Terminal device may include the terminal device of mobile phone, tablet computer and smart television such as with camera module etc.
As shown in Figure 1, terminal device 1 according to the ... of the embodiment of the present invention may include camera unit 11 and processing unit
12。
Here, camera unit 11 can be realized by arbitrary camera module.Camera unit 11 can make in user
Image or video are obtained when being shot with terminal device 1.According to an embodiment of the invention, user's using terminal equipment 1 into
When row video conference or Video chat, camera unit 11 can obtain the first video when shooting.Here, the first video refers to
It is the original video data that camera unit 11 is obtained.
Processing unit 12 can be realized by arbitrary processor or microprocessor, and be based on preset program（Using）It holds
The scheduled processing of row.According to an embodiment of the invention, processing unit 12 can be handled the first video.For example, can be
When user opens Video chat application or video conference application, according to Video chat application or the setting of video conference application, certainly
Dynamic control process unit 12 handles the first video.Further, it is also possible to open Video chat application or video council in user
View switchs in application, providing specific video processing function in Video chat application or video conference application, and in video
When processing function switch is opened by user, 12 pair of first video is handled through the processing unit.Specifically, processing unit 12 with
Whether the presence of person taken picture is had in the picture of the picture of the first video of preset frequency monitoring and determining first video.Specifically,
Processing unit 12 can by obtaining the picture of the first video with scheduled frequency, and by arbitrary human body recognition technology or
Mode identification technology, which determines, whether there is person taken picture in the picture of first video（User）Presence.If processing unit 12 is true
There is the presence of person taken picture in the picture of fixed first video, then parameter of the processing unit 12 based on person taken picture judges whether to need to generate
Second video.Here, in the presence of having person taken picture in the picture that processing unit 12 determines the first video, processing unit
12 may further determine that quantity of the person taken picture in the picture of the first video（Number）, position（Region）And size（It is accounted for
The ratio of the picture of first video）.For example, if processing unit 12 determines that person taken picture is a people, processing unit 12 determines quilt
Position of the person of taking the photograph in the picture of the first video（Region）And size.If processing unit 12 determines person taken picture in the first video
Picture in position（Region）And size is suitable, then processing unit 12 judges without generating the second video.For example, if by
Position of the person of taking the photograph in the picture of the first video（Region）Positioned at the middle section of the picture of the first video, and person taken picture's is big
The small picture for being more than the first video 1/3 when, processing unit 12 judgement can not generate the second video.In addition, if processing is single
Member 12 determines that the quantity of person taken picture is more people, then position of the processing unit 12 based on whole person taken pictures in the picture of the first video
（Region）And size determines the need for generating the second video.For example, processing unit 12 determines that the quantity of person taken picture is more people,
Then processing unit 12 determines a box based on position of whole person taken pictures in the picture of the first video and size, here, side
The size and location of frame can be by the position of whole person taken pictures（Such as, it is located at the position of the person taken picture at edge）And size（Such as, exist
The size of maximum person taken picture in picture）It determines.Then processing unit 12 can be based on the size and location of identified box
To determine the need for generating the second video.For example, if the box of whole person taken picture's compositions is in the picture of the first video
Position（Region）Positioned at the picture of the first video middle section and its size be more than the first video picture 1/3 when, place
The reason judgement of unit 12 can not generate the second video.Here it is to be noted that it the size of the size and box of person taken picture
Threshold value is not limited to 1/3 described before.For example, the threshold value of the size of the size and box of person taken picture may be 1/4,1/2
Or other ratios.In the case where the determination of processing unit 12 need not generate the second video, processing unit 12 can will be produced
The first raw video sends another party of video conference or Video chat to.In this case, since processing unit 12 executes
Processing similarly to the prior art, which is not described herein again.
In addition, if processing unit 12 determines that position and size of the person taken picture in the picture of the first video are improper, then
The determination of processing unit 12 needs to generate the second video.
In this case, if the determination of processing unit 12 needs to generate the second video, processing unit 12 is based on shot
Quantity, position and the size of person generates the second video.
For example, if processing unit 12 determines that the quantity of person taken picture is a people, position of the processing unit 12 based on person taken picture
It sets and size intercepts at least part of the first video to generate the second video.For example, if the position of person taken picture is located at the
The left side of the picture of one video, then processing unit 12 is with the position of person taken picture（Such as, the axis of person taken picture or central area）It determines
The picture to be intercepted is located at the left side of the picture of the first video.In addition, size interception the of the processing unit 12 also according to person taken picture
At least part of one video generates the second video.Here, if size of the person taken picture in the picture of the first video（It is accounted for
The ratio of picture）Too small, then processing unit 12 intercepts the picture of the presumptive area around the person taken picture and uses the presumptive area
Picture generate the second video（Such as, it intercepts a part for each frame of the first video and the second video is generated based on the part）.
Here it is possible to determine the presumptive area according to the size of person taken picture, and the presumptive area be more than the size of person taken picture with comprising
Entire person taken picture.Furthermore, it is possible to the relationship of the presumptive area size and the size of person taken picture be determined according to experiment value, for example, should
Presumptive area can be less than or equal to twice of person taken picture's size.In this case, since the picture of the second video is first
A part for the picture of video, thus ratio of the person taken picture in the picture of the second video be more than person taken picture the first video picture
Ratio in face.In addition, according to another embodiment of the invention, if the size of person taken picture is suitable（More than the first video
The 1/3 of picture）, and when position is improper, the position that processing unit 12 can also be based only upon person taken picture intercepts the one of the first video
Part is used as the second video.In addition, the size in person taken picture is improper（Less than the 1/3 of the picture of the first video）, and position is closed
It is suitable（Picture center）When, the size that processing unit 12 can also be based only upon person taken picture intercepts a part for the first video as second
Video.
By the above-mentioned means, even if the position of person taken picture or size are improper in the first video, can also be generated newly
The second video picture（Larger ratio is simultaneously occupied in the centrally located region of person taken picture）In effectively protrude person taken picture, regard in this way
The each side of frequency meeting or Video chat will not be by unnecessary gibberish（Such as, furniture, all kinds of articles）It takes sb's mind off sth, thus
The use feeling of video conference or Video chat each side can be improved.
In addition, if processing unit 12 determines that the quantity of person taken picture is more people, then processing unit 12 can be based on whole quilts
The position for the person of taking the photograph and size intercept at least part of the first video to generate the second video.Here, in the picture of the second video
Comprising whole person taken pictures in face, and ratio of the person taken picture in the picture of the second video be more than person taken picture the first video picture
Ratio in face.Specifically, processing unit 12 can determine a box based on the position of whole person taken pictures and size, here,
Similar to the previous description, the size and location of box can be by the position of whole person taken pictures（Such as, it is located at the person taken picture's at edge
Position）And size（Such as, in picture maximum person taken picture size）It determines.In this case, if whole person taken pictures
（Box）Position be located at the first video picture left side, then processing unit 12 is with the position of whole person taken pictures（Such as, box
Axis or central area）The determination picture to be intercepted is located at the left side of the picture of the first video.In addition, processing unit 12 also according to
Whole person taken pictures（Box）Size intercept at least part of the first video and generate the second video.Here, if whole quilts
Size of the person of taking the photograph in the picture of the first video（It accounts for the ratio of picture）Too small, then processing unit 12 intercepts whole person taken pictures
（Box）The picture of the presumptive area of surrounding simultaneously generates the second video using the picture of the presumptive area.Here it is possible to according to complete
Portion person taken picture（Box）Size determine the presumptive area, and the presumptive area is more than whole person taken pictures（Box）Size with
Including whole person taken pictures.Furthermore, it is possible to determine the relationship of the presumptive area size and the size of whole person taken pictures according to experiment value
To provide suitable picture, for example, the presumptive area can be less than or equal to whole person taken pictures（Box）Twice of size.At this
In the case of kind, since the picture of the second video is a part for the picture of the first video, whole person taken pictures are in the second video
Picture in ratio be more than ratio of whole person taken pictures in the picture of the first video.In addition, it is according to the present invention another
Embodiment, if whole person taken pictures（Box）Size it is suitable（More than the 1/3 of the picture of the first video）, and position is improper
When, the position that processing unit 12 can also be based only upon whole person taken pictures intercepts a part for the first video as the second video.This
Outside, improper in the size of whole person taken pictures（Less than the 1/3 of the picture of the first video）, and position suitable（Picture center）When,
The size that processing unit 12 can also be based only upon whole person taken pictures intercepts a part for the first video as the second video.
By the above-mentioned means, even if the position of whole person taken pictures or size are improper in the first video, it can also be new
The picture of the second video generated（Larger ratio is simultaneously occupied in the centrally located region of person taken picture）In it is effectively prominent all shot
Person so that another party of video conference or Video chat will not disperse energy by other information, it is possible thereby to improve video conference
Or the use feeling of Video chat each side.
In addition, when carrying out video conference or Video chat, it might have other people and accidentally pass by terminal device
The coverage of camera unit 11, in this case, if the people that this is passed by is determined as person taken picture by processing unit 12,
Generated second video may then be had adverse effect on.In this case, according to one embodiment of present invention,
Wherein processing unit 12 further determine that the specific shot person in the first video the picture of the first video time whether be more than
First threshold.Include specific shot person if the time is more than the first threshold, in the second video that processing unit 12 generates.This
Outside, if the time is no more than first threshold, specific shot person is not included in the second video that processing unit generates.Specifically,
Each person taken picture that processing unit 12 can be directed in the picture of the first video calculates its time present in the first video,
Whether and it is more than first threshold to calculate it in the time of the picture of the first video.If processing unit 12 determines in all person taken pictures
Some person taken picture be less than first threshold in the time of the picture of the first video, then processing unit 12 is based on other shot
Quantity, position and the size of person come determine the need for generate the second video and need generate the second video when generate this second
Video.In addition, if processing unit 12 determine some person taken picture in all person taken pictures the picture of the first video time
More than first threshold, then quantity, position and size of the processing unit 12 based on specific shot person and other person taken pictures come
It determines the need for generating the second video and the when of generating the second video is being needed to generate second video.Here, first threshold can
To be determined based on experiment value, and can be in the range of 1~5 second.
By the above-mentioned means, avoiding since the personnel unrelated with video conference or video calling are taken into account and being based on
It generates the case where the second video.
After producing the second video, terminal device 1 generated second video can be sent to video conference or
Another party of video calling.In this case, terminal device 1 can also include communication unit（It is not shown）.Here, communication unit

The first video is obtained when shooting.Here, the first video refers to the original video data that camera unit 11 is obtained.Except this it
Outside, the first video can also be from other terminal devices with the progress video calling of terminal device 1 or video conference.
In step S202, whether to have in the picture of the picture of the first video of preset frequency monitoring and determining first video
The presence of person taken picture.
Specifically, processing unit 12 is in the picture of the picture of the first video of preset frequency monitoring and determining first video
Whether the presence of person taken picture is had.For example, processing unit 12 can by with scheduled frequency obtain the first video picture, and
It is determined by arbitrary human body recognition technology or mode identification technology and whether there is person taken picture in the picture of first video（With
Family）Presence.
In step S203, if it is determined that have the presence of person taken picture in the picture of the first video, then the parameter based on person taken picture
Judge whether to need to generate the second video.
Specifically, if having the presence of person taken picture, processing unit 12 in the picture of the first video of determination of processing unit 12
Parameter based on person taken picture（Such as, quantity, position and size etc.）Judge whether to need to generate the second video.For example, if
Processing unit 12 determines that person taken picture is a people, then processing unit 12 determines position of the person taken picture in the picture of the first video（Area
Domain）And size.If processing unit 12 determines position of the person taken picture in the picture of the first video（Region）And size is closed
Suitable, then processing unit 12 judges without generating the second video.For example, if position of the person taken picture in the picture of the first video
（Region）Positioned at the middle section of the picture of the first video, and when the size of person taken picture is more than the 1/3 of the picture of the first video,
The judgement of processing unit 12 can not generate the second video.In addition, if processing unit 12 determines that the quantity of person taken picture is more people, then
Position and size of the processing unit 12 based on whole person taken pictures determine the need for generating the second video.For example, processing unit
12 determine that the quantity of person taken picture is more people, then processing unit 12 determines a box based on the position of whole person taken pictures and size,
Here, the size and location of box can be by the position of whole person taken pictures（Such as, it is located at the position of the person taken picture at edge）And it is big
It is small（Such as, in picture maximum person taken picture size）It determines.Then processing unit 12 can be based on the big of identified box
Small and position determines the need for generating the second video.For example, if the box of whole person taken picture's compositions is in the first video
Position in picture（Region）Positioned at the picture of the first video middle section and its size be more than the picture of first video
When 1/3, the judgement of processing unit 12 can not generate the second video.Here it is to be noted that it the size and box of person taken picture
The threshold value of size be not limited to 1/3 described before.For example, the threshold value of the size of the size and box of person taken picture may be
1/4,1/2 or other ratio.In the case where the determination of processing unit 12 need not generate the second video, processing unit 12 can be with
Generated first video is sent to another party of video conference or Video chat.In this case, due to processing unit
Similarly to the prior art, which is not described herein again for 12 processing executed.In addition, if processing unit 12 determines that person taken picture regards first
Position and size in the picture of frequency is improper, then the determination of processing unit 12 needs to generate the second video.
In step S204, if it is determined that need to generate the second video, then the parameter based on person taken picture generates the second video.
Specifically, if the determination of processing unit 12 needs to generate the second video, ginseng of the processing unit 12 based on person taken picture
Number（Such as, quantity, position and size）Generate the second video.For example, step S204 may include：If it is determined that the number of person taken picture
Amount is that a people, the then position based on person taken picture and size intercept at least part of the first video to generate the step of the second video
Suddenly.For example, if the position of person taken picture is located at the left side of the picture of the first video, processing unit 12 is with the position of person taken picture
（Such as, the axis of person taken picture or central area）The determination picture to be intercepted is located at the left side of the picture of the first video.In addition, processing
Unit 12 intercepts at least part of the first video to generate the second video also according to the size of person taken picture.Here, if it is shot
Size of the person in the picture of the first video（It accounts for the ratio of picture）Too small, then processing unit 12 intercepts around the person taken picture
The picture of presumptive area simultaneously generates the second video using the picture of the presumptive area（Such as, the one of each frame of the first video of interception
Part simultaneously generates the second video based on the part）.Here it is possible to the presumptive area is determined according to the size of person taken picture, and should
Presumptive area is more than the size of person taken picture to include entire person taken picture.Furthermore, it is possible to determine that the presumptive area is big according to experiment value
The small relationship with the size of person taken picture, for example, the presumptive area can be less than or equal to twice of person taken picture's size.In this feelings
Under condition, since the picture of the second video is a part for the picture of the first video, person taken picture is in the picture of the second video
Ratio be more than ratio of the person taken picture in the picture of the first video.In addition, according to another embodiment of the invention, if by
The size for the person of taking the photograph is suitable（More than the 1/3 of the picture of the first video）, and when position is improper, processing unit 12 can also be based only upon
The position of person taken picture intercepts a part for the first video as the second video.In addition, the size in person taken picture is improper（Less than
The 1/3 of the picture of one video）, and position suitable（Picture center）When, processing unit 12 can also be based only upon the size of person taken picture
A part for the first video is intercepted as the second video.
By the above-mentioned means, even if the position of person taken picture or size are improper in the first video, can also be generated newly
The second video picture（Larger ratio is simultaneously occupied in the centrally located region of person taken picture）In effectively protrude person taken picture, regard in this way
The each side of frequency meeting or Video chat will not be by unnecessary gibberish（Such as, furniture, all kinds of articles）It takes sb's mind off sth, thus
The use feeling of video conference or Video chat each side can be improved.
In addition, step S204 can also include：If it is determined that the quantity of person taken picture is more people, then can be based on all shot
The position of person and size intercept at least part of the first video come the step of generating the second video.Here, in the second video
Picture in comprising whole person taken pictures, and ratio of the person taken picture in the picture of the second video is more than person taken picture in the first video
Picture in ratio.Specifically, processing unit 12 can determine a box based on the position of whole person taken pictures and size, this
In, similar to the previous description, the size and location of box can be by the position of whole person taken pictures（Such as, it is located at the shot of edge
The position of person）And size（Such as, in picture maximum person taken picture size）It determines.In this case, if whole quilts
The person of taking the photograph（Box）Position be located at the first video picture left side, then processing unit 12 is with the position of whole person taken pictures（Such as, side
The axis of frame or central area）The determination picture to be intercepted is located at the left side of the picture of the first video.In addition, processing unit 12 is also
According to whole person taken pictures（Box）Size intercept at least part of the first video and generate the second video.Here, if entirely
Size of the portion person taken picture in the picture of the first video（It accounts for the ratio of picture）Too small, then processing unit 12 intercepts all shot
Person（Box）The picture of the presumptive area of surrounding simultaneously generates the second video using the picture of the presumptive area.Here it is possible to according to
Whole person taken pictures（Box）Size determine the presumptive area, and the presumptive area is more than whole person taken pictures（Box）Size
To include whole person taken pictures.Furthermore, it is possible to determine the pass of the presumptive area size and the size of whole person taken pictures according to experiment value
System is to provide suitable picture, for example, the presumptive area can be less than or equal to whole person taken pictures（Box）Twice of size.
