PROBLEM TO BE SOLVED: To provide a biometric information processing device, biometric information processing method, and a control program which can be used to calculate calorie expenditure for many different subjects while allowing the device construction to be simplified.SOLUTION: The biometric information processing device 1 is provided in which a pulse sensor 30 and a body motion sensor 302 detect the heart rate of a subject, and an MPU 308 calculates a relative heart rate which is the relative value of the detected heart rate to the prescribed resting heart rate of the subject, calculates a relative oxygen intake based on the relative heart rate, estimates the oxygen intake from the relative oxygen intake, and calculates calorie expenditure based on the oxygen intake.COPYRIGHT: (C)2010,JPO&INPIT【課題】消費カロリーの算出に際し、多数の被験者にも適用可能であるとともに、装置構成を簡略化する。【解決手段】生体情報処理装置1は、脈拍センサ30および体動センサ302により脈拍数を検出し、MPU308は、検出された脈拍数の被験者に対応する所定の安静時脈拍数に対する相対値である相対脈拍数を算出し、相対脈拍数に基づいて相対酸素摂取量を算出し、相対酸素摂取量から酸素摂取量を推定し、酸素摂取量に基づいて消費カロリー量を算出する。【選択図】図6
