♦ Image Mode
Selects an image mode for scanning the image.
Select a corresponding image mode from the list.
Black & White
Scans data by using the fixed threshold binary, black-and-white. Distinguishes black
from white by the setting in the "Threshold" of "Scanning Parameter". This scanning
mode is suitable for scanning line drawings and text documents.
Halftone (Dither)
Scans data using the halftone processing, with dithering or error diffusion. Uses the
patterns set in "Halftone" to simulate data in black-and-white. Selection of built-in
dithered patterns or error diffusion (not supported by some device models) is allowed.
This scanning mode is suitable for scanning images containing light and shadow such
as a photograph. Some scanner models do not support this option. See "Relevant
Image Scanner Specification" in the Appendix.
Gray scale
Scans data using 256-level monochrome gray scale. Light and shade in photographs
can be represented with greater fidelity. This scanning mode employs far more
memory than the Black & White mode.
Some scanner models do not support this option. See "Relevant Image Scanner
Specification" in the Appendix.
4bit Gray scale
Scans data using 16-level monochrome gray scale. Data size is smaller than "Gray
scale" selected.
Some scanner models do not support this option. See "Relevant Image Scanner
Specification" in the Appendix.
Automatic separation
Scans data distinguishing line drawing from photograph image.
If this option is selected, the line drawing part is scanned using "Black & White," and
the photograph part is scanned using "Halftone". This information is most suitable for
documents containing both photographs, and line drawings or text.
Some scanner models do not support this option. See "Relevant Image Scanner
Specification" in the Appendix.
SEE (Selective Edge Emphasis)
Scans data using the halftone processing and emphasizes line drawings and text. This
option is most suitable for emphasizing only text of documents containing both
photographs and text.
Some scanner models do not support this option. See "Relevant Image Scanner
Specification" in the Appendix.
24bit Color
Scans data using 24 bits color. This mode is suitable for scanning color photograph
and employs far more memory that Gray scale mode.
Only color scanner models support this option. See "Relevant Image Scanner
Specification" in the Appendix.
