Add the fitness of ambient light illumination and video playback, improve the comfort of user's viewing.
In some cases, change due to the scene etc. of video content so that intelligent display device is current
The picture playing video occurs from dark to bright or from bright to dark situation, and the brightness of ambient light it is possible to regard
The brightness of frequency is no longer mated, therefore, and can be by the light adjusting method based on video parameter of above-described embodiment
Carry out the brightness of adjusting ambient lamp.
Specifically, described video parameter is the view data shown by currently playing video, described video parameter
Analysis result is the brightness data corresponding to view data, when described objective optics parameter is object brightness parameter；
Backlighting parameters analysis described in combination in described step 102 obtains the step of objective optics parameter and then may be used
Farther include:
Calculate the multiple view data obtained successively in described predetermined time interval (that is between certain time
The picture of multiple frames every interior acquisition) corresponding to the average brightness value of brightness data；
Wherein, described brightness data refer to according to view data calculated with frame picture can corresponding on
Brightness value, its calculation can be the frame picture by colored frame picture is converted to black and white, then
(typically from 0 to 255, white is 255 to intensity value ranges to gray value according to each pixel, and black is
0) average gray or the intensity-weighted meansigma methods of whole picture are calculated, then according to this meansigma methods and brightness

Utilize described intrinsic brilliance value to deduct the first predetermined luminance difference parameter, obtain object brightness parameter.
Here, the first predetermined luminance difference parameter can be zero or more than zero any number；When it is zero
Time, then the brightness of default contexts lamp should be equal with the brightness of currently playing video；And when it is more than zero,
Then the brightness of default contexts lamp is less than the brightness of currently playing video, and this design more conforms under normal circumstances
User watches custom during video；Preferably, the span of described first predetermined luminance difference parameter is
100～300lm.
Concrete, in order to ensure the change of the brightness flop more adaptive video content of ambient light, but unlikely
In the most all changing environment lamp brightness, described predetermined time interval is chosen as 5～10s.
Further, the described calculating multiple view data institutes obtained successively in described predetermined time interval
A kind of implementation that optimizes of the step of the average brightness value of corresponding brightness data can comprise the following steps that
The brightness data corresponding to multiple view data that will obtain successively in described predetermined time interval enters
Row contrast one by one (that is the brightness data of the image of each frame obtained successively bright with other images the most successively
Degrees of data contrasts)；
Exclude view data bright of more than brightness data and default eliminating ratio (such as 85%～95%)
Degrees of data difference is all higher than the view data of the second predetermined luminance difference parameter；Such as, at preset time intervals
Inside get the view data of 20 frames, the brightness data of the view data of each frame be the most respectively (100lm,
500lm、501lm、505lm、498lm、450lm、480lm、470lm、500lm、400lm、420lm、
900lm, 500lm, 500lm, 500lm, 480lm, 488lm, 512lm, 520lm, 469lm), false
If the second predetermined luminance difference parameter is 300lm, then can exclude the data of 100lm and 900lm, then
Using remaining brightness data as the basic data averaged, this eliminates the frame changing suddenly brightness
The picture impact on meansigma methods；
It is calculated average brightness value according to the brightness data corresponding to remaining view data；By this excellent
The average brightness value calculation changed, improves the brightness regulation of ambient light and the fitness of video content.
In order to build the atmosphere sense relevant to video, described lamp based on video parameter when watching video to user
Also can enter before the step 101 of the described video parameter persistently obtaining currently playing video of light regulation method
One step comprises the following steps:

(the most pre-from the locally extracted ambient light initialized optical parameter obtaining being associated with this video classification information
First at the locally stored ambient light initialized optical being associated with each classification (war, love, action etc.)
Parameter)；Described ambient light initialized optical parameter can include the numbers such as the brightness of ambient light, colour temperature, color
According to, such as, corresponding to the video of type of war, normal brightness, cool colour temperature, partially dark color can be used,
And corresponding to the video of love type, then can use dim brightness, warm colour temperature, partially red color etc.；
Described ambient light initialized optical parameter is sent to ambient light so that it is according to this by wireless communication mode
The optical parametric of ambient light initialized optical parameter regulation self.
So, it is adjusted according to initialized optical parameter by control ambient light so that ambient light is user
A kind of light atmosphere relevant to visual classification is provided, at the beginning of video playback, establishes a viewing for user
Keynote.
In some cases, owing to the scene in the different time sections of video content can change, in order to make
The lighting effects that obtaining ambient light is provided adapt with current scene, and it is based on video parameter that the present invention provides
The method that light adjusting method the most also can farther include to carry out light regulation according to scene.
Specifically, described video parameter includes the view data shown by currently playing video and/or is sent
Voice data, when described objective optics parameter includes target color temperature parameters and/or color of object parameter；
In described step 102 according to the video parameter analysis result in predetermined time interval, in conjunction with the described back of the body
Optical parameter analysis obtains the step of objective optics parameter and then can further include steps of
By described view data acquired at preset time intervals and/or described voice data with build in advance
Vertical multiple models of place (including the model of place in such as downtown area, bar, two people's air exercises, gunbattle etc.)
Mate successively；
Obtain and acquired described view data and/or the described voice data model of place that the match is successful
(such as bar scene), the described model of place that the match is successful is described video parameter analysis result；
From the locally extracted scene optical parametric obtaining being associated with the described model of place that the match is successful (such as
Corresponding to downtown area, more dim brightness, colder color, hepatic light etc. can be used)；And, in conjunction with
Scene optical parametric and described backlighting parameters, be calculated objective optics parameter.
By obtaining the described view data in predetermined time interval and/or described voice data, thus combine

Environment is narrow crowded so that health and head will occupy the most of area in image, by carrying out image
Analyze and i.e. can determine that current is the most crowded environment, can be corresponding with bar by it, the most also can be same
Time combine and judge that environment is the most noisy from current voice data and whether the background of lively rhythm occurs
Music, if the most noisy and background music lively rhythm, can be determined that the most substantially as bar；And under the scene of downtown area,
The generally degree of crowding of people can be less than the background music generally not havinging lively rhythm in bar, and audio frequency
And noisy degree is also below bar, therefore can the two be opened respectively, certainly by the analysis of image and audio frequency
The model of place of the two is also the most different；Additionally, when being in the scene of two people's air exercises, in view data generally
Only two humanoid images, and its translational speed is very fast, currently can broadcast by drawing the analysis of view data
The scene putting video is two people's air exercises, the most also can carry out the most accurately judging in combination with audio frequency；When
It is under the scene of gunbattle, usual audio frequency can parse the continuous of some more single-frequencies being spaced appearance
Scale (represent and occur that shot is that interval occurs every time, and every time appearance be all continuous several under shot) etc.
Deng, thus it is judged to gunbattle scene.
Setting up model of place according to similar above-mentioned scene decision procedure, model of place corresponds to view data
And/or voice data, mate scene time, too by obtain view data and/or voice data with
View data and/or the contrast of voice data in model of place are mated.
In order to the judgement making the scene of currently playing video is more accurate, the video parameter of required acquisition and brightness
Video parameter needed for contrast is compared, and needs more, it is therefore advantageous to, scene judge in the scheduled time
The span at interval is 30s～1min.
