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 1):
A digital signal processing device, the digital signal processing device being configured to receive a PPG signal and an acceleration signal, the digital signal processing device comprising:\n a band pass filter configured to filter the received PPG signal and the received acceleration signal to respectively generate a filtered PPG signal and a filtered acceleration signal; a conversion module configured to respectively convert the filtered PPG signal and the filtered acceleration signal to\n first frequency domain information, which comprises a first frequency index set and a first spectrum value set associated with the first frequency index set, and \n second frequency domain information, which comprises a second frequency index set and a second spectrum value set associated with the second frequency index set; \n a peak value extraction module configured to identify a plurality of frequency indexes corresponding to a plurality of spectrum peak values in the first frequency domain information and the second frequency domain information; and a calculation module configured to\n determine a reference index as a denoising parameter according to a frequency index corresponding to a maximum spectrum peak value of the second frequency domain information, \n remove spectrum values, which correspond to frequency indexes of the denoising parameter, from the first frequency domain information to denoise the first frequency domain information, \n determine a heart rate index according to a denoised maximum spectrum peak value of the denoised first frequency domain information, and \n calculate a heart rate according to the heart rate index.
