Document Type and Number:
WIPO Patent Application WO/2008/069046
Kind Code:
A1
Abstract:
Provided is an electronic device capable of indicating a remaining capacity of
a battery (1) having a battery microcomputer (2) capable of outputting battery information
including remaining capacity information. The electronic device includes
a main body microcomputer (4) which acquires battery information from the battery
microcomputer (2) and calculates a remaining capacity actual value as the actual
remaining value of the battery (1) according to the battery information; and
a display unit (5) which displays the remaining capacity of the battery (1) by
control from the main body microcomputer (4). The main body microcomputer (4)
subtracts a correction margin value as an individual difference of the battery (1)
from the remaining capacity actual value so as to calculate the remaining capacity
correction value and controls the display unit (5) to display zero for the remaining
capacity in the region where the remaining capacity correction value is below
the correction margin value.
