Abstract:
A heart rate detection module including a PPG measuring device, a motion sensor and a processing unit is provided. The PPG measuring device is configured to detect a skin surface in a detection period to output a PPG signal. The motion sensor is configured to output an acceleration signal corresponding to the detection period. The processing unit is configured to respectively convert the PPG signal and the acceleration signal to first frequency domain information and second frequency domain information, determine a denoising parameter according to a maximum spectrum peak value of the second frequency domain information to denoise the first frequency domain information, and calculate a heart rate according to a maximum spectrum peak value of the denoised first frequency domain information.

Claim (Index 16):
A denoising method of a heart rate detection module, the heart rate detection module comprising a PPG measuring device, a motion sensor, a band pass filter and a processing unit, the denoising method comprising:\n receiving, by the processing unit, a PPG signal, which is detected by the PPG measuring device, and an acceleration signal, which is detected by the motion sensor, in a detection period; filtering, by the band pass filter, the PPG signal and the acceleration signal; converting, by the processing unit, the filtered PPG signal to a frequency domain PPG signal and generating first frequency domain information comprising a first frequency index set and a first spectrum value set associated with the first frequency index set; converting, by the processing unit, the filtered acceleration signal to a frequency domain acceleration signal and generating second frequency domain information comprising a second frequency index set and a second spectrum value set associated with the second frequency index set; identifying, by the processing unit, three frequency indexes corresponding to top three spectrum peak values in the first frequency domain information and a reference index corresponding to a maximum spectrum peak value in the second frequency domain information; determining, by the processing unit, a denoising range according to the reference index; denoising, by the processing unit, the first spectrum value set by removing spectrum values associated with the three frequency indexes within the denoising range from the first spectrum value set, and calculating, by the processing unit, a heart rate according to the denoised first spectrum value set.
