Return to Overview
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, increase the sharpness as setting. To scan originals containing printed images or other halftones with a softer contrast, decrease the sharpness as setting. The default setting is <4> (middle).
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 decreasing the sharpness to produce a clearer image.
You can enhance the edges of original images so that faint or fine text is scanned with a sharper contrast by increasing the sharpness. This setting is particularly suited for scanning blueprints and faint pencil drawn images. |
