Projector with correction circuit

Abstract

Abstract PURPOSE:To avoid white balance adjustment and uneven brightness in an excellent way by implementing white balance adjustment and brightness adjustment on a projection face respectively based on color information and brightness information of the projection face. CONSTITUTION:A projector 1 has an information detection section (projection face information detection means) 3 and a projector main body 5. The information detection section 3 detects on color information and brightness information on a projection face S onto which a video image is projected from the projector 5. Based on the color information and brightness information detected by the information detection section 3, the white balance adjustment and brightness adjustment of a video signal V are respectively implemented by a correction circuit 7. Thus, excellent white balance adjustment is attained and uneven brightness is avoided independently of the color or contrast of the projection face.
