Patent ID: 8559517

Claim:
A picture signal processing apparatus comprising: a motion vector detecting unit for detecting a first motion vector information pixel by pixel from a plurality of frames contained in an input picture signal; an interpolation frame producing unit for producing an interpolation frame, which is configured to execute a plurality of interpolation frame producing processes including a first interpolation frame producing process based on the first motion vector information, and a second interpolation frame producing process based on a second motion vector information which is calculated from a histogram of the first motion vector information for a plurality of pixels in a frame; and a frame stream producing unit for producing a picture signal of a new frame stream including an interpolation frame produced by the first interpolation frame producing process, an interpolation frame produced by the second interpolation frame producing process, and the frames of said input picture signal; wherein: said frame stream producing unit keeps two or more interpolation frames produced by said first interpolation frame producing process not continued in a temporal manner in said new frame stream producing process; wherein: said interpolation frame producing unit changes said interpolation frame producing process based on whether the format of said input picture signal is a non-pull down format or a 2-to-3 pull down format.
