Abstract:
A method for measuring motion at a horizontal and vertical position between video fields of opposite parity comprising the steps of:receiving pixels from a first video field of one parity, a second field of the opposite parity and a third field of said one parity; measuring the signal value of at least one pixel from said first video field and at least one pixel from said second video field; measuring the signal value of at least one additional pixel from said third video field, wherein said additional pixel is at an identical horizontal and vertical position to said at least one pixel from said first video field; comparing the signal values of said at least one pixel from said first video field and said at least one pixel from said second video field and generating a measure of the motion between said first and second video fields; comparing the signal values of said at least one pixel from said first video field and said at least one additional pixel from said third video field and generating a measure of the motion between the first and third video fields; and outputting a motion value equal to the lesser of said measure of the motion between the first and second video fields, and said measure of the motion between the first and third video fields.
