[Compression] tab
■
Compression rate:
Control the compression rate to specify the size of the file for the scanned image.
The compression rate is controlled by moving the slider.
The larger the compression rate number is specified, the higher the compression rate is
set and the smaller the file size becomes.
■
Enable High Compression:
When this check box is selected, the compression rate increases compared to the
ordinary compression method and the file sizes becomes even smaller.
ATTENTION
When the compression rate is increased, the quality of scanned images
deteriorates.
ATTENTION
This function compresses characters and backgrounds on the
document separately. So using this function on the document which
mostly contains text characters, the file size becomes smaller while
keeping the quality of the characters as they are. Meanwhile, this func-
tion is not appropriate for scanning photographs or figures, because
such drawings are recognized as background and compressed as
such, so the qualities of such images will deteriorate.
