ITPEC IP October 2025 Question 23

Recognizing printed and handwritten characters and transforming them to text data — that is OCR (optical character recognition).

OCR takes the paper as an image, from a scanner or a camera, recognises the shape of each character and outputs its character code. The result can be edited, searched and processed like typed text, so forms, postal codes and receipts need not be keyed in by hand.

Answer (b)

Why not others:

• •(a) — wireless communication between devices about 10 cm apart is NFC, used by contactless IC cards and smartphone payment
• •(c) — creating an artificial voice by digital signal processing is speech synthesis (text-to-speech)
• •(d) — detecting where a fingertip touched the panel is a touch panel, an input device that reads positions, not characters

Key rule: OCR turns images of characters into character codes, OMR only detects marks at fixed positions, and speech recognition turns sound, not images, into text.
