Abstract
Abstract A system for building scaled images of an original in which a scaled image is sequentially built by scaling different portions of the original image and by combining the scaled different portions to obtain the scaled image. The system includes an image input section, an image portion selector, an image scaler, and a combiner for combining scaled images such as through a binary "OR" operation. The portion selector selects respective first and second portions of the original, and the scaler forms respective first and second images of the selected portions, both the first and second scaled images having the target size. The combiner combines the first and second images so as to obtain a scaled image, the amount of detail in the scaled image being superior to the amount of detail in either the first or second images.
