Abstract
A number-of-pixels conversion apparatus for converting the number of pixels of an original image or a display apparatus using the same has an interpolation coefficient generator for generating an interpolation coefficient that is obtained by a function with the distance between an interpolation pixel and a reference pixel, said function has a first derivative that is smaller than −1 at least in a partial range, whereby the apparatus enables a pixel data interpolation process that produces a post-conversion image that is low in the degree of blurring even if the original image has a steep density variation.
