Abstract: PURPOSE: A stream image mixing apparatus is provided to combine partial images of stream type obtained by plural cameras and to mix a wide view image with high speed, thereby enabling a user positioned at a remote site to view a desired screen at real time through panning, tilting and zooming and the like. CONSTITUTION: Plural image input terminals(10) include an image capture board, respectively, receive images inputted from the plural cameras(1) arranged with horizontal or vertical directions and transmits the received image to a stream server(20). The stream server comprises a stream distribution module, calculates a transformation matrix(M) for defining the corresponding relation between the cameras by the stream distribution module and transmit the calculated transformation matrix to a client terminal(30). The stream server also analyzes user selection location data transmitted from the client terminal, and selects and transmits the stream images corresponding to the location data. The client terminal(30) includes a mosaic module(200), analyzes the user input information by the mosaic module, transmits the user selection location information to the stream server, mixes the stream images transmitted from the stream server, performs a texture mapping on a chassis polygon and then displays the mapping result.
