The graphic equalizer display 153 will be described. A plurality of slide volume displays 200, 200, 200,... Are displayed corresponding to each frequency. Designate the knob display 201 displayed on the slide volume display 200, and
By raising and lowering the slide groove display 202, boost / cut for the corresponding frequency band can be performed. As described above, the slide groove display 202 corresponds to each frequency band of the equalizer.

For example, the position of the knob display 201 is pressed with the input pen, and the slide groove display 202 is traced up and down without stopping the pressing. The knob display 201 is fixed at the position where the pressing on the touch panel is stopped, and the boost / cut value for that frequency is determined.

In the graphic equalizer display 153 according to the present invention, the value of boost / cut can also be set by crossing the slide groove display 202. For example, the user presses the graphic equalizer display 153 with an input pen, and without stopping the pressing, from the right or left side of the slide groove display 202, the frequency at which the boost / cut value is to be set and the boost / cut to be set.
Trace the panel towards the cut value. The knob display 201 moves to the intersection of the pressing locus and the slide groove display 202, and the boost / cut value of the frequency corresponding to the slide volume display 200 (slide groove display 202) is a value corresponding to the position of the knob display 201. Is set to

According to this setting method, the boost / cut of a plurality of frequency bands can be set independently and continuously. For example, as shown in an example of a frequency characteristic curve a in FIG. 6, consider a case where the frequency characteristics of a reproduced sound are slightly cut in a low frequency range and gently boosted in a high frequency range.

In the graphic equalizer display 153, the user touches the touch panel with, for example, an input pen, and traces the graphic equalizer display 153 while traversing the slide groove display 202 corresponding to the frequency band in accordance with the frequency characteristic curve to be set. In this example,
The graphic equalizer display 153 is traced according to the image of the curve a in FIG. 6, and the locus of pressing is drawn. In each of the frequency bands, the knob display 201 moves to a point where the locus of pressing and the slide groove display 202 intersect. When the input pen is released from the touch panel and the pressing is stopped, the setting of the equalizer is determined.

FIG. 7 shows an example of the graphic equalizer display 153 set as described above. The slide knob 20 of each slide volume display 200, 200,... Follows the locus of the graphic equalizer display 153 traced by the image of the frequency characteristic curve a in FIG.
Are displayed.

As shown by the frequency characteristic curve b in FIG. 6, when it is desired to locally change the characteristic, the above-described slide knob 201 corresponding to the corresponding frequency is directly moved without using this method. It is preferable to use the specified method.

FIG. 8 is a flowchart showing a process for controlling the graphic equalizer circuit 4 of the audio device main body 1 by the graphic equalizer display 153. First, the commander 100 requests the audio device body 1 for the current setting value of the frequency characteristic curve of the graphic equalizer in the equalizer circuit 4 (step S1). Transmission / reception unit 1 of commander 100
An infrared signal for instructing this request is transmitted from 07 to the transmission / reception unit (photodetector 18) of the audio device body 1.

In order to enter step S1, for example, the power of the commander 100 is turned on, the commander 100 is released from the sleep state, and the function selecting section 1 of the commander 100 is operated.
An operation of designating “REFRESH” arranged at 50 can be used as a trigger. Commander 100
In, pressing an arbitrary position of the graphic equalizer display 153 may be used as a trigger.

When the infrared signal transmitted from the commander 100 is received in the audio equipment main body 1, the processing shifts to step S2. Step S2 is a process in the audio device main body 1, and the received signal is decoded by the decoder 19 and supplied to the equalizer control unit 14. Based on this signal, the equalizer control unit 14
The current setting value of the frequency characteristic curve set in the equalizer circuit 4 is output. The output setting value is encoded by the encoder 16, converted into an infrared signal by the light emitting element 17, and transmitted.

The transmitted infrared signal is transmitted to step S3.
Then, it is received by the transmission / reception unit 107 of the commander 100. The received signal is decoded by the decoder 29 and supplied to the commander side control unit 20.

The commander side controller 20 generates a display control signal based on the received and decoded signal. This display control signal is supplied to the display control unit 22. Based on the control of the display control unit 22, the display of the graphic equalizer display 153 on the display unit 23 is a display reflecting the current setting value of the equalizer circuit 4 of the audio device main body 1 (step S4).

In the next steps S5 to S9, the touch panel is pressed, and the frequency characteristic curve in the graphic equalizer display 153 is set as described above.

That is, in step S6, it is determined whether the input value formed as the locus of pressing has passed on the slide groove display 202, that is, on the band axis of the corresponding frequency band. If it has passed, in step S7,
The value in the slide volume display 200 at the time of passing is stored as the boost / cut level of the corresponding frequency band. In the next step S8, the slide volume display 200 corresponding to the passed frequency band is updated based on the set value. Then, in step S9,
It is determined whether or not the pressing on the touch panel is continued. If it has been continued, the process returns to step S5. If it is determined in step S6 that the input value has not passed on the band axis, the process directly proceeds to step S9.

As described above, steps S6 to S9
It is determined whether or not the locus of the touch on the touch panel has passed the slide groove displays 202, 202,... Corresponding to the frequency band axis. Then, a slide volume display 20 corresponding to the frequency band determined to have passed
Are sequentially updated as they pass, and slide knobs 201, 201,... Are displayed at the intersections of the slide groove displays 202, 202,.

If it is determined that the pressing on the touch panel is stopped and the setting of the graphic equalizer is completed, the process proceeds to step S10. In step S10,
The final setting value of each frequency band is transmitted from the commander 100 to the audio device main body 1. Then, in step S11, this signal is received by the audio equipment main body 1, decoded by the decoder 19, and
Supplied to The equalizer control unit 14 determines the characteristics of the equalizer circuit 4 based on the supplied signal,
Control is performed so that the frequency characteristic curve set at 00 is obtained. At the same time, for example, the graphic equalizer display on the main body side operation unit 15 is updated, and the graphic equalizer display 153 on the commander 100 is reflected.

In the above description, the target set by continuously pressing and tracing the touch panel is the graphic equalizer. However, the present invention is not limited to this example. The present invention can be applied to other setting devices having a large number of adjustment points for continuously setting.

For example, according to this setting method, the amplifier 1
The input / output characteristics of 2L and 12R can be set.
FIG. 9 shows an example of setting the input / output characteristics. By setting such as the characteristic c, the dynamic range can be apparently expanded. In addition, the dynamic range can be apparently compressed by setting such as the characteristic d.

For such a setting, a display similar to the above-described graphic equalizer display 153 can be provided. In this case, each slide volume display 200,
.. Correspond to each level in the input characteristic. Input level control is performed linearly between adjacent input level settings. This example is suitable for use in a car stereo, for example.

[0068]

As described above, according to the present invention, by tracing the display of the graphic equalizer in accordance with the image of the frequency characteristic curve, the frequency characteristics of the graphic equalizer corresponding to the traced trajectory are realized. Therefore, it is not necessary to adjust each adjustment point of the graphic equalizer one by one. Therefore, there is an effect that the rough setting of the frequency characteristic to be realized by the graphic equalizer can be performed very easily.

Even when the present invention is applied to setting of other acoustic characteristics, for example, input / output characteristics, there is an effect that desired settings can be easily realized only by tracing the setting screen in accordance with the image of the characteristic curve.
