Claim 4:
5. A charged particle beam apparatus comprising:
an imaging device that irradiates a sample with a charged particle beam and forms an image from information of the sample; and
a computer that is provided with a memory for storing each of images obtained by scanning same area multiple times by using the imaging device and a processor for executing image processing,
wherein the computer classifies each of images obtained by scanning the same area multiple times into images having deterioration and images having no deterioration,
performs image integration on the images having no deterioration, and
outputs an image obtained by the image integration, and
wherein the computer
evaluates an image quality by comparing an integrated image generated by selecting all of the images obtained by scanning the same area multiple times and performing image integration without depending on an operation of the user and each integrated image generated by performing image integration according to each pattern in which each image is selected or non-selected, and
outputs the integrated image selected from the plurality of integrated images based on the evaluation.
