Abstract
Contour extraction circuits extract contour components YE, CbE, and CrE, respectively, from luminance signal Y, and color-difference signals Cb and Cr, respectively. The two contour components CbE and CrE of the color difference signals are inputted to the LUTs respectively, via the selectors respectively, and converted into the adjustment signals Kand K, respectively. The multiplier multiplies the contour component YE by the adjustment signal Kso as to generate the modulated contour component E. The multiplier multiplies the modulated contour component Eby the adjustment signal Kso as to generate the modulated contour component E. The adder adds the modulated contour component Eto the luminance signal Y so as to generate the luminance signal Ya, which has been contour-enhanced based on the contour component of the luminance signal and the contour components of the color-difference signals.
