GL-3
Hexadecimal
A base-16 numbering system(also commonly referred to as hex numbers). Since a base-16 system
requires 16 digits, numbers 0 through 9 and letters A through F are used. It is convenient to express binary
numbers in hexadecimal because fewer digits are required.
Image emphasis
Density is decreased for lighter but not completely white areas adjacent to black areas. Weakening this
emphasis eliminates spot noise or produces softened images.
Image processing
An image is read with specified parameters.
Interface
The connection that allows communication from one part of a system to another. For example, electrical
signals are transferred between the computer and scanner over an interface cable.
Inversion (Reverse-image reading)
In reverse-image reading, data is changed from black to white and vice versa.
IPC pre-set mode
While reading binary images, it is necessary to set the scanner according to the quality of the sheet to be
read. In this mode these settings can be performed in advance by corresponding each setting to a pattern
number.
IPC-2D or IPC-3D
Image processing option of this scanner.
IRAS
Initialization of the hardware.
Landscape
A document is transported and read with the long side vertical to the moving direction.
