Claim 9:
10. An operation method for a charged particle beam device, the charged particle beam device including a GUI configured to display an image and receive an input from a user, the operation method comprising:
setting a parameter for an optical system configured to irradiate a sample with a plurality of primary charged particle beams;
individually detecting a plurality of secondary charged particle beams emitted from the sample;
converting a detected signal into a digital pixel and storing the digital pixel as an image;
deriving an evaluation value of the primary charged particle beam from the image; and
reducing a plurality of the detected images and simultaneously displaying, on a screen of the GUI, the reduced images and evaluation results based on the evaluation values adjacently.
