摘要： An image matching apparatus for obtaining a correspondence relationship between a source image and a destination image, includes an potential force calculator that calculates potential energy based on a correlating relationship of images between each first lattice point on the source image and each second lattice point corresponding one-to-one to the first lattice point on the destination image, and calculates potential force that the second lattice points receives by gradient of the potential energy based on a position of each second lattice point and a position of each first lattice point corresponding to the second lattice point. The potential force calculator sets the potential force calculated last time to the potential force of this time with respect to the second lattice points determined not to execute the calculation process of the potential force.

摘要： A method of generating an interpolation image includes inputting a first reference image, a second reference image and a third reference image of a video signal that continue in terms of time, generating a first interpolation image corresponding to a position of the second reference image from the first reference image and the third reference image, computing a correlation value expressing a correlation level between the second reference image and the first interpolation image, generating a second interpolation image corresponding to an interpolation position between the second reference image and the third reference image, and interposing the second interpolation image in the interpolation position when the correlation value is more than a threshold.

摘要： A first motion vector is estimated by using a first frame and a second frame that follows the first frame. A support frame is generated from at least either the first or the second frame by using the first motion vector. The support frame is divided into a plurality of small blocks. Motion vector candidates are estimated by using the first and second frames, in relation to each of the small blocks. A small block on the first frame, a small block on the second frame and the small blocks on the support frame are examined. The small block on the first frame and the small block on the second frame correspond to each of the motion vector candidates. A second motion vector is selected from the motion vector candidates, and points the small block on the first frame and the small block on the second frame which have the highest correlation with each of the small blocks on the support frame. An interpolated frame is generated from at least either the first or the second frame by using the second motion vector.
