Abstract:
In order to restrict a decrease in processing speed due to an increase in bit length of a digital signal, a mobile telephone (1001) receives an input of a digital signal having a predetermined bit length indicating a coordinate of a user-specified position on an input surface of a touch panel (1300) in a predetermined resolution from the touch panel (1300) and converts the received digital signal into a digital signal having a bit length shorter than the predetermined bit length indicating the coordinate of the user-specified position on the input surface in a resolution lower than the predetermined resolution. The digital signal after conversion is used for a process of acquiring the user-specified position.
