Adjusting The Contrast (Sharpness) - Canon CLC5151 Sending And Facsimile Manual

Adjusting the Contrast (Sharpness)

This mode enables you to scan original images with a sharper or softer contrast. To scan
originals with text or lines with a sharper contrast, use [High] as the setting. To scan originals
containing printed images or other halftones with a softer contrast, use [Low] as the setting.
■ Low
If you scan an original containing halftones, such as a printed image, using the Photo mode, the moiré
effect (a shimmering, wavy pattern) may occur. In this case, you can lessen this moiré effect by using
[Low] as the setting to produce a clearer image.
■ High
4
This setting enhances the edges of original images so that faint or fine text is scanned with a sharper
contrast. This setting is particularly suited for scanning blueprints and faint pencil drawn images.
