Heart rate detection device, heart rate detection method and program

摘要

The detection accuracy of heart rate is improved, and the detection time of heart rate is shortened.Heart rate detection deviceA picture of the user's body table.A heart rate detecting section 16 is provided for detecting the heart rate using the brightness of the photographed image of a plurality of frames photographed in the time series.The heart rate detecting section 16 comprisesThe sum of the brightness of the photographed image of each frame is calculated.The oscillating wave representing the time change of the sum of the luminance is delayed by a predetermined time.According to the period of the peak when the difference becomes small in the waveform of the difference between the oscillatory wave before delay and each vibration wave after delayThe heart rate is calculated.
