摘要

A contour emphasizing circuit which has a first Y-signal generator (35) which generates a luminance signal from digital R, G, and B signals, line memories (31r, 31g and 31b) which delay the R, G and B signals by one line respectively, a second Y-signal generator (37) which generates a luminance signal from the outputs of the line memories, a contour extracting circuit (39) which extracts the vertical contour component and the horizontal contour component, a factor multiplier (42) which multiplies those contour components by factors Kr, Kg and Kb and outputs contour components for R, G and B and contour adders (34r, 34g and 34b) which add the contour components for R, G and B to the R, G and B signals respectively.
