Patent ID: 7359093

Claim:
A system for streak detection in a scanning device, comprising: an imaging array comprising at least one full color spectrum channel set of rows of positionally discrete sensors usable to isolate individual colors for color reproduction, and at least one clear channel row of positionally discrete sensors; an interface that transmits image data obtained from each of the plurality of rows in the at least one full color spectrum channel set of rows of positionally discrete sensors to an image data estimating device, and from the at least one clear channel row of positionally discrete sensors to an image data comparing device; an image data estimating device that integrates the image data from each of the plurality of rows in the at least one full color spectrum channel set of rows of positionally discrete sensors to generate an estimate of clear channel image data for comparing to actual clear channel row image data; and an image data comparing device that receives the actual image data from the at least one clear channel row of positionally discrete sensors and compares that data to the estimate of the clear channel image data generated in the image data estimating device to derive clear channel error data.
