A method for eliminating lens flare that eliminates lens flare is provided. The lens flare elimination method performs: a step for acquiring images by irradiating the coaxial episcopic illumination light with varying irradiation intensities and capturing images at each irradiation intensity while the object is not placed on the mounting table; a step for capturing an image of the object by irradiating the object placed on the mounting table with the coaxial episcopic illumination light at an arbitrary irradiation intensity; a step for estimating an image for correction, which is the image at the irradiation intensity irradiated when the measurement object is captured, based on the images acquired in the image acquiring step; and a step for generating a post-correction image in which the lens flare is eliminated from the image of the object by obtaining the difference between the image of the object and the image for correction.
