The potential adjustments vary with the scan mode utilized in the preview. Adjustments to the scanned image may be made after the image is previewed. Grayscale, Color: Tone Adjustment p.
S T E P Tone Adjustment Use Tone Adjustment to enhance the brightness or color of the image in the preview area. Open the [Image] menu and select [Tone Adjustment], or click the [Tone Adjustment] button, to open the Tone Adjustment dialog so you can enhance the preview image. You can also click the [Auto Tone Adjustment] button so the histogram highlights and shadows are adjusted for you automatically to the optimum settings.
S T E P Histogram Settings The data comprising an image contains a variety of brightness settings ranging from shadows to highlights. These settings are represented in Plug-in Module CS-U by values ranging between 0 and 255. The difference in these values determines the image’s contrast.
S T E P How to Adjust Histograms To change the contrast in an image, the distribution of data between shadows and highlights can be adjusted by dragging the shadow and highlight marks at the bottom of the histogram. All of the data lying to the outside (left) of the shadow mark is changed to a zero value and all of the data lying to the outside (right) of the highlight mark is changed to a 255 value.
S T E P The histogram settings can be adjusted for all channels (Master) or for individual channels (R, G, B). The selectors are displayed to the left of the histogram graph (Master, R, G, B). The Master selection is unavailable if Grayscale has been selected as the scan mode.
S T E P Tone Curve Settings You can edit the tone curve directly by changing the shape of the line on the graph. When you change the setting by manipulating the curve, you can perform fine adjustments in the brightness of only the shadows, only the highlights, or both the shadows and highlights.

Glossary Auto Tone Correction A function that uses brightness/contrast and gamma value settings to automatically analyze and adjust images. Bits/Bit Numbers Each dot of a 1-bit image is assigned either black or white according to the threshold brightness value, resulting in the image being reproduced in just those two colors.
Color Channel Any one of the red, green or blue elements of a color image. Since color images are assigned 8 bits per pixel for each of the red, green and blue channels, each pixel is assigned 24 bits of data. The master channel is the composite of these three channels.
Gamma Value A function for adjusting the overall brightness of an image. A gamma value is the mathematical expression of how brightness data is converted from a scanner (the input) to a monitor or printer (the output). With 1 as the base value, a gamma value less than 1 makes an image darker, while a higher value makes it brighter.
Moiré The patterns or lines created by overlapping dots in an image. This phenomenon is found when photographs or pictures are scanned from books and magazines at low resolutions. The Descreen function helps to eliminate moiré patterns. Optical Resolution An expression of the volume of data per inch (dpi) that can be sampled by a scanner.
Scan Mode Any one of the various methods used to reproduce image data. Scan modes are distinguished by the number of bits used to describe each pixel. Plug-in Module CS-U features the following scan modes. • Color: assigns 8 bits of data for each color channel (RGB) in each pixel. Each pixel is therefore assigned 24 bits.
