Abstract
A method of acquiring an image of an image acquiring region of a sample comprises a first step of irradiating and scanning an ion beam in a first scan pattern on a first scan region of a sample, the scan region including therein the image acquiring region, and a second step of detecting secondary charged particles generated by irradiating and scanning the ion beam on the first scan region of the sample and generating first image data of the image acquiring region. The first and second steps are repeated a plurality of times using different scan patterns on different scan regions that differ from the first scan and the first scan region and from one another, each of the different scan regions including therein the image acquiring region, to generate a plurality of image data of the image acquiring region. Image data of the image acquiring region are generated by synthesizing all the image data generated by scanning the different scan region, and the synthesized image data of the image acquiring region are displayed on a display unit.
