The video representative image setting according to the present invention may be initiated by generating a user input or a video file requesting this (S300).

The user selects an object to be designated as the video representative image from the list representing the object that can be set as the video representative image (S302). To this end, the apparatus providing the method may display a list of selectable objects through the display unit 50 and receive a user input for selecting an object to be designated as the representative image through the manipulation unit 20.

According to the present invention, the list of objects that can be set as the video representative image includes not only the video but also other video files and other image files. Accordingly, the user may set not only the frame in the video but also the frame or other image file of another video as the representative image of the video.

When a user input for selecting an object to be set as the representative image is input, it is determined whether the selected object is a video (S304).

If the object selected by the user is a movie, play the selected movie so that the user can select an arbitrary frame, and the user presses the corresponding key (24a, 24b or 24c) in the scene that the user wants to set as the representative image during movie playback. A frame to be set as an image is selected (S306). When the user presses a key, the device implementing the present invention may capture the frame and generate the file in a representative image format or store the frame number.

If the object selected by the user is an image file, the size of the image is converted into the video representative image size (S308). For example, when the image file has a resolution of 1024 * 768 and the representative image has a resolution of 160 * 120, the image file is size-converted according to the resolution of the representative image. Algorithms for size conversion have a variety of known techniques.

When the selected object is a moving picture file, a frame designated by the file or frame number of the generated representative image format is set as a temporary representative image. If the selected object is an image file, the size-converted image file is set as a temporary representative image (S310). The temporary representative image may be stored in the main memory device 30.

If the temporary representative image is set, the user inquires whether to add text to the representative image (S312). To this end, the device may provide a selection screen for inquiring whether to add the text, and may determine whether the user adds the text according to a user input input on the screen.

In addition, a keyword or the like that can represent the contents of the video can be input.

After the user inputs the text, the text is added to the temporary representative image to generate a video representative image (S316). Various text embedding techniques can be used to add text to an image.

Next, the temporary representative image is set as the video representative image (S318). If the user wants to add text, the temporary representative image to which the text is added is set as the video representative image. If the user does not want to add the text, the temporary representative image is immediately set as the video representative image without the process of receiving and adding the text (S314, S316). In this case, the temporary representative image may be displayed and a process of confirming to the user as to whether it is set as the video representative image may be performed.

According to the first embodiment of the present invention, the temporary representative image is added as the first frame of the video file. When the device sets the first frame as the representative image for all the video files, when the temporary representative image is added to the first frame, the temporary representative image is eventually set as the representative image.

According to the second embodiment of the present invention, the temporary representative image is stored in the space for the representative image in the moving image file. This may be a thumbnail storage space of a video.

In this method, the representative image setting is completed and ends (S320).

When the video representative image is set by adding the text input by the user, as shown in FIG. 4, the video added with the text input by the user is provided as the video representative image as shown in FIG. 4 (the video representative image of the TN2). Reference). As a result, the user can easily identify what the video file is about, and it is possible to reflect his / her request in the video representative image.
