Abstract: 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.

Abstract: Upon copying or moving an image file assigned a file name and containing image data and at least either a shooting date and time related to the image data or exposure related information at the time of shooting to record the image file onto recording means, the file name of the image file to be to be recorded at present is compared with file names of image files already recorded on the recording means. As a result of comparison, when there is no image file having the same file name, the image file to be recorded at present is recorded, or when there is an image file having the same file name, two image files are compared in terms of at least either the shooting date and time or the exposure related information at the time of shooting.

Abstract: A camera comprises a beam splitter configured to divide an incident light from a subject through a photographing lens, an eyepiece lens configured to observe the incident light divided by the beam splitter with a viewfinder, a relay lens provided between the beam splitter and the eyepiece lens, and a shutter provided in a vicinity of the relay lens and configured to cut a reverse-incident light from the eyepiece lens.

Abstract: 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.

Abstract: 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.
