Abstract
Discusses factors controlling the speed of image and text processing other than those related to the scanning software. A flatbed scanner taker around 45 seconds to scan a sheet of A4. The computer itself imposes a limit on speed. File size makes demands on resources. A4 ASCII files take about 3,5K, formatted word processed text 7,5K. A4 images require 0,9Mb for black and white, 7 Mb for grey scale and 21,1Mb for colour. Evaluates uses for scanners and compares them with conventional entry routes
