Blood oxygen saturation measuring is crucial for the diagnosis of disease severity. Despite the great efforts in non‐contact vital signs monitoring by image photoplethysmography (IPPG) technology, the high‐efficiency acquisition of transient image data is still challenging and generally requires complicated data processing processes. In this paper, we demonstrated a novel method for rapid measurement of blood oxygen saturation. A snapshot multispectral imager was employed in the proposed solution to transiently capture changes in spectral image information from facial tissue skin.
