A moving video image estimation system is provided, in which, when a video image occurring at an arbitrary time t between time n and time n + 1 or at an arbitrary time t after time n + 1 is produced for time series video images given at discrete times 1, 2, ... n, n + 1, ..., even if the position and shape of an object in the video image are considerably changed between the frames, the video image of the object in the original frame can be prevented from being reproduced doubly in the interpolated video image. Based on an original video image of time n and time n + 1, the centroid, the principal axis of inertia, the moment about the principal axis of inertia and the moment about the axis perpendicular to the principal axis of inertia are obtained. By using them, an affine transformation for transforming the original video image at time n to the original video image at time n + 1. Further, based on the infinitesimal transformation (A), ?exp (At), and exp(A (t - 1))} obtained by making the affine transformation continuous with regard to time is executed on the original video image at time n and time n + 1. The results are synthesized to perform an interpolation between the frames. {exp (A (t - 1))} is applied to the original video image at time n + 1, the video image after time n + 1 is predicted.
