First, when a function button of, for example, the operation unit 200 (see Fig. 1) is pressed by the user's operation, the CPU 100 processes the signal to enter the automatic moving picture reproducing mode, .

The moving picture file classification unit 103 classifies only moving picture files among the photographed image files. Generally, in the playback mode of the digital image processing apparatus, the captured moving image file and the still image file are mixed and not separated. FIG. 3 shows a state in which a moving picture file and a still picture file are mixed on the display unit in the playback mode. Here, the facial expressions of the face image represent the first frames of each video file, and the graphic representations of the triangle represent the images of the still image. The moving picture file classification unit 103 classifies only moving picture files among the mixed moving picture and still picture files as shown in FIG.

As a method of separately classifying only video files, for example, a method of automatically searching only video files whose extension ends in .Avi among the files in which video and still images are mixed, as shown in FIG. 3, may be used. Meanwhile, only the video files desired by the user among the files in which the moving image and the still image are mixed can be separately classified. For example, a passive method may be used in which a user moves a moving picture desired to be reproduced by using a direction key, and then presses a selection button for selecting the screen. In the latter case, when the capacity of the selected moving image file is large, movement of the moving image file may not be smooth as will be described later. Therefore, the number of selected moving image files may be limited.

The moving picture file movement control unit 105 moves the moving picture files classified as described above to the generated virtual folder. At this time, when a large number of moving picture files to be moved or a large time is required, it is possible to display on the screen that the moving picture files are moving to the virtual folder for the convenience of the user. 4 shows an example of displaying on the screen a message "Processing .." on the screen to indicate that the classified moving picture files are being moved to the created virtual folder.

In the meantime, according to the above description, it is described that the virtual folder is generated first and then the moving picture files are moved to the generated virtual folder. However, the moving picture files are classified first and then the virtual folder is generated It is also possible to move the moving picture files classified into the virtual folders.

As described above, when the moving picture files classified automatically or by the user's selection are moved to the virtual folder, the automatic moving picture playback start event occurs and the moving picture file automatic playback control unit 107 is stored in the virtual folder Automatically play the video files. When the moving picture files are automatically reproduced, the moving picture files stored in the virtual folder may be sequentially reproduced in the DCF number order, or the moving picture files may be randomly reproduced in random order.

FIG. 5 is a conceptual diagram illustrating an example in which moving images are automatically reproduced according to the flow of time. Here, the description will be made on the basis of the state in which three moving pictures among the mixed files shown in FIG. 3 are moved to the virtual folder. First, referring to FIG. 5A, the moving picture files stored in the virtual folder are displayed on the display unit 90 as a thumbnail screen. Next, as shown in FIG. 5B, the first moving picture file is reproduced and the second and third moving picture files are sequentially and automatically reproduced in order as shown in FIGS. 5C and 5D. After the automatic reproduction of the moving image files is completed, the moving image files are displayed on the display unit 90 as a thumbnail screen as shown in FIG. 5 (e).

6 is a conceptual diagram showing another example in which moving picture files are automatically reproduced according to the flow of time. 6 (a), 6 (c) and 6 (e), the moving picture files stored in the virtual folder are displayed on the display unit 90 as a thumbnail screen, 5 is different from FIG. 5 in that a thumbnail screen informs in advance which moving picture screen is to be reproduced next. That is, in the case of FIG. 5, first, all the video files are displayed on the thumbnail screen at one time and then the video files are continuously played. In the case of FIG. 6, the first frame of the video file to be played next is displayed on the thumbnail screen The video file is reproduced, the first frame of the video file to be reproduced next is displayed on the thumbnail screen, and the video file is reproduced. Therefore, in the case of FIG. 6, a convenient interface is provided by providing the user with dictionary information about what is the next moving picture file to be played back.

As described above, the digital image processing apparatus according to the present embodiment selects and categorizes moving image files among the photographed image files, moves the moving image files to a virtual folder, and automatically reproduces the moving image files stored in the virtual folder, Interest can be provided. Of course, this embodiment discloses a digital image processing apparatus that selects only a moving image file among the mixed image files and automatically reproduces the moving image file. However, if the average knowledge in this technical field is known, It is possible to devise a digital photographing apparatus that automatically reproduces images.

7 is a block diagram for executing a digital image processing apparatus according to another embodiment of the present invention. The components shown in Fig. 7 may be a part of the CPU 100 shown in Fig. 1 or an independent component that is not a part of the CPU 100.
