One-dimensional reproduced images have been improved to include frequency components higher than the Nyquist frequency. To reduce the noise in reproduced images, which is caused by the positional shift between two input images, the precision of the relative position between the images was increased by developing new equipment and an image spatial shifting program by using a Fourier transform. The quality of reproduced image was there by improved, and frequency components 1.5 times as high as the Nyquist frequency were reproduced.
