ABSTRACT:
A laser scanning and printing apparatus operates to scan an original picture in generally low resolution to provide a minimal quantity of image data which may be modified to provide an enhanced image reproduction of the original by subsequently laser scanning the original and directing the laser light reflected from the original to expose a photosensitive material, the intensity of the laser light being modulated to effect the enhanced image reproduction by selectively lightening or darkening predetermined areas of the photosensitive material exposed by the laser light reflected from the original picture during the subsequent line scan thereof.
