Canon f20 소프트웨어 가이드

You can scan two or more photos (small documents) at one time using 
Multi-Photo Scan (Simple Mode) or Multi Crop (Advanced Mode).
Each photo will constitute as one image.

Multi-Photo Scan (Scanning two or more photos at one time)
When scanning two or more photos without having to specify in detail 
such things as the scanning area, use Multi-Photo Scan in Simple Mode.
However, photos that have an overall whitish appearance or have a 
whitish border may not be cropped accurately. Also, documents other 
than photos (particularly documents printed on white paper, hand-
written text, business cards etc.) may also not be cropped accurately.

Automatically there is a correction of documents that are not straight. 
However this will not happen if the image is off by more than 10 degrees.

The document is scanned in the Color Mode of Color and Resolution of 
300 dpi.
