    • The invention relates to a coding apparatus for embedding second data into first data without deteriorating the first data and a decoding apparatus for decoding coded data into original first data and second data without deteriorating those data. The invention provides a coding apparatus which has a memory for storing at least partial data of first data, and embeds second data into the first data by rearranging, according to the second data, the at least partial data of the first data that is stored in the memory. The invention also provides a coding apparatus for decoding coded data in which second data is embedded and at least partial data of the coded data has been subjected to rearrangement by using one of a plurality of rearrangement patterns. The decoding apparatus calculates correlation between adjacent data for each rearrangement pattern, and decodes the original first data and the second data according to a rearrangement pattern that is determined based on the correlation.

    • The invention relates to a coding apparatus for embedding second data into first data without deteriorating the first data and a decoding apparatus for decoding coded data into original first data and second data without deteriorating those data. The invention provides a coding apparatus which determines change subject data and change data based on a frequency distribution of at least partial data of the first data, and embeds second data into first data by causing a change from the change subject data to the change data according to the second data. The invention also provides a decoding apparatus which determines change subject data and change data based on a frequency distribution of at least partial data of coded data in which second data is embedded, and decodes the coded data into original first data and restores the second data that is embedded in the coded data by restoring the change subject data from the change data.

    • A picture reducing circuit 1 reduces a supplied original picture. An upper hierarchical level picture memory 2 stores an input upper hierarchical level picture. A predictive tap obtaining circuit 3 extracts a predictive tap from the upper hierarchical level picture stored in the upper hierarchical level picture memory 2 and outputs the extracted predictive tap to a predictive coefficient calculating circuit 4, a pixel value updating circuit 5, and a mapping circuit 6. The predictive coefficient calculating circuit 4 generates an observation equation using the predictive tap as student data and pixels of an original picture corresponding thereto as teacher data, solves the observation equation, and generates predictive coefficients. The pixel value updating circuit 5 generates an observation equation using the predictive coefficient as student data received from the predictive coefficient calculating circuit 4 and original picture data corresponding thereto as teacher data, solves the observation equation, and simultaneously obtains optimum values of a plurality of updated pixel values corresponding to given coefficients.
