Next, the operation of the panoramic screen control apparatus of the television according to the present invention having the above-described configuration will be described in detail with reference to an example of the panoramic screen shown in FIGS. 3A and 3B.

First, the controller 12 waits for input of a remote control signal by the remote controller 10 in a state in which a video / audio signal is reproduced in response to a preceding channel selection station (for example, a last memory channel). When the remote control signal is inputted from 10), it is determined whether the remote control signal is a signal by an operation of the button 10a for setting the function of the panoramic screen provided in the remote controller 10.

As a result of the determination, when it is not a remote control signal for setting the display function of the panoramic screen, the controller 12 performs processing of a video / audio signal corresponding to the remote control signal.

That is, for example, when a remote control signal for tuning of a specific channel is input from the remote controller 10, the controller 12 transmits the channel data for the channel to be tuned by the remote controller 10 to the channel data storage unit ( 14 is applied to the tuner 16, and the voice signal received in the channel tuned by the tuner 16 is subjected to voice IF conversion by a voice processing system (not shown). It is processed by the volume adjusted by the volume control function of the output from the speaker device (not shown), and the image signal of the channel tuned by the tuner 16 is detected by the image IF module 18 and then converted to IF Amplified and applied to the image multi-screen processor 22.

Then, the video multi-screen processing unit 22 sets the video signal set by the remote controller 10 to the IF converted video signal applied from the video IF module 18 when the display function of the panoramic screen is not set. The video signal is reproduced on the CRT device 25 by processing it based on the control (e.g., brightness, contrast, color amount, etc.) and applying it to the CRT device 26 through the image output unit 24.

On the other hand, when the display of the panoramic screen is designated by the button 10a for setting the panoramic screen display function of the remote controller 10, the control unit 12 sets the execution mode of the panoramic screen display function and then the panorama. The display variable control unit 20 outputs a control signal EN1 for setting a reference timing for processing a normal panorama screen.

Then, the synchronization signal detection unit 30 detects horizontal and vertical synchronization signals (Hsync / Vsync) from the image signals processed by the image multi-screen processing unit 22 and applies them to the counter 32. In 32), the count results of the horizontal and vertical synchronization signals (Hsync / Vsync) are provided to the control signal generator 34.

The programmable timer 36 outputs a timing signal T for dividing a timing (for example, 1 sec) for forming a nine-split panorama screen based on the count result of the counter 32. In addition to the above, the still picture recording mode is set for the still picture memory 40, and the address AD of the still picture unit is applied.

Therefore, in the programmable timer 36, the clock signal CLK1 for obtaining a still image of at least 1/60 sec (this is a unit time for imaging / displaying one scene in the odd / excellent field) based on the timing signal T. Is applied to the analog-to-digital converter 38, and accordingly, the analog-to-digital converter 38 digitally converts an image signal passing through the sync signal detector 30 to the still memory memory 40. do. Therefore, in the still image memory 40, still images every 1/60 sec are stored under the designation of the address AD.

Next, the still image stored in the still image memory 40 by designation of the address AD is set in the digital mode in a state in which the read mode is set by the control signal R / W 'in the control signal generation section 34. Read out to the analog converter 42, in which case the control signal generation section 34 transmits to the still picture memory 40 on the basis of the reference timing signal T (e.g., 1 sec) set in the normal 9-division panoramic mode. The stationary memory 40 is accessed to generate nine addresses AD, and thus, the still image 40 is read from the still image memory 40 and applied to the digital-to-analog converter 42. Will be.

The 9-part panoramic still image applied to the digital-analog converter 42 is analog-converted by the clock signal CLK2 of the programmable timer 36 and applied to the image multi-screen processor 22, which is the image. The 9-split panoramic screen applied to the screen processing unit 22 is applied to the CRT device 26 through the image output unit 24 after the processing for display on the CRT device 26 is performed. The CRT apparatus 26 displays a nine-part panorama image (see FIG. 3A).

Subsequently, when a nine-partition panoramic screen shown in FIG. 3A is displayed on the CRT apparatus 26, a specific panoramic screen designation (for example, ⑦) is performed by the 10-key 10b of the remote controller 10. The control unit 12 applies the designation of the panoramic screen to the control signal generation unit 34 by the control signal EN1.

Then, the control signal generation unit 34 is a timing signal T which is subdivided compared to the timing signal T applied to the programmable timer 36 in the process of processing the panoramic screen; at least 1/9 sec- For the time difference existing between the '⑦' screen specified in the panoramic screen and the subsequent '⑧' screen among the 9-split panoramic screens recorded in the still image memory 40 based on the setting in the 1 / 60sec range). The address signal AD at a timing of approximately 1/9 sec to 1/60 sec or more is applied to the still memory 40.

Accordingly, nine still picture accesses are executed between the '⑦' screen and the '⑧' screen stored in the still picture memory 40, and the still picture is analog-converted by the digital-analog converter 42 to perform the image multi-screen processing unit. It is applied to the 40 and is processed into a more detailed 9-split panorama screen, which is displayed on the CRT apparatus 26 through the image output unit 24 (see FIG. 3B).

Meanwhile, the present invention may allow a variable setting for the subdivided timing when the 9-split panorama screen is displayed in a subdivided form in the parallax of the screen adjacent to the screen designated by the 10-key 10b. .

As described above, according to the control apparatus for a panoramic screen of a television according to the present invention, a nine-part panorama of a still image more precise in the parallax existing between a screen specified among the panoramic screens displayed on the CRT apparatus and a subsequent screen The screen can be implemented.
