| Zusammenfassung: | To shorten a time required for evaluation of a recipe while suppressing an increase in a data amount. A charged particle beam device includes a microscope that scans a charged particle beam on a sample, detects secondary particles emitted from the sample, and outputs a detection signal and a computer system that generates a frame image based on the detection signal and processes an image based on the frame images. The computer system calculates a moment image between a plurality of the frame images, and calculates a feature amount data of the frame image based on a moment. |
