Claim 0:
1. A charged particle beam device, comprising:
an optical system configured to irradiate a sample with a plurality of primary charged particle beams;
an optical parameter setting unit configured to set a parameter of the optical system;
a detector configured to individually detect a plurality of secondary charged particle beams emitted from the sample;
a plurality of storage units each configured to store a signal, that is detected by the detector and converted into a digital pixel, in a form of a detected image;
an evaluation value derivation unit configured to derive an evaluation value of the primary charged particle beam from the detected image; and
a GUI configured to display an image and receive an input from a user;
an image reduction unit configured to reduce the detected image;
a display image memory configured to store the image reduced by the image reduction unit; and
a display control unit configured to simultaneously display, on a screen of the GUI, a plurality of reduced images stored in the display image memory and evaluation results based on the evaluation values adjacently.
