BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a channel display image processing apparatus on a television screen, and more particularly, to an apparatus for processing a change of a channel into a stereoscopic image on a television channel up-down television screen.

In general, when the television is turned on, an indication of the channel currently being broadcast is displayed at the corner of the television screen by the user's selection. In addition, when the channel is changed by the user's selection, the channel display is correspondingly changed. The channel display of this screen allows the user to easily recognize the broadcasting station currently broadcasting. However, in the situation where image processing technology that takes the advanced state using graphics is being developed as it is today, users who have tasted a lot of image processing splendidly displaying only Arabic numerals require more sophisticated image processing.

Accordingly, an object of the present invention is to display an image in which a calendar changes a channel change or an image in which a calendar is stuck upside down as if a film is rotated upside down on a TV channel up-down. In the meantime, it provides more sophisticated screen effects.

According to an aspect of the present invention, there is provided a television channel display image processing apparatus including: a receiver configured to receive a predetermined signal waveform corresponding to a selected channel according to a user's channel selection; converting the received signal waveform into a predetermined value and converting the data into a predetermined value A video signal generator for generating a signal to display the data in the number and graphics of the selected channel; a display unit for image processing the signal generated by the video signal generator; And a control unit for controlling the overall procedure of the receiver, the data storage unit, the image signal generator, and the display.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a block diagram illustrating a television image processing apparatus according to the present invention. In FIG. 1, reference numeral 10 denotes a receiver which receives a signal according to a signal transmission of a predetermined input device (e.g., a remote control apparatus, etc.) in a television control, and 12 denotes a receiver. A data storage unit converts the received signal waveform into a predetermined value and stores the data as data. 14 denotes a signal for displaying the data stored in the data storage unit 12 as the number and graphic of the selected channel selected by the user. An image signal generation unit 16 is a display unit for displaying a predetermined signal encoded by the image signal generation unit 14, and 18 is a control unit for controlling the signal of the above procedure.

2 is a diagram showing television image processing according to the present invention. When the channel-up (CHANNlEL-UP), the calendar is shown as a flying image, while the channel-down (CHANNEL-DOWN) is a view that looks like the above picture is reversed, that is, the calendar is flying back and covered. . In FIG. 2, reference numeral 20 is a television screen, 22 is a block for displaying the current channel in Arabic numerals, 24 is a block for displaying Arabic numerals minus "1" in the Arabic channel of the current channel, and 26 is This block displays Arabic numerals minus "2" from the Arabic numerals of the current channel. Also, the value of each channel is not infinitely small or infinitely large, and the maximum channel value plus "l" has the minimum channel value, and the channel value is changed to the maximum channel value by subtracting "1" from the minimum channel value. Is done.

3 is a flowchart of the control unit 18 for controlling the display of the current channel on the TV screen of FIG. Referring to FIG. 3, step 100 is a step of determining whether the received signal is channel-up. If the received signal is channel-up, the flow of logic is developed in step 110, and if the received signal is not channel-up, In step 120, the flow of logic is developed. In step 110, if the channel-up in step l00 is true, 1 is added to the channel on the current television screen to be the current channel. In step 130, the current channel determined in step 110 is compared with the maximum channel. Here, the maximum channel refers to the maximum channel that can be taken maximum among the minimum channel and the maximum channel set for each of the high frequency channel (VERY HIGH FREQUECE CHANNEL) and the ultra high frequency channel (ULTRA HFGH QUENEL CHANNEL). will be. Likewise, the minimum channel refers to the channel that can be taken to the minimum. If the current channel is less than or equal to the maximum channel in step 130, the logic flows to 140 to display the current channel on the television screen. On the other hand, if the current channel is larger than the maximum channel, the flow of logic is displayed on the screen. The flow of logic develops in stages. The flow of logic linked in step 120 will be omitted because it is similar to the flow of logic described above.

4 is a diagram for explaining a block for displaying channels 22, 24, and 26 of FIG. 2 when the current channel selected by the controller 18 in FIG. 1 changes according to the logic of FIG. As shown in FIG. 2, a block 22 for displaying the current channel in Arabic numerals is provided, and blocks 24 and 2 for displaying Arabic numerals minus "1" in the Arabic numerals of the current channel. A block 26 for displaying Arabic numerals minus or a block (not shown) for displaying Arabic numerals minus “3” is set, and each block 22, 24, or 26 is displayed to continuously change the channel. Can provide an interesting picture effect for the TV user.

On the other hand, when the channel is not changed, the block 22 indicating the current channel and the other blocks 24 and 26 are not displayed.

As described above, the TV image processing method according to the present invention has an effect of causing an interest to the TV user by finely processing the image of the channel change during the conversion of the TV channel.
