There is provided an image-reconstruction system capable of implementing a multi-axes reconstruction technique for lessening a burden on the part of a user, and precluding artifacts high in contrast, contamination of a sample, and restrictions imposed on a sample for use, occurring due to use of markings.A plurality of tilt-images photographed by tilting a sample at sample-tilt axes, differing from each other; are acquired, misregistration is corrected by a rotation step-angle, a rotated object under observation is tilted in angle-steps, differing from each other, to pick up images thereof, two reconstruction images obtained by correcting respective misregistrations of two reconstruction images created from respective tilt-image groups are created, and one reconstruction image is created by superimposing one of the two reconstruction images on the other.
