Abstract

A scanning device which is connected to a projector for displaying the scanned images. The scanning module scans documents and the scanned images are processed by a CPU controlled by the user interface. Thus, the signal process unit, memory and output unit can be activated. The scanned images are processed by the signal process unit, the memory, and a video buffer. Then, the scanned images are transferred to a projector via the output unit. The connection between the projector and the scanner is simplified and convenient for the users.
