Make it available as a thumbnail when editing.

However, according to the related art, when a thumbnail of a moving image title is to be changed, it is troublesome to directly designate a specific still image to be used as a thumbnail after checking a list of all still images stored in the digital recorder.

In particular, in the case of a series moving picture, even if individual moving picture titles recorded at different times are required to share the thumbnails, it is necessary to improve the discriminant identification of the titles by the thumbnails. There was a troublesome problem.

The present invention has been proposed to solve such a conventional problem, and the degree of agreement of recording information in a digital recorder which enables to use a thumbnail of an image of a disc being played back or still, or a moving image or still image input from the outside as a thumbnail when editing a moving image title It is an object of the present invention to provide a thumbnail recording method of a digital recorder that automatically matches thumbnails of titles according to the present invention.

In order to achieve the above object, a method for generating a thumbnail of a digital recorder according to the present invention includes a single thumbnail for a plurality of recordings in a digital recorder which generates a still image captured by a user in a recording list of a plurality of recordings. A method of sharing video, comprising: determining whether there is an automatic matching command for a thumbnail image of a specific recording for editing a recording list, and recording recording information of the recording being edited and preset thumbnail images according to the automatic matching command Comparing the information to calculate the matching degree of the recording information, and if the matching information is calculated, sorting the thumbnail images according to the matching degree order to display a plurality of thumbnail images as a list, and editing among the sorted thumbnail image list The thumbnail of the recording or one of the recording information And setting the thumbnail image of the highest degree to the thumbnail of the recording being edited.

There may be a plurality of embodiments of the present invention, hereinafter with reference to the accompanying drawings will be described in detail a preferred embodiment. Through this embodiment will be able to better understand the objects, features and advantages of the present invention.

As shown in the block diagram of FIG. 1, the digital recorder capable of performing the thumbnail generation method according to the present invention includes the storage 210, the recording / reproducing unit 220, the microcomputer 230, and the OSD generating unit 240. , A flash memory 250, a still image extractor 260, and a key input unit 270.

The storage 210 may be a hard disk in which various programs of digital video and audio data are recorded and stored, and the recording / reproducing unit 220 is suitable for recording data input from the outside under the control of the operation of the microcomputer 230. Signal processing is performed on the data to record on the hard disk or to perform a series of data recording and reproducing operations of reading and reproducing the data recorded on the hard disk.

The microcomputer 230 controls the operation of the OSD generator 240 when a recording list is displayed from the user, and the OSD generator 240 outputs a recording list of a plurality of programs recorded on the hard disk. do. At this time, the recording list is outputted including, for example, a thumbnail image representing each program, and recording information such as a program name, a recording date, and time information.

In addition, the microcomputer 230 plays a key input unit 270 while playing multimedia data such as a moving image stored in the storage 210 through the recording / reproducing unit 220 or recording / reproducing multimedia data input from the outside. When the capture command is input through the controller, the process of storing the still image corresponding to the moment when the capture command is input to the flash memory 250 is controlled. When a "recording list" is requested according to a user's request, the OSD generating unit 240 is controlled to display a plurality of recording lists including thumbnail images in a pop-up window and to select an arbitrary recording list from among a plurality of recording lists. To be larger. Subsequently, the cursor moves by a user's operation to be placed on an arbitrary recording list, and if there is a command to edit the recording list, one of the still images stored in the flash memory 250 is displayed for the thumbnail image of the recording list where the cursor is located. Select to control the setting process. Then, the microcomputer 230 additionally records the selected still image on, for example, a DVD-RW disc, and updates thumbnail position information of the corresponding title by using the position information of the recorded still image.

In particular, the microcomputer 230 compares recording information such as program name, recording date, and time information included in the recording list when a thumbnail auto matching command is input through the key input unit 270 in the menu screen for editing the recording list. To control the process of displaying a plurality of thumbnail images in the list according to the order of matching of the recording information, and set any thumbnail image with the highest match as the thumbnail of the title being edited or the specific thumbnail image selected by the user for the title being edited. Set to thumbnail. Then, the microcomputer 230 updates thumbnail position information of the corresponding title by using the automatic matching or position information on the selected thumbnail image.

The still image extracting unit 260 extracts a scene or a frame at a predetermined moment through a predetermined algorithm under the control of the microcomputer 230 according to a user's key input command and selects the still image. The still image selected as the thumbnail image is stored in title information of the corresponding program.

The key input unit 270 inputs a command for capturing a specific image of the reproduced multimedia data, or inputs a command for editing a thumbnail image in the recording list. And, the still image for thumbnails stored in the flash memory 250 has a limit of the number that can be stored because of the capacity of the flash memory 250. Accordingly, the key input unit 270 includes a button for inputting a command for deleting some of the still images for thumbnails stored in the flash memory 250 as required by the user.

Referring to FIGS. 1 and 2, the process of generating a thumbnail according to the present invention performed by the digital recorder configured as described above is used to edit an image of a disc being played back or a still image, or a moving image or still image input from an external source. Since the process of replacing a still image with a thumbnail image of a specific title after storing for use is described in Korean Patent Laid-Open No. 10-2005-0043354, the description thereof will be omitted below.

First, when the user requests the recording list by operating the key input unit 270 in the standby mode (S301) in which the still images previously stored in the flash memory 250 are designated as thumbnails of the moving image title, the microcomputer 230 receives a recording list. The OSD generation unit 240 is controlled to display a plurality of recording lists including thumbnail images for each program stored in the storage 210 as a popup window (S305).

The user moves the cursor by a key input operation through the key input unit 270 to place the cursor on the recording list, that is, the moving image title, to be edited, and inputs an editing command (S307).

When the recording list editing command is input from the key input unit 270, the microcomputer 230 may display a menu for editing the recording list through a pop-up window, for example, “load capture image”, “change list title”, “thumbnail auto matching”, or the like. The recording list editing menu is displayed (S309).

At this time, when the user selects the "Thumbnail Auto Match" menu from the recording list editing menu (S311), recording information such as the program name, recording date and time information of the moving image title being edited, and recording of the thumbnail images stored in the flash memory 250 is performed. The degree of agreement of the recorded information is calculated by comparing the information.

When the matching degree of the recording information for all the thumbnail images is calculated, after sorting the thumbnail images according to the matching degree order, a plurality of preset thumbnail images are displayed as a list (S313).

The user moves the cursor by a key input operation through the key input unit 270 to place the cursor on a thumbnail to be shared as a thumbnail of the moving image title being edited (S315).

Then, the microcomputer 230 sets the specific thumbnail image selected by the user as the thumbnail of the moving image title being edited, and updates thumbnail position information of the corresponding title using the position information of the selected thumbnail image (S317).

In addition, when a thumbnail selection command is not input even after a predetermined time has elapsed since the thumbnail image list is displayed in step S315, the microcomputer 230 sets an arbitrary thumbnail image having the highest agreement with the recording information as the thumbnail of the title being edited. To update the thumbnail location information.

It has been described so far limited to one embodiment of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art. Such modified embodiments should be construed as naturally included in the technical spirit described in the claims of the present invention.

As described above, according to the present invention, a thumbnail of a title according to the degree of agreement of recording information in a digital recorder can be used as a thumbnail when a moving picture title is edited or an image of a disc being played back or still, or a moving picture or still image input from the outside is automatically generated. By matching with, the convenience of not having to directly specify a specific still image is provided when sharing thumbnail images of different moving image titles.

In particular, in the case of a series moving picture, even if individual moving picture titles recorded at different times, it is necessary to share the thumbnails to improve the identification of the titles by the thumbnails. In this case, the still image designation process does not need to be repeated many times. It works.
