Motion vector detecting method of a video signal
First Claim
Patent Images
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.

Abstract
A motion vector detecting method of a digital video signal includes an edge image detecting process for detecting an edge for the video signal within a current frame and a previous frame, an image converting process for converting the edge detected image from the edge image detecting process into a binary-coded image, and a motion vector detecting process for detecting an interframe motion vector with respect to only an edge part from the binary-coded image.
