beam projector and method for automatically calibrating a image using the beam projector

摘要

PURPOSE: A beam projector and an automatic image correcting method using the same are provided to change the size and shape of an image projected by a beam projector. CONSTITUTION: An automatic image correcting method using a beam projector is as follows. The attachment location of a plurality of sensors is sensed(S910). The shape and size of a domain defined by the attachment location of a plurality of sensors are produced by using the attachment location of a plurality of sensors(S920). An output image is revised by using the shape and size of the domain(S930). A test image is projected on a screen. A sensor signal corresponding to the test image is sensed.
