Abstract
A method for determining which of pairs of successive video fields have interlace scan characteristics includes generating accumulated differences FD of pixels in successive lines of respective fields of successive pairs of fields and generating accumulated differences FR of pixels in successive lines of interlaced said pairs of fields. The accumulated differences FD and FR are compared and pairs of said fields are classified as interlaced if the ratio of accumulated differences FR/FD is greater than a predetermined threshold value.
