A portable display device includes: an acceleration sensor (51); an outputting section (511) outputting a detection signal when a measurement value changes across a reference value; a calculating section (410) calculating a duration time in which the measurement value exceeds the reference value; a judging section (411) judging whether the movement state is due to running based on an occurrence frequency of the movement state and the duration time; a setting section (412) setting a running state when the movement state is due to the running; a calculating section (413) calculating a time interval between the movement states; a continuous tap judging section (414) judging whether the movement states are due to continuous tap operations according to a judgment condition based on the duration time and time interval; and a setting range changing section (415) setting a range of the judgment condition in the running state to be broader than that in a non-running state. |
