The color tone may be adversely affected. Selectable settings depend on color mode settings. Scanning may take longer when you use Image Settings. Image correction results may not be reflected in the preview image. Image Settings allows you to set the following items: Auto Tone When this is set to ON, the brightness of the specified portion of the image is automatically optimized. The result of the color adjustment will be reflected in the entire image. This setting is ON by default. Important You can set Auto Tone after preview. You can set this setting when Recommended is selected on the Color Settings tab of the Preferences dialog box. When you click Multi-Crop, this setting turns to ON and you cannot change it. Note When previewing or scanning images with consistent color tone (such as the sky), the color tone may change from the source image due to the Auto Tone function. In that case, set Auto Tone to OFF. Unsharp Mask When this is set to ON, the outline of the subjects is emphasized to sharpen the image. This setting is ON by default. Descreen Printed photos and pictures are displayed as a collection of fine dots. Moire is a phenomenon where dots may interfere with each other and cause uneven gradation and a stripe pattern in the image. Descreen is the function for reducing this moire effect. This setting is OFF by default. Note
