While non- contact blood pressure measurement methods using RGB images are available, they prove ineffective under low-light conditions. In addition, Visible light penetrates only the skin\u2019s capillaries, failing to reach deeper vessels like arteries. In contrast, near-infrared (NIR) light penetrates deeper into the skin, reaching the arterial layer. By integrating visible and NIR light, we can capture information from both capillaries and arteries. This research proposes a method that combines visible and NIR light to improve blood pressure measurement accuracy. The performance of this combined approach was compared with methods that rely solely on either visible or NIR light. For our experiments, an RGB-NIR camera, capable of simultaneously capturing both RGB and NIR video images, was utilized.<\/jats:p>","DOI":"10.1007\/s10015-025-01015-3","type":"journal-article","created":{"date-parts":[[2025,3,23]],"date-time":"2025-03-23T07:42:44Z","timestamp":1742715764000},"page":"484-492","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Performance evaluation of blood pressure estimation using an RGB-NIR camera"],"prefix":"10.1007","volume":"30","author":[{"given":"Sae","family":"Kawasaki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Kinefuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuta","family":"Hino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Kobayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoji","family":"Kawahito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norimichi","family":"Tsumura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,3,22]]},"reference":[{"key":"1015_CR1","first-page":"95","volume-title":"Clinical methods: the history, physical, and laboratory examinations","author":"HK Walker","year":"1990","unstructured":"Walker HK, Hall WD, Hurst JW (1990) Clinical methods: the history, physical, and laboratory examinations, 3rd edn.
