Abstract: Provided are a method and apparatus for setting an electronic blackboard system. In response to a user input to a control apparatus requesting setting of the electronic blackboard, sensitivity of an IR camera is set so that visible rays are detected. A projector projects an image with a presentation region and a first guider therein for alignment. The IR camera transmits a first captured image of the presentation region, including at least a portion of the first guider, to the control apparatus. The projector is then controlled to project to the screen at least a portion of a second guider corresponding to the first guider in the first image received from the IR camera. The user may then make positional adjustments to the IR camera or projector using the second guider.
