  • Method and apparatus for detecting motion and absence of motion between odd and even video fields
    Patent number: 6647062
    Abstract: A method and apparatus are provided whereby the motion between two video fields of opposite parity may be measured so as to discriminate between the presence of motion and lack thereof. The level of motion at a specified position is determined by comparing a first motion value derived from successive fields of opposite parity with a second motion value derived from successive fields of the same parity at the spatial location corresponding to that used to generate the first motion value. This determination is made with one field being common to the first and second motion values, and taking the minimum of the first and second motion values to be the motion value at that position.
