Liquid residual quantity detecting method, liquid residual quantity detecting device, program for implementing the method, and storage medium storing the program

摘要

A liquid residual quantity detecting method which is capable of accurately detecting the residual quantity of a liquid in an apparatus without being affected by the position of the apparatus, to thereby prevent a user from carelessly or erroneously believing that the liquid still remains. A fuel residual quantity detector detects the residual quantity of a fuel stored in a fuel storage chamber 109 a of a fuel cell 108 of a camera 100 . A microcomputer 205 provides control such that an operation for detecting the residual quantity of the fuel is executed only when the camera 100 is in its normal position.
