Abstract
An image capturing unit captures an image of a surface of a member treated by a surface treatment unit. A comparison unit obtains a correlation coefficient between a reference image stored in a storage unit and the image captured by the image capturing unit. A cross-correlation coefficient between power spectra of the reference image and the image captured by the image capturing unit is obtained. A control unit stops a surface treatment performed by the surface treatment unit when the correlation coefficient obtained by the comparison unit reaches a set value.
