Abstract:
1. A projector type display apparatus for applying light from a light source to a reflecting type picture display device and projecting outgoing light from said reflecting type picture display device by a projection lens comprising: a video processor which generates a display picture information; a camera interface which takes in a captured image captured by a camera and outputs as captured image information; an image size controller which outputs an area determined as a projected image as a displayed area extraction image; an image comparator which generates disagreement information at least in a part of a person area by comparing the image information of the displayed area extraction image with the information of projected combined image; a difference area generator which generates differential area information based on the disagreement information; a mask image generator which generates masked image information based on the differential area information; and an image signal combining unit which superposes the masked image information on the displayed image information and outputs the displayed image information as the information of newly projected combined image information.
