Abstract

PROBLEM TO BE SOLVED: To provide an image display method capable of selectively displaying image information composed of still images or moving images, especially advertisement information, depending on presence/absence of a person. SOLUTION: A plurality of monitor sets 102a-102n for which one monitor 2a-2n and one sensor 1a-1n are one set are included and one piece of the image information to be displayed is set for each monitor set 102a-102n. When a detection signal indicating the presence of a person is outputted from a specified sensor 1a-1n, the image information is selectively displayed on the monitor 2a-2n constituting a set with the sensor 1a-1n. When the detection signal indicating the absence of a person is outputted, display of the image information on the monitor 2a-2n is selectively stopped. In the meantime, the image information to be displayed is circulated among the respective monitor sets 102a-102n every time a fixed period elapses or at every fixed number of times of display.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving body sensing image display system and a moving body sensing image display method, and more particularly, to a moving body sensing image display system for displaying image information consisting of a still image or a moving image, particularly advertisement information. The present invention relates to a moving object detection image display method.

2. Description of the Related Art Conventionally, in places where people gather, a monitor is provided on a wall surface of a building or a wall surface of a room to display a still image or a moving image, and advertisement information is sent. It can attract more people's attention compared to the case where posters are pasted on the wall, etc., and although it costs money, the advertising effect is outstanding.

However, in a place where people always come and go, it is effective to always display an image, but it is useless to always display an image where people come and go. The present invention has been made in view of the above circumstances, and a moving body sensing image display system and a moving body sensing image display system capable of selectively displaying image information composed of a still image or a moving image, particularly advertisement information depending on the presence or absence of a person. It is intended to provide a way.

In order to solve the above problems, in the moving object sensing image display method of the present invention, one sensor for detecting the presence or absence of a person and image information consisting of a still image or a moving image are displayed. There are multiple monitor sets, one monitor and one monitor.When a person is near the corresponding monitor from one or more sensors, the image information is selectively displayed on that monitor and the image information is displayed. When there is no one near the monitor that was displaying, the display of image information on that monitor is selectively stopped. As a result, image information can be displayed without waste even when people come and go, only when there are people.
By the way, even if the image information can be displayed only when there is a person, the effectiveness of the advertisement information varies depending on whether the person is near or far from the monitor. According to the present invention, a plurality of monitor sets are provided at the same place, and the image information is selectively displayed on the monitor only when the detection signal indicating that a person is near the monitor is output from one or more sensors. is doing. Therefore, it is possible to display more effective advertisement information or the like for only individuals close to the monitor. The motion detection image display system that performs such a motion detection image display method is particularly suitable for installation in a public toilet, a toilet in a store where many people gather, or the like. According to the present invention, the image information to be displayed is further circulated among the plurality of monitor sets every time a certain period of time elapses or every certain number of display times. Therefore, even if there is a deviation in the number of times of display depending on the installation location of the monitor set, the number of times of display is averaged for all the image information, so that unfairness due to the installation location of the monitor set can be eliminated. In addition, in order to solve the above problems,
In the moving object sensing image display system of the present invention, in addition to a plurality of monitor sets each including one monitor and one sensor, an image information supply means for supplying image information composed of a still image or a moving image. When the sensor receives a detection signal indicating that there is a person near the monitor, the image information supplying means outputs the image information to selectively deliver the image information to the monitor informing the presence of the person, and And an image distribution control means for selectively stopping the distribution of the image information to the monitor when a detection signal indicating that there is no person near the corresponding monitor is received from the sensor informing that the monitor is present. As a result, it is possible not only to display the image on the monitor without waste only when there is a person, but also to display more effective advertisement information or the like targeting only individuals close to the monitor. . Further, by providing one image information supply unit for each monitor set, different image information such as advertisement information of different customers can be selectively displayed for each set. Further, even when one image information supply means is installed for a plurality of monitor sets, a central processing unit (CPU) is provided, and a hub or other physical line connection capable of parallel processing without data congestion is provided. By providing a control means or by performing line connection control by software, it is possible to perform multitask processing and display the same image information on a plurality of monitor sets selected from all monitor sets at the same time. Of course, it is possible to simultaneously display different image information on each of a plurality of selected monitor sets. As the image information supply means, for example, an HD (hard disk) in which image information is stored, an HD driver for reading out the image information, and a digital / analog converter (DAC) for converting a digital signal into an analog signal are used, or a semiconductor memory device. A driver and a DAC for reading the information can be used. Further, as the other image information supplying means, it is possible to use a portable storage medium in which the image information is stored, a driver for reading out the image information stored in the portable storage medium, and a DAC. . As a portable storage medium, for example, a CD (Com
Pact Disc), DVD (Digital Ve)
rsatile Disc), MO (Magnet O)
optical), MD (Mini Disk), memory stick, memory card, ROM card, etc.
Alternatively, the storage capacity is small, but depending on the case, FD (Flopp
y Disc) or the like can also be used. As a driver for reading out image information, for example, a CD player, a DV
There are D players, MO drivers, MD drivers, FD drivers, and drivers for playing memory sticks, memory cards, and ROM cards. By using the portable storage medium and its driver, it becomes easy to replace the contents of the advertisement information regularly and easily without taking the installation place. Further, as the image information supplying means, a video server for supplying the image information and a communication means for transmitting / receiving the image information may be used instead of the portable storage medium. That is, the Internet or a system configuration similar to this may be used. As communication means, telephone line (ADSL, etc.), optical fiber, CATV, digital line (ISDN)
Etc.), satellite communication (BS, CS, etc.), other wireless, etc. can be used. In this case, a network may be constructed by mutually connecting the image information supply means, the plurality of monitor sets, and the image distribution control means. As described above, it is possible to provide a moving object sensing image display system similar to streaming distribution in which a video server is called every time an image display request is made and an image is selectively displayed on a corresponding monitor. Further, it stores the image information transmitted from the video server, for example, a hard disk system, a semiconductor memory system, a writable CD.
A storage means such as a system or a DVD system may be provided. As a result, based on the image information stored in the storage means, a moving object sensing image display system similar to content distribution can be provided, similar to a system using a portable storage medium. In this way, a plurality of moving object sensing image display systems can be connected to one video server via the communication means, and a so-called image information distribution network centered on one video server can be constructed. In this case, one video server can perform unified management. By the way, when displaying advertisements of a plurality of companies or displaying different types of image information, for example, one image information is set for one monitor set. When this moving object detection image display system is installed in, for example, a public toilet or the like, the place to be used is often biased depending on whether the place to use is near or far from the entrance. Therefore, when the image information is fixedly set in each monitor set, in the moving object sensing image display system of the present invention, which targets only individuals near the monitor set, the number of times of displaying all image information may be biased. There is. This makes it unfair to the customer who provides the image information. The image delivery control means of the present invention is a means for measuring the passage of time, or a counter for counting the number of times of delivery of image information, and a constant period based on time information from the means for measuring the passage of time,
Alternatively, there is provided a means for circulating the image information set once for each monitor set among the monitor sets at a constant number of times of distribution based on the distribution number information from the counter. Therefore, even when the number of times of display is biased depending on the installation location of the monitor set, the number of times of display can be averaged for all the image information, so that the unfairness due to the installation location of the monitor set can be eliminated.

When the image information is selectively displayed on the monitor and a detection signal that there is no person near the monitor is output,
The display of image information on the monitor is selectively stopped. As a result, image information can be displayed without waste even when people come and go, only when there are people. Further, it becomes possible to display more effective advertisement information and the like, which is intended only for individuals close to the monitor.
Further, the image information to be displayed is circulated between the respective monitor sets every time a certain period of time elapses or every certain number of times of display. Therefore, even if there is a deviation in the number of times of display depending on the installation location of the monitor set, the number of times of display is averaged for all the image information, so that unfairness due to the installation location of the monitor set can be eliminated. It is also possible to construct a network by connecting a video server that supplies image information, a plurality of monitor sets, and image distribution control means to each other via a communication means that transmits and receives image information. This makes it possible to provide a moving object sensing image display system similar to streaming distribution in which a video server is called for each image display request and images are selectively displayed on a corresponding monitor. Further, by providing the storage means for storing the image information transmitted from the video server, a moving object sensing image display system similar to content distribution can be provided based on the image information stored in the storage means. In this way, an image information distribution network centering on one video server can be constructed, which enables unified management by one video server.
