interface connection
The connection between the scanner and the computer. This can be
either a USB, parallel, or SCSI connection depending on the model of
scanner and your operating system.
interpolated resolution
Resolution that is changed in the scanning software rather than in the
hardware. For example, if your scanned image is 600 dpi, you might be
able to enhance it to 1200 dpi in the scanning software. This is useful
for enlarging small images.
interpolation
The process of increasing the resolution of an image by the addition of
new pixels throughout the image, the colors of which are based on
neighboring pixels.
invert
To reverse the colors in an image (for example, in a black-and-white
image, black areas are turned white and white areas are turned black).
item
The physical drawing, photo, collage, etc. you place in the scanner to
scan. Once it is scanned, it is referred to as an image or scanned
image.
j
jagged
Refers to the uneven transition between black and white, or areas of
color, in a scanned image. Jagged edges can be avoided by scanning
at a higher resolution than your output device, or by not scaling the
image after scanning it.
JPEG
Joint Photographic Experts Group. A compressed file format that
reduces file size and enables faster file access. This format can reduce
image quality and performance when the file is decompressed and
recompressed.
k
keyboard shortcuts
A keystroke or combination of keystrokes that allows you to quickly
accomplish common tasks.
l
landscape
The orientation of a photograph or image that is wider than it is tall.
When an image is taller than it is wide, it is called portrait orientation.
m
maximum pixel depth
This option enables higher bits per pixel when the scan is sent to the
software. When it is off, 8 bits per pixel are returned for grayscale and
24 bits for color. When it is turned on, 16 bits per pixel are returned for
grayscale and 48 bits for color.
