原昌宏

原昌宏（日语：原 昌宏／はら まさひろ Hara Masahiro，1957年—）是一名日本工程師，因在1994年發明QR碼而知名。 原昌宏於1957年在東京都出生。他就讀於法政大學電機工程系，並於1980年畢業。 原昌宏在1980年畢業後，進入豐田集團的子公司電裝工作，從事條形碼系統的開發。1992年，原昌宏被電裝公司的開發部門（後改組為Denso Wave）指派开发用於高效追踪汽車工業中使用的零件的新式條碼。有一天工作時，在午休時間的圍棋遊戲中，他認知到圍棋的黑白布局可以用來編碼信息，他還通過針對印刷品的調查得出了適用於定位圖案的獨一無二的比例，從而防止解碼軟件誤讀。該代碼於1994年作為QR碼推出。 2021年，QR碼被用於預訂和追蹤COVID-19測試和聯繫人追踪。原昌宏表示，他希望開發用於其他醫療目的的QR碼，包括X射線或心電圖數據等成像。截至2022年，原昌宏仍為電裝公司工作。 原昌宏是國際協力機構致力改善黑人教育的「人人都有學上」項目的總工程師和顧問。 Co-author of chapters 7 & 12 of "Educational development through community-wide collaboration", 2020 book "Community Participation with Schools in Developing Countries" ISBN 9780429057472 2014年，原昌宏和QR碼開發團隊的發明者們被授予歐洲發明家獎（英语：European Inventor Award）。 Meet the Man Who Invented The QR Code.
