Abstract
A frame interpolation device and method are provided. The device includes an in-screen average motion vector calculation section, a scene detection control section, a correlation calculation section, a no-motion determination section, a search center weight assigning section, a vector center weight assigning section and a weight assigning selection processing section. The in-screen average motion vector calculation section calculates an in-screen average motion vector in a screen for each the video frame. The scene detection control section detects any scene showing a uniform motion in each video frame. The correlation calculation section calculates, for each motion vector candidates for each block in target video frame, a correlation value between the target video frame and other previous video frames. The weight assigning selection processing section selects the search center weight assigning section or the vector center weight assigning section, and provides thereto the correlation value. An output from selected section is output.
