Patent ID: 8090020

Claim:
A moving picture encoding device for dividing an original picture inputted for each frame into motion compensation blocks and encoding each of the motion compensation blocks using motion compensation inter-frame prediction, comprising: a moving picture encoding unit to divide the original picture into motion compensation blocks and to encode each motion compensation block, using inter-frame motion compensation frame prediction; a fade scene detection unit to specify a scene as the fade scene, when horizontal and vertical components of the motion vector are Vx and Vy, respectively, expression Σ| Vx |>first threshold, Σ| Vy |>second threshold [expression (1)] is held, and at least one of expressions |Σ Vx|/Σ|Vx| <third threshold, |Σ Vy|/Σ|Vy |<fourth threshold [expression (2)], total number of intra-motion compensation blocks/total number of motion compensation blocks >fifth threshold [expression (3)], and sixth threshold<Σsum of absolute differential values of motion compensation blocks<seventh threshold [expression (4)] are held; and an encoding control unit to control encoding by the moving picture encoding unit of the original picture constituting the fade scene, according to a detection result of the fade scene detection unit.
