Fig. 2 is a kind of flow chart of screen display method according to an exemplary embodiment, as shown in Fig. 2 screenDisplay methods is used in terminal, comprises the following steps.
In step 201, whether the luminance difference between terminal monitoring display screen and current environment is more than the second present countValue, if it is, step 202 is performed, if not, continuing to monitor.
Wherein, terminal is the equipment with display screen, e.g., smart mobile phone, tablet personal computer, TV, game machine etc., this realityApply example and specific limit is not made to the type of terminal.Current environment refers generally to the environment residing for terminal, if user is closed in lightThe indoor using terminal closed, then current environment is indoor environment；If user's night is in outdoor application mobile phone, current environmentOutdoor environment.Current environment can be the dark environment of brightness or the dark environment of brightness, and the present embodiment is to work as front ringBorder is to illustrate exemplified by the dark environment of brightness.
When whether luminance difference of the terminal between monitoring display screen and current environment is more than the second default value, can first it obtainTake the brightness value that display screen is current, and obtain the brightness value of current environment, and by the brightness value of the display screen got withThe brightness value of current environment is compared, and according to comparative result, determines whether is luminance difference between display screen and current environmentMore than the second default value.Wherein, the second default value can be 3cd/m2(candela/square metre), 5cd/m2、8cd/m2Deng,The present embodiment does not make specific limit to the size of the second default value.
In step 202, terminal generation brightness regulation instruction.
When monitoring that the luminance difference between the brightness of display screen and current environment is more than the second default value, illustrate nowThe display screen of terminal is excessively bright, it is necessary to the brightness of screen is dimmed, and to mitigate the regulation burden of eyes, avoids the eyes to userDamage.Therefore, terminal will generate a brightness regulation instruction, brightness regulation instruction can be used for terminal displayBrightness dims.
In step 203, instructed based on brightness regulation, three colors that terminal obtains each pixel on display screen are led toThe brightness value in road.
Based on brightness regulation instruction is got, under the triggering of brightness regulation instruction, terminal will be obtained on display screenThe brightness value of three Color Channels of each pixel.Wherein, three Color Channels are that red (R) Color Channel, green (G) color are led toRoad, indigo plant (B) Color Channel.R, each Color Channel of G, B is divided into 255 rank brightness values, and 0 rank brightness is most dark, and 255 rank brightness are mostIt is bright.When the brightness value of tri- Color Channels of R, G, B is identical, gray color is shown as, the gray color can be white, black or ashColor, specifically, if the brightness value of tri- Color Channels of R, G, B is 0 rank, black is shown as, if tri- colors of R, G, BWhen the brightness value of passage is 255 rank, white is shown as；When the brightness value difference of tri- Color Channels of R, G, B, coloured silk is shown asColor.
In step 204, for any pixel point, terminal judges any two face in three Color Channels of the pixelWhether the luminance difference between chrominance channel is more than the first default value, if it is, step 205 is performed, if it is not, then performing step206。
In practical application, contrast of the contrast of white background, black background and gray background with respect to color backgroundDegree is big, when indoor using terminal of the user in dark, white background, black background and gray background be more easy toThe eyesight at family damages, and adopts and the pixel on display screen is handled in a like fashion, corresponding to color backgroundThe color that pixel is showed is more easy to distortion.Suffered damage in order to avoid the eyesight of user, while keep webpage, video, electronicsThe color effect of the background colours such as book, the present embodiment, which provides method, can be directed to each pixel, using different brightness adjustment approachBrightness to each pixel is adjusted.
Before being adjusted using brightness of the different brightness adjustment approach to each pixel, terminal is needed according to eachThe brightness value of three Color Channels of pixel carries out brightness judgement to each pixel, so as to according to judging that brightness results areEach pixel chooses corresponding regulative mode.Any pixel point being directed on display screen, when specifically judging, terminal needsFirst obtain the luminance difference between any two Color Channel in three Color Channels of the pixel, and then the luminance difference that will be obtainedCompared with the first default value, according to comparative result, any two color in three Color Channels of the pixel is judgedWhether the luminance difference between passage is more than the first default value.Wherein, when the first default value is that pixel shows as colour, threeThe minimum value of luminance difference in individual Color Channel between any two Color Channel, first default value can be 8cd/m2、10cd/m2、16cd/m2Deng the present embodiment not specific restriction of size work to the first default value.
It should be noted that for any pixel point, any two in three Color Channels for calculating the pixelDuring brightness value between individual Color Channel, three luminance differences are can obtain, in three Color Channels for judge the pixel arbitrarilyWhen whether the luminance difference between two Color Channels is more than the first default value, and if only if, and three luminance differences are simultaneously greater than firstDuring default value, step 205 is performed；When any one in three luminance differences is less than the first default value, step 206 is performed.
In step 205, terminal is adjusted using the first preset algorithm to the brightness value of each Color Channel of pixelSection, obtain the brightness value after pixel regulation.
When the luminance difference between any two Color Channel in three Color Channels for judge the pixel is more than firstDuring default value, illustrate that the color that the pixel is showed is colored and three Color Channels of the pixel brightness value differenceIt is larger, the brightness value of each Color Channel of the pixel can be now adjusted using the first preset algorithm.
When it is implemented, terminal can use the first preset algorithm, the brightness value of each Color Channel of pixel is reducedIdentical multiple, obtain the brightness regulation value of each Color Channel, and then the brightness regulation value based on each Color Channel, pass through byThe brightness regulation value of three Color Channels is overlapped, and obtains the brightness value after pixel regulation.Wherein, the first preset algorithm is such asShown in following formula (1)：
Yi=Xi/n (1)；
Wherein, YiFor the brightness regulation value of each Color Channel, XiFor the brightness value of each Color Channel, i=1,2,3, Y1For the brightness regulation value of beauty chrominance channel, X1For the brightness value of beauty chrominance channel, Y2For the brightness regulation value of green color passage, X2For the brightness value of green color passage, Y3For the brightness regulation value of blue Color Channel, X3For the brightness value of blue Color Channel, n is diminutionMultiple.Certainly, the first preset algorithm can also have other forms, and the present embodiment no longer illustrates one by one.
It is adjusted by using the first preset algorithm, the brightness value after pixel regulation can be obtained.If for example, pictureThe brightness value X of the beauty chrominance channel of vegetarian refreshments1For 160cd/m2, green color passage brightness value X2For 240cd/m2, blue Color ChannelBrightness value X3For 120cd/m2, the multiple of diminution is 4 times, then using the formula in above-mentioned (1), can obtain：
Y1=X1/ n=160/4=40cd/m2；
Y2=X2/ n=240/4=60cd/m2；
Y3=X3/ n=120/4=30cd/m2；
By by the brightness regulation value of beauty chrominance channel obtained above, the brightness regulation value of green color passage and blue faceThe brightness regulation value of chrominance channel is overlapped, and can obtain the brightness value after pixel regulation.
In step 206, terminal is adjusted using the second preset algorithm to the brightness value of each Color Channel of pixelSection, obtain the brightness value after pixel regulation.
When the luminance difference between any two Color Channel in three Color Channels for judge the pixel is less than firstDuring default value, illustrate that the brightness value difference of three Color Channels of the pixel is smaller, can now use the second preset algorithmThe brightness value of each Color Channel of the pixel is adjusted.
When it is implemented, terminal can use the second preset algorithm, by the brightness regulation value of each Color Channel of pixelGiven luminance scope is adjusted, obtains the brightness regulation value of each Color Channel, and then the brightness based on each Color Channel is adjustedSection value, by the way that the brightness regulation value of three Color Channels is overlapped, obtain the brightness value after pixel regulation.Wherein, refer toIt is terminal brightness range according to determined by the brightness value of current environment to determine brightness range, and the given luminance may range from 0cd/m2~32cd/m2、40cd/m2~60cd/m2Deng.Shown in for example following formula (2) of second preset algorithm：
Yi=a+Xi/255*(b-a) (2)；
Wherein, YiFor the brightness regulation value of each Color Channel, XiFor the brightness value of each Color Channel, i=1,2,3, Y1For the brightness regulation value of beauty chrominance channel, X1For the brightness value of beauty chrominance channel, Y2For the brightness regulation value of green color passage, X2For the brightness value of green color passage, Y3For the brightness regulation value of blue Color Channel, X3For the brightness value of blue Color Channel, a is specifiedThe minimum value of brightness range, b are the maximum of given luminance scope.Certainly, the second preset algorithm can also have other forms, thisEmbodiment no longer illustrates one by one.
It is adjusted by using the first preset algorithm, the brightness value after pixel regulation can be obtained.If for example, pictureThe brightness value X of the beauty chrominance channel of vegetarian refreshments1For 233cd/m2, green color passage brightness value X2For 235cd/m2, blue Color ChannelBrightness value X3For 230cd/m2, given luminance may range from 0cd/m2~32cd/m2, i.e. a=0cd/m2, b=32cd/m2,The formula in above-mentioned (2) is then used, can obtain：
Y1=a+Xi/ 255* (b-a)=0+233* (32-0)/255=29.2；
Y2=a+X2/ 255* (b-a)=0+235* (32-0)/255=29.5；
Y3=a+X3/ 255* (b-a)=0+230* (32-0)/255=28.9；
By by the brightness regulation value of beauty chrominance channel obtained above, the brightness regulation value of green color passage and blue faceThe brightness regulation value of chrominance channel is overlapped, and can obtain the brightness value after pixel regulation.
In step 207, when all pixels point is through overregulating, terminal carries out screen based on the brightness value after regulation and shownShow.
After all pixels on display screen are adjusted using above-mentioned brightness method for turning down sound, terminal rootBrightness value after being adjusted according to each pixel, you can carry out screen display.Now the background colour on screen not only will not distortion, andAnd screen intensity will not also damage to the eyes of user.
So far, realized by above-mentioned steps 201 to 207 under the dark environment of brightness, to the tune of terminal displayDark operation.On this basis, if the brightness of the environment residing for terminal becomes strong suddenly, e.g., user opens the light of interior, thisWhen excessively dark display screen the eyesight of user can also be damaged, therefore, the method that the present embodiment provides is detecting displayWhen luminance difference between screen and current environment is more than the second default value, execution is lightened to the operation of display screen.
During specific execution, terminal will generate a brightness regulation instruction, and brightness regulation instruction can be used for showing terminalDisplay screen curtain lightens, and afterwards, under the triggering of brightness regulation instruction, terminal can obtain three of each pixel on display screenThe brightness value of Color Channel.Any pixel point being directed on display screen, if it is determined that in three Color Channels of pixelLuminance difference between any two Color Channel is more than the first default value, and terminal can use the 3rd preset algorithm to the pixelIn the brightness value of each Color Channel be adjusted.3rd preset algorithm can be Zi=Xi/ n, wherein, ZiFor each faceThe brightness regulation value of chrominance channel, XiFor the brightness value of each Color Channel, i=1,2,3, Z1For the brightness regulation of beauty chrominance channelValue, X1For the brightness value of beauty chrominance channel, Z2For the brightness regulation value of green color passage, X2For the brightness value of green color passage, Z3For the brightness regulation value of blue Color Channel, X3For the brightness value of blue Color Channel, n is the multiple of amplification.If it is determined that pixelThree Color Channels in luminance difference between any two Color Channel be less than the first default value, terminal can be according to working as front ringThe brightness value in border, a brightness range is determined, and then the brightness is arrived into the brightness value regulation of each Color Channel of the pixelScope.When using above-mentioned brightness heighten method to each pixel is adjusted on display screen after, terminal can be carried outScreen display.
