摘要

An objective of the present invention is to lessen the occurrence of wasted data acquisition processing. A detector means (70) detects a designation operation. A designation determination means (76) determines, on the basis of the result of the detection by the detector means (70), whether an item has been designated. If it is determined that an item has been designated, a sustainment determination means (78) designates whether the state of the item being designated is sustained for a reference period. If it is determined that the state is not sustained for the reference period, a restriction means (80) restricts the acquisition of data corresponding to the designated item. If it is determined that the state is sustained for the reference period, a data acquisition means (82) acquires the data corresponding to the designated item from a storage means (34).
