Relative importance of spatial image characteristics in reproduction of alphanumeric characters was examined and significant anisotropy was found; at low distortion levels, horizontal image degradation is less objectionable than vertical but at higher levels vertical distortion is less objectionable; central portions of characters are found less important for legibility; upper portions carry more legibility information than lower portions; implications of these findings on image transmission systems are discussed.
