The present invention relates to a project system in which the screen size of such as an electronic bulletin board, an electronic note, etc. can be used in various fashions by selectively using a standardized angle image and a wide angle image. The project system according to the present invention comprises an electronic pen (10), a projector (20), and a terminal (30). The projector (20), comprises: an image projection unit (23) for generating an image; an optical unit (21) for projecting the image generated in the image projection unit (23) to the outside; a communication unit (22) for wired or wireless communicating with a terminal (30); an electronic pen location tracking unit (24) for receiving an infrared oscillating signal generated according to the movement of an electronic pen (10) and seeking the location of the electronic pen (10); a camera (26) for decoding an image (40) projected from the optical unit (21); and an image processing unit (27) for comparing the image decoded in the camera (26) and an image transmitted from the terminal (30). The camera (26) comprises a standard lens (26a) for decoding a standardized angle image (40a) and a wide-angle lens (26b) for decoding a wide angle image (40b). The optical unit (21) comprises a standard lens (21a) for realizing a standardized angle image (40a) and a wide-angle lens (26b) for realizing a wide angle image (40b), and projects the image generated in the image projection unit (23) in the form of a standardized angle image (40a) or a wide angle image (40b). |
