Method of displaying remaining battery power, and electronic apparatus
WO 2006095563 A1
Abstract
A method of displaying remaining battery power of a battery pack mounted on an electronic apparatus and supplying electric power to the electronic apparatus. When power is turned on, first, a first microcomputer (3) of the camera body (1) acquires information required for display of remaining battery power, the information being acquired through serial communication from a second microcomputer (7) of a battery pack (2) mounted on the camera body, and displays remaining battery power based on the acquired information. Then, the first microcomputer (3) acquires information required for verification processing, the information being acquired through serial communication from the second microcomputer of the battery pack, and based on the acquired information, the first microcomputer (3) performs verification processing by which whether or not the battery pack connected to the camera body is a genuine battery pack is determined. After the verification processing, contents of the display of remaining battery power are renewed based on information for display of remaining battery power, which information is acquired by serial communication from the microcomputer of the battery pack.
