Abstract
Black field failure and static frame failure are two kinds of abnormal states in the process of radio and television broadcast. To explore an effective method to eliminate the two faults, so as to ensure the safety of radio and television broadcasting, has a very important practical significance. This paper introduces a method to detect black field failure and static frame failure which based on digital image processing techniques. During the detection,the image block processing is introduced, and the gray values of the inner frame images and the adjacent frame images need to be calculated and contrasted. The Matlab simulation analysis was carried on has proved its feasibility at last.
