Abstract

A method, an apparatus, and a program for more appropriately determining a condition for appropriately recognizing a semiconductor pattern are provided. A method for determining a condition related to a captured image of a charged particle beam apparatus including: acquiring, by a processor, a plurality of captured images, each of the captured images being an image generated by irradiating a pattern formed on a wafer with a charged particle beam, and detecting electrons emitted from the pattern, each of the captured images being an image captured according to one or more imaging conditions, the method further including: acquiring teaching information for each of the captured images; acquiring, by the processor, one or more feature determination conditions; calculating, by the processor, a feature for each of the captured images based on each of the feature determination conditions, at least one of the imaging condition and the feature determination condition being plural.
