Abstract
A vital signs measurement system includes a plurality of light sources emitting into a subject's skin. A plurality of photo sensors receives lights reflected from the subject's skin and converts the lights to a plurality of signals. A processing module receives the plurality of signals and transforms the plurality of signals to a PPG signal by analyzing a correlation coefficient between every two ones of the plurality of signals. The vital signs measurement system improves the measurement accuracy of the physiological information of the participant by the correlation coefficient.
