Patent ID: 7852404

Claim:
An information signal processor for converting a first information signal containing plural informational data sets into a second information signal containing plural informational data sets and for transmitting said second information signal, comprising: storage means for storing coefficient seed data set obtained beforehand, said coefficient seed data set being coefficient data set in a production equation for producing coefficient data set that is used in an estimation equation, said production equation containing a predetermined parameter; parameter input means for inputting a value of a parameter; coefficient data generation means for generating said coefficient data set used in the estimation equation corresponding to said value of input parameter, said coefficient data set used in the estimation equation being produced according to said production equation using both the coefficient seed data set stored in said storage means and said value of parameter input by said parameter input means; data selection means for selecting plural informational data sets located on a periphery of an objective position in said second information signal based on said first information signal; and calculation means for calculating and obtaining informational data set of said objective position according to said estimation equation using both said coefficient data set generated by said coefficient data generation means and said plural informational data sets selected by said data selection means.
