Abstract
A scanner for generating digital image signals representing an object on a physical medium includes a detector and an analog-to-digital converter. The detector generates analog signals representing the object on the physical medium. The analog-to-digital converter converts the analog signals to digital image signals. The scanner is coupleable to an external processor by a high-speed serial bus that enables the scanner to transmit the digital image signals to the external processor without interim storage in an on-board buffer. The external processor may perform various imaging routines on the raw digital image signals from the scanner in real time, eliminating a need for an on-board processor in the scanner.
