摘要：
A method includes: sensing a portion of a human body to generate a series of image frames by an optical sensing element； determining a complexion region from each of the image frames； then calculating a central coordinate of the complexion region； determining a sample block by expanding a surrounding range from the central coordinate, for getting a complexion fluctuation waveform； comparing the central coordinate with a central coordinate of a later image frame, to calculate a displacement in a unit time for determining whether the portion of the human body is in a static state. In the static state, an operating unit performs noise filter and peak detecting for complexion fluctuation waveform, and calculates a physiological signal. The method can reduce the amount of data required to be processed in physiological signal detection, and improve the accuracy of the detection.
