Abstract
A method of generating image data comprising digital pixel data representative of one or more images on an input scanner support. In a first step the support is scanned to generate support image data at a first resolution comprising digital pixel data representative of the support and image. In a second step support image data at a second resolution is generated from the support image data at a first resolution. In a third step the boundary of an image is determined by performing a predetermined boundary determining algorithm on the support image data at the second resolution. In a fourth step, the image data is extracted from the support image data at the first resolution by extracting pixel data within the boundary of the image determined in the third step.
