Canon multipass c5500 ユーザーズマニュアル

Chapter 6

Custom tone curve files are saved in the MultiPASS directory. Use the
following steps to open a custom tone curve setting that you previously
saved.

1. On the Tone tab, click the Special Tone Curves button, and then

click Load.

2. In the Open dialog box, select the file name you want to load and

click Open.

For black and white scans, the contrast and brightness settings are
located on the C5500 tab.

Depending on the black and white option you choose for your scan, you
can adjust the contrast, brightness, or both of your preview image.

If you use halftone as your scan option, you can adjust both the contrast
or brightness of the image.

If you use threshold as your scan option (it is by definition a high
contrast image mode), you can only adjust the brightness of the preview
image.
