<p>A technique of superimposing a decorating effect on the projected image independently of the performance of an image input device. A projection display has a decorating effect memory for storing therein decorating effect data representing a decorating effect image used for decorating an arbitrary image, an image decorating section for generating decorated image data representing a decorated image by superposing the original image represented by input image data on the decorating effect image, an optical modulating means driven for every picture element according to the decorated image data, and an optical system for projecting on a screen the decorated image formed by driving the optical modulating means. A projection image device superimposes a decorating effect on the projected image independently of the performance of an image input device.</p> |
