Description

Selective Playback Method of Optical Disc Playback Device

The present invention relates to a method for conveniently selecting and playing a desired image through an optical disc reproducing apparatus.

Recently, various devices such as LDP and DVDP have been widely used in order to enjoy a movie or music video through an optical disc reproducing apparatus. Such optical disc reproducing apparatus generally plays an optical disc to process image signals generated from the optical disc reproducing apparatus. The still image and the moving image are output on a predetermined screen.

On the other hand, when there is a specific video that is to be viewed on the screen, and then wants to watch again, when the user memorizes the time value of the location and inputs it to the optical disk reproducing apparatus, it searches for it and plays the desired specific video. It was.

FIG. 1 is a control flowchart illustrating a video selective playback method of the conventional optical disc playback apparatus. Referring to this, the conventional video selective playback method will be described in detail as follows.

As shown in the figure, it is determined whether a playback key is input, and when a playback key is input, a predetermined video is played on the screen (101 to 102).

In this case, by playing the predetermined video and displaying the time value according to the position of the currently playing video, the user can store the time value corresponding to the current video when there is a desired video (103).

Thereafter, it is determined whether a time value desired for playback has been input (104). If the time value is not input, the current image reproduction is continued (102), and if the time value is input, the image corresponding to the time value from the optical disc. Search for the position of and play it (105).

Therefore, when the user stores the position of a specific image which he / she wants to see again as a corresponding time value, for example, several minutes and seconds, and inputs it to the optical disc reproducing apparatus through a key input or the like, the optical disc reproducing apparatus is set to this time value. By retrieving the position of a specific image per line, the user can reproduce the desired image.

However, the conventional method of selecting and reproducing an image of the conventional optical disc reproducing apparatus has a problem in that the operation is very inconvenient because the user must memorize the time value and play the desired image by key input through manual operation.

In addition, when reproducing a plurality of specific images, the user has to store a plurality of time values corresponding to each of them and input them individually, thereby causing another problem such that the exact location is not retrieved according to the difference in the user's memory.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for selecting and reproducing an image of an optical disc reproducing apparatus for displaying and reproducing a specific specific image desired by a user through the optical disc reproducing apparatus.

In order to achieve the above object, the present invention provides a first process of reproducing an image on a recording medium and determining an input of an image storage key when a playback key is input, and storing an image currently being reproduced when the image storage key is input in a first process. A second process of storing the positional information of the optical disc according to the image as a time value, and an image stored in the second process when the specific image selection key is input and displaying the image stored at the time of inputting the playback start key. And a third process of performing reproduction from the position.

Hereinafter, an embodiment of an image selective reproduction method of an optical disc reproducing apparatus to which the present invention is applied will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of an optical disc reproducing apparatus for explaining the present invention, in which a key input unit 10 which receives a command of various functions from a user through a key input and controls each of the keys according to the input of the key input unit 10. FIG. A microcomputer 20 for outputting a signal, an image reproducing unit 30 for reproducing an optical disc with a control signal of the microcomputer 20, and an image reproducing unit 30 for reproducing the control signal of the microcomputer 20; An image storage unit 50 for storing an image and an image reproduced by the image reproducing unit 30 on the screen according to a control signal input from the microcomputer 20 or an image stored in the image storage unit 50. It consists of an image display unit 40 for displaying on the screen.

3 is a control flowchart showing an embodiment of an image selective reproduction method of the optical disc reproducing apparatus of the present invention, and FIG. 4 is a control flowchart showing another embodiment of the image selective reproduction method of the optical disc reproducing apparatus of the present invention.

First, as an embodiment of the image selective reproducing method of the optical disc reproducing apparatus of the present invention configured as described above with reference to FIG. 3, the microcomputer 20 determines whether a reproducing key is input through the key input unit 10 to reproduce the reproducing method. When a key is input, a control signal is applied to the image reproducing unit 30 to play a predetermined image from an optical disc as a recording medium, and also initialize the variable 'CN' and the variable 'VD' to zero values, and then press the key. A first process of determining the input of the image storage key from the input unit 10 is performed (101 to 104).

When the image storage key is input in the first process, the value of the variable 'CN' is increased by 1 and the current image is stored at the position of the image storage unit 50 corresponding to the value of the variable 'CN'. A second process of storing the positional information of the optical disc as a time value is performed (105 to 106).

In this case, in the second process, when the image storage key is input in the above-described first process, it is preferable to store the image of the current one frame.

Thereafter, when the image storage key is not input in the first step, it is determined whether a specific image selection key is input, and the image selection key is input (107) and when there is an image stored in the image storage unit (108). A third process of displaying the stored image and performing reproduction from the position of the optical disc corresponding to the stored time value when the reproduction start key is input is performed.

At this time, according to an embodiment of the present invention, the value of the variable 'VD' is increased by 1 and the variable 'VD'-th stored image is displayed on the screen through the image display unit (109 to 110).

Subsequently, when the playback start key is not input, the next video is continuously displayed. When a predetermined video is selected and the playback start key is input, the video position corresponding to the time value stored in the video storage unit 50 is displayed in the video playback unit ( 30, and playback is performed at that position (111 to 113). Therefore, the images stored in the second process are sequentially displayed one by one on a screen to be selected.

Meanwhile, according to another exemplary embodiment of the present invention as shown in FIG. 4, the first and second processes are the same as described above, but the third process is to store the image stored in the second process when a specific image selection key is input. Display all on one screen to select a specific image.

That is, when all images stored in the image storage unit 50 are displayed together on the screen of the image display unit 40 (114), when a predetermined image is selected and a playback start key is input (115), the time value stored from the image reproducing unit is displayed. The image position corresponding to the P is retrieved and playback is performed at the position (116).

The present invention does not need to store the position of a specific image that a user wants to see again as a corresponding time value, so that the current image and time value can be stored in the optical disk reproducing apparatus and can be conveniently selected and played when needed. It works.
