A possible system for obtaining television type images of normal typewritten characters is described in this paper. It is intended to use this system for the extraction of postal codes from envelopes. A flying spot scanner is controlled by a data processor in two phases. In the first the postal code is found and the height is estimated, and in the second the images of the separate characters are obtained. Corrections to the width, height, and position are made by altering the scan raster.
