摘要

It is the defective pixel tester which judges the defective pixel of the digital video camera. This tester has with the video input section and memory and the controller. The video input section receives the video frame from the digital video camera. Each video frame is demarcated by plural pixel values. Memory remembers the video frame and the pixel test result which kiyapuchiya are done. The controller forms the finite difference value of the pixel value which corresponds from the video frame which differs, forms the pixel test result on the basis of the comparison with the finite difference value and threshold, remembers the pixel test result in memory.
