Abstract:
1. An apparatus for generating coefficient data of an estimating equation used for converting a first information signal including a plurality of information data items to a second information signal including a plurality of information data items, comprising: first data selection means for selecting, based on the first information signal, a plurality of information data items located around a position of interest in the second information signal; second data selection means for selecting, based on a first learning signal corresponding to the first information signal, a plurality of information data items located around a position of interest in a second learning signal corresponding to the second information signal; similarity determination means for acquiring the similarity of the plurality of information data items selected by the second data selection means with respect to the plurality of information data items selected by the first data selection means; third data selection means for selecting, based on the first learning signal, a plurality of information data items located around a position of interest in the second learning signal; first computing means for computing coefficient seed data using information data at each position of interest in the second learning signal, the plurality of information data items selected by the third data selection means corresponding to each position of interest, and a value of the similarity acquired by the similarity determination means corresponding to each position of interest, the coefficient seed data for generating the coefficient data of the estimating equation; and second computing means for computing, based on a generation equation, the coefficient data of the estimating equation for determining the information data at the position of interest in the second information signal using the coefficient seed data computed by the first computing means and a value of the similarity that indicates the highest similarity.
