Abstract
In an electronic device, a pulse rate measuring unit measures user's pulse rate. For example, the pulse rate measuring unit obtains a change in blood flow from a light passing through a user's fingertip, and measures user's current pulse rate based on it. A pulse rate memory unit has previously stored user's previous pulse rate. A pulse rate calculator calculates the user's pulse rate while changing a ratio of the user's current pulse rate measured by the pulse rate measuring unit to the user's previous pulse rate previously stored in the pulse rate memory unit after starting to measure the user's pulse rate. The user's pulse rate calculated by the pulse rate calculator is displayed as the user's pulse rate on a display unit.
