  • Publication number: 20200088854
    Abstract: The present technology relates to a distance measuring device and a distance measuring method that can improve the accuracy of distance measurement. A control unit controls a light emitting operation by supplying a light emitting unit with a light emission timing signal for controlling the light emitting operation for emitting irradiation light and controls the light receiving operation by supplying a light receiving unit with a light reception timing signal for controlling the light receiving operation for receiving reflected light. A measuring unit measures a deviation time between the light emission timing at which the light emitting unit emits the irradiation light and the light reception timing at which the light receiving unit receives the reflected light, using the light emission timing signal and the light reception timing signal. The present technology can be applied, for example, to a case where distance measurement is performed by using the ToF method.
