DEVICE FOR DETECTING CANDIDATE OF ABNORMAL SHADOW

摘要

PROBLEM TO BE SOLVED: To always keep a prescribed detection level even when detecting an abnormal shadow candidate in an image on the basis of image data which are standardized under different standardization conditions and have different concentrations and contrast. SOLUTION: A re-standardization processing means 10 inputs standardized image data P' to which standardizing processing is applied on the basis of an arbitrary standardizing condition, and obtains re-standardized image data P" having a prescribed concentration and contrast on the basis of the data P'. An abnormal shadow candidate detecting means 20 inputs the data P" from the means 10, and detects an abnormal shadow candidate in the image on the basis of the data P".
