发明名称 Electronic apparatus and power supply control program for position measuring
摘要 There is obtained a communication terminal and a position measuring power source control program capable of reducing power consumption associated with position measurement in relation to use of a position measuring system by a user. A CPU 101 of an arithmetic processing module 102 activates, when a position measurement processing module 105 conducts position measurement by use of a position measuring antenna 106, a particular application program to implement, for example, a navigation system. The CPU 101 assumes that the user has no intention to use the particular application program, when the user closes a folding-type cellular 100 to turn a folding detection switch on, thereby the CPU 101 activates a timer 108, and terminates the position measurement processing after a lapse of a predetermined period of time; and a power supplying module 112 suspends supply of power to the position measurement processing module 105.

主权项 1. An electronic apparatus, comprising: a position measuring unit that at least receives signals transmitted from a plurality of satellites moving around the earth and thereby measures a receiving position; a particular application program operation control unit that controls operation of a particular application program which conducts predetermined processing by use of a result of the position measurement of the position measuring unit; a power supplying unit that supplies power for the processing of the position measurement to the position measuring unit; a particular application program use presence or absence judge unit that judges presence or absence of use of the particular application program by a user; and a power supply control unit that: (a) suspends supply of power from the power supplying unit to the position measuring unit, when the particular application program use presence or absence judge unit judges absence of the use by the user, and (b) does not suspend supply of power from the power supplying unit to the position measuring unit, when the particular application program use presence or absence judge unit does not judge absence of the use by the user, wherein when an application program of a camera is initiated, the particular application program use presence or absence judge unit judges absence of use by the user, wherein the power supply control unit comprises a timer for measuring a predetermined period of time from when the application program of the camera is initiated, and suspends supply of power from the power supplying unit to the position measuring unit, when the timer measures a lapse of the predetermined period of time, wherein a warning is displayed when the application program of the camera is initiated, the warning indicating the particular application program is stopped after the predetermined period of time.
