摘要：
A projecting apparatus having a first projecting system for projecting an object to be projected to form an intermediate image, and a second projecting system for projecting the intermediate image formed by the first projecting system onto a screen. The first projecting system is adapted to distort the image of the object, and the second projecting system is adapted to correct the distorted image to project an enlarged image analogous to the object onto the screen.
