machine’s accept/reject judgment of image quality.
After document scanning has ended, machine-unacceptable digital images are converted to
visual images. These images are then reviewed by a person to determine whether or not the machine’s
image quality decision conforms to an image-quality decision made by the reviewer. Based on this
review of the machine’s operation, the user may change the previously-defined image quality
parameters so that in the future the machine will make image quality decisions that are more in line with
the image quality decision that a person would have made.
Archival storing of digital images and associated data occurs only when the machine makes a
recommendation to archive.
The Prior Art
Dinan discloses a machine based document archival method which scans a document and forms
one or more digital images and associated document data (the encoded information taught at column 5,
lines 1-5). The method detects anomalous conditions that may occur during document scanning and/or
subsequent processing and defines a plurality of image quality parameters in the form of gray scale
values. Unit 24 of Figure 1 may monitor the distribution of gray scale values in the image data and
create a histogram, which is a distribution of gray scale values which has prescribed limits. If the
distribution falls outside of the limits, a malfunction signal is generated, which signal may be utilized to
