| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 102 === In this thesis, we developed an Android APP to detect the heart rate in real time using built-in camera on the smartphone. The green-color signal of camera is transformed into the power spectrum by Fast Fourier Transform (FFT). Then, we find out the maximum peak and calculate the heart rate value from the power spectrum. In the experiment results, the average accuracy rate is 97.98% and 98.01% on an adding light environment and the normal light environment separately.
