Digital camera

1. A digital camera comprising:

an image-capturing device that creates a cleaning image which is used for pinpointing dust particles attached to an image sensor;

an image processor that creates an inverted cleaning image so that the top and bottom of a subject image provided on the image sensor match the top and bottom of a subject image included in the cleaning image; and

a display that displays the inverted cleaning image.

2. The digital camera according to claim 1 , wherein said image processor creates the inverted cleaning image so that the right and left of an image formed on the image sensor match the right and left of the cleaning image.

3. The digital camera according to claim 2 , wherein said display is provided on the back of said digital camera, and displays the inverted cleaning image so that the top, bottom, right, and left of an image formed on the image sensor match the top, bottom, right, and left of the inverted cleaning image.

4. The digital camera according to claim 1 , further comprising an image-composing device that creates a combined cleaning image by combining the cleaning image and an orientation image which is used for discriminating the top, bottom, right, and left of the cleaning image, wherein said image processor creates the inverted cleaning image so that the top and bottom of a subject image provided on the image sensor match the top and bottom of a subject image included in the combined cleaning image, and wherein said display displays the inverted cleaning image.

5. The digital camera according to claim 1 , further comprising a memory that stores the inverted cleaning image and/or the combined cleaning image.

6. The digital camera according to claim 1 , further comprising a file-name determining device that assigns the cleaning image a file name indicating that the named file is an image used for cleaning.

7. The digital camera according to claim 1 , further comprising a file-information writing device that writes file information indicating the status of cleaning image into the cleaning image file.

8. A single-lens reflex camera comprising:

an image-capturing device that creates a cleaning image which is used for pinpointing dust particles attached to an image sensor;

an image processor that creates an inverted cleaning image so that the top and bottom of a subject image provided on the image sensor match the top and bottom of a subject image included in the cleaning image;

a display that displays the inverted cleaning image; and

an image-composing device that creates a combined cleaning image by combining the cleaning image and a lens mount image which illustrates a lens mount as seen from a lens of said single-lens reflex camera and is used for discriminating the top, bottom, right, and left of the cleaning image;

said image processor creating the inverted cleaning image so that the top and bottom of a subject image provided on the image sensor match the top and bottom of a subject image included in the combined cleaning image;

said display displaying the inverted cleaning image.

9. A digital camera system comprising:

a digital camera that comprises an image-capturing device that takes a cleaning image which is used for pinpointing dust particles attached to an image sensor, and an image processor that creates an inverted cleaning image so that the top and bottom of a subject image provided on the image sensor match the top and bottom of a subject image included in the cleaning image;

an external receiver device that is provided on the exterior of said digital camera, and that receives the inverted cleaning image from said digital camera; and

an external display that is provided on the exterior of said digital camera, and displays the inverted cleaning image.
