<p><P>PROBLEM TO BE SOLVED: To provide a method for creating data of change factor information and a signal processor enabling practical signal recovery even if the data of change factor information is unknown. <P>SOLUTION: A method for creating change factor information includes: setting data of arbitrary change factor information as data of first change factor information; creating comparison data from arbitrary signal data by utilizing the data of the factor information (1); comparing data of an original signal or processed data of the data of the original signal with the comparison data (2); creating first recovery data by delivering data of obtained difference to the arbitrary signal data by utilizing the data of the first change factor information (3); using the first recovery data as substitute for the arbitrary signal data if necessary to repeat the same processing (4); and creating data of new change factor information, differing from the data of the first change factor information, from the recovery data, the data of the original signal, or the processed data of the data of the original signal obtained as the result of the repetition of the foregoing processing (5). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
