Parameter value corresponding to configuration parameter, the camera to the machine carries out parameter configuration.
Step 106, mobile terminal are compressed coding to the view data that camera is gathered.
After mobile terminal configuration completes camera parameter, you can start to obtain the view data of camera collection.In order to
The transmitting efficiency of view data is improved, the mobile terminal can first use default compaction coding method, to the image of the collection
Data are compressed coding.
Example, mobile terminal can be a kind of YUV (color codings by the raw image data accessed by camera
Method) form data.Because the data volume of every frame yuv data is very big, offered load when being transmitted to the view data
It is higher, so needing first to be compressed to improve the real-time of data transfer between TV and mobile terminal using compressed encoding
Property.It is for instance possible to use H.264 compaction coding method or H.265 compaction coding method is compressed to the data of the yuv format
Coding.
So that resolution ratio is for 640 × 480 image as an example, the size of the data of a frame yuv format is 640 × 480 × 3/2=
450 kilobytes (KB), if the mobile terminal data that 25 frames are sent to TV per second, the data volume transmitted needed for a second is
450 × 25=11250KB=11 Mbytes (MB).And H.264 the data compression rate of compaction coding method is about 200：1, because
This using this after H.264 compaction coding method is compressed coding to view data, the number of transmission needed for mobile terminal each second
56KB can be compressed to according to amount；And H.265 compaction coding method is the further optimization to H.264 compaction coding method, its pressure
Contracting performance is better than H.264 compaction coding method, and the compression effectiveness to view data is more preferable.
Step 107, mobile terminal send the view data after compressed encoding to TV.
Specifically, mobile terminal can be sent by the view data after compressed encoding by wireless network to the TV.
Example, the mobile terminal can be by transmission control protocol (TransmissionControlProtocol, TCP), number of users
According to datagram protocol (UserDatagramProtocol, UDP) or real time streaming transport protocol
Agreements such as (RealTimeStreamingProtocol, RTSP) sends the view data.
Step 108, TV are decoded according to default decoding algorithm to the view data that mobile terminal sends.
In embodiments of the present invention, TV by utilizing camera interface receive the mobile terminal send view data after,
Need the figure for first being received to this according to default decoding algorithm (corresponding with the compaction coding method that mobile terminal is used)
As data are decoded.
Example, TV can use H.264 coding/decoding method or H.265 coding/decoding method method is carried out to the data for receiving
Decoding, obtains the data of yuv format.
The color coding that step 109, TV are supported the color coding form of decoded view data by mobile terminal
Form is converted to the coded format of TV support.
By the color coding form that mobile terminal and TV are supported is typically different, and different mobile terminals is supported
Color coding form it is also different.When TV directly displays the view data of mobile terminal transmission, it is possible that color
The phenomenons such as display exception.For example, the red in original digital image data may be shown as blueness.Therefore, in order to ensure picture number
According to normal display, TV needs to change the color coding form of view data.
Wherein, the color coding form that mobile terminal is supported can generally include following five kinds：
COLOR_FormatYUV420Planar；
COLOR_FormatYUV420PackedPlanar；
COLOR_FormatYUV420SemiPlanar；
COLOR_FormatYUV420PackedSemiPlanar；
COLOR_TI_FormatYUV420PackedSemiPlana。
Understood with reference to above-mentioned steps 102, after TV sets up network connection with mobile terminal, you can get the mobile terminal
The color coding form supported.Further, after TV gets the view data transmitted by the mobile terminal, Ke Yixian
Determine the object format that the machine is supported, the color coding lattice that the decoded view data is supported by mobile terminal again then
Formula is converted to the coded format of TV support.
Example, the setPreviewFormat that the VirtualCamera classes of TV can be called by upper layer application
(intpixel_format) the color coding form required for interface determines the upper layer application, then again to the view data
Color coding form is changed.Afterwards, the TV can be write to temp directory the data of the yuv format after changing
A temporary file VirtualCameraData.yuv in, data in the VirtualCameraData.yuv files can be with
Ceaselessly rewritten by the view data of new yuv format.
View data after step 110, the conversion of TV Show Color coded format.
In embodiments of the present invention, TV can continue to read the image in this document virtualCameraData.yuv
Data, and show the view data after color coding form conversion.
It should be noted that the sequencing of the step of call method of camera provided in an embodiment of the present invention can enter
The appropriate adjustment of row, step according to circumstances can also accordingly be increased and decreased, and for example step 102 can also be performed after step 104.
