ELECTRONIC APPARATUS, METHOD FOR CONTROLLING ELECTRONIC APPARATUS, AND PROGRAM

To provide an electronic apparatus that can satisfactorily detect an object, a method for controlling an electronic apparatus, and a program.SOLUTION: An electronic apparatus comprises a control unit that detects an object based on a transmission signal transmitted as a transmission wave, and a reception signal received as a reflected wave of the transmission wave reflected on the object. The control unit detects the object based on the difference between a logarithm value of a first signal strength of a first signal that corresponds to the distance of the object from the electronic apparatus and that is calculated based on a first transmission signal having been transmitted at a first time and a first reception signal received as a reflected wave of the first transmission signal, and a logarithm value of a second signal strength of a second signal that corresponds to the distance of the object from the electronic apparatus and that is calculated based on a second transmission signal having been transmitted at a second time being a time before the first time and a second reception signal received as a reflected wave of the second transmission signal.SELECTED DRAWING: Figure 2 【課題】物体を良好に検出し得る電子機器、電子機器の制御方法、及びプログラムを提供する。【解決手段】電子機器は、送信波として送信される送信信号、及び送信波が物体で反射した反射波として受信される受信信号に基づいて、物体を検出する制御部を備える。制御部は、第１の時刻に送信された第１の送信信号と、第１の送信信号の反射波として受信される第１の受信信号に基づいて算出された、物体の電子機器からの距離に対応する第１の信号の第１信号強度の対数値と、第１の時刻よりも前の時刻である第２の時刻に送信された第２の送信信号と、第２の送信信号の反射波として受信される第２の受信信号に基づいて算出された、物体の電子機器からの距離に対応する第２の信号の第２信号強度の対数値との差分に基づいて物体を検出する。【選択図】図２
