1. An electronic camera comprising:
- a volatile memory that temporarily maintains image data;
a detector that detects a remaining capacity of a battery for supplying power to said volatile memory; and
a maintain time calculator that calculates a maintainable time of the image data maintained in said volatile memory based on the remaining capacity detected by said detector.

Abstract
Image data photographed by an image capturing apparatus is temporarily stored in a volatile memory. The volatile memory temporarily is supplied with power from a battery to store the image data temporarily. The remaining capacity of the battery is detected, and a maintainable time of the image data maintained in the volatile memory is calculated based on the detected remaining capacity of the battery. The calculated maintainable time is displayed on a display.

5. An electronic camera comprising:
-
a volatile memory that temporarily maintains image data;
a detector that detects a remaining capacity of a battery for supplying power to said volatile memory;
a setter that sets a desired data maintain time for said volatile memory in which the image data is maintained;
a maintain capacity calculator that calculates a maintain capacity that is a battery capacity to allow the image data to be maintained for the desired data maintain time; and
an enabled time calculator that calculates a time during which the camera is enabled based on a capacity difference obtained by subtracting the maintain capacity from the remaining capacity of the battery. - View Dependent Claims (6, 7, 8, 9, 10, 13, 14, 15, 16)

11. An electronic camera comprising:
-
a volatile memory that temporarily maintains image data to be transferred to an external memory of the camera;
a detector that detects a remaining capacity of a battery for supplying power to said volatile memory;
a maintain time calculator that calculates a maintainable time of the image data recorded in said volatile memory based on the remaining capacity of the battery detected by said detector;
a recording mode selector that selects one of a first recording mode for transferring and recording the image data to the external memory after maintaining the image data in said volatile memory temporarily and a second recording mode for recording the image data in said volatile memory; and
a display for displaying the maintainable time when the second recording mode is selected by said recording mode selector. - View Dependent Claims (12, 17)
