adjustment mobile terminal.
Best viewing experience is visually obtained in order to make user, the present embodiment also needs the brightness value determining the current display frame of screen, then combine with effective rgb value that step S120 obtains according to this brightness value, and then the background light of common adjustment mobile terminal, the brightness value and its Show Color intensity that make it have correspondence are corresponding with effective rgb value.In the present embodiment, the adjustment for brightness value can be realized by the size controlling the light source output voltage to background light of mobile terminal.
Above-described embodiment is by obtaining current rgb value and the brightness value of the pixel of the current display frame of screen of mobile terminal, and carry out except making an uproar to the pixel of current display frame, obtain effective rgb value of effective pixel points and correspondence thereof, then according to the background light of effective rgb value in conjunction with brightness value correspondence adjustment mobile terminal, visually can expand the area of the screen of mobile terminal, improve the display effect of screen, bring user better visual experience.
Be directed to the mobile terminal such as the mobile phone of current popular, panel computer (PAD) and generally adopt Android system (Android), and when mobile terminal adopts Android system to run, on screen, often there is Title Bar (the Title Bar of Accelerated Parallel Processing of APP, accelerate the title block of parallel processing), and it is set as black by Android system.Therefore want to obtain closest to the most effective effectively rgb value, present invention also offers another embodiment, namely in the step S120 of above-described embodiment, carry out first time after making an uproar and carry out second time except making an uproar again.Specifically:
For average R color shaping array, average B color shaping array and average G color shaping array that effective rgb value of four fringe regions is corresponding, value in each shaping array sorted according to size sequence, after carrying out sequence, each shaping array comprises corresponding minimum value, the first intermediate value, the second intermediate value and maximal value respectively.
Then for each shaping array, the mean value choosing the first intermediate value and the second intermediate value respectively as with reference to value, then by minimum value with maximal value respectively compared with reference value, one less with reference value difference in both acquisitions, and be worth as the 3rd.
Then, the mean value of the first intermediate value in each shaping array, the second intermediate value and the 3rd value is obtained, as the desired value in each shaping array.The last background light jointly adjusting mobile terminal again in conjunction with brightness value, the brightness value and its Show Color intensity that make it have correspondence are corresponding with desired value.
