1. A motion vector detecting apparatus for detecting a motion vector of an inputted image signal, comprising:

  • a motion vector arithmetic unit for calculating the motion vector of the inputted image signal;

    an integrator for integrating the motion vector;

    a still decision unit for judging whether or not the inputted image signal represents a still image;

    a coring value determiner for determining a coring value on the basis of outputs from said integrator and said still decision unit; and

    a coring circuit which controls the coring value on the basis of an output from said coring value determiner so as to perform coring processing on an output of said motion vector arithmetic unit.
