Point AF (Autofocus)
For best results when using point AF, select an area within the image with contrast or detail. The
point AF function cannot focus on a low-contrast area such as a cloudless or overcast sky.
Click the point-AF button. The mouse pointer will
change to the point-AF cursor. To cancel the function,
click the point-AF button again.
Click on the area of image to be used for focus.
Autofocus will begin and a new prescan will be dis-
played.
The DiMAGE Scan autofocus system uses the CCD sensor to focus the scanner. When the
autofocus-at-scan option is selected in the preferences window, the autofocus system uses
the center of image to determine focus. This normally results in an excellent scan when the
film plane is flat. However, if the film is warped or curled, the scanner can be focused using
point AF or manual focus.
