ABSTRACT:
An improved platen-based image acquisition apparatus has a preview feature which enables the user to view anticipated output from the apparatus so adjustments may be made before operating the apparatus in orienting a workpiece upon the platen or in selecting image control features. The preview feature comprises a display screen visible to the user and an image-processing system coupled to the preview display screen. The image-processing system images a region of the platen to define the platen-image and forms the platen-image upon the display screen. It may simultaneously form upon the screen a frame-image for indicating the portion of the platen bounding the image to be processed so a user can determine whether a workpiece is positioned in a desired orientation before operating the apparatus. The improved image-acquisition apparatus may comprise a photocopy machine, a scanner, or a facsimile machine, and preferably the platen-image is formed in real-time characteristics.
