Mobile electronic device

摘要

An electronic device is disclosed. The electronic device comprises at least one solar cell, and voltage-detection means operable to detect an output voltage of the at least one solar cell to obtain a detected output voltage. The electronic device also comprises control means operable to detect an operation of the at least one solar cell based on the detected output voltage, and to perform a predefined control depending on the operation.

1. A mobile electronic device comprising:
at least one solar cell operable to function as a user input key a first voltage-detection module operable to detect an output voltage of the at least one solar cell to obtain a detected output voltage; an adjustment module operable to amplify the output voltage; and a control module operable to:
to control the adjustment module such that the output voltage is amplified to a predefined voltage value, if an amount of light detected by a photosensor is less than a predefined lumen value;detect an operation of the user input key based on the amplified output voltage; andperform a predefined control based on the operation.
