Abstract:
1. An information signal processor for converting a first information signal including a plurality of information data into a second information signal including a plurality of information data, comprising: parameter setting means for setting a value of parameter related to the second information signal; first memory means for storing coefficient seed data, said coefficient seed data being coefficient data in production equation for producing coefficient data to be used in an estimated equation and said production equation containing said parameter; term selection means for selecting at least a term of said production equation, based on a feature obtained in relation to said first information signal; coefficient data generation means for generating said coefficient data to be used in said estimated equation corresponding to the set parameter, said coefficient data in the estimated equation being produced according to the term-selected production equation from said term selection means using said coefficient seed data stored in said first memory means and a value of said parameter set by said parameter setting means; first data selection means for selecting a plurality of first information data from said first information signal located on the periphery of a target position in said second information signal; and calculation means for calculating and obtaining information data at said target position according to said estimated equation using said coefficient data generated in said coefficient data generation means and the plurality of said first information data selected in said first data selection means.
