Abstract: A video communication device includes a video communication device body; a camera fitted to the video communication device body to record images of an object; at least one detection unit fitted to the video communication device body to detect the object according to a predetermined condition; and a camera rotation angle adjuster fitted to the video communication device body to adjust a rotation angle of the camera according to detection data from the detection unit so that the camera automatically tracks a position of the object when the object moves. The moving object can be located through a detection unit, such as a voice sensor, a codec, a color sensor and an IR sensor, and be automatically tracked by suitable adjustment of the rotation angle of a camera. A wide angular field is ensured and video telephony quality is improved.

Abstract: A video telephony terminal and an image transmission method thereof are provided. During video communication, the video telephony terminal generates a still image having a desired pattern in a user-desired region and provides a terminal of another party with an image achieved by synthesizing the generated still image with an image captured by a built-in camera. Upon establishing video communication, a change to the desired pattern in the user-desired region of the camera-captured image can be made quickly, or a desired message can be inserted into the captured image and can be transmitted in real time.
