ABSTRACT:
Dot matrix characters are rounded by interpolating quarter dots in the angles of diagonal strokes with the feature that the video signal is a line interlaced signal; the diagonals are detected as predetermined logical combinations of an undelayed signal, a dot-delayed signal, a line delayed signal and a line-plus-dot delayed signal; the quarter dots are interpolated in real time as the diagonals are detected but are interpolated in a first one of the said signals in first fields and in a second one of the said signals in the second, interlaced fields, the second signal being line-delayed relative to the first signal.
