Title: Line- and edge-flicker reducing circuit for TV signal - interpolates delayed luminance signal, and logically combines under control of edge or movement detector before compressing
Inventor: HENTSCHEL CHRISTIAN DR
IPC: H04N5/44
Filed: 1991-01-17
Abstract: The circuit includes a delay device (7) for delaying the acutal luminance signal by the period of a picture field. A vertical interpolation is performed (5) between consecutive lines of each field of the luminance signal to form an interpolated luminance signal. The delayed and interpolated signals are logically combined (12) and a detector (16) senses edges and/or movement in the television pictures and controls the logical combiner accordingly. A line compressor receives the actual luminance signal and the combined luminance signal and performs line-by-line compressions during half a line period, and outputs alternatively compressed luminance signals. ADVANTAGE - Reduced field memory requirement.
