Clock time information displayable together with a corresponding image upon image playback display is recorded in a header field of an image file as EXIF data, and clock time information specific to a digital camera is recorded in a header field of the image file difference from the header field for the clock time information recorded as the EXIF data. Since the camera-specific time information is recorded in addition to the display time information, even if pictures are taken with a digital camera abroad where there is a difference in time after the display clock time is corrected or changed to the local time, images of the pictures can be playback-displayed in order of actual shooting based on the camera-specific time information.

In an electronic camera system, a camera body includes a card slot for receiving a memory card M, a card slot for receiving an HDD pack H, and a battery chamber for receiving a battery B. An expansion unit includes a grip portion for receiving a battery back having a power supply capacity larger than that of the battery B, a detection switch for detecting the attached state of the expansion unit to the electronic camera, and an LCD panel for displaying a predetermined alarm message when the HDD pack H is inserted into the card slot, and the detection switch detects that the expansion unit is not attached to the electronic camera.

A heat sublimable printer in which the present invention is implemented consists mainly of a battery, a thermal head, and a control circuit. The battery offers a rated voltage of 14.8 V and is freely attached or detached to or from a housing of the heat sublimatic printer. The thermal head is incorporated in the housing, provided with a plurality of heating elements whose resistances range from 2800 &OHgr; to 3160 &OHgr;, and used to print an image on paper according to image data. The control circuit that is incorporated in the housing applies a supply voltage developed from the battery to the thermal head without boosting it, and controls the timing of electrically conducting the thermal head.
