The present invention relates to an option control method of a TV, and more particularly, to an option adjustment method of a TV to prevent the extreme adjustment state by setting the maximum and minimum when setting the limit mode according to the option.

1 is a block diagram showing a general TV configuration, the tuner unit 10 for receiving the RF signal received through the antenna to convert the desired channel into the IF signal as shown therein; A voice processor 11 which receives a voice signal of the tuner unit 10 and processes the voice signal according to voice related data; A speaker 12 which receives a signal from the voice processor 11 and outputs the signal; An image processor 16 which receives an image signal from the tuner unit 10 and processes the image signal according to image related data; A CIF processing unit 17 which receives an image processing signal of the image processing unit 16 and adjusts it to fit the CPT; A CFP output unit 18 which receives a signal of the CTP processing unit 17 and outputs the signal; A remote control receiver 14 which receives a key signal of the remote controller 13 and transmits it; It is composed of a microcomputer 15 for receiving the received signal of the remote control receiving unit 14 and a predetermined operation to output the image-related data and audio-related data.

2 is a flowchart of a conventional TV option control method, comprising: a first step of determining a state of a data key as shown therein; As a result of the determination of the first step, if the data increasing key is used, the current OSD mode is checked, and if the video OSD mode, the data of the corresponding video RAM is stored in a register, and if the audio OSD mode is used, the corresponding voice Storing the data of the RAM in a register, and storing the data of the corresponding volume RAM in a register in a volume OSD mode, and comparing the value stored in the register with an adjusted maximum value; As a result of the determination of the first step, if the data reduction key is used, the current OSD mode is checked, and if the video OSD mode is used, the data of the video RAM is stored in a register, and if the audio OSD mode is used, the corresponding voice Storing the data of the RAM in a register, storing the data of the corresponding volume RAM in a register in a volume OSD mode, and comparing the value stored in the register with an adjusted minimum value; If the value stored in the register is less than the adjusted maximum value as a result of the determination in the second step, the value of the register stored in the register is increased by one, the increased value is stored in the corresponding RAM, and the variable data is stored in the voice processing unit ( 11) and a fourth step of outputting to the image processor 16 and outputting the corresponding OSD; If the value stored in the register is greater than the adjusted minimum value as a result of the determination in the third step, the value stored in the register is decreased by one, the increased value is stored in the corresponding RAM, and the variable data is stored in the voice processor 11 and the image. A fifth step of outputting to the processing unit 16 and outputting the corresponding OSD.

The conventional TV option adjusting method configured as described above will be described with reference to the flowchart of FIG. 2.

First, the microcomputer 15 determines the state of the data key. If the determination result is the data increase key, the microcomputer 15 checks the current OSD mode. If the image OSD mode is used, the microcomputer 15 stores the data of the corresponding video RAM in a register. In the case of voice OSD mode, the data of the corresponding voice RAM is stored in the register, and in the volume OSD mode, the data of the corresponding volume RAM is stored in the register.

The value stored in the register is then compared with the adjusted maximum value.

If the value stored in the register is smaller than the adjusted maximum value, the value stored in the register is increased by 1 and the increased value is stored in the corresponding RAM.

On the contrary, the microcomputer 15 determines the state of the data key. If the determination result is the data reduction key, the microcomputer 15 checks the current OSD mode. If the image OSD mode is used, the microcomputer 15 stores the data of the corresponding video RAM in the register. In the case of voice OSD mode, data of the corresponding voice RAM is stored in the register. In the case of volume OSD mode, the data of the corresponding volume RAM is stored in the register.

The value stored in the register is then compared with the adjusted minimum value.

At this time, if the value stored in the register is larger than the minimum value of adjusting the value stored in the register, the value stored in the register is decreased by 1 and the increased value is stored in the corresponding RAM.

Then, the microcomputer 11 outputs the variable data stored in the RAM to the audio processing unit 11 and the image processing unit 16 so that the user can change the data while watching the changing data. Outputs (OSD) so you can easily feel the data change.

However, in the conventional method as described above, when the user approaches the minimum or maximum value of the brightness or contrast, it is too dark or too bright to view the color, and when the color and the color concentration approach the minimum value or the maximum value, the color cannot be reproduced properly. There was a problem.

In addition, if the sound-related data is biased to one side, one speaker may not be output, and the high and low sounds may also be distorted when the sound is close to the minimum or maximum value.

Therefore, the present invention devised in view of the above problems does not control the adjustable data uniformly, but rather restricts the general mode and the maximum value and the minimum value range that the user generally adjusts, so that the variable value is limited to this limited minimum or maximum value. The purpose of the present invention is to provide a method of controlling data options of a TV, which can be conveniently used by a general user by providing a limited mode that enables the user.

The above object is the limit range setting step of setting the minimum value and the maximum value of the volume data, the audio data and the image data by the option key signal; The present invention will be described by performing the limited range execution step of appropriately varying the volume data, the audio data and the image data within the minimum value and the maximum value setting range by the data increase / decrease key signal.

3 is a flowchart of an option adjusting method of a television of the present invention, and as shown therein, a limit range setting step of setting a minimum value and a maximum value of volume data, audio data and video data by an option key signal; The data increase / decrease key signal is performed in a limited range execution step of appropriately varying the volume data, the audio data and the image data within the minimum and maximum value setting ranges.

The limit range setting step includes: a limited mode checking step of determining whether a current option state is a normal mode; A limited data setting step of changing the option mode to the normal mode, adding the predetermined value to the minimum value of the limited mode, and setting the maximum value by adding the predetermined value to the maximum value of the limited mode; A maximum / minimum value setting step of switching the option mode to the limit mode in the normal mode, setting the limit minimum value to the minimum value and setting the limit maximum value to the maximum value; The set value storing step of storing the minimum value and the maximum value set in the step and outputting the OSD accordingly.

The limit range execution step includes a current mode determination step of checking a mode according to the data increase / decrease key signal being input; A data adjustment step of varying and adjusting the corresponding adjustment data in a range between a minimum value and a maximum value determined by the option; The audio and volume related data among the adjusted data are output to the audio processing unit 11, and the image related data is output to the image processing unit 16, and the corresponding OSD is output accordingly, so that the viewer can easily change the amount of data. It consists of a comparison of maximum and minimum limit values.

The operation of one embodiment of the present invention configured as described above will be described with reference to FIG.

First, when the option key is entered, the current option status is checked.If the current option is the normal mode, after switching the option to the limit mode, the minimum value is set to the variable limit minimum value and the maximum value is also set to the variable limit maximum value. .

If the current option is the limited mode, the option is converted to the normal mode, and the predetermined value alpha is added to the minimum value of the limited mode as shown in the data variable range of FIG. Add (beta) and set it to the maximum value.

Here, the predetermined value is an arbitrary value determined so that even if the viewer selects the data as the minimum value or the maximum value, there is no inconvenience in viewing and the data can be appropriately changed to suit the taste.

When the option is set as described above, that is, after the limit range is set, the user inputs a data increase / decrease key to adjust the data.

Accordingly, when the data increase / decrease key signal is input, the microcomputer 15 checks the OSD mode accordingly and determines the current mode.

Subsequently, the corresponding adjustment data is adjusted in a range between a minimum value and a maximum value set by the option, and the audio and volume related data among the adjusted data are output to the audio processing unit 11 and the image related data is output to the image processing unit. And outputs the corresponding OSD accordingly.

Accordingly, the viewer can easily know the data variability.

As described in detail above, the present invention sets the limit mode according to the option in addition to the normal mode to set the minimum and maximum adjustable values of the data, thereby preventing the user from switching to the extreme adjustment state by the user's mistake. There is.
