A feature of the apparatus and method for adjusting the function of an image display device using a jog shuttle according to the present invention for achieving the above object is to adjust the screen and sound of the image display device using a cathode ray tube or a liquid crystal display device. The Jog Shuttle has a one-touch function.

Hereinafter, a preferred embodiment of an apparatus and method for adjusting a function of an image display apparatus using a jog shuttle according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2a is a perspective view showing the appearance of the function adjusting device of the image display device using the jog shuttle to which the present invention is applied, the front case 10, the screen display unit 20, the external mounting speaker 30, the power supply terminal 40 And jog shuttle (60) having a one-touch function.

In the configuration as described above, the function of the image display device such as changing the channel of the state of the screen displayed on the screen display unit 20 of the image display device or the sound output through the external mounting speaker 30, and changing the channel is user Is performed as the jog shuttle is operated, and the degree of adjustment is displayed on the screen display unit 20 as a number or a bar graph by the On Screen Display (hereinafter, abbreviated as “OSD”) function (see FIG. 2B). .

3 is a block diagram showing an embodiment of a function adjusting apparatus of an image display apparatus using a jog shuttle to which the present invention is applied, and the electric signal for the displacement of the jog shuttle adjusted externally by the user is a jog shuttle signal detecting unit 31. N input terminals of the microcomputer 32 are connected to the function adjusting unit 34 of the image display device, and the plurality of other The output terminal is connected to the input terminals of the OSD unit 33, which are means for displaying the state of the function adjustment on the screen display unit 20. FIG. Here, the function adjusting unit 34 of the image display device includes N function adjusting circuits such as a screen state, a channel, and a voice, which the user wants to adjust with the jog shuttle, and the output terminal and the OSD unit 33 of the microcomputer 32. In the case of a black and white image display device, a signal line electrically connecting the input terminals of N) is required, and in the case of a color image display device, red (R), green (G), and blue (B) thin lines are required. The output signal of the OSD unit 33 is combined with the video signal and output to the video display device. The microcomputer 32 not only controls the overall operation of the image display apparatus but also receives an input signal of the jog shuttle according to the user's adjustment, and then adjusts the function of the image display apparatus based on a method of adjusting the image display apparatus set as a program. 34) and outputs a signal for controlling the OSD unit 33, respectively.

4 is a flow chart showing a preferred embodiment of a method for adjusting a function of an image display apparatus using a jog shuttle according to the present invention, which is performed by a microcomputer 32 that controls the overall operation of the image display apparatus. .

In the above process, the process of entering into the function adjustment mode (S1) by the input of the one-touch function key 61 integrated with the jog shuttle as a whole, and the number displayed on the screen display unit 20 as the function adjustment mode is entered. It consists of a process of selecting a specific function (S2) of the dog function, and the process of adjusting the selected function (S3), and after adjusting the selected function is to enter the function adjustment mode again (S1).

The process of entering into the function adjustment mode (S1) is 'start' from the original display state to determine whether the one-touch function key 61 signal of the jog shuttle 60 having a one-touch function is input, if it is entered Entering the function adjustment mode while displaying the adjustment functions on the display unit 20 in the OSD method or a graphic icon (Graphic Icon), and continues to display only the original screen if not entered. If the function selection signal is not inputted by the rotation of the jog shuttle 60 until the set time elapses despite entering the function adjustment mode, the display returns to the original screen and the function selection signal is inputted. Enters the function selection process (S2).

Entry to the function selection process (S2) is made by selecting a specific function by the rotation of the jog shuttle 60 when the initial one-touch function key input enters the function adjustment mode and the set time has not elapsed. After selecting, it is determined whether the one-touch function key 61 signal is input, and if it is not input, it is determined whether the set time has elapsed, and if the set time has elapsed, the screen is returned to the original screen and if the set time has not elapsed, another touch Determines the presence or absence of a function key input signal. Here, when the one-touch function key 61 signal is input, it is determined whether the selected function is 'save setting value', and if it is 'save setting value', the original screen is stored after storing the adjusted value in the adjustment process for each function (S3). If the 'Save setting' key is not selected, it is determined again that the selected function is 'unselected'. If it is 'unselected', it returns to the original screen. It enters the process of adjusting by function (S3).

In the above-described function adjustment step (S3), according to the signal passed through the function selection process (S2) as described above, only the corresponding function is displayed in the OSD mode or a graphic icon to enter the adjustment mode for each selected function to enter the jog shuttle ( 60) While the adjustment is performed, the change is continuously displayed as a number or bar graph using the OSD function. If the input signal of the one-touch function key 61 is not input until the set time elapses after the adjustment of the corresponding function, the screen returns to the original screen and the function adjustment process of the image display device is 'ended'. On the other hand, if the one-touch function key 61 signal is input, as described in the above-described function selection process (S2), it is again entered into the function adjustment mode (S1) to save or cancel the selection. The final decision is made.

In the above-described process, returning to the original screen after the set time has elapsed is one way to disregard this when a signal of an incorrectly pressed one-touch function key is input. You can decide. In addition, if the image display device that requires adjustment of a function such as a screen, an audio display, or a channel may be applied to other image display devices as well as an image display device using a cathode ray tube and a liquid crystal display device.

According to the function adjusting apparatus and method of the image display device using the jog shuttle according to the present invention as described above, the one-touch as the function of the screen state and sound of the image display device using a cathode ray tube, a liquid crystal display element, and a channel, etc. By using the jog shuttle and microcomputer control device and method, and displaying the adjustment status on the screen display, the user can feel high satisfaction from the user's point of view due to its simple design and function, Can be easily adjusted, and the mechanical simplicity has the effect of increasing the efficiency of the development process and production process and reducing the product cost for the developer or producer.
