摘要： According to aspects of the embodiments, there is provided methods and systems for correcting illumination defects in document handlers. A document handler successively moves an image-bearing sheet past an image sensor, when the edges of the document passes over the edge guide near a constant velocity transport roll the document tends to flick down onto the image sensor causing a lightness change at the edges. The proposed correction is dynamically adjusting the light source or dynamically adjusting the automatic gain control (AGC) of the imaging sensor. The method comprises characterizing an optical signal reflected from an image-bearing sheet as it passes a scan window, determining the illumination defects in at least one edge region based on the reflected signal, and adjusting the gain of the imaging sensor or the light level during receipt of the optical signal.

摘要： A scanner apparatus and method includes an optical scanner, at least one movable carriage associated with the optical scanner, and a point sensor that rides the movable carriage to measure a slow scan document width associated with a document scanned by the optical scanner. The point sensor moves in a slow scan direction with respect to the document scanned by the optical scanner. The point sensor also includes a single moving size sensor that improves a resolution by which a size associated with the document is determinable.

摘要： An illuminator includes a light guide having a light source that is configured to emit light along a length of the light guide. The light guide further includes outcoupling zones affixed to a rear portion of the light guide, each zones affixed a predetermined distance from each other zone, which are configured to direct at least a portion of the emitted light. The light guide also includes a first diffuser that corresponds to a front portion of the light guide, and which operates to diffuse emitted light exiting the front portion of light guide. The illuminator further includes a secondary diffuser that is located a predetermined distance from the front portion of the light guide forming an air gap there between. The secondary diffuser is configured to further diffuse the at least a portion of the emitted light diffused by the first diffuser after passage through the air gap.
