A defect review apparatus for reviewing a specimen by moving the specimen to pre-calculated coordinate includes: a function to measure a deviation amount between the pre-calculated coordinates and coordinates of an actual position of the specimen; a function to optimize a coordinate correcting expression to minimize the measured deviation amount; and a function to determine that the deviation amounts have converged. When the deviation amounts have converged, the measurement for the coordinate-correcting-expression optimization is terminated, minimizing a reduction in throughput. field of view (FOV) necessary for the specimen to be within the FOV is set according to a convergence value of the calculated deviation amount.
