Display device, display control method, and computer-readable storage medium

A display control method for a display device including a display part which displays display information, the method comprising the steps of:

• detecting a state of the display device;
• starting to measure the time of a timer based on the detection result of the step;
• and
• switching the display of the display part from a normal display mode to a power saving display mode in which the display appearance differs from that in the normal display mode and power consumption is less than in the normal display mode in the case where the measured time of the timer is equal to or longer than predetermined transition time.

A computer-readable storage medium which stores a program including a series of instructions which a display device, having a display part which displays display information, causes an incorporated computer to perform, the program comprising the steps of:

• detecting a state of the display device;
• starting to measure the time of a timer based on the detection result;
• and
• switching the display of the display part from a normal display mode to a power saving display mode in which the display appearance differs from that in the normal display mode and power consumption is less than in the normal display mode in the case where the measured time of the timer is equal to or longer than predetermined transition time.
