1. A computer implemented method stored on a recordable media for performing digital color transition improvement (DCTI) on a N-pixel delayed signal of a digital chrominance signal, said method comprising.using said digital chrominance signal, said N-pixel delayed signal and a 2N-pixel delayed signal of said digital chrominance signal, generating a first and second difference signals of first order;

  • using said first and second difference signals of first order, generating a difference signal of second order; and

    generating a first weighted sum of the digital chrominance signal, the 2N-pixel delayed signal and a first weight factor determined by applying a first set of fuzzy logic inference rules to the first difference signal of first order and the difference signal of second order.
