Operating Modes 3-1
3. Operating Modes
The MAGNUM Color Scanners work in six basic operating modes:
• 24 bit RGB color mode
• 8-bit indexed color mode
• 8-bit feature extraction color mode
• Graytone mode (256 graytones)
• B/W modes (bitmapped, 2-level and 2D-adaptive)
• B/W Copy modes with Dual 2D-Adaptive processing.
3.1 RGB mode
Full 24-bit true color mode for 16.8 million colors.
3.2 Indexed color mode
An effective method for scanning documents that display a limited
range of colors, is to map true colors to a selected color palette. The
palette is automatically generated by an adaptive color optimizing prescan of the original.
The scanner on-board color transformation to a 16- or 256-color
palette greatly reduces the data volume, increases scan speed and
minimizes disk storage requirements by only requiring 4-bit or 8-bit per
color pixel (compared with 24-bit in true color mode).
3.3 Feature extraction (classified) color mode
Real-time color classification mode sorts the observed color features
in the document into a set of color categories by on-board mapping
through a classified color LUT (Look Up Table). The classified color
LUT is generated by the user through the tools in WIDEimage and
then downloaded into the scanner. The user only has to create the
LUT once for a whole class of documents.
The scanner on-board color mapping through a 256 classified color
LUT greatly enhances clarity and quality of duplicated, faded or printed
(color dithered) documents. It improves details in complex maps or
drawings, increases scanning speed, and minimizes disk storage
requirements.
3-2 Operating Modes
3.4 Graytone mode
In Graytone mode, the actual graylevel of each pixel is scanned; 256
levels are recognized, corresponding to 1 byte (8 bits) per pixel. This
results in graytone files that are 8 times larger than uncompressed
files scanned in Line mode at the same resolution; for example, an ESize drawing scanned in graytone mode at 300 dpi has a file size of
150 MByte, compared with typical 0.4 -1.0 MByte for a compressed file
in Line mode.
3.5 B/W modes
In this mode, the MAGNUM Color Scanner outputs each scanned pixel
as a single bit, either black (1) or white (0), depending on whether its
gray level is below or above the threshold.
Both fixed level and 2D-Adaptive thresholding are supported.
3.6 B/W Copy Modes
The copy modes incorporate Dual 2D-Adaptive processing with
different combinations of ADL+ Error Diffusion Halftoning, 2DBackground suppression, 2D-Auto edge enhancement and 2DAdaptive thresholding. The copy modes are ideal scanning wide
format documents that are intended for re-printing. The ADL+ Error
Diffusion Halftoning supports visibility of graytones in printed output by
adding toned shades of gray in regions between black and white. The
copy modes are described in the table below:
Copy Mode Image Processing Usage

Operating Modes 3-3
3.7 2D-Sharpening, 2D-Softening and 2D-Blur
Through the WIDEimage and JETimage applications, you can
manually set and control sharpening, softening and blurring filters,
giving you rich possibilities for combining effects to obtain perfect
enhancement results.
For example, you may have an image with details (such as text or
lines) you wish to sharpen. But if the image also contains large
concentrated areas of colors or graytones, sharpening will make
unwanted noise to appear in the scanned image. By using the sharpen
filter together with the blur filter, you can obtain the desired sharpened
edges without creating the unwanted noise. Both filters can be set at
different levels for ultimate control of effects.
The B/W Copy Normal scanning mode incorporates 2D-Auto edge
enhancement, with automatic, on-the-fly sharpening of your image.
3.8 Resolution in all modes
The distance ( both horizontal and vertical ) between each pixel at
resolutions representatively* used is:
200 dpi 0.1270 mm
300 dpi 0.0846 mm
400 dpi 0.0635 mm
600 dpi 0.0423 mm
800 dpi 0.0317 mm
MAGNUM Color Scanner resolution is setable in 1 dpi increments
from 50 to max. scanner resolution (800 or 600 dpi).
The resolution in dpi is always set from the WIDEimage or JETimage
interface.
