WHAT IS DIGITISATION?
DIGITISING IS NOT PHOTOCOPYING….!
Process of converting paper docs, microfilm, microfiche etc.. Into electronic image files.
DIGITISATION
HARD COPY/SOFT COPYDOCUMENTS
FULL TEXT SEARCHABLEELECTRONIC DOCUMENTS

WHY IS DIGITISATION?
It came as a most wonderful and welcome tool in hands of libraries, museums, archives, societies, publishers, and others for preserving billions of paper/analogue documents in digital format.
Retain the original look with a point of view of the future relevance.
Protecting from loss or danger
Effective, efficient and purposeful use
Knowledge Transfer to the next generation

In The Past………
Paper filing and capturing documents on film were common preservation methods…….
IAEA Thomas - INIS Training Seminar-7-11 Oct 2013
Time has changed……
And the information must be stored in such media that the storage is safe and the retrieval is quick.

DIGITISATION
• THE AGE OF DIGITISATION HAS BEGUN!
IAEA Thomas - INIS Training Seminar-7-11 Oct 2013
HISTORY OF DIGITISATION…..
The first image scanner developed for use with a computer was a drum scanner. It was built in 1957 at the US National Bureau of Standards by a team led by Russell A. Kirsch.
IAEA Thomas - INIS Training Seminar-7-11 Oct 2013
HISTORY OF DIGITISATION…..
And the first image ever scanned on this machine was a 5 cm square photograph of Kirsch's then-three-month-old son, Walden.

HISTORY OF DIGITISATION
In 1975 Ray Kurzweil invented the flat bed scanner.
Kurzweil also was the inventor of text to speech technology

DOCUMENT SCANNER
A flatbed scanner is usually composed of a glass pane (or platen), under which there is a bright light (often xenon or cold cathode fluorescent) which illuminates the pane, and a moving optical array in CCD scanning.

Without VRS
= VRS AUTO-BRIGHTNESS
= Not readable !!= Repeat scanning for better result= OCR will not be perfect
VRS – AUTO BRIGHTNESS
= 100% readable != Get the best image ! = OCR will be perfect !
