The image sensor system includes an image sensing means for producing an image signal by sensing a field of view. This image signal is sent to a means which reproduces an image of the field. An optical projection means forms an optical image of this image of the field reproduced by the image reproducing means, at the same size as and in registration with the field itself and illuminating the field. Thereby contrast of the image of the field is improved by an optical feedback process.
