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.
