| 1. A mobile terminal capable of being changed from an open condition into a closed condition, comprising:
a processor which executes program processing; and
a clock controller capable of changing a frequency of a clock signal to be fed to the processor;
wherein the clock controller controls the frequency of the clock signal so as to become a first frequency when the mobile
terminal is in the open condition, and controls the frequency of the clock signal so as to become a second frequency lower
than the first frequency when the mobile terminal is in the closed condition, and
wherein the clock controller controls the frequency of the clock signal so as to become a frequency higher than the second
frequency when a specific processing is executed even if the mobile terminal is in the closed condition, and controls the
frequency of the clock signal so as to become the second frequency after the execution of the specific processing is completed.
