To complete your scan at a rated speed, the scanned image is
compressed by default during transmission. However, if you
wish to obtain the highest image quality, you can choose to
uncompress the image data before it is output.
To Application:
Choose if you wish to compress the image data and transfer it
from the TWAIN driver to the application. Note Bi-tonal
images are normally compressed using CCITT standard called
Group 4 (G4). Color and grayscale images are often
compressed using JPEG technology. Move the [
Image
Quality
]
slider to the right or left to increase or decrease your
image quality. Note the greater the image quality, the lower
the compression level. Default is 50%.
Note that the compression depends on your image editing
application. If your image editing application does not support
the type of compression format, then the image of the
compressed file will look abnormal.
