1. A method of managing sensor information in a portable terminal including at least one sub-processor driven with lower power than at least one main processor, a sub-memory, a sensor unit controlled by the at least one sub-processor, and the at least one main processor driven with higher power than the at least one sub-processor, the method comprising:

  • collecting the sensor information through the sensor unit by the at least one sub-processor in a sleep state of the at least one main processor;

    checking a storage space of the sub-memory to determine whether the collected sensor information is able to be stored;

    deleting at least some sensor information from among sensor information which are previously stored in the sub-memory when the collected sensor information is not able to be stored, and storing the collected sensor information; and

    moving the sensor information stored in the sub-memory to a main memory to store therein when the at least one main processor is woken-up.
