Abstract:
1. An imaging apparatus for creating a digital image of a document, comprising: a light source for illuminating a scan line of said document, the scan line comprising a plurality of pixels; a plurality of pixel sensors for generating a plurality of signals in response to light incident thereon; a lens for focusing light from said light source reflected from said plurality of pixels of said scan line of said document onto said plurality of pixel sensors; a color matrix filter disposed between said pixel sensors and said lens for filtering said reflected light from each pixel in the plurality of pixels of said scan line of said document into a plurality of colors prior to said reflected light being incident at said plurality of pixel sensors; and a circuit for processing said generated plurality of signals representative of said plurality of colors of said reflected light incident on said plurality of pixel sensors to generate said digital image of said document; wherein each scan line of said document is illuminated only once such that the plurality of pixel sensors corresponding to the plurality of colors of each pixel of said scan line of said document read said pixel of said scan line substantially at the same time in substantially overlapping manner in a scan line direction without overlapping in a direction orthogonal to said scan line direction.
