A wristwatch includes a storing unit that stores relational data for predetermined user classifications, such as gender and body height, indicating a relationship between a traveling pitch, which is the number of steps taken by a user per predetermined amount of time, and a traveling speed which is a running speed or a walking speed. A correcting unit corrects the stored relational data based on a set of a measured traveling pitch and a measured traveling speed. A speed calculating unit calculates a traveling speed of the user from a measured traveling pitch of the user based on the stored relational data that correspond to a user classification input by the user and that has been corrected.

An electronic device has a storage unit that stores unit information relating to movement with respect to each of an elevating state and a horizontal movement state and an altitude measurement unit that measures a series of altitudes. An altitude change determination unit determines whether the movement is the elevating state or not using a first determination section having a first altitude range based on a first set of altitudes within the measured series of altitudes, and determines whether the movement is the horizontal movement state or not using a second determination section having a second altitude range smaller than the first altitude range and based on a second set of altitudes within the measured series of altitudes. A movement distance calculator reads from the storage unit the unit information corresponding to the state determined by the determination unit and calculates a movement distance based on the read unit information.

A display device includes independently driven common and segment terminals. The common and segment terminals are connected to display components divided into display blocks that are turned ON to perform a display function and are turned OFF so as to not perform the display function. A first driver drives the common terminals using a scanning signal of a predetermined period and a second driver drives the segment terminals using a segment signal synchronized with the scanning signal to correspond to a display signal, so that the display components perform a display corresponding to the display signal. The first driver separates the common terminals into common terminal blocks and drives the common terminals. The first and second drivers perform the driving so that the common and segment terminals which are connected to display blocks that are turned OFF are not supplied with a turn-off signal and are maintained at ground potential.
