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: conversion information input means for inputting conversion information about a format or size conversion, said first information signal being different from said second information signal; information conversion means for converting the conversion information input by the conversion information input means into positional information about a target position in said second information signal; first memory means for storing coefficient seed data, said coefficient seed data being used in a production equation supplied with said positional information to produce coefficient data for use in an estimated equation; first data selection means for selecting a plurality of first information data located in a periphery of said target position in said second information signal, based on said first information signal; calculation means for calculating and obtaining information data of said target position based on said estimated equation using said coefficient data and said selected plurality of first information data; second data selection means for selecting a plurality of second information data located in a periphery of said target position in said second information signal, based on said first information signal; and class detection means for detecting a class at said target position, based on said second information data selected in said second data selection means.
