Resolution
The data in the image you have scanned is a collection of dots carrying information about brightness and
color. The density of these dots is called "resolution," and resolution will determine the amount of detail your
image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm).
The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less
detail.
How to Set the Resolution
You can set the resolution in Resolution on the
dialog.
Appropriate Resolution Settings
Set the resolution according to the use of the scanned image.

Important
• If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the
processing speed will slow down significantly, and you will experience inconvenience such as lack of
memory. Set the minimum required resolution according to the use of the image.
