Sizing the Scanned Image
How much computer memory or disk space will be required to store an image depends on several factors. This section describes these factors, the relationship between physical size of an image and the image’s storage requirements, and how to adjust both of these values.
Factors that Affect Image Storage
Requirements
There are several factors that affect how much computer memory or disk space will be required to store a scanned imaged:
Type of Original The size of a scanned image depends on the type of original.
Color images require 24 bits of computer memory or disk space for each pixel or dot in the image.
In comparison, grayscale images require only 8 bits per pixel, and
