PORTABLE ELECTRONIC APPARATUS AND METHOD OF CONTROLLING PORTABLE ELECTRONIC APPARATUS

摘要

A portable electronic apparatus having excellent operability and reliably executing input operation intended by the user, and a method of controlling a portable electronic apparatus. The portable electronic apparatus has a first sensor group (G1) having continuously arranged sensor elements (L1-L4) where contact is detected, and a control section (110) for monitoring outputs of the sensor elements and performing control based on a change of a sensor element where contact is detected. The control section (110) has a first contact detection mode. In the first contact detection mode, when the control section (110) detects that contact is detected by any of the sensor elements, the control section (110) makes transition to a second state from a first state in which contact is not detected in any of the sensor elements, and when the control section (110) detects that contact is not detected continuously for a predetermined period in any of the sensor elements, the control section (110) makes transition back to the first state and performs control according to a change in contact detection in the sensor elements having occurred in the second state.
