Definition of defected point (bright spot, dark spot): It is identified as a defected point if its areaexceeds 1/2 of a single picture element (R, G, B).2. Definition of bright spot: It is identified as a bright spot if it is bright in the state of dark field and itsbright size remains unchanged3. Definition of dark spot: It is identified as a dark spot if it is dark in the state of white field and itsdark size remains unchanged4. Definition of two neighboring points: Defects of a group of picture elements (RB, RG, GB).
