<p>A weighting factor mode determination unit (13) determines whether to code an interlaced picture in a field mode or a frame mode, based on a value of a flag "AFF" indicating whether or not to switch between the field mode and the frame mode on a block-by-block basis and notifies switches (14 and 15) and a multiplexing unit (106) of the determined mode. The switches (14 and 15) select either the field mode or the frame mode according to the notified mode. A field weighting factor coding unit (11) or a frame weighting factor coding unit (12) performs respectively the coding of respective weighting factors when the respective modes are selected.</p> |
