♦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.
