First Claim
1. A projector type display apparatus for applying light from a light source to a picture display device and projecting outgoing light from said picture display device onto a screen in an enlarged manner comprising:
- display device controller which controls said picture display device based on an input image signal;
a camera which captures an image projected on said screen;
detector which detects an area projected on said screen;
image size controller which changes, based on detection results from said detector, the captured image from said camera into a predetermined image size; and
extractor which extracts a person area in said captured image the size of which is changed by said image size controller;
wherein said display device controller controls so that an area on said image display device corresponding to said person area is substituted by predetermined data.

Abstract
There is provided a safe image display apparatus for projecting an image on a screen that can minimize a stimulus to eyes, retinae and optic nerves from projected light entering into the eyes directly. By comparing a displayed image captured by a camera with an input image signal, a changed area is detected as a difference area and, then, a projected image signal is generated wherein a picture area image signal in the input image signal that corresponds to this difference area is masked by a black signal. The obtained projected image signal is projected onto the screen.
