Mirror image
The read image is symmetrically flipped to produce a mirror image of the original
detected in the main scanning direction.
Moire Patterns
Recurrent patterns on scanned images caused by incorrect settings of angles.
Noise removal
Isolated noise from an image appearing as black spots in white areas and voids in black
areas is removed to improve image quality.
Removes particles from the document image. Common particles include toner and fax
particles. Noise reduction works via an algorithm that removes pixels up to 5 x 5 dots
appart. A dot is 1/400 inch. A particle can be distinguished from a character as it is not
connected to another dot within 5 pixels.
OCR (optical character recognition)
Devices or technologies for identifying characters on documents and converting them
into text data that can be manipulated. The documents are checked by light and the dif-
ferences of light reflection are recognized as character shapes.
Operator panel
A panel consists of indicators and buttons. The operator panel is used to control scanner
operations such as, selecting features, and changing settings.
Optical sensor
A type of sensor for detecting Multi Feeding by light transmission. It also detects multi
feeding by recognizing differences in length of documents.
Outline extraction
The boundary between black and white areas is traced and the outline extracted for
closed areas.
Pad ASSY (Pad Assembly)
