Title:
ELECTRONIC APPARATUS AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/133013
Kind Code:
A1
Abstract:
Proposed is an electronic apparatus, which is capable of charging a secondary battery even in the cases where intensity of light applied to a solar cell is weak, and which is capable of performing data communication using the solar cell by suppressing influence of ambient light. The electronic apparatus is provided with a control circuit (202) and a resistor (205). The control circuit (202) receives data on the basis of an output voltage of a solar cell (201). The resistor (205) is connected between the electrodes of the solar cell (201). The control circuit (202) controls a resistance value of the resistor (205) on the basis of whether operations for receiving data is being performed or not.
