System and method for scanning a document

摘要

A system and method in a scanner for acquiring a number of sensor spots to create a digital image therefrom are provided. The system comprises a plurality of light sources positioned to project an amount of light at a scan target. The light sources are preferably red, blue, and green. The system also includes a contact image sensor positioned to receive an amount of reflected light from the scan target. The contact image sensor includes a number of sensors arranged in a nonlinear pattern. The scan target is moved relative to the contact image sensor or vice versa during the scan operation using suitable apparatus. The light sources are alternatively illuminated to obtain sensor spots from the scan target via the sensors. The sensor spots are stored in memory and an image is generated therefrom.
