Abstract
An image processing system including an image coding apparatus and an image decoding apparatus. The image coding apparatus includes an image input unit for acquiring key frames, a matching processor for generating correspondence information between the key frames, a sound input unit for acquiring sound data to be synchronized with the key frames and correspondence information, and a stream generator for generating a coded data stream which includes the sound data, the correspondence information, and the key frames. The image decoding apparatus includes a stream input unit for acquiring the added data stream, a stream separator for separating the key frames, correspondence information and sound data from the coded data stream; an intermediate frame generator for generating intermediate frames from the key frames and correspondence information, and an output controller for outputting the key frames and intermediate frames in synchronization with the sound data.
