Abstract
Virtually complete freedom from flicker is achieved by converting a line-interlaced 50/60 Hz video signal to a progressive 100/120 Hz video signal. For this purpose, the video signal on the input side is first converted to a 100/120 Hz signal with line-interlaced fields, and the progressive video signal is then produced from the first converted signal taken together with the non-converted input signal.
