Method and device for detecting a change between pixel signals which chronologically follow one another |
摘要 |
For detecting a change between pixel signals which chronologically follow one another, a current pixel value is first deteced and, subsequently, the difference between the detected pixel signal and a reference value is determined. Depending on the difference, it is determined whether there is a change of the detected pixel value in comparison with the preceding pixel values, the reference signal being produced from two or more pixel values preceding the detected pixel value.
