Abstract
This camera performs battery checking which corresponds to the respective photographing modes at the time of presetting the various photographing modes. This battery check calculates an added electrical quantity between an electrical quantity consumed for 5 minutes, during which an auto-power off mechanism is operated in a state where a photographing mode is set and an electrical quantity required for the time from the start of the photographing under this photographing mode to completion of the photographing under this photographing mode in association with the selected photographing mode. Then, the added electrical quantity thus calculated is compared with a residue of the battery for a camera power source, and, only when the residue of the battery exceeds the added electrical quantity, presetting of the photographing mode is permitted. When presetting of the photographing mode is permitted with this arrangement, photographing can be carried out reliably until the execution of the photographing mode is completed.
