Abstract

A multiple image scanner that performs a single scan of a document containing different types of images (e.g., text and graphics) and sends multiple renditions of the same document from the scanner to a host computer (e.g., one high resolution gray scale image and one low resolution high bit depth color image; or one high resolution, low bit depth gray scale or monochrome image and one low resolution, high bit depth gray scale or monochrome image; or one high resolution, low bit depth color image and one low resolution, high bit depth color image), thus greatly reducing the total amount of data sent to and processed by the host computer.
