dragging a rectangle around the object or text you want to crop, click the
Auto Crop button to size the rectangle exactly to the size of the object or

Bits and Bit Depth
A bit (Binary digit) is the smallest possible unit of information on a\
computer; it represents yes or no; on or off; 1 or 0. Bit Depth is used to
describe the complexity of a graphic image.
One-bit, or bi-level, images are black and white. This is the Black and White
setting in ScanGear CS-U. Eight-bit grayscale uses 256 shades of gray to\
accurately represent most black and white photographs or gray
interpretations of color images. This is the Grayscale setting in ScanGear
CS-U. Twenty-four-bit color, also called True Color, uses three eight-bit
channels, one channel each for Red, Green and Blue, to create up to 16.7
million colors. This is the Color setting in ScanGear CS-U.
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
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
Canons process for matching the color profile of the input device (scanner)
to the color profile of the output device (monitor) to yield the most
accurate color image.
Color Channels
The red, green, or blue components of a color image. Color images contain
8 bits per pixel each for red, green, and blue channels, therefore each pixel
has 24 bits. If you are scanning a color image, you can change the
brightness and contrast of the individual red, green, and blue tones in your
image.
Color Mode
The type of scan used to scan an image, differentiated by the number of
bits per pixel. ScanGear CS-U has the following Color Modes: Color,
Grayscale, Text Enhanced, and Black and White.
Contrast
Contrast refers to the difference between the lightest light and the darkest
dark in the image. A low contrast value indicates that the difference
between dark shades and light shades is not very great. A high value
indicates a great difference between dark and light shades. While
brightness refers to the intensity of tones in an image, contrast refers to the
range and number of tones in an image.
