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). The controllable fraction (cx, cy) is generated by a non-linear function (HCF, VCF).
