In this configuration, the key input unit 10 is an input means for performing the operation of the television, and adjusts the image quality such as volume up / down keys, contrast and brightness and color, or adjusts setting values such as image quality or volume. A menu key for setting a variable amount per range and adjustment level, a menu selection up / down key, a menu selection key, and a plurality of keys, and a key corresponding to a user's key operation using a remote controller that can be input remotely. The signal is loaded on a predetermined infrared carrier and transmitted, the key signal loaded on the received infrared carrier is amplified and detected and applied to the microcomputer 20.

On the other hand, the microcomputer 20 controls the overall operation of the television by controlling the tuner unit 40, the image / audio signal processing unit 50, the OSD unit 60, etc. in response to the key signal applied from the key input unit 10. In particular, when a predetermined key signal for setting the user's adjustment information is applied from the key input unit 10, the adjustment range and variable per adjustment level of each setting value (for example, volume, contrast, brightness, color) are variable. Display a predetermined menu screen for receiving the respective amounts by controlling the OSD unit 60, and adjusts the adjustment range and the variable amount per adjustment level of each set value set based on the key signal for selection from the key input unit 10 The storage is controlled in the information storage unit 30.

In addition, the microcomputer 20 has a predetermined key signal for adjusting various set values from the key input unit 10, for example, a volume up / down key signal and a key signal for various image quality adjustments such as contrast, brightness and color. If applied, the adjustment information storage unit 30 searches whether the adjustment range and the variable amount per adjustment level of the set value are stored, and if so, reads out the adjustment range and the variable amount to adjust and control the volume and image quality.

That is, the microcomputer 20 selectively outputs a predetermined volume control signal (PLL data) for volume control or a predetermined image quality control signal (PLL data) for image quality control to the image / audio signal processor 50 in response to a key input. The image / audio signal processor 50 controls the volume of the output audio and controls the image quality of the displayed image.

The image signal to be output is increased or decreased in units of levels, and the contrast, brightness and color are adjusted in units of levels.

On the other hand, the OSD unit 60 reads out a text signal corresponding to the control of the microcomputer 20 and synthesizes the video signal from the video / audio signal processing unit 50 or the blue-back video signal to monitor 70. To control the output.

Next, a description will be given in detail with reference to the flowchart of FIG. 2 attached to the process of varying the adjustment range in the television according to the preferred embodiment of the present invention in the television including the above-described configuration.

First, the user performs a desired operation of the television by a predetermined key operation of the key input unit 10, and also various states, for example, voice mode such as stereo / mono, volume, or sound quality and contrast or brightness The image quality and reception channel are set to the optimum state to suit your taste.

That is, the user alternates the main menu or the sub-menu by key operation of the key input unit 10 to set various states, and this operation becomes a very inconvenient task for the user. You want to keep it.

Therefore, in order to keep the various setting values of the television set in this way safely, the user limits the adjustment range of setting values such as volume, contrast, brightness and color, and also changes the variable amount per adjustment level to his or her preference. If it is easy to reset, even if other users change the environment after setting the viewing environment of the TV to the optimal state, it is easy to change the adjustment to the optimal state again based on the limited adjustment range, and By resetting the variable amount per adjustment level of the environmental state to suit your taste, you can set it directly to the state you want with one key operation in that state.

Therefore, the user first performs a predetermined key operation for setting the adjustment information provided in the key input unit 10 in order to set the adjustment range and the variable amount per level, wherein the microcomputer 20 receives the key input unit 10 from the key input unit 10. It is determined whether a key signal for setting the above-mentioned adjustment information is applied (step 200).

At this time, when a key signal for setting adjustment information is applied from the key input unit 10, the microcomputer 20 controls the OSD unit 60 to set respective setting values (for example, volume, contrast, brightness, color). A predetermined menu screen for receiving input of the adjustable adjustment range and the variable amount per adjustment level is displayed (step 202).

Next, the user manipulates a predetermined key provided in the key input unit 10 while viewing the displayed predetermined menu screen to set and input a volume adjustment range, contrast adjustment range, brightness adjustment range, color adjustment range, and the like. For each level of adjustment of each adjustment range, that is, a variable amount adjusted by one key input is set and input.

Accordingly, the microcomputer 20 determines whether such adjustment information is input (step 204), and when the input information is input, the microcomputer 20 stores the input adjustment information in the adjustment information memory 30 (step 206).

Next, when the user sets the adjustment range and the variable amount per adjustment level of each of the set values based on the above-described process, the volume, contrast, brightness, color, etc. Will be adjusted.

That is, when a predetermined key signal is applied from the key input unit 10 to adjust setting values such as volume, contrast, brightness, color, and the like (step 208), the microcomputer 20 searches for the adjustment information memory 30. It is determined whether the adjustment range and the variable amount of the corresponding set value corresponding to the key signal are stored (step 210).

At this time, if there is no adjustment range and the variable amount set and stored by the user, the microcomputer 20 responds to the input key signal based on the initial adjustment range, that is, the initial adjustment range and the variable amount per level set as the factory default values. The volume control signal (PLL data) or the image quality control signal (PLL data) is applied to the image / audio signal processor 50 to variably adjust the set value (step 212).

On the other hand, if the adjustment range and the variable amount set and stored by the user in step 210 described above, the microcomputer 20 performs an image / audio signal processing unit 50 in response to the input key signal based on the stored adjustment range and the variable amount. Control is made to adjust the corresponding volume, volume, contrast, brightness, color, etc. (step 214).

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention, the adjustment range and the variable amount per level, which are the setting values that can be changed and adjusted on the television, and the variable amount per level are stored and stored according to the user's taste. By varying each setting value based on, the environmental condition of the TV set by the user can be safely maintained by limiting the adjustment range. Also, by setting a variable amount value per adjustment level arbitrarily, the user can set the desired environmental condition once. There is an effect that can provide convenience that can be set immediately by key operation.
