PROBLEM TO BE SOLVED: To provide an electronic apparatus including a solar battery that prevents display density from changing depending on a change in the amount of power generation of the solar battery, and can maintain constant display quality of the apparatus.SOLUTION: Every time voltage data (Vs) detected by a voltage detection A/D conversion unit 21a of a control unit (CPU) 21 is determined to have been decreased to a necessary drive voltage for normal operation of 1.5 V or less, a display digit number N operated in a display unit (displays maximum of 12 digits) 14 is reduced by one stage (three digits) and limited; and every time the voltage data (Vs) is determined to have been recovered to 1.6 V or more, the display digit number N is increased by one stage (three digits) to be operated. |
