20140121567 | ELECTRONIC DEVICE, DISPLAY CONTROL METHOD AND PROGRAM - A display control unit performs switching between internal measurement information (for example, a lap time and others) and living-body information (for example, the number of heartbeats) indicated by a living-body signal for display on a display unit, based on whether or not a receiving unit acquires the living-body signal (for example, a heartbeat signal). Accordingly, a user can switch between displaying living-body information indicated by a living-body signal on a running watch (a display unit) and not displaying the living-body information indicated by the living-body signal on the running watch, depending on whether or not a chest strap is worn. Accordingly, the user does not need to perform a user operation for switching between the display of the internal measurement information and the display of the living-body information indicated by the living-body signal. Therefore, a user's laborious job of performing a display switching operation can be reduced. | 05-01-2014 |
