To reproduce an image of more than 2 bits/pixel/color,

however, the output device should also be capable of

producing the same tones. Many displays and printers cannot

deal with this and are limited to monochrome without

gradations, or to 8 or 16 colors.

The data format chosen also affects the amount of data

necessary for scanning and storing an image. The larger the bits

per pixel value chosen, the larger the amount of image data

becomes.

Brightness

One of seven brightness levels can be chosen for scanning.

Medium is the normal setting.

It is better to use darker settings for line art, or faint original

images, and to use lighter settings for darker original images.

The brightness can be combined with any other function.

The graph below shows the differences between the brightness

settings when the gamma correction is set for the CRT Display

A setting.
