IPA IP 2025 Question 81
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問81, translated into English. ITPEC is based on the same exams.
What is the term for the technology that reads printed characters and handwritten characters from an image of a paper document read with an image scanner, and converts them into text data?
Explanation
OCR — optical character recognition turns an image of characters into character codes, that is, text data.
An image scanner only produces a picture of the page: dots of light and dark. OCR software analyses that picture, recognises the shapes of printed and handwritten characters, and outputs them as text that can be searched, edited and stored. A paper form scanned and run through OCR can then be entered into a system without retyping it.
Answer (d)
Why not others:
- •(a) CCD — a charge-coupled device is the image sensor inside scanners and cameras that turns light into electrical signals; it captures the image but does not recognise characters
- •(b) DVI — Digital Visual Interface is a standard for connecting a display to a PC
- •(c) GPU — a graphics processing unit is a processor for parallel computation such as image rendering
Key rule: A scanner captures an image; OCR turns the characters in that image into text data (OMR reads marks, not characters).
