Portable Terminal Device and Program

摘要

The present invention is to enable a portable telephone capable of switching to a power conservation state so as to reduce power consumption by limiting the supply of power, in which the limit on the supply of power can be partially removed immediately before the portable telephone is used, without the necessity of cancelling the power conservation mode through a mechanical button operation to restore the normal power state. In the case while the supply of power to a predetermined peripheral device (touch panel) is being limited by a power conservation mode, an acceleration sensor detects vibrations applied to the portable telephone as a first state and a brightness sensor detects the ambient brightness of the portable telephone as a second state, a CPU removes the limit on the supply of power to the predetermined peripheral device on the basis of the first state and the second state.

主权项

1. A portable terminal device including a power switching section for carrying out switching between a normal power state in which power supply is not limited and a power conservation state in which the power supply is limited to reduce power consumption, the portable terminal device further comprising:
a first state detection section for detecting vibrations applied to the portable terminal device as a first state; a second state detection section for detecting a surface state of the portable terminal device or a peripheral state thereof as a second state; and a power control section which, in the case when a power supply to a predetermined peripheral device is limited, with switching being made by the power switching section to the power conservation state, removes the limit on the supply of power to the predetermined peripheral device based upon the first state detected by the first state detection section and the second state detected by the second state detection section.
