PROBLEM TO BE SOLVED: To accurately count the number of steps while reducing power consumption.SOLUTION: A portable terminal 1 comprises: an acceleration sensor 30 which outputs an acceleration value a sub-processor 60 which generates walking information about users walking on the basis of the acceleration value a fist counting unit 110 which counts a first number of steps ST1 which indicates the number of steps on the basis of the walking information a second counting unit 120 which counts a second number of steps ST2 which indicates the number of steps on the basis of the acceleration value a generation unit 130 which generates a first relational expression F1 showing a relation between the first number of steps ST1 and the second number of steps ST2 on the basis of both of them and a correction unit 140 which corrects the first number of steps ST1 on the basis of the first number of steps ST1 and the first relational expression F1 to output the cumulative number of steps ST10.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】消費電力を低減しつつ歩数を高い精度で計数する。【解決手段】携帯端末1は、加速度値を出力する加速度センサ30と、加速度値に基づいてユーザの歩行に関する歩行情報を生成するサブプロセッサ60と、歩行情報に基づいて歩数を示す第1歩数ST1を計数する第1計数部110と、加速度値に基づいて歩数を示す第2歩数ST2を計数する第2計数部120と、第1歩数ST1及び第2歩数ST2に基づいて、両者の関係を示す第1関係式F1を生成する生成部130と、第1歩数ST1と第1関係式F1とに基づいて、第1歩数ST1を補正して累積歩数ST10を出力する補正部140とを備える。【選択図】図1
