摘要： A picture signal processing unit having a first and a second double rate conversion section, a storage section, and a quadruple rate conversion section is provided. The first double rate conversion section inserts a first interpolation frame between a couple of successive original frames to output the original frames and the first interpolation frames. The second double rate conversion section generates a second and a third interpolation frames and allocates the second and the third interpolation frames between the couple of successive original frames to output the second and the third interpolation frames. The storage section stores the original frame and the first to the third interpolation frames. The quadruple rate conversion section sequentially reads out the original frame and the first to the third interpolation frames from the storage section in a quadruple rate to output the original frame and the first to the third interpolation frames.
