Embodiment Construction
[0024] In a specific embodiment of the present invention, both the encoding end and the decoding end use the disparity vector as a reference vector to perform inter-view prediction on the encoded macroblock, and the encoder transmits the above disparity vector information to the decoding end, so that the decoding end can know that the encoding end performs visual prediction. The reference vector used for inter-prediction ensures the accuracy of encoding and decoding, improves the accuracy of inter-view prediction, and reduces the amount of coding.
[0025] The encoding end may encode and transmit the disparity vector information in image-level auxiliary information, such as image header information or slice header information. In addition, the above disparity vector information may be the disparity vector itself, or may be depth information. When the disparity vector information is depth information, after converting the above-mentioned disparity vector as a reference vector i...
