Abstract

The digital camera photographs a moving image to record moving image data in an internal or an external memory. Plural frame images as index images are extracted from the moving image. A display area in an LCD is divided into plural index frames for displaying the index images. The number of the index frames is determined in accordance with the number of the index images, so that all of the index images are displayed at the same time. The moving image is reproduced from the scene corresponding to the selected index image.

Claims

1. A digital camera for reproducing a moving image of a predetermined length having a plurality of frame images, the digital camera comprising:

a moving image processing device that extracts individual frame images as index images from the moving image at a regular interval;

a first display device that displays the index images in a divided display area, the first display device changing a number by which to divide the display area in accordance with a total number of the index images extracted from the moving image of a predetermined length,

wherein if said total number of index images extracted from the moving image of a predetermined length exceeds a maximum, said regular interval is elongated such that said total number of index images extracted from the moving image of a predetermined length is equal to or less than said maximum; and

a controller that starts reproduction of the moving image from the scene corresponding to a selected index image.

2. A digital camera according to claim 1, wherein the, first display device displays all index images at the same time.

3. A digital camera according to claim 1, wherein the first display device displays the index images and the moving image at the same time.

4. A digital camera according to claim 1, further comprising a second display device that displays the moving image.

5. A digital camera according to claim 1, further comprising a photography device that captures a subject image continuously to obtain the moving image.

6. A digital camera according to claim 1 wherein said total number of index images extracted from the moving image of a predetermined length is not less than a minimum.

7. A method, used in a digital camera, for reproducing a moving image of a predetermined length with a plurality, of frame images, the method comprising the steps of:

extracting individual frame images as index images from the moving image at a regular interval;

displaying the index images in a divided display area of a first display device, the first display device changing a number by which to divide the display area in accordance with a total number of the index images extracted from the moving image of a predetermined length,

wherein if said total number of index images extracted from the moving image of a predetermined length exceeds a maximum, said regular interval is elongated such that said total number of index images extracted from the moving image of a predetermined length is equal to or less than said maximum; and

starting reproduction of the moving image from the scene corresponding to a selected index image.

8. A method according to claim 7, wherein the first display device displays all index images at the same time.

9. A method according to claim 7, wherein the first display device displays the index images and the moving image at the same time.

10. A method according to claim 7, wherein the moving image is reproduced in a second display device.

11. A method according to claim 7 wherein said total number of index images extracted from the moving image of a predetermined length is not less than a minimum.
