An interactive document camera system includes a document camera, a display panel, and a handwriting sensor module. The document camera can simultaneously output an image of an object and a handwriting input obtained from the handwriting sensor module. The inactive document camera system further includes a computer system so that an operating image provided by the computer system can be simultaneously outputted, and a handwriting data corresponding to the handwriting input can be recorded in the computer system. The interactive document camera includes an image-sensing and processing unit, different connecting interfaces and an image synthesizer. The different connecting interfaces are selectively connected to and communicated with a display panel, a handwriting sensor module or a computer system.
