解説
問 59
Incorrectア
Performing wireless communication between devices at a short distance of about 10 cm describes NFC (Near Field Communication), which has nothing to do with OCR.
- イ
正解 OCR (Optical Character Recognition) is a technology that takes printed or handwritten characters on paper captured as an image by a device such as a scanner, performs pattern recognition on them, and converts them into editable and searchable text data. Therefore, choice イ, which states that it recognizes printed or handwritten characters and converts them into text data, correctly describes the role of OCR.
Incorrectウ
Artificially generating speech through digital signal processing describes speech synthesis, which is a different technology from OCR that turns characters into text data.
Incorrectエ
Detecting the position on a panel touched by the user's fingertip or similar describes a touch panel, which is unrelated to OCR that performs character recognition.
ここがポイント
- Definition of OCR = a technology that optically reads imaged printed or handwritten characters and converts them into text data.
- Be able to distinguish the role of OCR from those of NFC (Near Field Communication), speech synthesis, and touch panels, which are easily confused with it.
