Claim Text:
1. A method for capturing an image of a sample using a charged particle microscope device, the method comprising: a target signal amount calculation step of calculating a target signal amount; an image capturing step of scanning the sample with a charged particle beam and capturing a first image of the sample; an image-capturing continuation determination step of comparing a signal amount in a region comprising a pixel of a relatively small signal amount in the first captured image and the calculated target signal amount, and determining whether or not to continue to capture an image; and an image-capturing continuation step of, when it is determined, in the image-capturing continuation determination step, to continue to capture an image, calculating a region of the sample to be scanned again, based on a position of a pixel of a relatively small signal amount in the first captured image, scanning the calculated region of the sample to be scanned again with a charged particle beam and capturing a second image, and combining the first image and the second image, wherein the image-capturing continuation determination step and the image-capturing continuation step are repeated until it is determined, in the image-capturing continuation determination step, not to continue to capture an image.
