The circuit for preventing the contour of the vertical still screen from being dull comprises a line storing unit (LM) for delaying an inputted luminance signal (Y) for one line, a luminance signal mixing unit (100) for mixing the luminance signal (Y') output of the unit (LM) with the inputted luminance signal (Y) according to a coefficient control signal (M), a field storing unit (FM) for storing the inputted luminance signal (Y) for one field, a difference coefficient generating unit (200) for outputting a luminance difference as coefficient control signal (M), a mixer (MIX) for mixing an operating coefficient control signal (K) with the signal (M) and an interpolation signal output unit (300). |
