Application

Abbreviation of the phrase “application software.” Software designed for a specific purpose such as word processing software, spreadsheet software, database software, or a combination of these.

B

Bit

An indication of the volume of data used to describe points in an image. A 1-bit image assigns image data black or white color values depending on whether the brightness value is above or below a particular threshold value. The result is a two-color image. An 8-bit grayscale image expresses an image in 256 shades of gray ranging from white to black. A 24-bit color image assigns 8 bits to each RGB color channel, expressing each pixel in approximately 16.8 million colors.

Brightness

The relative proportion of light and dark areas. Decreasing brightness darkens the overall image; increasing brightness lightens it.

C

Color Matching

In some cases, the range of colors captured by a scanner exceeds the range that can be displayed by a particular monitor. In addition, the colors displayed for an image on the monitor may be slightly different than those output by a printer. Color Matching is the process used to make the colors captured by a scanner consistent with those shown on a display or printed on a printer.

Contrast

The degree of difference between the lightest and darkest areas of an image. Decreasing contrast lightens the dark areas and darkens the light areas; increasing it darkens the dark areas and lightens the light areas.

Control Panel

The set of Windows programs you can use to change system, hardware, software, and Windows settings.

Crop

The action of selecting only part of an image for use. Using the Crop button on the ScanGear MF toolbar, a portion of the preview image can be selected and only that portion is then re-previewed or included in the final scan.
