The electronic advertising system is also referred to as digital signage, and unlike a poster whose
display content is fixed after printing, the display content can be switched by holding a large
number of display information in a communication means or a built-in storage device. A variety
of video advertisements can be performed such as displaying moving images.
[0003]
An electronic advertisement system generally includes a display device such as a plasma display,
a liquid crystal display, or an LED display, and a control unit such as a video display control unit
and a storage device, and displays moving image and still image information on the display
device. It is supposed to be. The installation site of the electronic advertisement system includes a
wall of a building, a department store, a supermarket, a convenience store, a hotel, a bank, an
airport, a station, and the like.
[0004]
In addition, the electronic advertisement system has been developed every day, and a system that
only displays one-way advertisement detects two-way advertisement, that is, detects
characteristics such as gender and age of the person in front of the display screen. There is
disclosed a technique of controlling image contents to be reproduced on the display screen. In
particular, an image taken by a camera directed to the position of a person watching the screen
(in the following, the term taken image is used to distinguish it from the image displayed on the
display device. Determine the gender and age from the characteristics of the person's face from)
and use the term display image to distinguish it from the image captured by the person with the
determined attribute (in the following, from the image taken by the camera) . The display image
includes a still image and a moving image. Patent Document 1 discloses a display system for
displaying the image on the display device.
[0005]
In the electronic advertisement system, it is often seen that only the display of the image but not
the sound is played, but it is also effective to flow the sound other than the image for the
advertisement. For that purpose, a speaker system for an electronic advertising system is
required.
01-05-2019

[0006]
Electronic advertising systems may display advertisements to people outdoors, but at that time
they need to be able to hear the sounds of people outdoors. Therefore, a speaker must be
provided outdoors. In order to provide a speaker outdoors, it is necessary to make a hole in a
wall of a cable from a power supply unit or the like provided indoors in order to send a power
supply unit or an audio signal to the speaker, and to route the cable through the hole.
[0007]
However, by using a wireless speaker system as disclosed in Patent Document 2, a method of
installing a speaker without opening a hole in a wall or the like is also conceivable.

display content is changed depending on the characteristics of the person who is in front of the
display screen, that is, only one-way advertisement.
However, it has generally been the case that the voice is not changed regardless of whether there
is a particular person or not, and the speaker is operated even when there is no person, and the
voice is made to flow.
Therefore, there is a problem that the voice is sent even though there are no people, and the
efficiency of the advertisement by the voice is poor, and the power is wasted. Also, regardless of
the attribute of the person, the voice is one-sided, so that the voice does not draw the attention of
the person, and one-sided voice will flow, again the efficiency of the advertisement by voice is
poor, the power There was a problem that it became useless. Here, the efficiency of the
advertisement by voice means, for example, the ratio of the time when a person listens to the
advertisement to the time when the advertisement is outputted by voice, or the time when the

The face detection unit 21 executes pattern recognition processing, for example, and detects face
information from captured image data captured by the camera 11. Then, when face information
is detected from the image data, a signal indicating that a face is detected is sent to the control
unit 20. In addition, when a face is detected, the control unit 20 outputs a command to send face
information to the distance estimation unit 22. The face information is sent to the distance
estimation unit 22. For the processing of the face detection unit 21, for example, a method
disclosed in Japanese Patent Application Laid-Open No. 2008-191683 can be used. That is, first,
the central point of the template meaning the template is placed at a certain coordinate point of
the acquired captured image data, and while scanning this central point, the similarity of the
overlapping portion between the template and the captured image data is calculated. Determine
where the similarity is at a maximum. By matching a pattern extracted from photographed image
data of a face with a template including, for example, shapes of eyes and ears, it is possible to
acquire face information such as the position of eyes. Then, there are many methods other than
the method using pattern recognition, such as a method using learning by a neural network or
the like, a method of extracting a portion having a characteristic in a physical shape from a
photographed image region. Here, the pattern recognition is a process of matching (matching)
the extracted pattern with one of predetermined concepts. In addition, template matching is a
method of comparing a photographed image with a template while moving a template that
means a pattern on the photographed image. By this method, physical shapes such as eyes and a
nose are extracted from the photographed image area.
[0036]
The distance estimation unit 22 counts the number of pixels of the eye interval from the face
information sent from the face detection unit 21 and calculates the eye interval by the number of
01-05-2019
13
pixels. Then, the distance from the screen to the face is estimated using a graph showing the
relationship between the eye interval (number of pixels) and the distance obtained in advance.
Information on the estimated distance between the person and the screen is output to the image
selection unit 23 and the speaker system drive unit 106. In addition, since a person wearing
sunglasses and glasses can not obtain the eye interval from the image, in such a case, the
distance can be estimated from the size of the face as described later.
[0037]
The image selection unit 23 stores a table having a correspondence relationship between the
distance and the display image stored in the storage device 14, and using the table, the distance
between the person estimated by the distance estimation unit 22 and the screen Is selected, and
the display image number is output to the control unit 20. The control unit 20 outputs a display
image corresponding to the display image number from the storage unit 14 to the image display
unit 12, and the image display unit 12 displays the display image.
[0038]
The speaker system drive unit 106 sends information on whether or not to set the standby mode
to the speaker system 100 based on the distance information and a signal indicating whether or
not a person from the human sensor 125 (see FIG. 3) is detected.
