Abstract
In order to solve the problem that the resolution of a back-scattered electron image without a contrast difference between materials with close atomic numbers is low, an image processing apparatus that performs an image process on a back-scattered electron image as an input image includes: a material peak detection unit that determines a peak luminance value with a peak of a frequency of a luminance histogram based on a luminance value obtained for each measurement position by using the input image as an input and information about material-dependent back-scattered electron generation efficiency, and that outputs the peak luminance value for each material; and an image information adjustment unit that emphasizes a material-dependent contrast on the basis of the input image and the peak luminance value for each material.
