Patent ID: 7283173

Claim:
An image display apparatus, comprising: image signal inputting means for allowing a first image signal containing multiple items of pixel data to be inputted; image signal processing means for converting said first image signal inputted to said image signal inputting means into a second image signal containing multiple items of pixel data, and outputting the second image signal; and image display means for displaying, on an image display element, an image formed by said second image signal outputted from said image signal processing means, wherein said image signal processing means includes: first data selection means for selecting multiple items of first pixel data 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 said pixel data of said objective position based on said multiple items of the first pixel data selected by said first data selection means; parameter inputting means for allowing a value of parameter for determining quality of output obtained by said second image signal to be inputted; pixel data production means for generating pixel data of said objective position in accordance with the class detected by said class detection means and the value of the parameter inputted by said parameter inputting means; and storage means for storing the information relevant to the value of the parameter inputted to said parameter inputting means.
