Motion detecting apparatus for detecting motion information of picture within signal

Image Number 5 for United States Patent #6693676.

A motion detecting apparatus for detecting the motion of the picture without error and realizing the motion YC separation or the motion adaptive scan-line interpolation with high accuracy is realized by correcting the motion amount of the pixel which is too much or too small in comparison with the peripheral pixels for the signal obtained by subtracting the output of the vertical edge detecting circuit for detecting the slow motion of the picture signal in the vertical direction from the combined outputs from the first detecting circuit for detecting motion information of the luminance signal low-pass component and from the second detecting circuit for detecting motion information of the color signal in the picture signal, and then adding the output of the horizontal edge detecting circuit for detecting the slow motion of the picture signal in the horizontal direction.
