In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of played in full screen methods.The core of present embodiment is: determining view
The play area of frequency；Wherein, play area are as follows: for effectively showing the region of video content；Obtain the picture ratio of play area
Example；According to aspect ratio, played in full screen is carried out to play area.
In present embodiment, due to play area here are as follows:, therefore, should for effectively showing the region of video content
Play area inevitable does not include that can not effectively show the regions such as the black surround of video content, so as to be based only upon the play area into
Row played in full screen allows to show video content more in large area.
The realization details of the played in full screen method of present embodiment is specifically described below, the following contents is only side
The realization details of offer is just provided, the necessary of this programme is not implemented.
The flow chart of played in full screen method in present embodiment is as shown in Figure 1, comprising:
Step 101, the play area of video is determined.
Referring to fig. 2, therein 11 play area is indicated, i.e., for effectively showing the region of video content, 12 expressions can not
Effectively show region of video content, such as decorative pattern filling region, filled black region, white filling region etc..
Specifically, fuzzy diagnosis can be carried out to several frames of video, respectively obtains the non-play area of several frames, then
According to non-play area, the play area of video is determined.Wherein it is possible to by convolutional neural networks model to several frames of video
Carry out fuzzy diagnosis.
In one example, any one frame that can be randomly selected in video carries out fuzzy diagnosis, and non-broadcasting can be obtained
Region, removing the part other than non-play area is play area.
In another example, fuzzy diagnosis can be carried out respectively to multiple frames in video.Assuming that the number of frame herein
Amount is 3, then after carrying out fuzzy diagnosis to these frames, can respectively obtain 3 non-play area, and then can be 3 according to this
Non- play area determines 3 play area of video.Assuming that the coordinate data on four vertex of this 3 play area is respectively as follows:
(a1, a2, a3, a4), (b1, b2, b3, b4), (c1, c2, c3, c4).Can then calculate separately a1, b1, c1 average value A, a2,
The average value C of the average value B, a3, b3, c3 of b2, c2 and the average value D of a4, b4, c4, by (A, B, C, D) as determination
Play area.May dimensionally there be small difference due to carrying out the play area that fuzzy diagnosis obtains respectively to different frame
Not, therefore, in four vertex by calculating separately each play area, the average value mode of the data on each vertex determines broadcast area
Domain, the accuracy for the play area that can be improved.
Wherein, in the above example, can also be in four vertex for calculating separately each play area, the data on each vertex
Average value before, calculate separately difference between a1, b1, c1, the difference between a2, b2, c2, the difference between a3, b3, c3,
And the difference between a4, b4, c4, after play area corresponding to the biggish coordinate data of difference is deleted, then calculate remaining
Each play area four vertex in, the average value of the data on each vertex.By differing greatly in deletion with each play area
Play area after, then calculate in four vertex of remaining each play area, the average value of the data on each vertex, can be to avoid
The play area to differ greatly with each play area has an impact the average value of the data on each vertex finally calculated, thus
The accuracy for the play area that can be further improved.
It in other examples, can also be multiple to what is obtained after carrying out fuzzy diagnosis respectively to multiple frames in video
Play area takes the mode of intersection, and to determine the play area of video, the present embodiment is not especially limited this.
Step 102, the aspect ratio of play area is obtained.
Wherein, aspect ratio mentioned here can be the width and length ratio of play area, be also possible to broadcast area
The ratio between the length and width in domain is not especially limited herein.
Step 103, according to aspect ratio, played in full screen is carried out to play area.
Specifically, it is assumed that the aspect ratio of play area is 16:9, shows that the ratio of the display interface of equipment is also 16:
9, then it is played in full screen truly to the played in full screen that play area carries out；Assuming that the aspect ratio of play area is
16:9, and show that the ratio of the display interface of equipment is 18:9, then in the amplification process of played in full screen, it can be set when detection
When into the length of play area, width, any one is equal to the corresponding length of display interface, width, then do not continue to amplify,
And remaining area is filled, for example carry out filled black.
It is according to the entire displaying interface of video (including Fig. 2 it will be understood by those skilled in the art that in the related art
In 11 and 12) carry out played in full screen, therefore, can be still in the video after carrying out played in full screen if video itself includes 12
So include 12, leads to not show video content more in large area.And in the present embodiment, in the aspect ratio of play area
Under the ratio unanimous circumstances of display interface, if video itself includes that can not effectively show the regions such as the black surround of video content,
Then by carrying out played in full screen to play area, the purpose of played in full screen truly can achieve.In play area
In the case that the ratio of aspect ratio and display interface is inconsistent, video content can be caused to be distorted not influencing video quality
In the case where, carrying out played in full screen to the full extent to play area (ought detect the length of play area, appoint in width
It when anticipating one equal to the corresponding length of display interface, width, then does not continue to amplify, and be filled remaining area).
It is not difficult to find that a kind of played in full screen method that present embodiment provides, by first determining for effectively showing video
Then the play area of content obtains the aspect ratio of play area again, and according to aspect ratio, carry out to play area full frame
It plays.Due to play area here are as follows: for effectively showing the region of video content, therefore, which is not wrapped necessarily
The regions such as the black surround of video content can not effectively be shown by including, and carry out played in full screen so as to be based only upon the play area, so that
Video content can be shown more in large area.
Second embodiment of the present invention is related to a kind of played in full screen method.Present embodiment and first embodiment are substantially
It is identical, the difference is that: in the present embodiment, another specific implementation for determining play area is provided, it can be with
The realization for allowing the process of determining play area flexible and changeable.
The flow chart of played in full screen method in present embodiment is as shown in Figure 3, comprising:
Step 201, it detects in several frames of video, adjacent two frame whether there is same area.
Referring to fig. 4, it is illustrated in figure 4 the schematic diagram of adjacent two frame, what the solid black areas in adjacent two frame indicated
The as same area of adjacent two frame.Wherein it is possible to being determined as follows adjacent two frame whether there is same area,
Flow chart is as shown in Figure 5, comprising:
Sub-step 2011 obtains the corresponding display parameter value of each frame in several frames.
Wherein, display parameter value mentioned here can be but be not limited to: pixel, color value are not especially limited herein.
Sub-step 2012 judges in adjacent two frame whether the difference of the display parameter value in same position is less than preset value.
If being less than preset value, enter sub-step 2013, otherwise, into sub-step 1024.
In one example, it is assumed that 100 frames for getting video are indicated with digital 1-100, also, adjacent digital institute
Corresponding two frame is adjacent two frame.Then judge in the 1st frame and the 2nd frame, whether the difference of the display parameter value in same position is small
In preset value, if being less than preset value, that is, it can determine that there are same areas for adjacent two frame.Then the 3rd frame and the 4th frame be may determine that
In, in the 4th frame and the 5th frame ... until obtaining in the 99th frame and the 100th frame, the difference of the display parameter value in same position
Whether the judging result of preset value is less than.
In the above example, if in the 1st frame and the 2nd frame, the difference of the display parameter value in same position is less than preset value,
It then can determine that there are same areas for adjacent two frame, the same area be denoted as region 1 herein.Similarly, if in the 2nd frame and the 3rd frame,
There are same areas, then judge whether the same area is identical as region 1, if they are the same, are then denoted as region 1, otherwise, are denoted as region
2.If in the 3rd frame and the 4th frame, there are same areas, then judge whether the same area and region 1 or region 2 are identical, and if area
Domain 1 is identical, then is denoted as region 1, if identical as region 2, is denoted as region 2, otherwise, is denoted as region 3 ... until obtaining to
In 99 frames and the 100th frame, if there are same areas, and same area judgement identical with which predetermined region
As a result.Assuming that existing same area is that the quantity of the frame in region 1 is 70, existing if counting in 100 frames of video
Same area is that the quantity of the frame in region 2 is 2, and the quantity there are the frame that same area is region 3 is 2, since there are phases
The 70% of the quantity for the frame for accounting for counting by the quantity of the frame in region 1 with region is greater than preset threshold value (such as 50%), then
It can determine that the region 1 is that can not effectively show therefore the region of video content removes the region other than the region 1, as
The play area of determining video.Similarly, since there are the quantity for the frame that same area is region 2, and there are same areas
Quantity for the frame in region 3 is few, hence, it can be determined that region 2 and region 3 are not belonging to effectively show the area of video content
Domain.
Although it should be noted that being to judge since the 1st frame and the 2nd frame in the above example, until the 30th frame end
Sequence is successively judged.However the application does not carry out any restriction to judgement sequence, as long as being to the judgement of adjacent two frame
It can.
Sub-step 2013 determines that there are same areas for adjacent two frame.
Sub-step 2014 determines that same area is not present in adjacent two frame.
Step 202, it counts in several frames, there are the quantity of the frame of same area.
Step 203, according to there are the quantity of the quantity of the frame of same area and several frames of video, video is determined
Play area.
Step 202 and step 203 are illustrated here in connection with an example.If counting in 100 frames of video, deposit
It is 60 in the quantity of the frame of same area, then the quantity that there is the frame of same area accounts for the quantity of counted frame
60%, then it can determine that same area here is that can not effectively show therefore the region of video content removes the same zone
Region other than domain, the as play area of determining video.
Step 204, the aspect ratio of play area is obtained.
Step 205, according to aspect ratio, played in full screen is carried out to play area.
Since step 102, the step 103 in step 204, step 205 and the first embodiment in present embodiment are big
Cause identical, to avoid repeating, details are not described herein again.
It is not difficult to find that a kind of played in full screen method that present embodiment provides, provides a kind of tool of determining play area
Body implementation, the realization that the process of determining play area can be allowed flexible and changeable.
Third embodiment of the invention is related to a kind of played in full screen method, present embodiment and first embodiment or second
Embodiment is roughly the same, the difference is that: in the present embodiment, provide another specific reality for determining play area

When the first parameter threshold, may indicate that the adjacent rows be it is discontinuous, therefore, using the line of demarcation between the adjacent rows as
First the first transverse edge；Continue from left to right, in the same way, to determine second the first transverse edge.Wherein, first
Parameter threshold can be 10%, when the similarity between the information of adjacent rows is less than 10%, may indicate that the adjacent rows
It is discontinuous.
In one example, from left to right, parameter information can be examined by column using the upper left corner of target frame as vertex
It surveys, and obtains the similarity between the parameter information that adjacent two arrange, when the similarity between the parameter information of adjacent two column is less than
When the second parameter threshold, may indicate that this it is adjacent two column be it is discontinuous, therefore, using this it is adjacent two column between line of demarcation as
First the first vertical edges；Continue from left to right, in the same way, to determine second the first vertical edges.Wherein, second
Parameter threshold can be 10%, when the similarity between the information of adjacent two column is less than 10%, may indicate that the adjacent rows

Whether user display requirement to play area is received；If receiving display requirement of the user to play area, according to aobvious
Show that requirement plays out play area；Otherwise, played in full screen is carried out to play area.Alternatively, being carried out entirely to play area
After screen plays, if receiving display requirement of the user to play area, require to play out play area according to display.
Wherein, display requirement mentioned here can be but be not limited to: amplified play area accounts for the ratio of entire display interface.
In one example, user A is watching the video content after carrying out played in full screen to play area, if user
B looks for user A to chat, and user A had not only want to chat with user B, but also wants to continue to watch video content, then, user A can be to terminal
Equipment sends the display requirement to play area, for example may is that amplified play area accounts for the 2/3 of entire display interface,
In this way, terminal device can be required according to display, control play area accounts for the 2/3 of entire display interface.Wherein, by broadcast area
During domain is adjusted to account for the 2/3 of entire display interface, play area can be with normal play.Play area is being adjusted to account for
Behind the 2/3 of entire display interface, user can arbitrarily adjust play area the location of in display interface, in order to user
The application program of display interface (i.e. remaining 1/3 display interface) in addition to play area is operated, for example, can be with
Wechat is opened, and the chat window of wechat is adjusted to the display interface in addition to play area, in this way, user can be on one side
Video content is watched, is chatted on one side with user B.
It should be noted that present embodiment changing of being also possible to make on the basis of second or third embodiment
