PROBLEM TO BE SOLVED: To reduce folding distortion and to restore the high frequency component of an original signal by negating a folding component on plural two-dimensional digital data having the changes of sampling positions, which are not necessarily be the parallel shift of rotation and zoom. SOLUTION: N-pairs of two-dimensional data which are sampled by dislocating the same object are inputted 1, and respective input data are divided into plural blocks. A position difference estimation part 4 obtains the sampling positions of the respective blocks. A weighting calculation part 5 obtains weight corresponding to the sampling position difference. Wide band LPF and a high resolution part 7 LPF-process input data, make it into high resolution and a product-sum part 9 multiplies data of an intermediate buffer 8 by weight and adds them. |
