[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio device capable of processing a video signal and an operation display method thereof.

[0002]

2. Description of the Related Art For example, an audio signal reproduced from a VTR is supplied to an audio device to improve reproduced sound. In this case, a video signal reproduced from the VTR is also supplied to the audio device at the same time, and the audio signal is also supplied from the audio device to a receiver or another VTR. When supplying to another VTR for the purpose of dubbing or the like, processing such as amplification suitable for dubbing the video signal may be performed in the audio device.

On the other hand, in audio equipment, the contents of signal processing have been diversified in recent years. Therefore, for example, it is becoming difficult to display necessary and sufficient processing contents on a small-scale display provided on the operation panel of the device. The present invention has been made in view of these points.

[0004]

A problem to be solved is that it is becoming difficult to sufficiently display, for example, a display provided on an operation panel of a device.

[0005]

According to a first aspect of the present invention, there is provided an operation panel (key switch) in an audio device which is capable of processing an audio signal and having a capability of processing a video signal by connecting a receiver. 13) means for detecting the operated state (microcomputer 12) and means (GDC9) for forming a video signal for displaying an image simulating the operation panel on the receiver are provided. When operating, the audio device is configured to form a video signal in which the display content of the position of the displayed image corresponding to the operation detected on the operation panel is changed.

The second means according to the present invention forms an image simulating the operation panel of the audio device, detects the operated state of the operation panel of the audio device, and detects the operation image of the operation panel of the audio device. It is an operation display method for an audio device, in which an image of an operated portion is changed.

[0007]

According to this, the operated state is displayed on the image simulating the operation panel, and an extremely clear display can be performed.

3: an audio signal reproduced from a device (TAPE2: not shown) on the recording side during dubbing is supplied in stereo. The signal from the input selector switch 1 is a DSP for sound field processing.
The processed signal supplied to the section 4 is taken out to the output terminal 6 through the muting switch 5.

Reference numeral 7 is a video signal input selector switch. Each of the input selector switches 7 has an input terminal 8
For example, 3 systems of video equipment (VIDEO1,
2, 3: video signals reproduced from (not shown) are supplied. A signal from the input changeover switch 7 is supplied to a graphic controller (GDC) 9 which forms a video signal of a display image described later. The signal formed by the GDC 9 and the original signal are selected by the switch 10 and taken out to the output terminal 11.

Further, 12 is a microcomputer for controlling the system. The microcomputer 12 is provided with a processing CPU 21, a ROM 22 and a RAM 23, and controls and the like according to a program written in the ROM 22. Then, for example, a signal from the key switch 13 which constitutes the operation panel is supplied to the microcomputer 12,
In accordance with this signal, the input changeover switches 1 and 7, the tuner unit 2, the DSP unit 4, the GDC 9, and the switches 5 and 10 are controlled. The control status and the like are displayed on the display 14 and the LED 15 on the operation panel.

That is, the operation panel of this apparatus is constructed, for example, as shown in FIG. In the figure, on this operation panel, at least a power switch 51, an LED 52 indicating display on the receiver, and a display 1
4. A dial knob 53 for controlling the volume is provided. Further, the operation panel is provided with an operation unit corresponding to a key switch 31 for performing an operation of muting an audio signal, and an LED 15a indicating that this is operated.

An operation unit corresponding to a key switch 32 for controlling functions such as switching the input changeover switches 1 and 7 is provided. In addition, an operation section corresponding to a key switch 32b for selecting an audio signal to be reproduced by monitor from a recording side device (TAPE2: not shown) at the time of dubbing by the input changeover switch 1 and the operation section thereof are further described. The LED 15b shown is provided.

On the other hand, the graphic controller (GDC) 9 of this apparatus forms a video signal of a display image as shown in FIG. That is, in A of the figure, an image simulating the above-described operation panel is displayed on the left side of the image. The power switch 51, the display 14, the dial knob 53, and the like described above are drawn on an image simulating the operation panel.

Then, in the image simulating the operation panel, when the above-mentioned key switches 31, 32 and the like are operated, the display contents of the position corresponding to the operated key are changed.
For example, it is changed as shown in B of FIG. That is, in the example of the figure, a display painted in bright color is formed at a position corresponding to the key switch 31 for performing the muting operation of the audio signal, and the sound reproduced by the recording-side device (TAPE2) is monitored during dubbing. Key switch 3 to select the signal
A display of a light-colored frame is formed at a position corresponding to 2b.

Further, a display similar to each display is provided on the lower right side of the display image, and a description of the operated contents is displayed together with this display. At the position corresponding to the display 14 of the image simulating the operation panel, for example, the name of the device selected by the input changeover switches 1 and 7 is displayed. Further, in the upper right part of the display image, for example, the content displayed in the display 14 is enlarged and displayed.

In this way, according to the above-mentioned device, the operated state is displayed on the image simulating the operation panel, and the display can be made extremely clear.

FIG. 4 shows a flowchart of the key processing. That is, when the key processing is started in the figure, it is determined in step [1] whether or not the key switch 31 is operated, and in step [2] it is determined whether or not the key switch 32 is operated. If both are no, the process proceeds to the next step. If YES in step [1], the switch 5 is turned off in step [3], and the LED 15 is turned on in step [4]. Further, the switch 10 is switched to the GDC 9 side in step [5], the display data is supplied to the GDC 9 in step [6], and the process proceeds to the next process.

On the other hand, if the answer is YES in step [2], the display processing of the display 14 is performed in step [7], and the input selector switch 1 is switched in step [8]. And step

Switch 9 is GD in [9]
The device name is switched to the C9 side, the connected device name is read from the RAM 23 in step [10], and step [1
In 1], the display data is supplied to the GDC 9 and the process proceeds to the next process. In this way, the above display can be performed.
