Abstract:
A defect discriminating method which discriminates a defective element of a solid-state detector in which a number of detecting elements to detect visible light or radiation are arranged,forming at least one of: a first histogram based on first detection signals outputted from said detecting elements in a dark state and a second histogram based on second detection signals outputted from said detecting elements in a bright state, determining a representative value of said at least one of said first detection signals and said second detection signals, determining a value of said at least one of said first detection signals and said second detection signals which corresponds to a specified frequency of said at least one of said first histogram and second histogram and is the closest to said representative value as a defect discrimination value, and detecting elements among said detecting elements which outputs a detection signal beyond said defect discrimination value as a defective element.
