Abstract
When an operation such as the operation of the shutter release button or the closing of the cover to the film container compartment is performed, any operation such as charging that was underway is stopped once and checking of the battery voltage level is performed with reference to reference levels, wherein it is determined whether or not any such operation was underway when either of said operations was performed, and if any such operation was underway, that operation is stopped once, and the battery voltage level is checked with reference to reference levels that are reduced by a preset amount. Consequently, an accurate check of the battery voltage level may be performed with regard to the battery voltage that had fallen due to the carrying out of such operation but that is rising to the original voltage level due to that operation being stopped.
