Grayscale

An image made up of shades of gray, like a black and white photo. Generally, grayscale is either 4-bit, allowing 16 shades, or 8-bit, allowing 256 shades and providing a more photo-realistic quality.

Halftone

Halftone images are composed of a pattern of black dots that simulate grayscale, such as many newspaper photos.

Hue

Hue provides the contrast between colors, what distinguishes one color from antother.

Interpolated Resolution

The resolution of an image is enhanced by the software of the scanner driver.

Invert

Reversting the color values in an image. Inverting a color image will yield something that has the appearance of a negative. Inverting a black and white image will reverse the black with the white.

Line Art

Images that are purely black and white, such as black type writing on white paper or many line drawings.

Optical Resolution

The true resolution of the scanner determined by its hardware optics. Optical resolution is often enhanced by the scanner driver yielding an interpolated resolution.

Saturation

The amount of color or intensity in a single hue.
