Document Type and Number:
Japanese Patent JP4421940
Kind Code:
B2
Abstract:
A moving picture encoding apparatus for encoding a stereoscopic moving picture in which right-eye pictures and left-eye pictures are arranged alternately in every other column and an interlaced moving picture in which pictures of odd number row and pictures of even number row are arranged alternately in every other row according to one embodiment comprises: a moving picture type judgment section for judging whether the moving picture to be encoded is a stereoscopic moving picture based on the input picture signal representing the moving picture to be encoded; a motion detection section for selecting a prediction mode in accordance with the type of the moving picture obtained by the judgment, and for, when an interframe prediction mode is selected as the prediction mode, detecting a motion vector for the moving picture to be encoded; a motion compensation section for performing motion compensation for the moving picture based on the type of the moving picture, the selected prediction mode, and the detected motion vector; a spatial prediction section for performing a spatial prediction for the moving picture based on the type of the moving picture and the selected prediction mode; an orthogonal transformation section for performing an orthogonal transformation for a predictive residue signal obtained as a difference between the predicted picture signal obtained by the motion compensation or the spatial prediction and the input picture signal, based on the type of the moving picture and the selected prediction mode; and a variable length encoding section for performing predetermined picture processing including variable length encoding for the picture data after the orthogonal transformation, based on the type of the moving picture and the selected prediction mode.
