Overview
G
Gamma
A unit which indicates the changes in the brightness of an image. It is expressed as a function of the electric input power to
devices (e.g. scanner, display) and the brightness of the image. If the gamma rate is larger than 1, the brightness of an
image increases and vice versa. Normally, the gamma rate is set to 1 when reproducing the same brightness as the
original.
Grayscale
A method which expresses the gradation (density) from black to white in 256 levels.Suitable for scanning images such as
photographs.
H
Halftone
Reproduces the color density in black & white by using dot patterns. This method is effective for scanning images such as
photographs in black & white.
I
Image processing
Refers to processing and outputting the scanned image via specified scan parameters.
Imprinter
A printer that can print text (e.g. alphabets, numbers) on the back of the scanned document.
It can be use to manage the documents by adding a name, date or serial number on the scanned document.
Intelligent Multifeed Function
A function that excludes certain patterns of overlapping of documents that is detected as multifeed, by letting the scanner
memorize the overlap pattern.
For instance, when there is paper of the same size attached to a designated location on the page, the scanner memorizes
the location of the attachment and can be configured not to detect multifeeds for that location.
Interface
The connection that allows communication between the computer and the scanner.
