<p>In a method of sharpness enhancement, an input signal (s) is filtered (HLHP, VLHP) to obtain a filtered signal (zx, zy), the filtered signal is multiplied (M2, M3) by a controllable fraction (cx, cy) to obtain multiplied signals, and the multiplied signals are added (A2) to the input signal (s). According to the invention, the controllable fraction (cx, cy) is generated by a non-linear function (HCF, VCF).</p> |
