Abstract
According to one embodiment, an information processing apparatus includes: a wireless communication part which performs wireless communication using a wireless signal of a predetermined frequency band; a detection part which detects intensity of the wireless signal; and a power source control part which supplies a power source to the detection part in a first state of the information processing apparatus, the power source control part, when a value of intensity of the wireless signal detected by the detection part is larger than a predetermined threshold value, which shifts a state of information processing apparatus from the first state to a second state in which the power source is supplied to at least the detection part and the wireless communication part.
Claims13
An information processing apparatus capable of performing wireless communication with an external device, comprising:
- a wireless communication part which performs the wireless communication using a wireless signal of a predetermined frequency band;
- a detection part which detects intensity of the wireless signal;
- and
- a power source control part which supplies a power source to the detection part in a first state of the information processing apparatus, the power source control part, when a value of intensity of the wireless signal detected by the detection part is larger than a predetermined threshold value, which shifts a state of information processing apparatus from the first state to a second state in which the power source is supplied to at least the detection part and the wireless communication part.
A power source control method performed by an information processing apparatus having a wireless communication part which performs wireless communication with an external device using a wireless signal of a predetermined frequency band and a detection part which detects intensity of the wireless signal, the method comprising:
- supplying a power source to the detection part in a first state of the information processing apparatus;
- detecting a value of intensity of the wireless signal by the detection part;
- and
- when the value of intensity of the wireless signal detected by the detection part is larger than a predetermined threshold value, shifting a state of the information processing apparatus from the first state to a second state in which the power source is supplied to at least the detection part and the wireless communication part.
