Claim:
A digital camera, comprising: a photographing device to photograph an object and to output image signals of the photographed object; a memory section in which a particular removable electronic memory selected from a plurality of removable electronic memories is detachably loaded, to store the image signals; a power source to supply electric power to the photographing device and the removable memory; an operation detecting device to detect an ON operation of the power source and an OFF operation of the power source; a control section to control the particular removable electronic memory to store the image signals based on memory control information including file allocation data and to generate the memory control information in accordance with a file allocation condition of the particular removable electronic memory loaded in the memory section; and a memory to store the generated memory control information in a memory control information storing area; wherein immediately after an OFF operation is detected, the memory memorizes the memory control information and retains, during the OFF condition, the memory control information corresponding to the particular removable electronic memory loaded in the memory section at the time the OFF operation is detected, and when an ON operation is detected after an OFF operation, the control section checks the memory control information and, when the memory control information generated after the ON operation is different from that stored in the memory immediately after the OFF operation, the control section conducts an automatic renewal operation for the memory control information storing area of the memory based on the memory control information generated after the ON operation, and controls said removable electronic memory based on the memory control information stored in the memory control information storing area as a result of the automatic renewal operation, and when the memory control information generated after the ON operation is the same as that stored in the memory after the OFF operation, the control section controls the removable electronic memory based on the memory control information stored immediately after the OFF operation without conducting the automatic renewal operation.
