Described step 2 is specifically as follows: chat person needs send expression or limb action image to the chat object in, start described camera head and carry out image and autodyne, after described camera head is taken and is finished with image data transmission in described communication terminal.
Described step 4 is specifically as follows: according to facial expression that is obtained or limb action, read corresponding cartoon character picture from described action expression cartoon picture library.
Described camera head can be the camera that communicates with one another with communication terminal.
Described communication terminal can be computer, mobile phone or PDA.
In technique scheme, the present invention is owing to utilize camera head to take chat person's the facial expression or the image of limb action, and with the image data transmission that obtained in communication terminal, communication terminal is by the analysis to view data, obtain current facial expression of chat person and limb action, thereby identical or akin facial expression and limb action are reflected by the cartoon picture, and this cartoon picture is sent to chat object place, thereby realized converting video image to process that the cartoon picture sends.Because the relative video image of cartoon picture, the data volume that needs to transmit is much smaller, even therefore both sides' bandwidth of chat is not enough, also can very smoothly the cartoon picture be sent to fast, glibly chat object place.And, therefore can reflect chat person's current state more exactly because the facial expression and the limb action of cartoon character all are to determine according to captured view data.Chat effect of the present invention not only is equivalent to original Video chat, and compares chat more vivid and interesting, transfer of data of original frequency and play smooth more.
Description of drawings
Accompanying drawing 1 is the flow chart of the method for a kind of video communication of the present invention.
Embodiment
With reference to figure 1, the method for a kind of video communication provided by the present invention specifically comprises the steps:
Step 1), the chat initial setting up;
Step 2), adopts camera head that chat person is taken, obtain view data, and import in the described communication terminal;

Step 5) sends to the chat object with the cartoon character that sets.
Below in conjunction with reaching two kinds of preferred embodiments the present invention is described in further detail.
Embodiment 1:
The method of the video communication that present embodiment provided is each facial expression key element and the limb action key element that a kind of image according to shooting is determined cartoon character, these key elements is made up the cartoon character that acquisition can accurately reflect chat person's current state again.It specifically comprises the steps:
Step 1), the chat initial setting up.Be specially:
At first, in communication terminal, set up an action expression cartoon picture library in advance, described action expression cartoon picture library internal memory contains some cartoon characters, facial key element picture and limb action key element picture when every kind of cartoon character all has different facial expressions of some width of cloth and limb action.As, can comprise Micky Mouse, MashiMaro, Kitty cat, Garfield, Winnie the Pooh or the like cartoon character in this action expression cartoon picture library.And each cartoon character, as MashiMaro, its facial key element comprises left and right eyes, left and right eyebrow, nose, lip etc., its limbs key element comprises front, rear, left and right four limbs, head, health etc.And every kind of key element all has its picture under different conditions, as for left eyebrow, then exist on the left eyebrow lift, left eyebrow in state diagram such as gather, lift on the interior angle of left eyebrow.
Then, by chat person's selected a kind of cartoon character from described action expression cartoon picture library.
At last, the communication between foundation and the chat object.
Step 2), adopts camera head that chat person is taken, obtain view data, and import in the described communication terminal.Be specially: start camera head and begin continuous shooting, described communication terminal receives the view data from camera head in real time.
Step 3) is analyzed the gained view data, identification chat person's facial expression or limb action.Be specially:
Described communication terminal can be analyzed the view data that every frame receives, also can guarantee under the continuous prerequisite of image, from the view data that is received, choose an auxiliary image data, analyze this width of cloth view data then, obtain chat person's facial expression or limb action every certain frame number.Present further developing along with science and technology, utilize captured view data, the technology of reference object being carried out face recognition and limb action identification is full-fledged, this technology is widely used in applications such as Film Animation shooting, virtual image design, security monitoring, therefore this technology is the prior art in this area, is not described in detail here.
Step 4), facial expression or limb action that the facial expression that obtained or limb action are used to be provided with cartoon character.Be specially:
