This paper presents a novel method for remote plethysmographic imaging using ambient light and a simple consumer-level digital camera. The authors demonstrate that heart and respiration rates can be quantified up to several harmonics, with the green channel showing the strongest signal due to the absorption peak of (oxy-)hemoglobin. The red and blue channels also contain plethysmographic information. The study shows that ambient light photo-plethysmography can be useful for medical purposes such as characterizing vascular skin lesions and remote sensing of vital signs for triage or sports purposes. The results highlight the potential of using ambient light for non-invasive and non-contact pulse oximetry and PPG imaging, which has not been previously demonstrated. The authors discuss the limitations and future directions, including the need for improved positioning, lateral synchronization, and more homogeneous illumination to reduce artifacts and improve spatial resolution.This paper presents a novel method for remote plethysmographic imaging using ambient light and a simple consumer-level digital camera.
