receiving, at a communication device, a first video frame of a communicating party which is in a communication with the communication device;

obtaining, at the communication device, a second video frame of the local party through a camera;

identifying, at the communication device, an outline of a user in the second video frame;

cropping, at the communication device, a part of the second video frame beside the outline of the user to generate a third video frame which includes only images inside the outline of the user;

combining, at the communication device, the third video frame with the first video frame of the communicating party to generate a fourth video frame; and

displaying, at the communication device, the fourth video frame.

2 . The method according to claim 1 , further comprising:

obtaining, at the communication device, a fifth video frame of the local party through an infrared imaging device;

identifying, at the communication device, an outline of a user in the fifth video frame;

determining, at the communication device, a position where the outline of the user in the fifth video frame; and

identifying, at the communication device, an outline of a user in the second video frame based on the position where the outline of the user in the fifth video frame and a relationship between the camera and the infrared imaging device.

3 . The method according to claim 1 , further comprising:

determining, at the communication device, a corrected outline of the user in the second video frame by boundary point identification.

4 . The method according to claim 3 , wherein the boundary point identification is performed by:

obtaining, at the communication device, pixel values of each points in the second video frame; and

determining, at the communication device based on change of pixel values.

5 . The method according to claim 1 , further comprising:

transmitting, from the communication device, the fourth video frame to the communicating party.

6 . The method according to claim 1 , further comprising:

combing, at the communication device, the third video frame and the first video frame based on a video synthesis technology which includes background transparency and soft edges.

7 . The method according to claim 1 , wherein the first video frame includes only images inside an outline of a user in the first video frame.

8 . The method according to claim 7 , further comprising: combining, at the communication device, the first video frame and the third video frame with a predefined background video frame to generate a fifth video frame to be outputted.

9 . A communication method, comprising:

receiving, at a communication device, at least one first video frame of at least one communicating party which is in a communication with the communication device, wherein each first video frame is corresponding to one of the at least one second party;

identifying, at the communication device, an outline of a user in the first video frame;

cropping, at the communication device, a part of the each video frame outside the outline of the user to generate at least one second video frame;

obtaining, at the communication device, a third video frame of the local party through a camera;

combining, at the communication device, the at least one second video frame with the third video frame to generate a fourth video frame; and

displaying, at the communication device, the fourth video frame.

10 . The method according to claim 9 , further comprising:

transmitting, from the communication device, the fourth video frame to the at least one communicating party.

11 . The method according to claim 9 , wherein the identification of the outline of the user in the first video frame based on boundary point identification.

12 . The method according to claim 9 , wherein the third video frame includes only images inside an outline of a user in the third video frame.

13 . A communication device, comprising:

a storage unit configured to store instructions; and

a processor configured to execute instructions to cause the processor to:

receive a first video frame of a communicating party which is in a communication with the communication device;

obtain a second video frame of the local party through a camera;

identify an outline of a user in the second video frame;

crop a part of the second video frame beside the outline of the user to generate a third video frame which includes only images inside the outline of the user;

combine the third video frame with the first video frame of the communicating party to generate a fourth video frame; and

display the fourth video frame.

14 . The communication device according to claim 13 , wherein the instructions further cause the processor to:

obtain a fifth video frame of the local party through an infrared imaging device;

identify an outline of a user in the fifth video frame;

determine a position where the outline of the user in the fifth video frame; and

identify an outline of a user in the second video frame based on the position where the outline of the user in the fifth video frame and a relationship between the camera and the infrared imaging device.

15 . The communication device according to claim 13 , wherein the instructions further cause the processor to:

transmit the fourth video frame to the second party.

16 . The communication device according to claim 13 , wherein the communication device is a fixed phone or a mobile phone.

17 . The communication device according to claim 13 , wherein the communication device is an electronic device which includes a communication unit.

18 . The communication device according to claim 17 , wherein the communication unit includes an instant message system.

19 . The communication device according to claim 17 , wherein the electronic device is a computer or a television.

20 . The communication device according to claim 13 , wherein the instructions further cause the processor to:

determine a corrected outline of the user by boundary point identification.
