1. A method of detecting motion direction and motion amount of a digital video signal in order to process a pseudo-moving image, comprising the steps of:

  • detecting an edge of said pseudo-moving image within a current frame and a previous frame and outputting an edge detected image, said detecting step including the steps of;

    calculating a gradient between adjacent pixels for each direction by a pixel unit of said video signal, and comparing a maximum gradient value with a given threshold value;

    converting the edge detected image into a binary-coded image;

    detecting an interframe motion vector with respect to only an edge part of the binary-coded image; and

    processing said pseudo-moving image as interframe motion or to a moving region based on said interframe motion vector.
