A method which is used for optically detecting moving objects method comprises an image recording unit 1, a computing unit 2 with a memory 4, and a signal display 5. The computing unit compares an image recorded by the image recording unit with a reference image in relation to the measured variables: image signal variation, displacement and texture. For determining the comparison values the chronological mean value and the chronological variance are thus preferably used for describing the typical distribution of the measured variables in each case. If the comparison displays an atypical image signal variation and an atypical texture and an atypical displacement, a moving object is detected, a signal is emitted, and the actual image signal is stored as the new reference image signal and is used as the reference image signal for the next comparison. <IMAGE> |
