  • Patent number: 9202284
    Abstract: An apparatus includes an extraction unit to extract a feature point in a first image. A determination unit determines a motion vector that corresponds to the 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 feature point and image data for the corresponding point, among candidates of the corresponding point in the second image. A correction unit corrects a first motion vector determined by the determination unit by employing a second motion vector determined by the determination unit. The correction unit employs the second motion vector, in accordance with both of a first degree of similarity between the feature point and the corresponding point, and a second degree of similarity between the feature point and another candidate among the candidates.
