Abstract
A moving image encoding apparatus includes an image encoder and a prediction structure determination unit. The image encoder having a first mode for performing intra-frame coding for moving image data without performing prediction along a time axis, the moving image data being constituted by a plurality of continuous frames, a second mode for performing inter-frame prediction for the moving image data using one-way prediction along the time axis, and a third mode for performing frame interpolation prediction for the moving image data using two-way prediction along the time axis. The prediction structure determination unit determines positions for one or more frames to be subjected to the intra-frame coding in the first mode, frames to be subjected to the inter-frame prediction in the second mode, and a frames to be subjected to the frame interpolation prediction in the third mode in accordance with at least the number of frames corresponding to inter-frame prediction coding in the second mode that occur in an input image signal.
