The high magnification, high resolution and real-time property of an SEM image are realized when the electrical characteristics of an inspection object are measured, without affecting the electrical characteristics of the inspection object. A high-quality, high-magnification first image including an image of a target position in the inspection object on a sample is acquired. Next, a low-quality, low-magnification second image including the image of the target position in the inspection object on the sample and probe images is acquired. Next, data on the first image is built into the second image to generate an image for coarse-access observation which is the same in magnification as the second image. The generation of the image for coarse-access observation is repeated until a probe comes close to the target position in the inspection object.
