Test Scanner Button

The Test Scanner Button on the Scanner sheet starts diagnostic
tests and reports if there are any problems with the scanner.

Text Enhanced

A feature used by ScanGear CS to increase the accuracy of text
scans. When Text Enhanced is the scan mode, images are scanned
as Grayscale (8 bits per pixel) and converted to Black and White (1
bit per pixel) using Canon ImageTrust processing software.

Threshold

In a Black and White image, the point at which a gray pixel is
determined to become either black or white. The Threshold slide
bar is on the Scanner sheet. Adjust the Threshold value when you
are scanning a grayscale or halftone original with Black and White
selected as the Scan Mode.

Tone

The shading and combination of colors in the image.

Tone Curve

The curve displayed with the Tone sheet tools to indicate the
Black-, Mid-, and White-point tones in a color or grayscale preview
image. You cannot edit the curve except with the Special Tone
Curves tool.

Tone sheet

The Tone sheet contains tools that let you adjust and correct the
image tone. The Tone sheet tools include Auto Tone, Contrast/
Brightness, Gamma, Histogram, and Special Tone Curves.
