    • PROBLEM TO BE SOLVED: To acquire an image suitable for flaw detection.
      SOLUTION: An imaging method includes the steps of irradiating an objective region to be inspected with illuminating light, acquiring a reference image of the objective region to be inspected in accordance with reference imaging conditions of reference standards, dividing the reference image to a plurality of clusters by clustering, determining whether each cluster matches predetermined conditions, changing the imaging conditions of a cluster that does not match predetermined conditions when each cluster does not match predetermined conditions, acquiring the image of a cluster that does not match predetermined conditions in accordance with the imaging conditions changed, repeating the changes of imaging conditions and the acquisition of the images of clusters until all clusters match predetermined conditions, and synthesizing each cluster matching predetermined conditions to acquire a synthesized image on the objective region to be inspected when it is determined that all clusters match the predetermined conditions.
