PROBLEM TO BE SOLVED: To provide a biological information processing apparatus which calculates calories burned and its controlling method.SOLUTION: The biological information processing apparatus 1 determines whether a measured pulse rate HR satisfies conditions which are set to estimate the measured pulse rate as a pulse rate in a resting state HRrest in advance (Steps S2, S3). If the apparatus 1 determines the measured pulse rate HR satisfies the conditions, the apparatus 1 updates a set value of the pulse rate in a resting state which is stored in advance to the pulse rate HR which satisfies the conditions (Step S4).COPYRIGHT: (C)2009,JPO&INPIT【課題】ユーザに合わせた消費カロリーを算出する。【解決手段】生体情報処理装置1は、測定した脈拍数HRが、安静時脈拍数HRrestと推定可能な予め定めた条件を満たすか否かを判定し(ステップS2、S3)、この条件を満たしたと判定した場合に、予め記憶された安静時脈拍数の設定値を、該条件を満たした脈拍数HRに更新するようにした(ステップS4)。【選択図】図6
