Abstract

Color terminals Often use a repeat field technique for the display of binary image information. The initial approach to producing color hard copy is to repeat each scan line twice. This results in an image compatible with the interlaced repeat field. The image, however, may appear jaggered. An improved image with reduced jaggedness is obtained when the image expansion is done by interpolation rather than replication.
