Vital signs detection method, vital signs detection apparatus and a vital sign detection program

摘要

server (10) acquires image the subject taken by the camera (32). Further, the server apparatus (10) applies the independent component analysis for a plurality of signals of the optical wavelength components included in the image. Further, the server apparatus (10) converts the plurality of independent component signals obtained by the application of independent component analysis to a frequency component. Further, the server apparatus (10) based on the converted spectral into frequency components for each independent component signals, performs operations for combining the spectrum of each independent component signal. Further, the server apparatus (10) is a composite spectrum obtained by calculation, to detect the vital signs of the subject.
