APPARATUSES FOR AND METHODS OF PREVIEWING A MOVING PICTURE FILE IN DIGITAL IMAGE PROCESSOR

1 . An apparatus for previewing a moving picture file in a digital image processor, the apparatus comprising a digital signal processing unit configured to:

extract frames at predetermined time intervals from a selected moving picture file; and

sequential display the extracted frames.

2 . The apparatus of claim 1 , wherein the digital signal processing unit is further configured to:

respond to receiving a reproduction signal, by reproducing the moving picture file.

3 . The apparatus of claim 2 , wherein the digital signal processing unit comprises:

a frame extracting unit configured to extract frames at predetermined time intervals from the moving picture file;

a slideshow executing unit configured to reproduce the extracted frames as a slideshow; and

a control unit configured to:

respond to receiving a frame extraction interval signal by controlling the frame extracting unit and the slideshow executing unit to display a slideshow of the selected moving picture file; and

respond to receiving a reproduction signal by reproducing the selected moving picture file.

4 . An apparatus for previewing a moving picture file in a digital image processor, the apparatus comprising a digital signal processing unit configured to:

respond to the selection of a moving picture file in a thumbnail screen on which moving picture files and still image files are displayed, by extracting frames at predetermined time intervals from the selected moving picture file and shrinking the extracted frames to a thumbnail size, and sequentially displaying the shrunken frames.

5 . The apparatus of claim 4 , wherein the digital signal processing unit is further configured to: expand the thumbnail screen to a full-sized screen, and sequentially display the extracted frames on the full-sized screen, and respond to a reproduction signal by reproducing the moving picture file.

6 . The apparatus of claim 4 , wherein the digital signal processing unit comprises:

a frame extracting unit configured to extract frames at predetermined time intervals from the moving picture file;

a shrinking unit configured to shrink the extracted frames to a thumbnail size;

a slideshow executing unit configured to reproduce the shrunken frames as a slideshow and configured to expand the slideshow into a full-screen slideshow; and

a control unit configured to:

respond to receiving a frame extraction interval signal, by controlling the frames extraction unit, the shrinking unit, and the slideshow executing unit to display a slideshow of the moving picture file;

respond to a receiving an expand signal by controlling the slideshow executing unit to display a full-screen slideshow of the moving picture file; and

respond to receiving a reproduction signal by reproducing the moving picture file.

7 . The apparatus of claim 4 , wherein the digital signal processing unit comprises:

a frame extracting unit configured to extract frames at predetermined time intervals from the moving picture file;

a slideshow executing unit configured to reproduce the extracted frames as a slideshow;

a shrinking unit configured to shrink the frames reproduced as the slideshow to a thumbnail size; and

a control unit configured to:

respond to a frame extraction interval signal, by controlling the frame extracting unit and the slideshow executing unit to display a slideshow of the moving picture file on a full-sized screen;

respond to receiving a reproduction signal by reproducing the moving picture file; and

respond to a shrink signal, by controlling the shrinking unit, and the slideshow executing unit to display a thumbnail size slideshow of the moving picture file.

8 . A method of previewing a moving picture file in a digital image processor, the method comprising:

extracting frames at predetermined time intervals from a selected moving picture file; and

sequentially displaying the extracted frames.

9 . The method of claim 8 , further comprising responsive to a reproduction signal, reproducing the moving picture file.

10 . The method of claim 8 , wherein the sequential displaying of the extracted frames further comprises reproducing the extracted frames as a slideshow.

11 . A method of previewing a moving picture file in a digital image processor, the method comprising:

responsive to the selection of a moving picture file in a thumbnail screen on which moving picture files and still image files are displayed, extracting frames of the moving picture file at predetermined time intervals,

shrinking the extracted frames to a thumbnail size, and

sequentially displaying the shrunken frames.

12 . The method of claim 11 , further comprising expanding the thumbnail size to a full-sized screen and responsive to receiving a reproduction signal, reproducing the moving picture file.

13 . The method of claim 11 , wherein the sequential displaying of the shrunken frames further comprises reproducing the shrunken frames as a slideshow.

14 . A method of previewing a moving picture file in a digital image processor, the method comprising:

responsive to the selection of a moving picture file in a thumbnail screen on which moving picture files and still image files are displayed, extracting frames of the moving picture file at predetermined time intervals;

reproducing the extracted frames as a slideshow; and

shrinking the reproduced frames as the slideshow and sequentially displaying the shrunken frames.

15 . The method of claim 14 , further comprising expanding the thumbnail screen to a full-sized screen and responsive to a reproduction signal, reproducing the moving picture file.
