Abstract

This article describes how to minimize expensive processing in the host computer during image scanning operations. The scanning operation we are concerned with is shown in Fig. 1, which is a user's abstract view of the scanning requirement. The requirement is to copy parts of the image on the paper in the scanner, process them (scale, rotate, halftone, etc.) and then place these processed parts into a target image held in the host computer memory, or database. The resultant image may be displayed on an image display for visual verification of the scanning/manipulation process. (Image Omitted) Processing of the image data captured by the scanner is shared across the image processing resources of the system: the scanner, the display and the host computer.
