Composed of 文字 (character, letter) and 認識 (recognition). Often referred to by the English abbreviation OCR (optical character recognition). Particularly relevant for Japanese text, where the large number of characters (hiragana, katakana, and thousands of kanji) makes recognition technically challenging.
USAGE:
Commonly encountered in technology contexts, smartphone apps (especially translation and dictionary apps that use camera input), and office automation. The technology is especially valued in Japan for converting traditional hanko-stamped paper documents to digital formats.
