Black-point

The darkest portion of an image scanned as Color or Grayscale.

When you click on the image with the Black-point eyedropper, all

tones darker than the selected sample tone are adjusted to black.

See also Mid-point, White-point.

Brightness

The overall amount of lightness or darkness in an image. An

image with maximum brightness tends toward white; an image

with minimum brightness tends toward black. While contrast

refers to the range and number of tones in an image, brightness

refers to the intensity of tones.

Calibration

For scanning, calibration refers to the adjustment of color

processing for input and output devices on a computer, so that the

colors match throughout the process. For example, calibration

ensures that the color image scanned on a scanner matches the

original image when it is displayed on the computer monitor, as

well as printed on a color printer.

Canon ColorGear Color Matching

Canon’s process of matching the color profile of the input device

(scanner) with the color profile of the output device (monitor), to

yield the most accurate color image. Canon ColorGear Color

Matching is compliant with ICC (International Color Consortium)

guidelines. ICC is a group of hardware and software companies

which developed cross-platform, industry-standard guidelines for

color devices. Canon ColorGear Color Matching is also compatible

with the ICM (Image Color Matching) component of Windows 98.
