Description

Output screen control method by user setting of TV

The present invention relates to a method for adjusting the output of a television screen when performing a function such as a television screen output, a video image signal output, or a game screen output. When watching TV, video output, or game, the screen is automatically converted to the screen set by the user.

In general, TVs are equipped with extra input ports for outputting external input signals such as game consoles for teenagers, high-quality VHS, and general VHS, and the output state of the screens input through these devices includes brightness, contrast, and tint. Like the television screen, the user had to adjust the settings manually.

First, the configuration and operating state of a conventional television will be described with reference to FIG.

As shown, the television receiver includes an antenna 1, a tuner 2, an IF amplifier 3, a P / S separation unit 4, a voice detector 5, a voice processor 10, and a voice amplifier. A unit 11, a speaker 12, an OSD generator 13, an image detector 6, an image processor 14, a mixer 15, a remote controller 7, a receiver 8, storing data And a microcomputer 9 to which a memory device E ² PROM is connected, a voice amplifier 11, a speaker 12, a CRT driver 16, a CRT 17, and the like.

The operating state of the television is as follows. The aerial signal is received by the antenna 1, and a specific broadcast signal is tuned among the signals received through the tuner 2 controlled by the microcomputer 9. The IF amplifier 3 amplifies an intermediate frequency (IF) signal output from the tuner 2, and the P / S separation unit 4 includes a surface acoustic wave filter to convert the intermediate frequency (IF) into an image intermediate frequency ( PIF) and voice intermediate frequency (SIF).

The voice detector 5 detects a voice signal from the voice intermediate frequency (SIF), and the voice processor 10 detects the detected voice signal based on the control signal of the microcomputer 9 (Base) and Treble. Voice processing such as volume, volume, etc. is performed, and the processed voice signal is amplified by the voice amplifier 11 and output to the speaker 12.

On the other hand, in the image intermediate frequency (PIF), the image signal is detected by the image detector 6, and the image signal detected by the image processor 14 according to the control signal of the microcomputer 9, color, tint, brightness, etc. Process the R (Red), G (Green), B (Blue) and luminance (Y) signals corresponding to the video signal, and the R, G, B and luminance (Y) signals are output from the mixer 15. By mixing and outputting the R ', G', B 'and OSD blanking signals Y' generated from the OSD generator 13, the CRT 17 is driven through the CRT driver 16, and the OSD generator 13 The image is displayed together with the predetermined OSD pattern data.

Control data (contrast, brightness, color, tint, sharpness, volume, etc.) for such an output screen is normally output as a menu screen to a CRT of a television, set by a user, and stored in a memory element.

The remote control device 7 is a device for the viewer to control the output volume, change the channel, or remotely control the whole other devices, and transmits an infrared signal and receives the received signal from the receiving unit 8 of the television and converts it into an electric code signal. By outputting to (9), the whole apparatus is controlled by the microcomputer 9 according to the electrical code signal. In addition, the microcomputer 9 detects an external input such as a video signal or a game and outputs a necessary signal through the CRT 17 through an output switching or the like.

However, in the conventional television, there is an inconvenience that the user has to change the screen output data whenever the television signal output, game screen output, or video signal screen output is changed. For example, since the video signal has different storage properties of colors depending on the recording state, when the user switches to the video mode while watching television, the user must control the video output state again using a remote controller or the like.

In addition, if the input signal is changed to play a game while watching TV, the screen output state is set to a TV output screen mode, and the screen output state is not suitable for playing a game. In other words, the screen output mode suited to the television screen is output with too strong color in the game mode, so it is common to reduce the contrast and enhance the brightness to protect the eyesight. Therefore, it is inconvenient to adjust the contrast, brightness, tint, etc. to adjust the output screen every time the mode is changed to watch a TV and play a video or a game, or after the video watching or a game is switched back to the TV. There was a ham.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to set a user's preference when inputting screen output control data in a user's preferred state and watching TV, video output, or game. An object of the present invention is to provide a method of controlling an output screen by user setting of a television that enables output on one screen.

According to the present invention, there is provided a method for controlling an output screen according to a user setting of a television, including a tuner (2) for outputting a signal of an airwave broadcasting station, a microcomputer (9) incorporating a program for controlling a television, and an image for video signal processing. In the television comprising a processor 14, an OSD generator 13 for displaying a menu screen, and an external input terminal for selectively outputting a game screen or a video image screen by a microcomputer 9, Inputs, through the menu screen, preferred screen output control data for the specific screen and stores it in the specific memory means; The microcomputer detects the screen output operation state of the television while the screen output control data is stored; Reading screen output control data for the output screen currently output through the CRT of the television according to the detection result of the screen output operation state from the memory means; And outputting a command signal from the microcomputer to the image processing unit so as to control the output screen according to the read screen output control data. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

According to the method of the present invention, first, a menu screen is output for setting screen output control data for a specific screen output, that is, a television screen, a video screen, or a game screen output. The menu screen is included in the function of the conventional television. In the present invention, the menu screen can be easily configured by changing the program.

In the menu screen, the character pattern data generated from the OSD generator 13 by the control signal of the microcomputer 9 is mixed with the television image by the mixer 15 and finally output through the CRT 17. The call of the menu screen is usually started when a command signal from the remote controller 7 is input to the microcomputer 9. The screen output control data set by the user in the menu screen is stored in the memory element of the microcomputer 9.

3A to 3B illustrate a process of inputting screen output control data through a menu screen. The menu screen output by the user is, for example, TV screen output control data setting (FIG. 3A), VIDEO screen output control data setting (FIG. 3B), and the like. Of course, it is apparent to those skilled in the art that the menu screen may be configured differently from the illustrated embodiment. The menu screen can be directly output on each screen during TV viewing, video watching or game so that control data can be easily set.

The user can input the control data so that the screen desired by the user is output through the key operation in the control data input state output on the menu screen using the remote controller 7. This is performed essentially the same as the control data setting process of the conventional television. In the microcomputer 9 of the television, it is possible to reconfigure the program so that the screen state set by the user can be immediately confirmed by outputting the screen state immediately according to the control data input from the user.

Each screen output control data is input to the microcomputer 9 and finally stored. Screen output control data can be stored by adding a separate ROM because the amount of data stored is increased.

4 is an allocation table of screen output control data stored in a memory element. That is, among the screen output control data, the contrast data of the television (TV) is stored at an address having WTVCONT, and the brightness data is stored at each address having a WTVBRIGH. As shown, not only television but also data on game and video output screens are also stored.

When the screen output control data is input, set and finally stored in the menu screen as described above, the microcomputer 9 senses the output screen mode of the television. When the television is off, the screen output control data of the television is selected as the default setting state.

When the television is on and the user enters a command to watch the video tape while watching the television, the microcomputer 9 detects this and changes the screen output control data. Detection of mode switching of the television can be easily recognized since the control signal input from the user is received by the microcomputer 9.

In other words, when switching to the video mode, the control signal is output to the image processing unit 14 that processes the video signal before being output to the CRT 17 to adjust the state (contrast, brightness, tint, etc.) of the video output screen. The screen output control data used at this time is read out from the memory element by the microcomputer 9, and is initially set on the menu screen by the user to become a value stored in the memory element. In the screen output control data for the video output, control values stored at addresses (WVCONT, WVBRIGH, WVCOLOR, WVTINT, WVSHARP, WVVOL) of the memory elements are read out and used.

In addition, when a user wants to play a game while watching a video, a control signal is input through the remote controller 7 to switch to the game mode, and the microcomputer 9 detects this and outputs a screen of a game of a memory device connected to the microcomputer 9. Read the data from the address (WGCONT, WGBRIGH, WGCOLOR, WGTINT, WGSHARP, WGVOL) where control data is stored. Using the read data, the microcomputer 9 controls the image processing unit 14 to control the screen output state.

As the output screen mode is changed as described above, the output screen is automatically adjusted to suit the changed mode, so that the user can watch the video without the need for readjustment according to the output screen mode change as in the prior art.

If you want to change the screen output control data for each screen, as described above, it is possible to set a new data value in the menu screen. Also, the screen output control data initially set by the TV manufacturer can be set to the default value so as to return to the initial state.

As described above, according to the present invention, the screen output control signal of a user's preferred state is input in advance, and when the user is watching TV, video output, or a game, the user can automatically convert to the screen set by the user and output it.

While the embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto, and the present invention may be variously modified and changed without departing from the spirit or the field of the present invention. It will be readily apparent to those of ordinary skill in the art.
