International ClassH04N 009/74Foreign Application Priority Data1994-04-28 JPAbstractA special effect picture device is disclosed in which a transformed picture which is non-linear with respect to an original signal is formed using a video signal and a key signal for the original signal. A video signal is stored in a video signal storage unit and a key signal is stored in a key signal storage unit. The read-out addresses for the information concerning an upper picture of the transformed picture and the information concerning a lower picture of the transformed picture and also the information concerning the depth are generated by a read-out address generating unit. The key signal read out from the key signal storage unit and the video signal read out from the video signal storage unit are respectively divided by a dividing unit into upper and lower key signals and upper and lower video signals responsive to the read-out address for the upper picture and read-out address for the lower picture. The upper picture and the lower picture are synthesized by a picture synthesizing unit using the upper and lower key signals and the upper and lower key signals divided by the dividing unit. The synthesized picture synthesized by the picture synthesizing unit is freed of unnecessary portions depending on the depth information generated by the read-out address generating unit for generating the transformed picture. | |
