A second screen appears at. Further, when the switching command is given by the switching command instructing means in the display state of the second screen, the first screen gradually appears from the second position on the second screen.

[0008]

[Embodiment] In this embodiment, as shown in FIG.
Have twenty. Eight audio signals are input to the DSP 20, and the DSP 20 controls the acoustic characteristics, for example, the volume level and the frequency characteristics, in the eight channels provided with these signals, respectively. Then, the controlled signals of the respective channels are mixed into a predetermined state and output as a right signal R and a left signal L.

Each channel is provided with an attenuator, an equalizer, a filter, etc. for adjusting the acoustic characteristics, and these characteristics are controlled based on the acoustic control information supplied from the CPU 22.

The CPU 22 controls each of the sound control information by each operator 24 of an operator unit provided for each channel.
It is generated according to the operation of. Further, the CPU 22 causes the touch display 28 to display the characteristics of the equalizer, the filter, and the like, the frequency characteristics of the input signal and the output signal, and the like via the drive unit 26.

This display instruction is issued to the CPU 22 by the switch unit 30 provided on the touch display 28.
Given according to the operation of.

The touch display 28 can display a parent screen as shown in FIG. 1B and a child screen as shown in FIG. 1E, and the parent screen has a display 32 for each channel name. And an indication 34 of each acoustic characteristic name of an attenuator characteristic, an equalizer characteristic, and a filter characteristic are displayed, and when any one of the channel name indications 32 is touched with a finger, the switch section 30 tells the CPU 22 that When the touched channel name is indicated and one of the characteristic name displays 34 is touched with a finger, the touched characteristic name is C.
In response to the instruction from the PU 20, the CPU 22 causes the touch display 28 to display on the touch display 28 via the drive unit 26, for example.
The child screen as shown in (e) is displayed.

On this child screen, a display showing the selected channel name (two channels in this example) and the selected characteristic (equalizer characteristic in this example) is displayed, and the content of the selected characteristic is specified. Is displayed graphically. Further, a changeover switch display 36 for changing the display from the child screen to the main screen is also displayed. When the switch display 36 is touched with a finger, the switch unit 30 gives a command for switching display to the parent screen to the CPU 22, and the CPU 12 causes the touch display 28 to display the parent screen via the drive unit 26.

When an instruction to switch the display from the parent screen of FIG. 1 (b) to the child screen of FIG. 1 (e) is given, FIG. 1 (c),
As shown in (d), the screen gradually switches from the central portion of the parent screen to the child screen, and finally the entire screen becomes the child screen.

On the contrary, when an instruction to switch the display from the child screen to the parent screen is given, the state shown in FIG. 1 (e) is changed to that shown in FIG. 1 (d).
As shown in (c), the screen gradually switches from the peripheral portion of the child screen to the parent screen, and finally all of the screens are switched to the parent screen.

In order to perform such screen switching, the CP
U22 operates as in the flow chart of FIG. That is, first, a control signal is supplied to the drive unit 26 to display the main screen as shown in FIG. 1B (step S2). Next, it is determined whether the child screen is selected, that is, whether any one of the channel name display 32 and the characteristic name display 34 is touched with a finger (step S4). If not, step S4 is repeated until contact is made. Therefore, the display on the touch display 28 remains the main screen.

When the child screen is selected, the display is gradually switched from the central portion of the screen to the child screen (step S6).
For switching to this child screen, for example, if the screen size is as shown in FIG.
Assuming that the size is 640 × 480 dots as shown in (a), first, as shown in FIG.
The drive unit 26 is provided such that a portion of x48 dots is displayed as a small screen, and when about 50 msec elapses, a portion of 128 × 96 dots becomes a small screen as shown in FIG. The contents of the display memory are rewritten. Similarly, every time 50 msec elapses, the width is 64 dots and the height is 4 dots.
The contents of the display memory are rewritten so that the size of the sub-screen is increased by 8 dots. In this way, it is possible to completely switch to the small screen in about 0.5 seconds.

After such switching to the sub-screen is completed,
Whether the parent screen image has been selected, that is, the changeover switch display 3
It is determined whether 6 is touched with a finger (step S8). If not, step S8 is repeated until contact is made. Therefore, the display of the child screen is maintained.

When the contact is made, the display is gradually switched from the peripheral portion of the child screen to the parent screen (step S).
10). This switching is the reverse of the display switching from the parent screen to the child screen. First, the peripheral 64 × 48 dot portion is displayed on the parent screen, and after about 50 ms, the peripheral 128 × is displayed.
The contents of the display memory in the drive unit 26 are rewritten so that the 96-dot portion becomes the parent screen. Similarly, 50
The display area of the main screen increases from the peripheral portion by 64 × 48 dots every m seconds, and the display screen is completely switched to the main screen after 0.5 seconds. Following this step S10,
Step S4 is executed again.

In the above embodiment, the touch display 2
Although 8 is used, a normal display device and function keys may be used instead. In the above embodiment, when switching from the parent screen to the child screen,
The screen was gradually switched from the central part, and when switching from the child screen to the parent screen, the screen was gradually switched from the peripheral part, but conversely, when switching from the parent screen to the child screen, the screen was switched from the peripheral part. When switching from the screen to the main screen,
You may switch from a central part.

Further, in the above embodiment, the switching between the two screens of the parent and the child has been described, but the present invention is not limited to this, and switching between a plurality of screens of the parent, child, grandchild, etc. can be performed. For example, in the case of an audio mixer device, since each of the above channels is provided in the input channel unit, the group unit, the main unit, etc., the screen for selecting one of these units is used as the parent screen. The screen for selecting the channel and the characteristic shown in (b) may be the sub screen, and the screen for showing the specific acoustic characteristic of the selected channel shown in FIG. 1E may be the grandchild screen.
In this way, when switching to three or more screens, for example, when switching from the parent to the child screen, the screen is switched from a position slightly left of the center of the screen, and when switching from the child screen to the grandchild screen, It may be possible to know which screen is being switched to which screen depending on the position at which the screen switching is started, such as switching from a position slightly to the right of the center.

[0022]

As described above, according to the present invention, when the switching command means gives a switching command to the second screen while the first screen is displayed on the display means, the first screen of the first screen is displayed. The second screen gradually appears from the position of 1. Further, when the switching command is given by the switching command instructing means in the display state of the second screen, the first screen gradually appears from the second position on the second screen. Therefore, without knowing whether each screen is the first screen or the second screen, it is possible to know which screen the display is switched to from the position where the screen appears and perform the switching operation. Even if someone other than the person watching the screen can easily see what kind of screen the screen was switched to, and those who are performing the switching operation will find that the operation they performed is incorrect from the position where the switching screen appears. Whether or not it can be easily determined.
