Canon CanoScan 8400F 9554A003 ユーザーズマニュアル

The CanoScan 8400F is equipped with a large 
Film Adapter Unit (FAU) and a variety of guides to
accommodate different film formats. It scans 35mm 
film (up to 12 frames), mounted transparencies (up to 
4 slides), or 120 roll film (wide range up to 6 x 22cm). 
In yet another clever innovation, the light source inside 
the FAU moves in sync with the optical carriage below 
to ensure maximum light reaches the CCD sensor. 
This in turn both improves image quality and permits
faster carriage movement for super-fast scan speeds. 
An improved clip-in FAU protective sheet allows simple,
single-handed preparation for film scanning. 

On the front of the CanoScan 8400F are four large 
scan buttons, which can be customised to perform 
the functions you use most: copying, scanning, filing,
scanning direct to e-mail or straight to PDF (Portable
Document Format). 

Before you even start manipulating your scanned images, the CanoScan 8400F
will have automatically wiped them clean of any unwanted marks. The
scanner’s Film Automatic Retouching and Enhancement (FARE) technology

uses infrared light to identify and remove defects caused by dust and scratches on the
surface of your original – defects which even the most carefully stored film can have.
The CanoScan 8400F comes with three additional features – fading correction, grain
correction and backlight compensation. Fading correction ‘resaturates’ faded colours
in old photographs, while the grain correction feature takes out any grain that is visible 
on high resolution scans of high-ASA film. Backlight compensation eliminates the
‘washed out’ look some scans can have when increased brightness is used to try and
compensate for heavily backlit images. By only adjusting the gamma in the dark parts 
of an image you’ll notice that overall quality is vastly superior.
