Abstract
A charged particle beam device includes a plurality of detectors configured to detect one or more signal charged particle beams caused by irradiation on a sample with one or more primary charged particle beams, and a control system. The control system is configured to measure an intensity distribution of the one or more signal charged particle beams detected by the plurality of detectors, and correct the intensity distribution by using a correction function. The control system is configured to generate an image based on the corrected intensity distribution.
