摘要： PROBLEM TO BE SOLVED: To provide a motion picture encoding device capable of reducing processing delay in motion compensated time direction band division and encoding motion pictures with high encoding efficiency. SOLUTION: In the motion picture encoding device, a plurality of pictures in a motion picture are to be encoded in pairs. The image to be encoded is band-divided into a high band signal and a low band signal by band division processing. The high band signal is made into a compressed high band signal by first encoding processing, and the low band signal is made into a compressed low band signal by second encoding processing. The compressed low band signal is made into a reproduced low band signal by second decoding processing. In the second encoding processing, the prediction signal of the low band signal to be encoded is generated from a reproduced low band signal based on another low band signal, and a residual signal is encoded based on the difference between the low band signal to be encoded and the above reproduced low band signal.

摘要： PROBLEM TO BE SOLVED: To solve the problem that in an encoding method using an in-screen prediction signal generation method in a pixel area, the same conversion encoding method is applied to a difference signal between a pixel signal of an object region and a prediction signal irrespective of the in-screen prediction signal generation method and consequently an amount of codes of the difference signal can not be effectively reduced even if a prediction accuracy is raised. SOLUTION: A prediction signal generation means generates a plurality of texture signals by different prediction signal generation methods with reference to already reproduced pixels and selects, as a prediction signal of an object region, a texture signal having highest correlation with an object pixel signal among the plurality of texture signals. An encoding means encodes mode information that instructs the predictive signal generation method of generating a selected texture signal. A scanning means generates one dimensional data of conversion coefficients or quantization conversion coefficients using a scanning method corresponding to the prediction signal generation method. A reverse scanning means generates a conversion coefficient matrix of a reproduced residual signal or a quantized conversion coefficient matrix by reversely scanning the one dimensional data using a reverse scanning method corresponding to the mode information.
