ABSTRACT:
Ragged vertical edges normally displayed by a NTSC color-carrier on a non-interlaced display are effectively eliminated through persistence of vision by altering the duration of a selected single scan-line of the non-display portion of each of successive fields by an odd number of half-cycles of the NTSC color-carrier frequency.
