Image processing apparatus and method of wired / wireless telephone using a computer {APPARATUS AND METHOD FOR IMAGE PROCESSING IN TELEPHONE USING COMPUTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus and method for a wired / wireless telephone, and more particularly, to receive image and communication data, which is a combination of image and voice, transmitted through a public network, using a connected computer, and synthesizes input voice and images. The present invention relates to an image processing apparatus and method for a wired / wireless telephone using a computer that can transmit image communication data including the same through a public network.

In general, when communicating with others in remote locations, voice communication using only voice and video communication using voice and image are used.

In particular, in recent years, video communication has been rapidly developed due to the development of Internet and wireless communication technologies. A public payphone and a video communication terminal used for the Internet and wireless communication that enable such video communication are provided with a monitor that can identify the other party and a small camera that can take a picture of the talker on one side. When you do, the picture of the talker looking at the monitor is taken by the camera installed on one side and transmitted to the talker.

Accordingly, in the conventional video communication method, video and video communication using wireless and the Internet transmits images through a monitor mounted on a computer and a camera for a computer or through an LCD screen of a wireless communication terminal. There is no problem in receiving video communication, but video communication using a general public telephone network requires the use of a special video communication terminal.
