GLOSSARY
baud rate
A measure of the speed of data transmission. Usually equivalent to
bits per second.
bi-level data
Image data that uses 1 bit per pixel. A single bit of digital data that
can express only 1 (light) or 0 (dark) represents a pixel.
bit
A binary digit (0 or 11, which is the smallest unit of information
used by a computer, scanner, or printer.
bit/pixel
Indicates the number of bits allocated for a pixel. The larger the
value, the more detailed the pixel.
brightness
A scanner function to lighten or darken the output image data.
carriage
A component of the scanner that contains the optical sensor and
light source for scanning. The carriage moves inside the scanner to
perform the vertical scan while the sensor performs the horizontal
scan.
color correction
A method of adjusting the color image data for a particular type of
device so that the reproduction more closely matches the original
colors.
data format
A scanner function used to determine how many bits are used to
represent a pixel. The number of bits per pixel determines how
many shades of gray or colors the scanned image can represent.
