Abstract:
1. An apparatus comprising: an extraction unit configured to extract an edge feature point corresponding to an edge in a first image, from the first image; a first determination unit configured to determine temporally a temporal motion vector that corresponds to the edge feature point extracted from the first image by the extraction unit and a corresponding point that is located in a second image and that has a highest degree of similarity between image data for the edge feature point and image data for the corresponding point among candidates of the corresponding point in the second image; a setting unit configured to set a feature point, on a corner of the first image, regardless of whether the set feature point corresponds to an edge in the first image or not; a second determination unit configured to determine a motion vector corresponding to the edge feature point, by using a first temporal motion vector determined for the edge feature point by the first determination unit and a second temporal motion vector determined by the first determination unit, in accordance with the highest degree of similarity and to determine a motion vector corresponding to the set feature point set on the corner by the setting unit, using a temporal motion vector corresponding to a neighboring edge feature point and without using a temporal motion vector corresponding to the set feature point; and at least one processor configured to function as at least one of the extraction unit, the first determination unit, the setting unit, and the second determination unit.
