FIG. 3 is a flowchart showing a step S301 of confirming whether the TV is on, a step S302 of watching TV if the TV is on, (S303) of judging whether to sequentially move the horizontal / vertical corner positions of the horizontal / vertical corner positions of the TV screen, and watching a normal TV screen if the judged result does not input the "key " S312), and if the input of the "key" is to move the horizontal / vertical corner position sequentially, step S304 of issuing a control command and step S304 of storing a video of one frame according to the control command S304-1), a step S305 of moving left and right horizontal positions of a screen edge according to the procedure for the stored one frame image, a step S306 of confirming the shifted left and right horizontal positions, , The right horizontal position is returned to the microcomputer 200 ( (S307-1), viewing an image of a corner portion at the identified left and right horizontal positions (S307), and displaying the vertical and horizontal vertical positions of the screen edges with respect to the one frame image stored in accordance with the procedure of the subsequent control command (S309) of confirming the shifted upper and lower vertical positions (S309); returning the confirmed upper and lower vertical positions to the microcomputer 200 (S307-1) (S310) of judging whether the horizontal / vertical position movement of the screen is to be terminated or not; a step S311 of judging whether the horizontal / vertical position movement of the screen is to be terminated; If the positional movement is to be continued, the process returns to step S304, and if it is determined that there is a "key" input and the movement of the horizontal / vertical position of the screen is to be terminated, step S312 of viewing a normal TV screen is performed.

When the user operates the key input unit 220 to select a broadcast channel to be viewed in a state in which the TV is turned on (S301) after the power is turned on, The microcomputer 200 generates a channel selection voltage corresponding thereto and applies it to the tuner 100. [ The tuner 100 tunes the broadcast signal of the broadcast channel selected by the tuning voltage generated by the microcomputer 200 to a broadcast signal received from the free space through the antenna ANT and outputs the tuned signal to the video processor 300 and the audio processor 500 As shown in Fig. The image processor 300 processes the video signal in the broadcast signal input from the tuner 100 according to the control signal of the microcomputer 200 and inputs the processed video signal to the video amplifier 320. That is, the image amplifying unit 320 amplifies the image signal to a level that can be displayed on the screen of the CRT 400, and supplies the amplified image signal to the CRT 400. As a result, The viewer views the image (S302).

The voice processor 500 processes the voice signal from the broadcast signal input from the tuner 100 and inputs the processed voice signal to the voice amplifier 520. Therefore, the audio amplifying unit 520 amplifies the audio signal processed by the audio processing unit 500 to a predetermined level, and outputs the amplified audio signal to the speakers 600 and 620 so that the viewer can listen to the audio.

During the watching of the TV, the microcomputer 200 determines whether to sequentially move the horizontal / vertical corner positions of the TV screen (S303) and moves the horizontal / vertical corner positions of the screen of the CRT 400 in the key input unit 220 The microcomputer 200 outputs a control signal to the image processor 300 so that the image of the broadcast signal processed in the image processor 300 is output to the image processor 300. [ The signal is amplified to a predetermined level via the image amplifying unit 320 and displayed on the screen of the CRT 400 so that the viewer can watch a normal image (S312).

In step S303, the microcomputer 200 determines whether to sequentially move the horizontal / vertical corner positions of the TV screen. In step S303, the microcomputer 200 determines whether the horizontal / vertical corner positions of the screen of the CRT 400 are moved When the user inputs the "key" and sequentially moves the horizontal / vertical corner positions, the microcomputer 200 transmits the one frame image storage unit 720, the horizontal position The image processor 300 firstly transmits control commands to the moving unit 712 and the vertical position moving unit 714 in order to output the image of one frame received by the image processor 300 from the tuner 100 to the one- The horizontal position shifting unit 712 shifts the left and right horizontal positions of the one-frame image stored by the control command sequentially according to the "key" input by the viewer in the microcomputer 200, (S305) and stores it, The inserting unit 716 confirms the left and right horizontal position of the screen of the moved CRT 400 in step S306 and returns the screen to the microcomputer 200 in step S307-1. When it is confirmed that the position has been moved, the image signal stored in the one frame image storage unit 320 is output to the image amplification unit 320. Thus, the image of the corner portion moved on the screen of the CRT 400 is displayed through the image amplifying unit 320 so that the viewer can accurately view the image of the left and right corner portions (S307).

Subsequently, when the left / right shifted image is displayed on the screen of the CRT 400, the vertical position shifting unit 714 shifts the control commands sequentially according to the "key" input by the viewer in the microcomputer 200 (S308), and then the position confirming unit 718 confirms the up / down vertical position of the screen of the moved CRT 400 (S309) The microcomputer 200 returns the image signal stored in the one frame image storage unit 320 to the image amplification unit 320. When the image signal is stored in the one frame image storage unit 320, (320). Thus, the image shifted up / down on the screen of the CRT 400 is displayed through the image amplification unit 320 so that the viewer can accurately view the image of the upper and lower edges (S310).

Therefore, for example, when the viewer selects left and right in selecting the horizontal / vertical corner position shift key, the viewer outputs the screen horizontally shifted to the left first and then vertically shifted downward sequentially, You can see the screen in the upper left corner correctly.

When the image of the left, right, upper, and lower horizontal / vertical positions of the corner portion displayed on the screen of the CRT 400 is correctly viewed, the microcomputer 200 displays an image at the corner of the screen of the SCRT 400 It is determined whether the horizontal / vertical position movement is to be terminated (S311). If there is no separate "key" input for terminating the horizontal / vertical position movement of the corner portion of the screen in the determined result input unit 220, the horizontal / vertical position movement of the corner portion of the CRT 400 screen will continue, Sequentially transmits control commands to the one frame image storage unit 720, the horizontal position movement unit 712, and the vertical position movement unit 714 through the command reception and control unit 710 of the screen position movement device 700 (S304).

The microcomputer 200 determines whether the horizontal / vertical position movement of the corner of the screen of the CRT 400 is to be terminated (S311) and moves the horizontal / vertical position of the screen of the CRT 400 in the key input unit 220 The microcomputer 200 outputs a control signal to the image processor 300 and outputs the control signal to the image processor 300 so as to be processed in the image processor 300. [ The video signal of the broadcasting signal is amplified to a certain level via the video amplifying unit 320 and is displayed on the screen of the CRT 400 so that the viewer watches the normal video (S312).

As described above, according to the present invention, when a viewer selects a screen position shift "key ", an image displayed on the upper, lower, left, and right corners of the TV screen is automatically shifted up / So that the image of the edge portion of the screen can be accurately viewed.
