1. Field of the Invention
The present invention relates to a portable electronic appliance and a battery and, more particularly, to a portable electronic appliance capable of using a battery as a power source and a battery capable of being used as a power source.
FIG. 1 comprises a graph showing discharge characteristics of an AA alkaline battery and an AA nickel metal hydride battery and a table relating setting of a pre-end voltage and an end voltage;
FIG. 2 is a diagram showing an example of warning signs displayed in a display section;
FIG. 3 is a block diagram of a digital camera in a first embodiment of the present invention;
A digital cameral functioning as a portable electronic appliance in accordance with the present invention and a battery used in the camera will be described as a first preferred embodiment of the present invention with reference to the accompanying drawings.
FIG. 3 is a block diagram of the digital camera 2 of the first embodiment of the present invention.
The camera 2 is a digital camera having image recording and reproduction functions. A central processing unit (CPU) 22 performs overall control of the operation of the entire camera 2. The CPU 22 functions as a control device which controls the camera system in accordance with a predetermined program and as an warning generation device which generates battery remaining energy warning information according to a kind of battery identified.
