Abstract:
1. An information signal processor for converting a first information signal including plural sets of informational data into a second information signal including plural sets of informational data, comprising: parameter-setting means for setting values of plural parameters in connection with said second information signal; first memory means for storing coefficient seed data, said coefficient seed data being coefficient data in a production equation for producing coefficient data to be used in an estimated equation, said production equation being classified in a hierarchy in more than one layers, the lowest layered production equation including said plural parameters and said coefficient seed data; coefficient data generation means for generating said coefficient data to be used in the estimated equation corresponding to the values of plural parameters set by said parameter-setting means, said coefficient data in the estimated equation being produced according to the production equation classified in a hierarchy in more than one layers using said coefficient seed data stored in said first memory means and said set values of plural parameters; first data selection means for selecting plural sets of first informational data located in periphery of target position in said second information signal, based on said first information signal; and calculation means for calculating and obtaining informational data of said target position based on said estimated equation using said coefficient data generated in said coefficient data generation means and said plural sets of the first informational data selected in said first data selection mean.
