SIGNAL-PROCESSING UNIT, SIGNAL-PROCESSING METHOD, AND SIGNAL-PROCESSING PROGRAM

摘要

The pulse wave detection device (10) acquires images. The pulse wave detection device (10) then extracts a biological region contained in the images. The pulse wave detection device (10) then generates a signal from the time series data of the pixel values of the partial image corresponding to the biological region in the images. The pulse wave detection device (10) then calculates a variation index for evaluating the degree of pulse wave disturbance contained in the signal. The pulse wave detection device (10) then controls whether or not to output the signal using the variation index.
