Claim One:
1. A Universal Serial Bus device applied to webcams, the Universal Serial Bus device comprising: at least two input interfaces, each input interface being used for coupling to an image sensor, wherein the at least two input interfaces are used for receiving at least two images generated by at least two image sensors coupled to the at least two input interfaces and identification bits corresponding to the at least two image sensors, wherein the at least two input interfaces are not Universal Serial Bus interfaces, and the identification bits in turn received by the at least two input interfaces are used for making the at least two images be corresponding to each other when the at least two images generated by the at least two image sensors are used for synthesizing three-dimensional images; an input interface control unit coupled to the at least two input interfaces for determining whether the at least two images are used for synthesizing the three-dimensional images and controlling a received sequence of the at least two images and the identification bits when the at least two input interfaces receive the at least two images and the identification bits in response to a determination that the at least two images generated by the at least two image sensors are used for synthesizing the three-dimensional images; a central processing unit for determining whether the at least two images are used for synthesizing the three-dimensional images and controlling the received sequence of the at least two input interfaces and the identification bits when the at least two input interfaces receive the at least two images and the identification bits in response to a determination that the at least two images are not used for synthesizing the three-dimensional images; an image input interface; and a single Universal Serial Bus physical layer, wherein the image input interface is coupled between the input interface control unit and the single Universal Serial Bus physical layer for receiving and transmitting the at least two images generated by the at least two image sensors and the identification bits corresponding to the at least two image sensors to the single Universal Serial Bus physical layer; wherein the Universal Serial Bus device only uses the single Universal Serial Bus physical layer to connect with a host which is outside the Universal Serial Bus device and the host receives the at least two images and the identification bits corresponding to the at least two image sensors only via the single Universal Serial Bus physical layer, wherein the host is capable to identify that each of the at least two image is generated by which one of that at least two image sensors according to the identification bits; wherein the at least two input interfaces, the input interface control unit, the image input interface, and the single Universal Serial Bus physical layer are physically integrated into the Universal Serial Bus device.
