Abstract
This invention provides a simple projector system that can be operated by a user who is not an expert of image processing technology. The projector system comprises a projector (1), a personal computer (2), a mouse (3), and a calibration board (4). A checker flag pattern is added to the calibration board (4), and an intersection point serves as a marker. A cursor, which is projected from the projector (1) onto the calibration board (4), is used as an intuitive input interface. An operator, while seeing the cursor, operates the mouse (3), thereby placing the cursor onto the calibration marker. In this state, the operator clicks the mouse (3), thereby selecting the calibration marker. The operator then acquires the corresponding projection image coordinates on the basis of the selection instruction.
