Appendix J: Glossary...
Histogram
A graphic representation of how brightness and darkness pixels are
distributed in an image. A histogram skewed heavily to the left indicates a
dark image, while a histogram skewed to the right indicates a light image.
Hue
The aspect of color that distinguishes it from another color (what makes a
color red or green or blue). Hue is distinct from saturation, which mea-
sures the intensity of the hue (more red, more green).
Image-editing software
Software that is used to edit images, such as Adobe Photoshop.
Image enhancement tools
Tools in your scanning software for adjusting the color and quality of
images. These tools include Brightness, Contrast and Exposure; Shadows
and Highlights; Tints; Curve; and Filters.
Image Type
The way you wish an image to be scanned and processed. ScanWizard lets
you reproduce an image as halftone, line art, grayscale, or color.
Imagesetter
An output device used to render high-resolution images or documents on
photographic paper or film.
Interpolated resolution
Resolution enhanced through software; thus also known as software-
enhanced resolution. For instance, if your optical resolution is 300 dpi,
you may be able to enhance images up to 600 dpi through software
interpolation. Interpolated resolution may capture less detail than the
optical, but it is useful for certain tasks, such as scanning line art or
enlarging small originals.
Line art
A type of single-bit image that is just purely black and white, such as a
pencil or ink sketch. Line art may also include one-color images, such as
mechanical blueprints or drawings.
