an acquisition module that acquires an image file from a storage module;

a determination module

that determines whether the acquired image file belongs to an image file group including two or more image files, each of the two or more image files being an original image file and a generated image file generated from the original image file,

that determines whether the acquired image file is a generated single image file which does not have a corresponding original image file stored in the storage module, and

that determines whether the acquired image file is an original single image file which does not have a corresponding generated image file stored in the storage module; and

a control module

that displays on the display unit an image corresponding to only one of the image files belonging to the image file group in a visually recognizable manner when it is determined by the determination module that the acquired image file belongs to the image file group,

that displays on the display unit an image corresponding to the acquired image file as an original single image file in a visually recognizable manner when it is determined by the determination module that the acquired image file is an original single image file, and

that displays on the display unit an image corresponding to the acquired image file as a generated single image file in a visually recognizable manner when it is determined by the determination module that the acquired image file is a generated single image file,

wherein the control module displays on the display unit the image corresponding to only one of the image files belonging to the image file group with an indicator, the image corresponding to the acquired image file as an original single image file with the indicator, and the image corresponding to the acquired image file as a generated single image file without the indicator.

2. The image display controlling device according to claim 1 , wherein the control module displays on the display unit an image of an image file determined by the determination module as belonging to the image file group and an image of a single image file determined by the determination module as not belonging to the image file group, in mutually different modes.

3. The image display controlling device according to claim 2 , wherein, in displaying on the display unit an image of the image file group and an image not belonging to the image file group in mutually different modes, the control module displays on the display unit an image of an image file belonging to the image file group, an image of an original image file not included in the image file group, and an image of a generated image file not belonging to the image file group in mutually distinguishable modes using different colors.

4. The image display controlling device according to claim 1 , wherein the determination module determines whether the acquired image file belongs to an image file group including a RAW file and a JPEG file, the RAW file being a pre-development, uncompressed or lossless-compressed file that serves as the original image file, and the JPEG file being a post-development lossy-compressed file that serves as the generated image file.

5. The image display controlling device according to claim 1 , wherein, in displaying on the display unit information regarding the image file group in the visually recognizable manner, the control module displays on the display unit at least one of information regarding a device used for imaging of the original image file included in the image file group, information regarding a device used for imaging of the generated image file, and information regarding a device used for generation of the generated image file, the information being represented by text, graphics, or symbols.

6. The image display controlling device according to claim 1 , wherein, in displaying on the display unit information regarding the image file group in the visually recognizable manner, the control module displays on the display unit information regarding which of the image files the displayed image is based on among the image files belonging to the image file group.

7. The image display controlling device according to claim 1 , further comprising an instruction acquisition module that acquires from the user an instruction for starting selection of an image file on which a predefined processing is to be executed, wherein the determination module checks whether the image file stored in the storage module belongs to the image file group after the instruction acquisition module has obtained the instruction for starting selection of an image file.

8. The image display controlling device according to claim 7 , wherein the control module displays information that allows the user to select one of deletion of an image file, copying of an image file, moving of an image file, and printing of an image file, and generation of a generated image file as the predefined processing.

9. An imaging device comprising:

an imaging module capable of capturing an image of an object;

an image-file creating module that creates an image file from information of the image captured by the imaging module and that stores the image file in a storage module; and

the image display controlling device according to claim 1 .

10. The image display controlling device according to claim 1 , wherein:

the indicator comprises a color of a frame;

the control module displays on the display unit the image corresponding to only one of the image files belonging to the image file group with a first frame having a first color;

the control module displays on the display unit the image corresponding to the acquired image file as an original single image file with a second frame having the first color; and

the control module displays on the display unit the image corresponding to the acquired image file as a generated single image file with a third frame having a second color different from the first color.

11. An image display method using a display unit capable of displaying an image and a storage module capable of storing an image file, comprising the steps of:

(a) determining whether an acquired image file belongs to an image file group including two or more image files, each of the two or more image files being an original image file and a generated image file generated from the original image file;

(b) determining whether the acquired image is a generated single image file which does not have a corresponding an original image file stored in the storage module;

(c) determining whether the acquired image file is an original single image file which does not have a corresponding generated image file stored in the storage module;

(d) displaying on the display unit an image corresponding to only one of the image files belonging to the image file group in a visually recognizable manner when it is determined by the step (a) that the acquired image file belongs to the image file group;

(e) displaying on the display unit an image corresponding to the acquired image file as an original single image file in a visually recognizable manner when it is determined by the step (a) that the acquired image file is an original single image file; and

(f) displaying on the display unit an image corresponding to the acquired image file as a generated single image file in a visually recognizable manner when it is determined by the step (a) that the acquired image file is a generated single image file,

wherein the image corresponding to only one of the image files belonging to the image file group is displayed with an indicator, the image corresponding to the acquired image file as an original single image file is displayed with the indicator, and the image corresponding to the acquired image file as a generated single image file is displayed without the indicator.

12. The image display controlling device according to claim 10 , wherein:

the indicator comprises a color of a frame,

the image corresponding to only one of the image files belonging to the image file group is displayed with a first frame having a first color,

the image corresponding to the acquired image file as an original single image file is displayed with a second frame having the first color, and

the image corresponding to the acquired image file as a generated single image file is displayed with a third frame having a second color different from the first color.
