摘要

For each of a plural number of pixels in a reference frame, a corresponding point estimation unit (2) estimates a corresponding point in each of a plural number of picture frames differing in time. A first gray scale value generation unit (3) finds the gray scale value of each pixel from the gray scale values of the neighboring pixels for each corresponding point in each picture frame estimated. A second gray scale value generation unit (4) approximates the gray level of a locus of corresponding points, by a fluency function, from the gray scale values of the corresponding points at each picture frame estimated to find each gray scale value of the corresponding point in the picture frame for interpolation from the above function. From the gray scale value of each corresponding point in the frame for interpolation, a third gray scale value generation unit (5) generates a gray scale value of each pixel in the picture frame for interpolation.
