Abstract: Disclosed is an electronic whiteboard system in which a screen-changing operation works on changing screen of the whiteboard, at the same time, works on creating a new page on a personal computer (PC). In response to the screen-changing operation, the whiteboard changes the screen and transmits a screen-changing code to the PC. Received the screen-changing code, the PC automatically creates a new page. Similarly, in response to scanning operation, the whiteboard transmits a scanning code and a scanned image to the PC. Received the scanning code and the scanned image, the PC creates a new page and stores the scanned image at the same time.
