In the present embodiment, screen currently shows that picture includes any one list in currently playing any image content
Frame image, it includes each pixel that this, which currently shows in picture, and each pixel respectively corresponds a brightness value.It is understood that
That each pixel has corresponding brightness, this brightness and form and aspect be it is not related, and the brightness value of pixel 0 to 255 it
Between, the pixel intensity close to 255 is higher, and the brightness close to 0 is lower, and rest part just belongs to middle tone.The differentiation of this brightness
It is a kind of absolutely differentiation, i.e., the pixel near brightness value 255 is bloom, and the pixel near brightness value 0 is shadow, and middle tone is bright
Angle value 128 or so.As shown in figure 4, Fig. 4 is each pixel schematic diagram of current picture.
S302, the ratio that the corresponding pixel of each brightness value accounts for total pixel quantity is calculated.
It should be understood that different according to the display content of current display picture, each pixel is located at the position on screen
It is also different with number；In order to count whether current display picture is light tone tone or dark-coloured tone, it is corresponding to count each brightness value
Pixel quantity, and then calculate the ratio that the corresponding pixel of each brightness value accounts for total pixel quantity.Certain current screen is shown
The timing of region one, and the resolution ratio of screen is also a timing, screen currently show total pixel quantity of picture be also it is certain,
Such as resolution ratio just refers to and has divided 1366 pixels in the transverse direction of plasma screen when being 1366 × 768, it is vertical upper to draw
768 pixels are divided, then screen currently shows that total pixel quantity of picture is 1366 × 768.In order to make it easy to understand,
This is illustrated to the ratio that the corresponding pixel of each brightness value accounts for total pixel quantity is calculated.Assuming that currently showing picture
Total pixel be 2000, the pixel that brightness value is 200 is 1400, then brightness value be 200 pixel account for total pixel
The ratio of quantity is 1400/2000=70%, and the pixel for then calculating each brightness value extremely according to the example above method accounts for always
The ratio of pixel quantity.
S303, judge whether ratio is more than or equal to presetted pixel proportion threshold value, if so, turning S304, if not, terminating.
In the present embodiment, judge whether ratio is more than or equal to presetted pixel proportion threshold value, can be judgement be greater than etc.
Whether the ratio that the pixel corresponding to the brightness value of the first predetermined luminance threshold value accounts for total pixel quantity is more than or equal to first
Presetted pixel proportion threshold value；Wherein the first predetermined luminance threshold value, the first presetted pixel proportion threshold value can be customized by the user and set
It sets, is also possible to be arranged by terminal, certain first predetermined luminance threshold value, the specific value of the first presetted pixel proportion threshold value can be with
It is adjusted flexibly according to the actual situation.Such as pixel corresponding to brightness value of the judgement more than or equal to 200 accounts for total pixel quantity
Ratio whether be more than or equal to 60%, that is, judge brightness value be more than 200 pixel ratio whether more than 60%；Certainly judge ratio
Whether being more than or equal to presetted pixel proportion threshold value can also be that judgement is right less than or equal to the brightness value of the second predetermined luminance threshold value institute
Whether the ratio that the pixel answered accounts for total pixel quantity is more than or equal to the second presetted pixel proportion threshold value；Similarly first preset it is bright
Degree threshold value, the first presetted pixel proportion threshold value can be customized by the user setting, be also possible to be arranged by terminal, can also basis
Actual conditions are adjusted flexibly.Such as pixel corresponding to brightness value of the judgement less than or equal to 30 accounts for the ratio of total pixel quantity
Whether it is more than or equal to 65%, that is, judges pixel ratio of the brightness value lower than 30 whether more than 65%.
It should be understood that in the present embodiment, judging whether ratio is more than or equal to presetted pixel proportion threshold value and can be
Only judgement be more than or equal to the first predetermined luminance threshold value brightness value corresponding to pixel account for total pixel quantity ratio whether
More than or equal to the first presetted pixel proportion threshold value, it is also possible to only judge to be less than or equal to the brightness value institute of the second predetermined luminance threshold value
Whether the ratio that corresponding pixel accounts for total pixel quantity is more than or equal to the second presetted pixel proportion threshold value, and first is default at this time
Pixel ratio threshold value and the second presetted pixel proportion threshold value may be the same or different；Can also be at the same judge be greater than etc.
The pixel corresponding to the brightness value of the first predetermined luminance threshold value accounts for the ratio of total pixel quantity and is less than or equal to second in advance
If whether the ratio that pixel corresponding to the brightness value of luminance threshold accounts for total pixel quantity is greater than equal presetted pixels ratio threshold
Value, at this point, the first predetermined luminance proportion threshold value and the second predetermined luminance proportion threshold value should be different.
S304, the brightness value that screen currently shows picture is adjusted.
It should be understood that adjusting screen currently shows that the brightness value regulative mode of picture can be according to current display picture
The pixel intensity in face carries out Automatic Optimal.Specifically, working as picture corresponding to the brightness value more than or equal to the first predetermined luminance threshold value
When the ratio that vegetarian refreshments accounts for total pixel quantity is more than or equal to the first presetted pixel proportion threshold value, if brightness value is more than 200 pixel
Whether ratio then shows currently to show that picture belongs to light tone tone, user can think that picture is dazzling more than 60%；When being less than or equal to
The ratio that pixel corresponding to the brightness value of second predetermined luminance threshold value accounts for total pixel quantity is more than or equal to the second default picture
When plain proportion threshold value, whether the pixel ratio such as brightness value lower than 30 then shows currently to show that picture belongs to dead color more than 65%
Tone, user can think that picture is not seen；Screen can be automatically adjusted at this time currently shows that the brightness value of picture keeps screen
More appropriate brightness.Such as when picture belongs to light tone tone, the brightness value institute of the first predetermined luminance threshold value can be will be greater than
The brightness value of corresponding pixel is adjusted to the first brightness value, and then reaches the effect for adjusting the brightness value that screen currently shows picture
Fruit, it is to be understood that the first brightness value should be less than the first predetermined luminance threshold value.It such as automatically will be more than the pixel of 200 brightness
Brightness regulation is to 120；Certainly adjusting screen currently shows the brightness value of picture to can also be automatically and screen is currently shown picture
The brightness value of all pixels point be adjusted to the first brightness value, the pixel intensity more than 120 brightness is such as adjusted to 120 automatically,
The pixel intensity that will be less than 120 brightness simultaneously is adjusted to 120；Currently the brightness value of the entire pixel of display picture all belongs at this time
In semi-tone, so that screen be made to automatically keep more appropriate brightness.
It certainly, can be automatically right by the brightness value institute less than the second predetermined luminance threshold value when picture belongs to dark-coloured tone
The brightness value for the pixel answered is adjusted to the second brightness value, and similarly, the second brightness value should be greater than the second predetermined luminance threshold value, such as
Automatically the pixel intensity by brightness lower than 30 is adjusted to 100, is also possible to that screen is currently shown to all pixels of picture automatically
The brightness value of point is adjusted to the second brightness value.
The present embodiment also provides a kind of adjusting method for adjusting screen and currently showing the brightness value of picture, and the adjusting method is logical
The brightness habit of overfitting user carries out Automatic Optimal.Specifically, as shown in figure 5, as Fig. 5 be according to the service condition of user from
