摘要： An illumination unit emits an illumination light to a specimen. An image sensor includes multiple pixels arranged in a two-dimensional manner. The image sensor captures an image of the intensity distribution of an interference pattern formed due to the illumination light that has interacted with the specimen, and outputs image data. A defect information acquisition unit acquires defect position information that indicates the positions of defective pixels of the image sensor. A processing unit reconstructs a subject image that represents the specimen based on the image data and the defect position information.
