Abstract: A probe driving method and a probe apparatus for bringing a probe into contact with the surface of a sample in a safe and efficient manner by monitoring the probe height. Information about the height of the probe from the sample surface is obtained by detecting a probe shadow (54) appearing immediately before the probe contacts the sample, or based on a change in relative positions of a probe image and a sample image that are formed as an ion beam is irradiated diagonally.

Abstract: PROBLEM TO BE SOLVED: To provide an image evaluation method to objectively evaluate image resolution of a microscope image. SOLUTION: The image evaluation method is characterized in that resolution in partial regions of an image is obtained over an entire area of the image or a portion of the image and averaged over the entire area of the image or the portion of the image, and that average is to be a resolution evaluation value of the entire area of the image or the portion of the image. With this structure, this method eliminates subjective impressions of an evaluator in evaluation of microscope image resolution, so that image resolution evaluation values of high accuracy and good repeatability can be obtained.
