PROJECTOR AND A CONTROL METHOD THEREOF, CAPABLE OF ADJUSTING BRIGHTNESS OF A PROJECTOR WITHOUT INCREASING OUTPUT OF AN EMBEDDED LIGHT SOURCE

摘要

PURPOSE: A projector and a control method thereof are provided to detect an image projected by a projector or brightness of a surrounding area, thereby keeping optimum brightness of the image.;CONSTITUTION: A brightness measuring unit(150) measures brightness. An image processor(120) converts an inputted image signal into an image to be projected. An optical unit converts an image into a projected light and projects it. The measured brightness is compared with predetermined reference brightness. If the measured brightness is brighter than the reference brightness, the optical unit reduces the size of an image due to the projected light.;COPYRIGHT KIPO 2010
