Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an audio-compatible image reproducing device used to advertise and introduce a large number of products and the like.

[Prior Art] Conventionally, individual products are displayed on a screen for the purpose of promoting and introducing the products and the like to a large number of unspecified people in the windows of shops and the streets. In this case, it is suggested to divide the screen into multiple parts in order to enhance the advertising effect, display separate products at the divided parts, and replace the displayed products with each other to change the displayed product every moment. Has been done. In addition, this device is often placed in an atmosphere where music is played in order to enhance the advertising effect.

[Problems to be Solved by the Invention] However, in such a device, the operator operates the operation panel to select an image. There is a problem that they do not necessarily match and give a feeling of strangeness.

[Means for Solving the Problem] In order to solve such a problem, the present invention provides a monitor capable of displaying a screen divided into a predetermined area and a screen having a number larger than the number of divided display areas of the monitor. An image storage unit for storing, a threshold level setting unit for outputting a signal having a predetermined threshold level or more among the audio signals that have passed through the filter as a trigger signal, and a predetermined threshold value, and a trigger level setting unit. It is provided with a control circuit for reading out a different image from the image storage section each time a signal is supplied, and a multi-display section for displaying the read-out image in a predetermined divided area of the monitor.

[Operation] A plurality of products are displayed on the screen, and one of the displays is switched every time the frequency band or level of the audio signal changes.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is an audiovisual device such as a video tape recorder or a laser disk, 2 is an audio pulse generator for converting an audio frequency component into a pulse, 3 is a signal generated from the audiovisual device 1 is written in an image storage section, A control circuit 4 for controlling the reading of written data, an image storage unit 4 for storing, for example, 32 images of the audiovisual equipment 1, and a control circuit 3 for controlling a plurality of images (as will be described later in this embodiment). It is a multi-display unit for displaying the image of 9) on the monitor 6.

As shown in the figure, the voice pulse generator 2 is high / medium / high.
A filter unit 201 having three types of low filters, each of which can be manually switched, a threshold level setting unit 202 of manually switching three types of high, medium, and low threshold levels, and waveform shaping It is composed of a section 203. The multi-display unit 5 in the figure has a screen division mode for dividing the screen of the monitor 6 into a plurality of screens, and in this embodiment, it is set to nine divisions.

The operation of the device configured as described above is as follows. The audiovisual device 1 generates an image signal representing a product and an audio signal matching the image of the product. The audio signal is supplied to the audio pulse generator 2,
If the set frequency band is set in the internal filter unit 201, that is, the high frequency band in this embodiment, the signal in that band is extracted by the filter. The audio signal thus taken out is sent to the threshold level setting unit 202. As described above, this circuit is configured to select three types of levels of high, medium, and low. For example, when a high level is set, only the signal above that level is set to the threshold level setting section. It is going to pass 202.

The signal that has passed through the threshold level setting unit 202 is supplied to the control circuit 3 via the waveform shaping unit 203. This signal is supplied to the image storage unit 4 and used as a trigger signal for writing the image signal from the audiovisual device 1 into the image storage unit 4. Every time a trigger signal supplied from the control circuit 3, that is, a write signal is generated,
The image from the audiovisual device 1 is the image storage unit 4.
Memorized in. After the voice trigger signal is input,
During processing in the control circuit, the image and the trigger signal are synchronized because they are latched by the synchronization signal.

In this device, the image storage unit 4 has an image storage capacity for 32 images. In this example, the signal thus stored corresponds to the high frequency band of the audio signal and also corresponds to the high threshold level portion.

After the storage is completed in this way, the plurality of images stored in the image signal storage unit 4 are displayed on the monitor 6 under the control of the control circuit 4. In this case as well, the sound pulse generator The second filter unit 201 and the threshold level setting unit 202 are set to a high frequency band and a high threshold level, respectively. In this case, the audio signal from the audiovisual device 1 is supplied to the audio pulse generator 2 and the output signal is generated only for the signal in the high frequency band corresponding to the loud sound.

This output signal is supplied to the control circuit 3, reads the image stored in the image storage unit 4, and supplies it to the multi-display unit 5. The multi-display unit 5 displays the signals read from the image storage unit 4 at predetermined locations on a screen divided into nine parts. When the trigger signals are generated one after another, the image signals read out in response to the trigger signals are displayed one after another at the remaining 9 divided areas. Various images will be displayed on all parts of the screen divided into 9 parts, but since audio signals are supplied one after another, image signals from the image storage part are read out one after another and supplied to the multi-display part 5. To be done. The multi-display unit 5 can select whether to allocate the supplied signal to the 9-divided parts according to a certain rule or to allocate them randomly. In this case, if you select a function that is randomly assigned, each time the frequency or level of the audio signal changes,
One of the nine divided screens is randomly replaced. In addition,
The image signal from the audiovisual device is supplied to the image storage unit 4 even during reproduction, but if 32 images are written in the image storage unit 4, the image can be written until the power is turned off. If it is not set, the operation will not be hindered. An audio signal is supplied from the audiovisual supply 1 to the monitor 6 through a signal line connected to the monitor 6, which has a speaker inside the monitor 6 and can be used for both sound and picture. This is because it is possible to monitor.

Although the above embodiments describe high frequency bands and high threshold levels, different screens can be changed by changing the frequency band and the threshold levels. , A screen with a change can be obtained in synchronization with music. In addition, the audio signal from the audiovisual equipment is assumed to be music in which wide, middle, and low frequency bands and high, medium, and low voltage are mixed irregularly. It may be a signal to perform. Further, the image storage unit 4 stores the image signal from the audiovisual device,
The signal stored in M or the like may be read out.

As described above, according to the present invention, the trigger signal is generated according to the change of the audio signal, and the image signal is read by the trigger signal. Therefore, the screen changes in synchronization with the audio signal. As a result, there is an effect that a screen that does not cause discomfort and that is interesting can be obtained.
