Abstract
A first condition determining portion 6 determines whether or not a picture moves corresponding to inter-field variations of space variation amounts SG (t), SG (t−1), and SG (t+1). A second condition determining portion 7 determines whether a picture moves corresponding to inter-field differences FiGu (t−1), FiGu (t), FiGd (t−1), and FiGd (t). A third condition determining portion 8 determines whether or not a picture moves corresponding to a ratio gf of the inter-frame difference FrG to the space variation amount SG (t). When one of the first to third conditions is satisfied, an OR gate 9 outputs data “1” that represents that a picture moves.
