ABSTRACT:
The present invention relates to an image projection system whereby a display position of a pointer on a projected image can be easily controlled from a location separated from the main control means. The system comprises a liquid crystal projector, a personal computer for controlling the liquid crystal projector to display a pointer on a projected image in accordance with an operation signal from a main operating section and a predetermined program, and a remote controller for the liquid crystal projector.The remote controller comprises a pointing device and a light emitting portion for wirelessly transmitting an operation signal.The liquid crystal projector comprises a light receiving portion for receiving tirelessly transmitted signals. The personal computer controls the liquid crystal projector to transfer the received signals to the personal computer and further controls the display position of the pointer according to the transferred pointing device operation signals.
