A system and method are disclosed which provide a look-down digital imaging device
capable of capturing relatively high resolution digital images (e.g., comparable
to traditional flatbed scanners). A preferred embodiment provides a look-down digital
imaging device comprising a linear sensor for imaging a raster line of an original
image placed substantially below the look-down digital imaging device, and a lens
for focusing reflected light from the original to such linear sensor. The linear
sensor functions much as in traditional flatbed scanners in that it captures a
single, congruent digital image of a scanned original. Most preferably, the linear
sensor is a high resolution sensor that enables a digital image to be captured
having resolution comparable to that of traditional flatbed scanners. For instance,
the linear sensor preferably enables capture of a digital image having a resolution
no less than approximately 300 dpi. As a result, such linear sensor most preferably
captures a digital image having sufficient resolution to permit optical character
recognition operations to be performed on such captured image. In a most preferred
embodiment, the look-down digital imaging device further comprises a digital video
camera for capturing video data of a target scan area. Such video data may be fed
in substantially real-time to a display (either included within the look-down digital
imaging device or included on a device to which the look-down digital imaging device
is coupled), which may aid a user in properly aligning an original within the target
scan area.
