Abstract

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.

Clinical Relevance— Replacing spot checks by continuous
monitoring in a hospital will lead to timely detection of adverse
events. Technologies for remote-PPG will allow continuous
monitoring in a clinical setting.
