Patent Number: 
Section: claims

1. An image processing device for making a comparison between an optical microscope image acquired by an optical microscope, and an elemental mapping image acquired by a charged-particle beam device, comprising:a comparing unit for making said comparison between said optical microscope image of a specimen stained for an observation made by said optical microscope and said elemental mapping image, said optical microscope image being acquired by said optical microscope, said elemental mapping image being based on detection of X-rays by said charged-particle beam device, andan outputting unit which outputs, as a location or locations that a charged-particle beam image is acquired by said charged-particle beam device, position information of a location or locations in the specimen such that coincidence degrees between said optical microscope image and said elemental mapping image exceeds a predetermined value specified by a user, or obtain a highest value. 2. The image processing device according to claim 1, whereinsaid locations on said specimen are ranked in a descending order of said coincidence degrees. 3. The image processing device according to claim 1, whereinsaid optical microscope image or said elemental mapping image, and the position information outputted by the outputting unit or a charged-particle beam image at the location or locations corresponding to said position information are recorded as a single file. 4. An image processing device for making a comparison between an optical microscope image acquired by an optical microscope, and an elemental mapping image acquired by a charged-particle beam device, comprising:a comparing unit for making said comparison between said optical microscope image of a specimen for an observation made by said optical microscope and said elemental mapping image, said optical microscope image being acquired by said optical microscope, said elemental mapping image being based on detection of X-rays by said charged-particle beam device, anda storing unit for storing a secondary-electron image or reflection-electron image of a location or locations in the specimen such that coincidence degrees between said optical microscope image and said elemental mapping image exceed a predetermined value specified by a user, or obtain a highest value. 5. The image processing device according to claim 4, whereinsaid locations on said specimen are ranked in a descending order of said coincidence degrees. 6. The image processing device according to claim 4, whereinsaid optical microscope image or said elemental mapping image, and the position information outputted by the outputting unit or a charged-particle beam image at the location or locations corresponding to said position information are recorded as a single file.
