Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for use with a processing device for processing according to the operation of an operator.
The present invention relates to a display switching device that switches the display according to the operation of an operator.

[0002]

2. Description of the Related Art Conventionally, for example, there is a digital audio mixer as a device provided with the above display switching device. The digital audio mixer has a plurality of channels to which digital audio signals are respectively input, and after each channel is subjected to attenuation processing, equalizer processing, filter processing, etc., the signals of each channel are mixed.

It is sometimes necessary to confirm what characteristics each of the above-described processes in each channel has. In such a case, for example, when the digital audio mixer is equipped with a touch display, each channel name, each processing name and confirmation display are displayed on the touch display, and the channel name to be confirmed is indicated. Touch, touch the name of the process you want to confirm, and then touch the confirmation display with your finger to switch the touch display screen from the display of the channel name, etc., and specify the specified channel. The characteristics of the processed process are displayed.

[0004]

However, in the digital audio mixer as described above, after the confirmation display is operated, the CPU, DSP, etc. included in the digital audio mixer perform various calculations and data processing. , Create the screen data required to display the characteristics of the specified process on the specified channel, and at the end of creation, specify the specified process on the specified channel based on this screen data Display the characteristics of. Therefore, it takes time from the operation of the confirmation display until the screen display is switched, and it may take about 1 second when the screen is 640 × 480 dots, for example. During this time, the operator cannot recognize whether the digital audio mixer is out of order or is operating normally.

During this period, "WORKING" and "WAI" are displayed on the screen to indicate that the screen is currently being processed.
By displaying a message composed of characters such as "T", it is possible to make the operator recognize that it is operating normally. However, for example, such a CPU or DSP
If the operation method is wrong in the device using (for example, in the above example, after operating the channel name display, forgetting to operate the process name and operating the confirmation display)
A message such as “ERROR” may be displayed on the screen. In such a case, after the operation is completed, the operator
Is it a display such as "WORKING"? "ERROR"
It is necessary to identify whether it is a display.

[0006] Since all of these messages are displayed in characters, "WORKIN"
Only a person skilled to some extent can discriminate between the "G" display and the "ERROR" display in an instant. In a situation in which various operations must be performed one after another while a play or the like is in progress, it is a considerable burden on the operator to perform such identification instantaneously.

Further, when displaying a message using characters, which language to use becomes a problem. This is because the operator may not understand some languages. For example, the digital audio mixer must be configured so that it is displayed in Japanese in the case of domestic specifications and in English in the case of the United States specifications, which increases the burden of manufacturing control.

It is an object of the present invention to allow an operator to instantly understand that a device is operating normally without increasing the burden of manufacturing control.

[0009]

In order to achieve the above object, the first aspect of the present invention provides an operator, a processing means for performing processing according to the operation of the operator, and a screen provided with a plurality of dots. Selected from the first display data associated with the operation of the operator and the second display data associated with the processing result of the processing means are supplied to the respective dots, Display means for displaying a display corresponding to display data on the screen, and first display data for displaying the first display data on the screen of the display means in a non-operation state of the manipulator, and a second display at the end of the processing by the processing means. Display control means for displaying display data on the screen of the display means, wherein the display control means transforms the first display data from a time when the operator is operated until a time when the processing means finishes processing. Is to have.

The second aspect of the present invention is the same as the first aspect of the present invention.
The first display data transforming means changes the value of the first display data supplied to a specific dot among the respective dots of the display means to another value.

The third aspect of the present invention is the same as the first aspect of the present invention.
The first display data transformation means changes the value of the first display data so as to change the brightness of the screen of the display means.

[0012]

According to the first aspect of the present invention, when the operator is operated while the display control means is displaying the first display data on the display means, the processing means responds to the operation of the operator. Perform processing. At the same time, the first display data transformation means of the display control means transforms the first display data. As a modification of this display data, as in the second invention, the value of the first display data supplied to a specific dot of each dot of the display means is changed to another value, or the third value.
There is a method in which the value of the first display data is changed so as to change the brightness of the screen of the display means. Such data change is performed until the processing means completes the processing. In this way, since the data displayed on the display means based on the first display data is transformed, the operator can recognize that the device is operating normally, and since it is not a display in characters, It is not necessary to instantly identify whether the display indicates an erroneous operation or the display indicates that the device is operating normally. Then, when the processing by the processing means is completed, the display on the display means is based on the second display data obtained by the processing result by the processing means.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, the present invention is applied to a digital audio mixer, and as shown in FIG. 3, it has a plurality of channels, for example, eight channels of first to eighth channels. Digital audio signal from a DSP (digital signal processor)
2 is supplied.

The DSP 2 follows the instruction from the CPU 4,
The characteristics of the digital audio signal of each channel are adjusted, for example, the attenuation amount is adjusted, the equalizer is adjusted, the filter is adjusted, and mixing is performed, and the mixed audio is output from a plurality of output channels, for example, two channels R and L.

The CPU 4 gives an instruction to the DSP 2 according to the operation of the touch display 6. The touch display 6 is, for example, a color touch display. For example, in order to confirm how the characteristics of the audio signal in each channel are set, first, an initial screen as shown in FIG. 1A is displayed. .

On this screen, channel name displays 8-1 to 8-8 are displayed at the left end along the vertical direction. Further, in the center, there are three processing displays along the vertical direction, for example, an attenuation amount display 10-1, an equalizer display 10
-2, the filter display 10-3 is displayed. Also,
The confirmation display 12 is displayed on the upper right of the screen.

In order to perform these displays, the touch display 6 has a large number of dots vertically and horizontally, for example, 640 × 480.
Dots are provided, and the first display data for causing these dots to emit light is supplied from the CPU 4. The CPU 4 has R, G, B corresponding to the above dots.
Video RAMs for three colors are provided, and the first display data is stored in these video RAMs. Therefore,
The CPU 4 functions as a display control unit, and the touch display 6 functions as a display unit.

Further, on the touch display 6, for example, contact type or optical type detecting means is provided, and any one of the above-mentioned displays 8-1 to 8-8, 10-1 to 10-3 and 12 is provided. When the operator's finger comes into contact with, the contact is detected and the CPU 4 is notified. Therefore, the touch display 6 also functions as an operator.

For example, in FIG. 1A, the operator
When the finger is brought into contact with the channel name display 8-2 corresponding to the channel 2, the finger is brought into contact with the equalizer display 10-2, and finally the finger is brought into contact with the confirmation display 12, the CPU 4
Instructs the DSP 2 to send data regarding the frequency characteristics of the equalizer of channel 2, and when this data is sent, creates second display data for displaying this on the touch display 6, After the creation, it is stored in each video RAM, and the frequency characteristic of the equalizer of channel 2 is displayed on the touch display 6 as shown in FIG. Therefore, the CPU 4 also functions as a processing unit.

As described in the section of the prior art, a certain period of time is required from the operation of the confirmation display 12 to the display as shown in FIG. 1C, and the display is made. Until then, the operator cannot recognize whether the digital audio mixer is operating normally. Therefore, in this embodiment, when the confirmation display 12 is operated, the first display data stored in each video RAM is immediately displayed on the first display data shown in FIG.
The scattered data is overwritten as shown in (b).

The overwriting of the scattered data is, for example, 1
For example, every other dot, or every two or three dots, the same value data is written every few dots compared to the total number of dots. In FIG. 1B, each dot is drawn in a considerably large size in order to simplify the drawing. This overwriting may be performed on all of the R, G, and B video RAMs, or a specific one or two video R
You may go to AM.

As a result, the display on the touch display 6 becomes a partially deformed screen as shown in FIG. 1A, and the operator does not have to read characters one by one,
You can instantly understand that the digital audio mixer is operating normally. Moreover, since this overwriting is performed in a scattered manner, it is not necessary to rewrite the data corresponding to all the dots, and the time required for rewriting is shorter than the case of rewriting the data for all the dots. Moreover, since it is not necessary to create character data, the time required from the operation of the fixed display 12 to the deformation of the display is very short. Note that the data may be overwritten in a grid pattern as shown in FIG. 2 instead of the scattered dot pattern. Alternatively, a specific area of the initial screen, for example, a rectangular area defined near the center of the screen may be overwritten so as to have a specific color, for example, red. Since the CPU 4 transforms the first display data in this way, the CPU 4 corresponds to the transforming means.

While the first display data is deformed and displayed in this way, the CPU 4 creates the second display data and writes it in each video RAM. As a result, a screen as shown in FIG. 1C is displayed on the touch display 6.

FIG. 4 is a flowchart showing the processing performed by the CPU 4 to switch the screen display in this way. In this process, first, when the initial screen selection display (not shown) on the touch display 6 is operated, the fact that the initial screen is selected is displayed on the touch display 6 by the CP.
The U4 is notified (step S2) and the screen data for the selected screen (in this case, the screen data for displaying the initial screen as shown in FIG. 1A (first display data))
Is created by the CPU 4 (step S4). Then, this is sent to the touch display 6 to display the selected screen (in this case, the initial screen) (step S6).

Next, it is determined whether the next screen is selected (step S8). For example, in the state where the initial screen is displayed, it is determined whether the operator's finger touches any of the channel name display, the attenuation, equalizer, and filter displays and the final display on the initial screen. If the next screen is not selected, step S8 is repeated until it is selected.

When the next screen is selected, the scattered data as shown in FIG. 1B is overwritten in the video RAM and the scattered pattern is overwritten and displayed on the current screen (step S1).
0). Following this, step S4 is executed again, but at this time, in step S4, since the next screen was selected in step S8, the second screen for displaying as shown in FIG. 1C is displayed. Create display data for. Until the creation of this display data is completed, the display on the touch display 6 remains the dot pattern overwritten on the initial screen. When this second display data is created, step S6 is executed and the display is switched to that shown in FIG. 1 (c).

Although not shown in FIG. 1 (c),
When the finger touches the return display for returning to the display of the initial screen from such a display and the next screen is selected, step S8 is performed, and step S10 is executed.
The dot pattern is overwritten on the display as shown in FIG. 1C, step S4 is executed, and the first display data is created for the initial screen display.

In the above embodiment, the display screen is as shown in FIG.
The case of switching from the initial screen as shown in (a) to the secondary screen as shown in (c) of the figure has been described. For example, from the secondary screen to a tertiary screen in which the frequency characteristics of the secondary screen are numerically represented. It is also possible to switch the display, and even in the case of switching from the secondary screen to the tertiary screen, the scattered pattern can be overwritten on the secondary screen.

Further, in the above embodiment, a part of the first display data is changed to other data by overwriting the scattered pattern on the initial screen, but the fixed display is touched by the finger. When this is done, the screen contrast may be changed to indicate that the digital audio mixer is operating normally.

For example, as a contrast change, if the contrast is to be made lower than before, the following can be done. Generally, when a color of a certain dot on a color screen is set as a desired color, the dot is red (R), green (G),
It is constructed by three primary colors of blue (B) and the brightness of each of R, G and B is adjusted. Given hue H (0 ≦ H ≦ 360), lightness L (0 ≦ L ≦ 1), and saturation S (0 ≦ S ≦ 1) as factors of the color of a certain dot, these hue H and lightness L are given. It is known that the R, G, and B luminance components may be set as follows in order to combine the colors represented by the saturation S.

That is, when S = 0, R, G, and B are expressed by the formula 1
It is represented by.

[0032]

[Equation 1] [R, G, B] = [L, L, L] ... (1)

When S ≠ 0, R, G, and B are values represented by equations 2, 3, and 4, respectively.

[0034]

[Equation 2] R = F [H + 120, M1, M2] ... (2)

[Equation 3] G = F [H, M1, M2] ... (3)

[Equation 4] B = F [H-120, M1, M2] ... (4)

However, M2 included in equations 2, 3 and 4
Is expressed by Expression 5 when L ≦ 0.5, and expressed by Expression 6 when L <0.5.

[Equation 5] M2 = L * (1 + S) ... (5)

[Equation 6] M2 = L * (1-S) ... (6)

Similarly, M1 included in equations 2, 3 and 4
Is expressed by Equation 7.

[Equation 7] M1 = 2 * L-M2 ... (7)

Further, F [H, M1, M2] is 0 ≦ H
When <60, it is represented by Equation 8, when 60 ≦ H <180, it is represented by Equation 9, when 180 ≦ H <240, it is represented by Equation 10, and when 240 ≦ H <360, it is represented by Equation 11.

## EQU00008 ## F [H, M1, M2] = M1 + (M2-M1) * (H / 60) ... (8)

[Equation 9] F [H, M1, M2] = M2 ... (9)

[Equation 10] F [H, M1, M2] = M1 + (M2-M1) * (240-H) / 60 (10)

[Equation 11] F [H, M1, M2] = M1 ... (11)

The values of R, G and B for synthesizing the color of a certain dot in this way are functions of the lightness L and the saturation S. Therefore, for example, in the initial screen, the brightness of each R, G, and B is changed by reducing the value of L included in R, G, and B that combines the colors of the dots from a value different from the original value. By doing so, you can reduce the contrast more than ever.

Alternatively, R, G, which combine the colors of the dots,
The contrast can be lowered by reducing the value of S contained in B from the original value and changing the brightness of each of R, G, and B.

Instead of lowering the contrast, it is possible to increase the contrast, or for example, to contrast only a specific area of the initial screen with a contrast different from other areas.

In the above embodiment, the touch display is used as the manipulator and display means, but a normal display such as a CRT and a normal manipulator such as a keyboard may be used. Also, in the above example,
The present invention has been implemented in a digital audio mixer,
The present invention is not limited to this, and can be implemented in other devices as long as the device maintains the current state of the display while the processing means is performing the processing.

[0042]

As described above, according to the first aspect of the present invention,
While the processing means is creating the second display data in accordance with the operation of the operator, since the data obtained by transforming the first display data is displayed on the display means, the operator displays a message such as characters. There is no need to read and you can instantly understand that this device is working properly. Moreover, when the display is modified such that a part of the first display data is modified as in the second invention, it is not necessary to modify all the data. Switching from the display based on the first display data to the display based on the first display data can be instantaneously performed, and it can be instantly understood that the normal operation is performed. Further, in the first aspect of the present invention, since characters are not used to indicate that the device is operating normally, it is not necessary to make specifications according to the shipping destination country regardless of which country the product is shipped. Manufacturing control becomes easy.
