ABSTRACT:
The present invention relates to a movement vector detection apparatus for obtaining the movement amount of an image from the density difference between frames and the spatial inclination. More particularly, the present invention relates to a movement vector detection apparatus having a first operation circuit for operating the movement vector in accordance with an estimation equation approximating an influence of the diagonal spatial inclination component, a second operation circuit for obtaining a signal denoting the amount of the diagonal spatial inclination component of a supplied image signal and a third operation circuit for averaging the output from the first operation circuit under a weight which corresponds to the output from the second operation circuit.
