Grayscale
Grayscale refers to a single-channel image made up of 256 shades of gray,
ranging from white to black, that represent all tones in an image.
Halftoning
A method of simulating intermediate tones in black-and-white images by
varying the patterns of dots and lines. Halftoning is usually used for
photographs, or other images with intermediate tones, scanned in Black
and White.
Histogram
The Histogram displays the distribution of bright and dark pixels for each
color channel in the previewed image. The Eyedropper tool on the
histogram graph lets you redefine the tonal profile.
Magazine-Reduce Moiré / Descreen
Moiré patterns are caused by poor dithering as a result of scanning images
from published materials, such as newspapers, magazines and books.
When this feature is on, moiré reduction smoothes the overall appearance
of the image and enhances image quality.
Multi-Photo Mode / Multi Crop
Multi-Photo Mode or Multi Crop is a function used to scan two or more
photos in a single operation. Each image will appear in individual window
in the application program. (See Chapter 4 for details.)
