Abstract
This invention relates to a method of boosting a discontinuous-value video signal (in pulse or stepped form). From the video signal there is derived an upper accompanying signal extending above it and a lower accompanying signal extending below it, which follow the video signal dynamically. First differential values are formed between the upper accompanying signal and the video signal and second differential values are formed between the video signal and the lower accompanying signal. To boost the discontinuous-value video signal, multiples of the first differential values are subtracted continuously from the video signal and multiples of the second differential values are added to the video signal.
