Abstract:
1. An electronic device comprising: a reception unit that captures a positioning information satellite and receives a satellite signal transmitted from the captured positioning information satellite; a solar panel; and a reception control unit that controls the reception unit, the reception control unit including wherein the evaluation unit determines if power generation by the solar panel is greater than or equal to a first power generation evaluation threshold value, is less than a second power generation evaluation threshold value that is lower than the first power generation evaluation threshold value, or is less than the first power generation evaluation threshold value and greater than or equal to the second power generation evaluation threshold value; and wherein the mode selection unit selects the position and time information reception mode when the evaluation unit determines power generation is greater than or equal to the first power generation evaluation threshold value, selects the time information reception mode when the evaluation unit determines power generation is less than the first power generation evaluation threshold value and greater than or equal to the second power generation evaluation threshold value, and changes to a mode enabling the user to select the reception mode when the evaluation unit determines power generation is less than the second power generation evaluation threshold value.
