Abstract
An overhead projector for projecting an image onto a screen includes a light-to-light converter for recording an image therein and reproducing the recorded image therefrom. A first light source applies first light to read an image from a subject copy and record the image in the light-to-light converter under a first light applying condition. A second light source applies second light to reproduce the recorded image from the light-to-light converter and project the reproduced image onto a screen under a second light applying condition independent of the first light applying condition.
