Abstract

A camera includes a storage unit which stores an imaged image on a first recording medium as an image file, a selection unit which arbitrarily selects an image from images stored on the first recording medium, a copy unit which copies the selected image to a second recording medium, and a history file creation unit which creates a list of the copied image as a history file and stores the history file on the first recording medium.

Claims

1. An electronic camera device comprising:

a shooting unit which shoots an optical image and provides one of a still image and a moving image;

a storage unit which records the image obtained by the shooting unit on a first recording medium as an image file;

a selection unit to arbitrarily select an image from images stored on the first recording medium;

a copy unit which copies the image selected by the selection unit to a second recording medium; and

a history file creation unit which creates a list of the image copied by the copy unit as a history file and stores the history file on the first recording medium.

2. The electronic camera device according to claim 1, wherein the history file creation unit creates the history file so as to identify a copy destination of the image copied by the copy unit.

3. The electronic camera device according to claim 2, wherein the first recording medium is a hard disk drive equipped to the device, and the second recording medium is a memory card that can be removed from the device.

4. The electronic camera device according to claim 2, wherein the first recording medium is a memory card that can be removed from the device, and the second recording medium is a hard disk drive equipped to the device.

5. The electronic camera device according to claim 1, wherein when another image stored on the first recording medium is copied to the second recording medium by the copy unit, the history file creation unit updates the history file.

6. The electronic camera device according to claim 5, wherein when an image is copied by the copy unit to an external recording device connected to the electronic camera device, an update unit sends to the external recording device the history file already created and receives an updated history file from the external recording device.

7. The electronic camera device according to claim 1, wherein the history file creation unit stores on the second recording medium a second history file indicating that the image copied to the second recording medium is copied from the first recording medium.

8. The electronic camera device according to claim 7, wherein when another image stored on the first recording medium is copied to the second recording medium by the copy unit, the history file creation unit updates the second history file on the second recording medium.

9. The electronic camera device according to claim 1, further comprising:

a playback unit which plays back the image stored on the first recording medium;

a display unit which displays the image played back by the playback unit; and

a unit which determines, when the image stored on the first recording medium is displayed on the display unit, whether the image being displayed has been already copied by the copy unit with reference to the history file and displays, when the image has been already copied, on the display unit an icon indicating that the image has been already copied, together with the image being displayed.

10. The electronic camera device according to claim 1, further comprising:

a playback unit which plays back the image stored on the first recording medium;

a display unit which displays the image played back by the playback unit;

a unit which selects a candidate for deletion from the images stored on the first recording medium and displays the selected candidate on the display unit;

a unit which determines, with reference to the history file, whether an image being displayed as the candidate for deletion has been already copied by the copy unit; and

a unit that displays a warning when the candidate for deletion has not been already copied and an instruction to delete the candidate for deletion is issued.

11. A method of creating a history file in an electronic camera device, the method comprising:

storing an image obtained by shooting an optical image on a first recording medium as an image file;

arbitrarily selecting an image from images stored on the first recording medium;

copying the selected image to a second recording medium; and

creating a list of the copied image as a history file showing a copy state and storing the history file on the first recording medium.
