DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, as shown in FIG.
It has ten. Six audio signals are respectively input to the DSP 10, and the DSP 10 controls acoustic characteristics, for example, a volume level and a frequency characteristic of each of the six channels provided therein. Then, the controlled signals of the respective channels are mixed in a predetermined state and output as a right signal R and a left signal L.

Each channel is provided with an equalizer, a filter, and the like in order to adjust acoustic characteristics, and these characteristics are controlled based on acoustic control information supplied from the CPU 12.

The CPU 12 stores the sound control information in each operation unit 14 of an operation unit provided for each channel.
Generated according to the operation of. Further, the CPU 12 causes the display device 18 to display characteristics of an equalizer, a filter, and the like, frequency characteristics of an input signal and an output signal, and the like via the display driving device 16.

The display instruction is given to the CPU 12 in response to the operation of the function selection switch 20 and the channel selection switch 22. The function selection switch 20 includes various functions to be displayed, such as a frequency characteristic of an equalizer, a frequency characteristic of a filter, a frequency characteristic of an input signal,
It is provided corresponding to the frequency characteristics of the output signal and the like, and an instruction of the operated function is given to the CPU 12. Also,
The channel selection switches 20 are provided corresponding to the respective channels, and an instruction of the operated channel is given to the CPU 12. The CPU 12 supplies an instruction to display the function selected by the function selection switch 20 on the channel selected by the channel selection switch 22 to the display driving device 16.

While a certain function of a certain channel, for example, an equalizer characteristic is displayed on the display device 18, there is a case where it is desired to display the same function of another channel, for example, the equalizer characteristic. In such a case, if one channel is selected as another channel, for example, FIG.
(B) are shown as screen representing a channel equalizer characteristics from the lower left corner of the screen gradually appears while sliding. When two channels are selected as other channels, a two-channel equalizer characteristic screen appears while gradually sliding from the left side of the screen as shown in FIG. 1C. When three channels are selected, as shown in FIG. 1D, an equalizer characteristic screen of three channels appears from the upper left corner while gradually sliding.

When four channels are selected as other channels, as shown in FIG. 1 (e), a four-channel equalizer characteristic screen appears while gradually sliding from the upper right corner of the screen. When 5 channels are selected,
While gradually sliding from the right side of the screen as shown in FIG. 1F, a five-channel equalizer characteristic screen appears. When six channels are selected, as shown in FIG. 1 (g), equalizer characteristics of six channels from the lower right corner of the screen.
The screen appears, sliding gradually.

It is possible to know which channel has begun to be displayed from the appearing position. The time from the start of the slide to the end of the slide completely is, for example, 300 m
Seconds have been selected.

There is also a case where another function is desired to be displayed on the same channel. For example, there is a case where it is desired to switch from displaying the equalizer characteristics of a certain channel to displaying the filter characteristics. In such a case, when a switch corresponding to a function to be newly displayed in the function selection switch 20 is operated, a function newly displayed from the bottom of the screen, for example, a filter characteristic screen , as shown in FIG. Appears while sliding. As described above, since the slide is performed from a different direction from the case where the channel is switched, it is immediately recognized that the function is switched for the same channel.

As a method of sliding, for example, as shown in FIG. 2 (a), a new screen a gradually slides upward from the bottom of the frame b of the screen, and the previous screen c is gradually moved. Or a new screen a
A new screen a may be displayed so that the previous screen c overlapping the entire surface of the image is turned over. Also in this case, the time from the start of the slide to the end of the slide completely is selected to be, for example, 300 ms. In addition, since the technique for sliding is well-known, detailed description is omitted.

In order to make the display as described above, a CPU
12 performs an operation as shown in the flowchart of FIG. That is, first, it is determined whether the function selection switch 20 has been pressed (step S2). If pressed (step S
2 is YES), the screen of the selected function is slid and displayed as shown in FIG. 2A or 2B (step S4), and the process returns to step S2.

In step S2, the function selection switch 2
If it is determined that 0 has not been pressed (No in step S2), it is determined whether the channel selection switch 22 has been pressed (step S6). If not pressed (step S
6 is NO), and the process returns to step S2.

If the channel selection switch 22 has been pressed (YES in step S6), it is determined whether channel 1 has been selected (step S8). If channel 1 is selected, the screen of channel 1 is slid from the lower left corner as shown in FIG. 1B (step S10), and the process returns to step S2.

If channel 1 is not selected (step S8 is NO), it is determined whether channel 2 is selected (step S12). When channel 2 is selected, the screen of channel 2 is slid from the left side to be displayed as shown in FIG. 1C (step S14), and the process returns to step S2.

If channel 2 has not been selected (step S8 is NO), it is determined whether channel 3 has been selected (step S16). When the channel 3 is selected, the screen of the channel 3 is slid from the upper left corner and displayed as shown in FIG. 1D (step S18),
It returns to step S2.

If channel 3 has not been selected (step S16: NO), it is determined whether channel 4 has been selected (step S20). If channel 4 is selected, the screen of channel 4 is slid from the upper right corner and displayed as shown in FIG. 1 (e) (step S2).
2) Return to step S2.

If channel 4 is not selected (step S20 is NO), it is determined whether channel 5 is selected (step S24). When channel 5 is selected, the screen of channel 5 is slid from the right side and displayed as shown in FIG. 1 (f) (step S26),
It returns to step S2.

If channel 5 has not been selected (step S24: NO), it is determined whether channel 6 has been selected (step S28). When the channel 6 is selected, the screen of the channel 5 is slid from the lower right corner and displayed as shown in FIG. 1 (g) (step S3).
0), and return to step S2. If the channel 6 has not been selected, the process returns to step S2.

In the above embodiment, the sliding direction of all the channels is made different, but the sliding direction may be changed for each channel group. For example, when the operation units of channels 1 to 3 are on the left side of the display device as shown in FIG. 4, when these channels are selected, they are slid from the left, and the operation units of channels 4 to 6 are displayed. If they are on the right side of the device, they may slide from the right when these channels are selected.

When the number of channels is a multiple of 6, for example, 12 channels, channels 1 to 6 are displayed as shown in FIGS. 1B to 1G, and channels 7 to 12 are displayed. May be displayed as shown in FIGS. 1B to 1G. Further, in the above-described embodiment, the present invention is applied to an audio mixer device. However, the present invention is not necessarily limited to this, and has a plurality of functions to be displayed. The present invention can be applied to any provided device.
