Abstract:
1. An image display apparatus comprising: image signal input means for inputting a first image signal containing plural pixel data sets; image signal processing means for converting said first image signal input by the image signal input means into a second image signal containing plural pixel data sets and then transmitting the second image signal; image display means for displaying an image obtained by said second image signal received from said image signal processing means on an image display element; and parameter adjustment means for adjusting a value of a parameter for deciding a picture quality of said image displayed on said image display device, wherein said image signal processing means includes: first data selection means for selecting first plural pixel data sets located on a periphery of an objective position in said second image signal based on said first image signal; class detection means for detecting a class including pixel data set of said objective position based on said first plural pixel data sets selected by said first data selection means; first storage means for storing coefficient seed data set obtained beforehand for each class detected by said class detection means, said coefficient seed data set being coefficient data set in a production equation for producing coefficient data set used in an estimation equation, and said production equation containing said parameter; coefficient data generation means for generating said coefficient data set used in the estimation equation corresponding to the class detected by said class detection means and a value of said parameter adjusted by said parameter adjustment means, said coefficient data set used in the estimation equation being produced by said production equation using both said coefficient seed data set stored in said first storage means and the adjusted value of said parameter; second data selection means for selecting second plural pixel data sets located on a periphery of the objective position in said second image signal based on said first image signal; and calculation means for calculating and obtaining pixel 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 second plural pixel data sets selected by said second data selection means.
