PURPOSE: A portable electronic device is provided to be utilized as a solar cell for charging and input device. CONSTITUTION: A control module(15) is configured to support functions of a mobile phone. The control module controls operations of the mobile phone 1 so that processes of the mobile phone 1 are suitably performed. The control module controls a display control module(13), a charging circuit(14), a first voltage-detection module(12), etc., to detect an operation of a solar cell based on the output voltage, and performs a predefined control based on the operation as explained in more detail below. The control module is implemented or realized with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor is also implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration. In practice, the control module comprises processing logic that is configured to carry out the functions, techniques, and processing tasks associated with the operation of the mobile phone. A photosensor(5) exposes a light-receiving surface from a second opening in an upper case. The photosensor detects brightness around the mobile phone from outside light, which the light-receiving surface detects. A battery(6) is charged with voltage generated by the solar cell SC. The battery feeds power to an LCD(3), etc. That is, the battery functions as an electronic component that operates based on the voltage generated by the solar cell SC. |
