Remote PPG for Heart Rate Monitoring: Lighting Conditions and Camera Shutter Time

We investigate the effect of lighting conditions and camera shutter time on heart rate measurement using remote photoplethysmography (remote-PPG) on healthy volunteers in a simulated ICU setting. In the used range of lighting conditions (132-548 lux), there exists a range of shutter times (5-32 ms), in which a mean 3 beats-per-minute (BPM) agreement of 90-100% with the contact PPG sensor is achieved. This range is limited by the saturation of the skin pixels. These results indicate that shutter time control is unnecessary beyond avoiding saturation.
