The present invention relates to caption removal of a video device, and more particularly, to a caption removal method of a video device suitable for removing a caption according to a user's intention.

In general, when learning a foreign language using a VCR (Video Casette Recorder) with a subtitle function, the subtitle is displayed on the screen to help the user's learning efficiency.

However, in the related art, when a user who is fluent in a foreign language wants to watch a subtitle while watching a foreign language, the subtitle is rather annoying to the user, thereby degrading foreign language learning efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a method for removing subtitles of a video device capable of removing subtitles according to a user's intention.

In order to achieve the above object, the present invention provides a key input unit for a user to operate a key, an image detection unit for detecting whether a video tape is played, and an image detection unit and a key input unit. And a control unit (eg, a microcomputer) for performing an OSD function according to a signal, and an image output unit connected to the control unit to display a corresponding image including an OSD function.

Hereinafter, referring to the embodiment of the present invention, as shown in FIG. 1, a key input unit 1 through which a user inputs a key, an image detection unit 2 for detecting reproduction of a video tape, and the image detection unit 2 and a key A control unit 3 for receiving an input signal from the input unit 1 to perform an OSD function, an image processor 4, a mixer 5, and a switching circuit 6 for receiving a signal from the control unit 3 to display a corresponding image. And an image output unit 8 made of a display 7.

According to the present invention configured as described above, the key input unit 1 generates a signal according to the user's intention, such as subtitle removal, that is, a user's key operation, and the image detection unit 2 detects the playback state of the video tape to reproduce the video tape. Generate a detection signal.

In addition, the control unit 3 receives the signals from the image detector 2 and the key input unit 1 and generates color signals (Red, Green, Blue, Signal) according to the image as OSD signals during videotape playback, and removes subtitles. If desired, an OSD blank signal for erasing the subtitle is generated instead of the color signal.

Subsequently, the image processor 4 of the image output unit 8 generates an image signal of each color signal including subtitles by video tape reproduction, and the mixer 5 mixes the signals of the image processor 4 and the control unit 3. do.

Next, the switching circuit 6 receives the signal of the mixer 5 and applies each color signal to each cathode (not shown) of the display 7 so that the corresponding image appears on the screen.

And, referring to the algorithm of the control unit 3 with reference to FIG. 2, when the OSD blank is specified upward because the subtitle is in the upper part of the screen after entering the subtitle erasing mode, the upper part of the screen is formed by forming the OSD blank in the upper part of the screen. Subtitles are removed (FIG. 2 S1 to S4). That is, the OSD blank is formed in the subtitle area according to the subtitle position to remove the subtitle.

Subsequently, if it is determined in the step S1 that the subtitles are not in the subtitle deletion mode, the subtitles are displayed as they are by normal playback (S5 and S6).

next; In step S3, when the OSD blank is determined as the subtitle is at the bottom of the screen, an OSD blank is formed at the bottom of the screen to remove the subtitle at the bottom of the screen (S7).

As described above, the present invention can install the algorithm in the control unit 3 so that the subtitle can be removed according to the user's intention, and thus the subtitle function of the video device can be used more conveniently.

Claims (3)

Judging whether the subtitle deletion mode is applied (S1); when the subtitle deletion mode is entered in step S1, determining the OSD blank position after entering the subtitle deletion mode (S2, S3); and in the step S3, If it is determined that the subtitle is at the top of the screen, forming a OSD blank on the top of the screen to remove the subtitle and removing the subtitle of the video device in step (S4). The method of claim 1, further comprising the step (S5, S6) of normal playback if the subtitle deletion mode is not in the step (S1). The method of claim 1, wherein if it is determined in step S3 that the subtitles are located at the bottom of the screen, a method of removing subtitles of the video apparatus includes forming a QSD blank at the bottom of the screen to remove the subtitles. .
