Improvement of one-dimensional reproduced images including frequency components higher than Nyquist frequency was discussed. Noises existing on the reproduced image are caused by the positional defference between two input images. To reduce noises, precision of relative position between two images was increased by development of the new equipment and image spatial shifting program by Fourier transform was developed. As a result, quality of the reproduced image was improved, and the frequency components, which were 1.5 times as high as Nyquist frequency were successfully reproduced.
