摘要：A method and system for detecting the motion between a video field and itsprevious and subsequent video fields at a specified position. The motion detection
scheme and system allows signal values of one set of vertically adjacent pixels from avideo field of one parity and two other sets of vertically adjacent pixels from twoneighboring video field of opposite parity to be measured such that when takentogether, these pixels represent relevant sample of an image near the vertically andtemporal position of the video field. The motion detection scheme also allows thecalculation of three motion values between the video field and its previous video field,the video field and its subsequent video field and the previous and subsequent fields ofthe same video field. The overall level of motion at the field being measured is
determined by combining the information from the three motion values calculated at thespecified spatial and temporal location.
