48 VISIONEER ONETOUCH 9320 USB SCANNER INSTALLATION GUIDE
To adjust the color settings:
1. From the Channel drop-down menu, choose the individual color
(Red, Green, or Blue) that you want to use as the basis for adjusting
the image, or choose All to adjust them together.
2. From the Edit Style drop-down menu, choose the type of color
editing that you want to use:
■ Gamma—The response curve changes as you change the gamma
setting; you can also change the saturation and hue settings.
■ Freestyle—You can drag points and sections of the response
curve to create interesting and unusual color effects. Put the
pointer on the curve and drag left, right, up or down. The image
changes its colors in response to the new curve. The x and y
numbers at the bottom of the response curve indicate the exact
position of the pointer on the curve. The Gamma slider remains
fixed when you use the Freestyle option.
3. Drag the Gamma, Saturation, and Color Hue sliders to the left to
decrease the settings or to the right to increase the settings.
You can also type a number directly into the setting boxes, or click
the up and down arrows next to the boxes.
4. Click Reset to return the settings to their original numbers.
The upper Reset button is for the gamma setting, the lower one is
for saturation and hue.
5. To save the settings of a response curve, click Save.
Saving is available for settings created with the Freestyle editing
option so you can load and reuse the exact settings on other images.
This is especially helpful for complex Freestyle response curves.
A dialog box opens that lists the names of previously saved settings.
Type a name for your new settings and click OK.
6. To reuse a saved response curve setting, click Load.
A dialog box lists the names of your previously saved settings. Select
the one you want and click OK.
