Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to display of adjustment items (for example, brightness level, hue level) in a television receiver or the like.

[0002]

2. Description of the Related Art Generally, television receivers, video tape recorders, and broadcast receivers have various adjustment items.
The adjustment items are adjusted by operating keys provided on the remote control transmitter or the operation unit.
By the operation, the microcomputer (hereinafter, CPU) in the main body resets the data of each adjustment item as adjusted, performs the adjustment, and displays the set value on the display unit, so that the viewer can see it. I am informing you.

FIG. 5 is a display of a conventional example of a television receiver. This display will be described in detail with reference to this figure. This figure shows an on-screen method in which a pattern display is performed as character information on a CRT which displays an image on a television receiver.

This figure is a display showing the volume, which will be described. In the volume display shown in this figure, the set volume value is converted into digital data, the number of patterns obtained from the pattern generating means is determined according to the digital value, and the pattern is displayed at a predetermined position. That is, the audio analog data is converted into digital data, and the value is displayed as the number of patterns in order from the lower left of the screen.

First, it is assumed that the volume is increased by operating a key from the state shown in FIG. In order to clarify the difference, the number of key operations is 6 times. Then, since the number of patterns is changed by one every two key operations, it is increased by three and becomes as shown in FIG. This can be obtained from the relationship between the change width of the adjustment amount and the display width, and other ratios may be used.

On the other hand, it is assumed that the key operation is performed only six times to reduce the volume. Then, the number of patterns is changed by one for every two key operations as described above, so it is reduced by three, as shown in FIG.

Here, it goes without saying that the output volume level changes with the change in the display.

FIG. 6 shows another display of the conventional example. This is different from FIG. 5 in that it has a reference value (standard value or center value (median value)) and adjusts by increasing or decreasing from that value. For example, the color saturation called color, the brightness called bright, the contrast, the hue called tint, the image quality called sharpness, etc. are adjustment items with reference values. Further, in terms of voice, adjustment items such as left and right balance also have reference values. Therefore, the method shown in the same figure is a method of displaying this reference value on-screen so that the viewer can easily know it.

This is because the shape C of the pattern signal at the center is made wider than the normal pattern, and when the plus (or right) key is operated, the pattern C of the wide shape is made.
When the pattern B is displayed on the right side and the minus (or left) key is operated, the pattern B is displayed on the left side of the pattern C.

Therefore, the difference between the reference value and the reference value was apparent to the viewer.

However, the problem here is that it is necessary to provide two types of display patterns: an adjustment item that changes from the minimum to the maximum, such as volume, and an adjustment item that increases or decreases with respect to a reference value, such as hue. There is.

Therefore, in order to carry out that, in general, the adjustment value is controlled, and in order to display it on the cathode ray tube, C
The program is created and controlled by the PU, and providing two types of display patterns complicates the program and causes an increase in the program capacity. This increase in program capacity has a drawback in that an expensive CPU must be used.

[0013]

As described above, when displaying two kinds of display patterns, the program is complicated and the cost of the CPU is prevented from increasing. It can be processed with a simple configuration.

[0019]

According to the present invention, the values of the adjustment items, which are conventionally displayed in two patterns, can be displayed in one pattern.

[0020]

1 is a circuit block diagram of an embodiment of the present invention. Reference numeral 1 denotes a signal inputted from the antenna 1a or a reproduced video signal reproduced from a video tape recorder, a laser disk or the like which is a video signal reproducing device 1b, selectively demodulates, performs signal processing, and extracts horizontal and vertical synchronizing signals In addition, it is a signal processing unit that outputs RGB signals that are the three primary colors.

The RGB video signal obtained by the signal processing unit 1 is reproduced as an image by the cathode ray tube 4 via the switching unit 3 and the audio signal is also demodulated and signal-processed and then output from the speaker 2. , Can be viewed.

At the time of viewing, the viewer may adjust the volume and the image. Normally, this adjustment is performed by a remote control device (remote control) or an operation unit 6 including an operation panel provided on the main body.

It is generally known to display on the cathode ray tube 4 so that the adjustment operation can be confirmed. That is,
As the processing, the control signal by the operation of the operation unit 6 determines which control data is controlled by the input unit 7, and updates the data of the storage units 8a to 8e storing each control data. , And inputs the updated data to the pattern signal generator 5.

The storage unit is a volume storage unit 8a for storing volume adjustment data, a brightness storage unit 8b for storing brightness level adjustment data of a video signal, and a hue storage for storing color level adjustment data of a video signal. It comprises a unit 8c, a contrast storage unit 8d that stores the adjustment data of the contrast level of the video signal, and an image quality storage unit 8e that stores the adjustment data of the image quality level of the video signal.

The pattern signal generator 5 determines the display position according to the horizontal synchronizing signal and the vertical synchronizing signal obtained from the signal processing unit 1, and synchronizes the data from the internal ROM having a predetermined character with this display position. Then, the pattern signal is generated.

Then, at least when the updated data is output, the RG from the signal processing unit 1 is generated by the switching signal from the switching signal generating unit 10 which generates the switching signal.
The B signal and this pattern signal are switched by the switching unit 3 and displayed on the cathode ray tube 4. The switching signal generator 10 is synchronized in timing by a horizontal synchronizing signal and a vertical synchronizing signal.

The above switching is performed only when the pattern signal is used.
One of the R, G, and B signals and the pattern signal is switched, and the remaining signals are set to the no signal level. As another method, the output from the pattern signal generator 5 is RGB.
Some of them are output as signals and all are switched by a switching signal. Furthermore, the switching unit 3 may superimpose the pattern signal on the RGB signal of the video signal without switching in this way.

Then, when the volume is adjusted, the same display as in FIG. 5 of the conventional example is displayed. Therefore, the volume adjustment data generates the pattern signal from the pattern signal generator 5 and outputs the RGB signal.
Is switched (superimposed) on the video signal of. That is,
With this configuration alone, the displays of FIGS. 5 and 6 shown in the conventional example can be performed.

Next, the constitution which is a feature of the present invention will be described. The various control value data in the storage units 8a to 8e are also input to the standard value determination unit 9. The standard value discriminating unit 9 stores the data of the standard value storage unit 9a (generally, ROM: read only memory) in which preset standard values are written for the brightness, hue, contrast, image quality, etc. of the adjustment items Compare with the data in. Then, when they match, a signal of matching information is output to the switching signal generating unit 10.

Then, the switching signal generator 10 receiving the signal outputs a standard switching signal. The standard switching signal controls the switching unit 3 so that the pattern signal is displayed on the cathode ray tube 4 in a color different from the normal color.

FIG. 2 shows the display of the cathode ray tube 4 in this case. In the figure, a is a display when it becomes a standard value (or may be a reference value), and b and c are the displays when it deviates from the standard value. For example, the pattern signal of FIG. 10A is displayed in green A, and the pattern signals of FIG.

In other words, the pattern signal has been reproduced as the G signal until now, but when the standard value is reached, the switching signal controls so that the pattern signal is reproduced as the G signal + R signal.

Therefore, the user can visually recognize when the standard value is reached during the adjustment.

Further, since the volume display pattern used conventionally can be used as it is for the display of the adjustment item having this standard value, it is not necessary to have much pattern information of the pattern signal generating section.

FIG. 3 is a flow chart for determining the display color in this embodiment. Although it can be implemented with a block configuration as shown in FIG. 1, it can also be implemented with a program having this flowchart, and is not particularly limited to the configuration of FIG.

This flow chart starts in S1 and S2
It is detected whether or not the adjustment operation has been performed, and this step is repeated until the operation is performed. When the adjustment operation is performed, the data of the corresponding adjustment item is updated in S3.

Then, in S4, it is determined whether or not the adjustment is an adjustment item having a standard value. Here, if the adjustment does not have a standard value such as the volume, the result is "NO", and the pattern is set to green in S8. On the other hand, if the adjustment has standard values such as brightness, hue, contrast, and image quality, it is determined in S5 whether the adjusted data value is equal to the standard value. If they match, the pattern is set to green in S8, and if they do not match, the pattern is set to yellow in S6. The set pattern is displayed on the cathode ray tube in S7.

Therefore, the same pattern can be used to display different adjustment items, and the color can be changed when the standard value is adjusted, which is difficult for the viewer. It becomes convenient.

Next, there is a display of FIG. 4 as a second embodiment. In this method, the pattern signal of only the standard value is made green, and the other patterns are displayed in yellow.
This can be achieved using the block diagram of FIG. However, the present embodiment differs from the first embodiment in that only the specific pattern when the adjustment value is the standard value is switched to the pattern signal by changing the RGB signal of the video signal to the display in different colors by the switching signal. As another method, there is also a method of supplying standard value data to the pattern signal generator 5 so that only the standard value pattern of the generated pattern signal is displayed in a different color.

According to this embodiment, when the standard value is adjusted as shown in FIG. 10A, the pattern D of a color different from the pattern B is displayed on the rightmost side. Then, when the adjustment value is shifted to the right, the color of the pattern is changed only for the standard value and a pattern having the same color as the pattern B is added to the right as shown in FIG. Therefore, it becomes clear that it deviates to the right from the standard value.

On the other hand, when the adjustment value is shifted to the left, the result is as shown in FIG. 7C, and the standard value is not displayed as a pattern, so that the pattern of the same color as the pattern D is not displayed. This reveals to the viewer that the deviation from the standard value is to the left.

Although the standard value is not shown in FIG. 6C, the standard value is displayed in addition to the standard value shown in FIG. In this case, when the adjustment value is displayed, it is possible to display the standard value at all times.

As described above, in this embodiment, only the standard value is displayed in the same shape pattern with only the display color changed, so that it is possible to share the pattern with the adjustment item having no standard value. The deviation from the standard value becomes obvious.

Next, a third embodiment will be described. This is a rewritable standard value storage unit 9b (for example, RAM: random acc) that stores standard values such as brightness, hue, contrast, and image quality of adjustment items in the standard value determination unit 9 of FIG.
Ess memory) is connected, the value of the storage unit 9b is set to the standard value described above, and the value is compared with the adjustment value.

Here, the standard value is reset by operating the standard value setting means (not shown) provided in the operation unit 6.
Then, the control information of the standard value is input from the input unit 7 to the standard value setting unit 11, the standard value is generated, and the standard value storage unit 9b.
Is stored.

The standard value after that is stored in the standard value storage unit 9
Use the new standard value stored in b.

Therefore, since the standard value can be arbitrarily changed by the viewer, it is possible to obtain the video and audio that the viewer likes. Moreover, since this can be used as it is in the first and second embodiments, the standard value set by the viewer can be easily expressed.

Here, when the rewritable standard value storage unit 9b is cleared or abnormal data is generated due to some influence, the standard value is read from the standard value storage unit 9a,
It can be written in the standard value storage unit 9b.

After the viewer rewrites the standard value,
If it is desired to restore the standard value at the time of factory shipment, the standard value from the standard value storage unit 9a can be registered again in the standard value storage unit 9b as normalization.

In the explanation of the display, the pattern "-" indicates that the position is not adjusted, and that the position is adjustable.

If the adjustment items are displayed when the adjustment amount is displayed, the understanding will be deepened.

[0052]

According to the present invention, the complicated display method according to the conventional adjustment items can be shared by one display method and displayed, and the standard value can be displayed. It is possible to provide an adjustment display that is easy for the viewer to understand.

As described above, by adopting one display method, the program capacity of the microcomputer relating to the adjustment display can be greatly reduced, and it becomes possible to use a cheaper microcomputer, which leads to an inexpensive system. Can be built.
