Abstract:
An information processing apparatus including: a sound wave sensor that outputs a sound wave and receives a reflected wave of the output sound wave; a control unit configured to measure an amplitude of a sound wave, at predetermined time intervals, which is received by the sound wave sensor after the sound wave sensor outputs a sound wave; and a power control unit configured to shift the information processing apparatus from a first power state into a second power state where power consumption is larger than that in the first power state, on a basis that the amplitude of the sound wave measured by the control unit is larger than or equal to a threshold value, wherein in a case where a number of times amplitude of a sound wave measured by the control unit is larger than or equal to the threshold value during a predetermined period of time is larger than or equal to a predetermined number of times, the control unit maintains the power state of the information processing apparatus in the first power state.
