Abstract:
A picture converting apparatus for converting an input picture signal into an output picture signal, the pixel positon of a first field of the input picture signal being different from the pixel position of a second field thereof, the first field being adjacent to the second field, the field frequency of the output signal being N times higher than the field frequency of the input picture signal, where N is an integer that is 2 or larger, comprising:a class deciding portion for designating each of all fields of the output picture signal that are not present in at least the input picture signal to a considered field and deciding a class for each considered pixel of each considered field according to a plurality of pixels of the input picture signal, the plurality of pixels being decided according to each considered pixel of the considered field; a memory portion for storing pre-obtained predictive information; a predictive pixel selecting portion for selecting a plurality of pixels of the input picture signal for each considered pixel; and a pixel generating portion for generating each considered pixel of the output picture signal according to predictive information for a class decided by said class deciding portion and a plurality of pixels selected by said predictive pixel selecting portion, wherein the pixel position of the output picture signal varies at intervals of fields equal to N, and wherein the pixel position of each field matches the pixel position of the first field or the second field of the input picture signal.
