Abstract
NOVELTY - The method includes the steps of detecting an actual pixel value, and determining subsequently the difference between the detected pixel signals and a reference value. Dependent on the difference, it is determined whether a change of the detected pixel value in comparison with the preceding pixel values is provided, whereby the reference signal is generated from two or more of the detected pixel values with regard to the preceding detected pixel values. USE - Especially for detection of moving object in image sequence. ADVANTAGE - Enables reliable detection of even small movement, and prevents occurrence of image artifacts.
