Abstract
An image scaler which enlarges gray scale images, comprised of any number of gray scales, by any rational factor expressible as a ratio of integers between 1:1 and 2:1. The scaling method is 'data conservative' in that it always keeps all of the original gray scale pixel values of the input image, generating additional pixel values as needed to produce an enlarged output image. The scaler generates an insertion number sequence for determining where to insert vacant pixel storage locations and calculates gray scale values for those newly created vacant locations by interpolating between values of neighboring pixels.
