Description

  The present invention relates to an integrated display system, method, and program, and, for example, a system and method for providing display means on a vehicle body such as a taxi or other vehicles, and displaying contents such as local advertisements on the display means. Can be applied to.

2. Description of the Related Art Conventionally, a vehicle advertisement is displayed while a business vehicle is running, using a telematics technology that applies a communication system applied to an automobile. In general, in such vehicle display systems, large-sized cars such as buses and trucks are advertised with large wrapping advertisements. In addition, advertisements that stand out by the movement of vehicles, and advertisements that are specific to railways are run. It has been broken. Further, there are cases where advertisements in the surrounding area including downtown areas are expected from taxi body advertisements, and various vehicle display systems have been proposed that display local advertisements along the road in a timely manner while a taxi is traveling. (For example, see Patent Documents 1 and 2).
JP 2002-251158 A (paragraph 0040, FIG. 2, etc.) JP 2002-288525 A (paragraph 0019, FIG. 9 etc.)

However, the conventional techniques as described above have the following problems.
(1) Compared with large vehicles, the taxi body cannot be expected to have a wide display surface, so the advertising effect that is more noticeable than large vehicles cannot be expected.
(2) Moreover, it does not reciprocate or circulate around a certain section like a route bus, and it travels comparatively widely various places in many downtowns according to a customer's request. However, when these local advertisements are displayed, their sizes and shapes are different, and it is extremely difficult to switch many of them in a timely manner.
(3) For example, when displaying information on the bar in Shinjuku in Shinjuku and information on the bar in Ikebukuro in Ikebukuro, the emphasis on local advertisements may differ, and there may be differences in appearance. The relatively small display panel could not be shared.
(4) In addition, when a taxi body is provided with a display and a so-called commercial image or video is displayed on this display, it is unusual at first, but it may soon get bored, depending on the idea. Therefore, there is a need for a medium capable of various expressions so that it can be devised so that it can stand out, and the expression method can be changed one after another.
In addition, in taxis, not only showing the advertisement display to the taxi viewer from the street etc., but also by showing the display of other taxis to the passengers who got on the taxi, it is possible to provide services for taxi passengers, There was a request to make taxis attractive and increase the opportunities to take them.

  The present invention has been made in view of the above circumstances, and not only provides various displays on a display surface or the like provided on a vehicle having a limited area, but also allows a vehicle occupant to display other vehicles. An object of the present invention is to provide an integrated display system, method and program that gives an opportunity to see the display provided on the surface.

In order to achieve the above object, according to the first aspect of the present invention, display means provided on each of the outer surfaces of a plurality of vehicles displays content related to the vehicles in proximity when the vehicles are in proximity. An integrated display system,
Content accumulation means for accumulating and storing contents to be displayed on the display means in association with a plurality of preset items,
Proximity detection means for detecting that the vehicles are close to each other;
A selection means provided in the vehicle, for selecting an item from a plurality of preset items;
Operating means for operating the selection by the selecting means;
A content determination unit that searches the content storage unit based on the item selected by the selection unit and extracts content when the proximity detection unit detects that another vehicle has approached;
Content allocating means for displaying the content extracted by the content determining means on the display means of the vehicle,
Content is displayed on the display means of the other vehicle toward the passenger of one of the vehicles in proximity to each other.

In the first aspect of the present invention, the display means is provided in the vehicle, and the content is displayed on the display means. By showing this to a passerby or the like on the road, for example, advertising can be performed. It becomes possible.
Further, in the present invention, when vehicles equipped with display means come close to each other, the content retrieved and extracted based on the preselected items is displayed on the vehicle display means.

In this case, when the vehicles are close to each other, a passenger of one vehicle (for example, a taxi passenger) sees the content displayed on the display means provided on the outer surface of the other vehicle. . In this case, content related to the item selected by the selection means will be displayed. For example, by selecting an item from the region where the vehicle is traveling, the current time zone, etc., it is timely. The content can be displayed and shown to the vehicle occupant.
In addition, by providing an operation means for operating the selection means and allowing the driver or passenger (passenger) to select an item, content related to the passenger can be displayed.

For example, if the vehicle is a taxi, and the passenger is on the taxi, the taxi driver will tell you the gender, approximate age (children, youth, adults, etc.), destination (station, theater, shopping center, food and drink) By inputting a store, a hotel, etc., content corresponding to the gender, age, and destination of the passenger can be displayed on a vehicle equipped with other display means close to the taxi. For example, content related to a new movie can be displayed for passengers heading to a movie theater, and clothing content can be displayed for passengers heading to a department store.
Further, if the vehicle is provided with a passenger operation means that allows the passenger to select an item by operating the selection means, and the passenger (passenger) can select the item by operating the selection means, the passenger The content related to the item desired by the passenger can be displayed on a vehicle in the vicinity of the vehicle on which the passenger rides.

Compare the contents displayed on the display means of the other vehicle to the passenger of one vehicle, especially when vehicles that are close to each other are running side by side or when the vehicles are approaching each other with a red light. It can be shown for a long time. In this case, it is also possible to show not only a still image or text content but also a slide show content composed of a moving image and a plurality of images.
If the selection means is provided with an operation means so that items related to the passenger can be selected, the display related to the passenger is displayed on the display means of the vehicle located in the vicinity of the vehicle on which the rider is riding. By doing so, it is possible to advertise to the passengers and to entertain the passengers while traveling on a taxi or bus.

Here, the vehicle is basically a commercial vehicle on which passengers such as taxis and buses ride, but as a vehicle that displays content on the display means so that it can be seen by passengers of other vehicles, the boarding of taxis, buses, etc. A vehicle other than the vehicle on which the person is placed may be used.
The vehicle is particularly preferably a commercial vehicle using a leased vehicle. If the vehicle is a leased vehicle, the present invention can be integrated with vehicles belonging to a plurality of companies without being limited to the company that uses the vehicle by leasing a vehicle provided with a display means or the like in advance.
Display means include, for example, liquid crystal display (LCD), plasma display panel (PDP) electroluminescence (EL) display, surface conduction electron emitter display (SED), LED display, fluorescent display tube (VFD), electronic paper, etc. Can be used.

The content is data such as text and images (still images and moving images), and is display data including, for example, character images for advertisement. In addition to the display means, the vehicle may be provided with a sound generation device (sound generation circuit, sound reproduction circuit, amplifier, speaker), and the content may include sound data.
For example, the selection means may have a position detection means and a clock function, and may automatically select an item corresponding to the position and time of the vehicle, or may be operated by a driver or a passenger of the vehicle. It is possible to select an item based on the operation of the operating means when the operating means is operated. If the operation means is not operated, an item may be automatically selected based on a region or time, or an item may be selected at random.
As the operation means, for example, a keyboard-like one having a plurality of buttons corresponding to a plurality of items, a touch panel type (tablet type) liquid crystal display, or the like can be used.
The content storage means has a storage device for storing content, and functions as a database that stores the content in a searchable manner.
Further, the content storage means may be provided in each vehicle, or provided in a fixed station, so that the searched content can be output to the vehicle by data communication between the vehicle and the fixed station. Also good.
Further, when the content storage means is in the fixed station, the vehicle needs storage means for temporarily storing the content output from the fixed station.

The proximity detection unit may be a position detection unit that detects an absolute position, such as a GPS device, or a device that relatively measures the positions of vehicles (measures each other's position using electromagnetic waves or the like). A device for measuring the absolute position and a device for measuring the relative position may be used.
Further, the proximity detection means does not necessarily have to be mounted on the vehicle, and includes a device for recognizing the vehicle from structures such as satellites, airships, buildings, etc., thereby measuring the position of the vehicle (remote sensing). May be. In addition, when using GPS as the position detecting means, for example, a method (differential GPS or the like) that improves the measurement system by using an inertial navigation device or the like, or using the GPS device of each vehicle and the GPS of a fixed station, etc. It is necessary to improve the positioning accuracy.

  The content determination means is a computer system provided with a storage device as content storage means, and searches and extracts data in the content storage means. Therefore, the content determination unit is disposed at the same place as the content storage unit.

The content allocating unit stores the content retrieved and extracted by the content determining unit and outputs the content to the display unit. For example, the content allocating unit is mounted on each mobile body. Note that content allocation means may be provided in a fixed station as will be described later instead of a mobile unit to distribute the content, and a device for displaying the distributed content on the display unit may be arranged on the mobile unit side. That is, the content allocating means may be separately arranged on the mobile body side and the fixed station side.
Further, in the integrated display system, a fixed station provided with content storage means is provided, and data communication is performed between the fixed station and each vehicle. For example, which vehicle is based on the position measured by the position measuring means. It is also possible to adopt a configuration in which a fixed station performs processing for determining whether the vehicle is close to the vehicle and searching for content based on the vehicle, and a configuration in which content is distributed to the vehicle by data communication (centralized type). In addition, each vehicle is equipped with content storage means without providing a fixed station, and vehicles adjacent to each other are determined by data communication between the vehicles. Based on this, the content is searched in each vehicle, and the content is displayed in each vehicle. A configuration (distributed type) may be displayed on the means. In this case, the content data is distributed and stored in the storage device (storage means) serving as the content storage means of each vehicle so that the content data is shared among the vehicles in the integrated display system. Depending on the situation, the content may be transmitted and received between the vehicles.
Further, it is preferable that the item selected by the selection means can be transmitted and received by data communication between vehicles close to each other. For example, when an operation means is provided in the selection means, one vehicle on which the passenger rides It is necessary to transmit the item selected in (1) to another vehicle close to the vehicle by data communication. Moreover, when transmitting / receiving the item selected between vehicles, you may make it transmit / receive via a fixed station.

Extract the content to be displayed on the means,
The content allocation unit displays the content extracted by the content determination unit on the fixed display unit.

In the invention described in claim 2, for example, when a vehicle on which a passenger (passenger) rides approaches a fixed structure having a fixed display means, content related to the item selected by the selection means is fixedly displayed. Will be displayed on the means. As a result, the vehicle occupant can see the content related to the item selected by the selection means displayed on the fixed display means.
Therefore, the effect similar to the effect obtained when the passenger sees the content displayed on the display means of another vehicle in claim 1 can be obtained by looking at the display on the fixed display means. In particular, when an item related to the passenger is selected as described above and the content related to the item is displayed, the content is displayed on the fixed display means capable of displaying larger than the vehicle. By doing so, the passenger's interest can be more attracted.

In addition, a passenger who is mounted on a vehicle is attracted by the displayed content because the content related to the same item is displayed on the fixed display means of the fixed structure and the display means of the adjacent vehicle. become. Note that the content related to the same item displayed on the fixed display means and the vehicle display means may be the same (exactly or substantially the same) content, or the content displayed on the fixed display means. A part may be displayed on the display means of the vehicle, or it is content related to one common product or store related to the item, but the display content is different between the fixed display means and the vehicle display means It may be.
The fixed structure is, for example, a building such as a building, and the fixed display means is, for example, a super large display (such as a LED large display) provided on the wall of the building.

In this case, when a vehicle having other display means approaches, the item selected by the selection means is also displayed on the display means of the adjacent vehicle.
Therefore, the content related to the same item can be displayed on the in-vehicle display means and the display means of other nearby vehicles. The passenger who sees this is attracted by the displayed content by displaying the content related to the same item on the display means in the vehicle and the display means on the outer surface of the other vehicle.

  The content related to the same item displayed on the in-vehicle display means and the display means of another vehicle may be the same (exactly or substantially the same) content, or displayed on the in-vehicle display means. A part of the content may be displayed on the vehicle display means, or the content is related to one common product or store related to the item, but the display content is fixed display means and vehicle display means It may be different. In this case, for example, detailed display related to the product or the store may be performed on the in-vehicle display means, and schematic display regarding the product or the store may be performed on the outer surface of another vehicle.

  According to the integrated display system, method and program of the present invention, not only the advertising content can be displayed by the display means mounted on the vehicle, but also the display of other vehicles close to the passenger such as a passenger who has boarded the vehicle. The content displayed on the means can be shown to entertain the passenger.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining a schematic configuration example of a display integration system according to an embodiment of the present invention.
The integrated display system of this example is for displaying contents related to each other as an integrated display means group when display panels Dsp provided as display means provided in a plurality of vehicles are close to each other. However, when the vehicles are close to each other, a passenger who has boarded one of the adjacent vehicles can see the content displayed on the display means of the other vehicle.
That is, the integrated display system is configured to display contents related to each other as an integrated display means group when the display means provided in each of the plurality of vehicles are close to each other. Not only can the content displayed on the display panel Dsp mounted on the vehicle, but also the person who has boarded the vehicle can view the content displayed on the panel Dsp of another vehicle. Yes.

  Here, the present invention provides a display panel Dsp provided on the outer surface side of another vehicle for a passenger who has entered the vehicle, a super large display provided on a wall surface of a building as a fixed structure, or an interior of the vehicle. The purpose of the taxi in this example is to show the content to be displayed on the in-vehicle display to the passenger and to promote the passenger and entertain the passenger. By displaying content on the display panel Dsp provided on the outer surface side, advertisements are also made to passers-by, etc., especially when vehicles are close to each other, The content to be displayed can be displayed.

  Here, before explaining the display of the content to the passenger of the vehicle, a configuration capable of displaying the content in cooperation with a single or a plurality of nearby taxis will be described.

  In this example, when the plurality of taxis (vehicles) Tx1, Tx2,... Connected to the same radio repeater TRx move in a discrete manner and repeatedly stop and start, each display panel Dsp. Are applied to each other to form an integrated display surface to display content such as advertisements. In addition, a content database 1 (content storage means) for advertising content and a narrow-area wireless local area network (wireless LAN: here, a wireless LAN dedicated to taxis is built using the existing wireless repeater TRx. A link analysis server (linkage analysis means) 2 connected to the content database 1 through data communication, and a frame allocation server 3 (content determination means, content allocation means). These database 1 and servers 2 and 3 are mounted on each taxi Tx1, Tx2,. Any taxi Tx1, Tx2,... Can function as a vehicle of this system by communicating with each other through the taxi. For data communication, a mobile phone or PHS communication line, taxi company wireless communication, or the like may be used instead of the wireless LAN. Note that the wireless LAN is connected to, for example, the Internet (INT), but may be connected to an extranet or an intranet operated by a taxi company, an advertising agency described later, or a vehicle leasing company.

Here, the content database 1, the linkage analysis server 2, and the frame allocation server 3 do not have to be separate devices, and may be configured by a single computer system. Text, images (still images, moving images) as content ) And the like (for example, a hard disk or a nonvolatile memory as a storage device) and a computer main body equipped with a CPU or the like. As will be described later, the content database 1, the linkage analysis server 2, and the frame allocation server 3 It is only necessary to be able to execute various programs that function as:
A taxi Tx1, Tx2,... As a vehicle in this example is a wireless communication device that enables data communication such as the content database 1, the linkage analysis server 2, the vehicle-mounted computer system that functions as the frame assignment server 3, and the wireless LAN described above. Is provided. Further, the wireless communication apparatus may have a plurality of directional antennas as described later and function as a relative position measuring unit for specifying a later-described arrangement pattern and relative position in the cooperation analysis server 2. Good.

FIG. 2 is a style diagram for specifically explaining the content database 1 shown in FIG.
The content database 1 shown in FIG. 2 includes image information (layout information) in which advertisement information (display information) groups 10, 10... Filed in association with 12. The description information 11 includes an advertisement ID (Adv0001 in this figure) that is an identification code that allows each advertisement information group 10 to be individually identified, and personal information (name of the billing destination of the advertisement fee) In the figure, it is a table including Name), contact information, etc.), area data indicating the display area (area information), and timer data indicating the display time zone (timer information).

  The image information 12 includes partial image information (Image001, Image002) 13a and 13b relating to each frame of the image information 12, and a position number (1) or (2) relating to the arrangement position of each frame (sub address 01 or 02 in this figure). The number of frames (2 in this figure, the number of mobile objects in the array pattern) and the arrangement (this book) In the figure, it is a table arranged together with data in a way of arrangement indicating that they are arranged in a horizontal row (front and back). In each subsequent process, the total number of frames becomes data for setting the number of taxis that can be displayed in an integrated manner, and the layout of the frames constitutes a cooperative relationship (array pattern) between taxis Tx1, Tx2,. It becomes data, and the pattern code becomes an identification code for specifying the cooperative relationship (array pattern) of the cooperative taxi group. The maximum value to which position numbers (1) and (2) can be added is the maximum number of frames that can be assigned to the advertisement image, and the maximum number (N in this figure) that can maintain the cooperative relationship. Note that either or both of such image information and partial image information may be in a compressed data format, for example, as a pixel value or a vector value.

Here, a frame is an image as a content displayed on each display panel Dsp when, for example, one display panel Dsp is provided in each taxi Tx1, Tx2,. Note that the image need not be a still image, and may be a moving image composed of a series of images.
Further, the number of display panels Dsp provided in the taxis Tx1, Tx2,... Is not limited to one, and may be plural. When there are a plurality of display panels Dsp provided in one taxi Tx1, Tx2,..., The same image may be displayed, or different images may be displayed. When different images are displayed, a plurality of images must be stored in the content database 1 as each frame. In this case, the partial image information described above includes a plurality of images corresponding to a plurality of display panels Dsp provided in one vehicle, and these images are included in one taxi Tx1, Tx2,. .. Stored in a state associated with the panel code corresponding to each display panel Dsp.

The positions of the display panels Dsp provided in the taxis Tx1, Tx2,... Are, for example, side surfaces (doors and front and back thereof) and upper surfaces (upper surfaces such as bonnets, roofs, trunks, etc.) The panel Dsp is formed so that it can be seen by a passerby or a passenger of another automobile, and the display panel Dsp provided on the upper surface is a building or a crosswalk (overpass) overlooking a road or a parking space for waiting for customers. ), Formed so as to be visually recognized from the platform of the station.
In addition, as the display panel Dsp formed on the side surface, for example, it may be formed on a window portion of a door.

Moreover, as a display panel, various flat panel displays, such as LCD, PDP, SED, ELD, VFD, and electronic paper, can be used, for example, As the display panel Dsp formed in a window as mentioned above, it is transparent. It is preferable to use a type LCD or a transflective (semi-transmissive / semi-reflective) LCD to ensure visibility from inside the taxis Tx1, Tx2,.

  Further, the content stored in the content database 1 is basically searched by the above-described pattern code and position number. When there are a plurality of display panels Dsp in one vehicle and each displays different contents, it is necessary to be able to search even with the panel code described above. As the pattern code, a different code is set for each preset arrangement pattern, and the arrangement pattern is determined by specifying the pattern code. In addition, the arrangement pattern includes a pattern in which the vehicle travels, that is, a pattern arranged in one row in the front-rear direction, a pattern arranged in two rows, a pattern arranged in three rows, a pattern arranged diagonally, or orthogonal to the direction of travel. A pattern arranged in the direction to be moved, a pattern arranged in a zigzag, and the like are set, and even in the same one row, two rows, etc., different patterns are set depending on the number of taxis Tx1, Tx2,.

The position number is set for each arrangement pattern. For example, in an arrangement pattern in which three taxis Tx1, Tx2,... Are arranged in a line in the front and rear, position numbers such as 01, 020, 03, etc. in order from the top. Will be assigned. That is, the position number indicates the relative position of each taxi Tx1, Tx2,.
Accordingly, by searching for partial image information by specifying a pattern code and a position number, it is possible to search for contents by specifying an array pattern and a relative position (position) within the array pattern. .

  Note that in the content database 1, at least for each advertisement ID, partial image information is stored for every preset arrangement pattern and for each relative position in each arrangement pattern, and when actually searching for content Requires an advertisement ID in addition to the above-described pattern code and position number. The advertisement ID basically corresponds to the advertiser on a one-to-one basis, but some advertisers may have a plurality of advertisement IDs in order to perform a plurality of different advertisements.

  Here, when the time is specified as the timer data of the description information including the advertisement ID, the advertisement ID is specified by the time by setting so that the time ranges of the timer data do not overlap for each advertisement ID. You may do it. Also, the time ranges indicated by the timer data may not overlap in each area data, and the advertisement ID may not overlap from the area data and the timer data. For example, even if two or more advertisement IDs are defined (Adv001, Adv002) for a time range (timer data) from 3:00 to 3:30, these advertisement IDs It is only necessary that the corresponding area codes are different. Thus, the advertisement ID can be specified from the area data and the timer data, and the partial image information can be searched from the pattern code and the position number.

In addition, when the timer data and the area data are specified, when a plurality of advertisement IDs are applicable, for example, a priority order and a time limit for each advertisement ID are provided, and an advertisement with a high priority order is provided. The ID is selected. In addition, when the content belonging to the selected advertisement ID is displayed, the display time is measured, and when the display time becomes the time limit, the advertisement ID having the next highest priority is selected. Also good.
Further, when searching the content database 1, all of the timer data, area data, advertisement ID, pattern code, and position number may be designated and searched.
In order to search the content database 1 by designating timer data and area data, a clock for designating time and a position measuring means for designating the absolute position of the vehicle as area data are mounted on the vehicle. Need to be. The watch function is mounted on the in-vehicle computer system, and the position measuring means is mounted with a GPS device used for specifying the array pattern and the relative position within the array pattern. If the GPS device is not mounted by using the relative position measuring means as will be described later in order to obtain the array pattern and the relative position in the array pattern, the area as the absolute position by the radio repeater TRx with which the vehicle communicates (Area) may be specified.
That is, at least one radio repeater TRx is provided for each area indicated by each area data, and when the vehicle moves from one area to another area, the radio repeater TRx to be communicated is switched. Thus, the area may be specified depending on which radio repeater TRx is communicating with.
From the above, the content database 1 displays the content to be displayed on the display means as an array pattern indicating the number of the groups of vehicles adjacent to each other and the arrangement of the groups of vehicles, and the relative positions of the vehicles in the array pattern. It functions as content storage means for storing and storing in association with.

  In addition, the above-mentioned arrangement pattern includes an arrangement pattern of a single vehicle in which no other vehicle exists in the vicinity of the vehicle, and content is stored in the content database 1 corresponding to the single arrangement pattern. Yes. Since there is only one taxi Tx1, Tx2,... In a single arrangement pattern, only one position number indicating a relative position is set independently. That is, a single position number is assigned to a single arrangement pattern corresponding to a single vehicle.

FIG. 3 is a schematic diagram for explaining a visual example of image information.
The image information 12 shown in FIG. 3 constitutes one advertisement image (in this figure (not shown for public order and morals violation)) by arranging the frames of the two partial image information 13a and 13b in a line in the front and rear direction. is doing. Accordingly, for these two frames, if the partial image information 13a, 13b is distributed to each display panel Dsp provided on the roof (roof) of the head taxi Tx1 and the subsequent taxi Tx2 that are linked to each other. , The advertisement image can be displayed in an integrated manner. Such image information is configured to have different sets of timer data for each set by setting a plurality of sets by changing the number of frames, shape and size of the same advertisement information, or by arranging a plurality of frames. Good. As a result, it is possible to change the way the image information is displayed and to improve the advertising effect.

In addition, the partial image information does not actually need to indicate a part of one image. However, for example, when the partial image information is arranged in the front-rear direction with respect to the traveling direction, the partial image information has a relationship corresponding to the front-rear relationship. It is preferable. Depending on the case, the same image data (characters may be images) may be assigned as each piece of partial image information, or image data having no positional relationship may be assigned as partial image information within the same arrangement pattern. It may be taken.
Further, the partial image information may be a moving image as described above, or may be composed of a plurality of series of image data whose order is designated in advance. For example, the partial image information is sequentially switched every 10 seconds or the like. It may be image data that is displayed. In the sequentially switched images, the order of the images may be meaningful (story-like) or random.

FIG. 4 is a style diagram for explaining a specific example of the cooperation analysis server shown in FIG.
As shown in FIG. 4, the data calculated and stored by the cooperative analysis server 2 collects coordinate information 21 regarding the current position of each taxi by communicating with a plurality of taxis through a narrow area wireless LAN. Based on the coordinate information 21, at least one linked taxi group Tx1, Tx2,... With which each taxi cooperates is extracted, and in this linked taxi group Tx1, Tx2,. It is obtained by organizing pattern information 22 related to the cooperative relationship and specifying each taxi Tx1, Tx2,... Of the cooperative taxi group Tx1, Tx2,.

The coordinate information 21 shown in FIG. 4 is measured and collected by the GPS for each taxi Tx1, Tx2, and the vehicle ID (distribution address 01 in this figure), the date and time of positioning, and the hour, minute, second are used as the current time. Time (Ymmdd-hhmmss in this figure), latitude (N350000 in this figure), longitude (E1350000 in this figure), traveling direction (E in this figure), speed (book) In the figure, it is 00 (parking).
The pattern information 22 is linked to the pattern code of the identification code (01 in this figure), the number of taxis Tx1 and Tx2 that are linked (two in this figure), and the linkage relationship (in this figure, one horizontal line (one line before and after)). Data of contents indicating to be performed) and position numbers (1) and (2) (vehicle ID 01 or 02 in this figure). The maximum value to which position numbers (1) and (2) can be added is the maximum number (N in this figure), which is the maximum number of frames. That is, among the most frequent position numbers (1) to N, only the first two units are used in this example. Such pattern information may be a pixel value, a vector value, a compressed data format, or the like. As for the time lag from the positioning process to the display process, the image information can be corrected, interpolated, deformed, etc., based on the data of the speed and the traveling direction. Ad can be displayed in an integrated manner. Speed data is obtained from taxi speedometers. Further, the traveling direction is measured by an azimuth meter (for example, a magnetic sensor or a gyro sensor).

FIG. 5 is a diagram for explaining the position numbers of the linked taxi group shown in FIG.
In FIG. 5, in the pattern code 22a, the position number (1) indicates the head taxi Tx1 in the traveling direction in the group of linked taxis, and the position number (2) indicates the following taxi Tx2. The array pattern indicated by 22a is a series of two units in the front and rear. In the pattern code 22b of the array pattern in which the three cars are arranged in a horizontal row (front and back), the follow-up taxi Tx3 at position (3) is increased rearward with respect to the array pattern indicated by the pattern code 22a. Further, in the pattern code 22c of the array pattern in which six cars are arranged vertically and horizontally, the following taxi Tx4, Tx5, Tx6 (position numbers (4) to (6)) following the position number (3) with respect to the pattern code 22b. This indicates that the row is arranged on the left side in the traveling direction of the vehicle row indicated by the position numbers (1) to (3).

In the above example, the arrangement pattern is set using the latitude and longitude obtained by the GPS device. In this case, if there is a certain distance between vehicles due to a measurement error expected from the GPS device, the difference in position between each taxi Tx1, Tx2,. When Tx2 ... are parked and parked side by side, or when traveling at low speed, the distance between each vehicle is within the GPS error range, making it difficult to accurately determine the array pattern Become.
Therefore, for example, by using a known positioning accuracy improving method such as differential GPS, it is possible to confirm an accurate arrangement pattern even with GPS.

Here, the function as the cooperative analysis server 2 in the in-vehicle computer system mounted in the taxis Tx1, Tx2,... Uses, for example, a wireless communication device with other taxis Tx1, Tx2,. The identification information (vehicle ID) that can identify the taxi Tx1, Tx2,... And the latitude / longitude measured by the current GPS of the other taxi Tx1, Tx2,. And memorized.
Then, the in-vehicle computer system has a taxi Tx1, Tx2,..., Its own latitude / longitude on which the vehicle-mounted computer system is mounted, for example, within a predetermined distance (for example, 5 m) from the latitude / longitude received and stored. Search for vehicles with latitude and longitude. Then, when there is a latitude / longitude within the searched predetermined distance, the identification information (vehicle ID) and the direction with respect to its own latitude / longitude are determined based on its traveling direction.

  As shown in FIG. 6, in the taxi-mounted computer system shown as (1), for example, one taxi shown as (2) is searched behind in a predetermined distance. On the other hand, in the taxi-mounted computer system indicated by (2) close to the rear of the taxi indicated by (1), one taxi indicated by (1) is searched forward.

In the in-vehicle computer system, an array pattern arranged in front and rear is searched from the array patterns that are set and stored in advance, and the pattern code is acquired.
Further, in the array pattern in which the two front and rear are arranged, the position number of the front taxi Tx1 is 1, and the position number of the rear taxi Tx2 is 2. That is, the relative position of each taxi Tx1, Tx2,... Within a predetermined distance is determined.

  In the above processing, after identifying taxis Tx1, Tx2,... Within a predetermined distance range for each adjacent taxi Tx1, Tx2,..., Data for each taxi Tx1, Tx2,. By sharing, even when taxis Tx1, Tx2,... Are lined up in a long line of a predetermined distance or more (even if they are separated by a predetermined distance or more at the head and tail), a group of taxis Tx1, It is recognized as Tx2. That is, when the arrangement of other taxis Tx1, Tx2,... Around the taxis Tx1, Tx2,... Is specified, there are other taxis Tx1, Tx2,. Each taxi Tx1, Tx2,... Is recognized as a group of taxis Tx1, Tx2,... Together with other taxis Tx1, Tx2,. A group consisting of a plurality of taxis Tx1, Tx2,. Here, two or more groups including the same vehicle ID are combined into one group, and the group further combined is compared with other groups (including groups already combined). When the same vehicle ID is included in each of these groups, the groups are again combined into one group, so that the distance between at least the nearest taxis Tx1, Tx2,. The plurality of taxis Tx1, Tx2,... That are close to each other are regarded as a group of vehicles.

Moreover, when combining a plurality of groups into one, the relative positions of the respective taxis Tx1, Tx2,... In the respective groups before being combined are set as taxis Tx1, Tx2,. The relative positions of the respective taxis Tx1, Tx2,... Within the grouped group, that is, the determined arrangement pattern are determined by combining them so as to overlap each other.
For each taxi Tx1, Tx2,..., The arrangement pattern and the relative position within the arrangement pattern are obtained. Here, as described above, when there is no other taxi Tx1, Tx2,... Close to the periphery (within a predetermined distance), it is determined as a single arrangement pattern.

The in-vehicle computer system functioning as the linkage analysis server 2 includes an array pattern data table in which a preset array pattern and a pattern code are associated with each other, and a relative position (for example, a traveling direction) in each array pattern for each array pattern And a relative position data table in which the position number and the position specified as the number from the front and the position from the right are associated with each other.
A pattern code and a position number for searching the content database 1 are obtained by referring to the arrangement pattern data table and the relative position data table based on the arrangement pattern obtained as described above and the relative position in the arrangement pattern. be able to.

On the other hand, the method for determining the arrangement pattern is not limited to the method using the GPS described above, and for example, the following method can be used.
As shown in FIG. 7, each taxi Tx1, Tx2,... Has a plurality (for example, eight) of directional antennas 31, a wireless communication device 32 connected to the directional antennas 31, and the wireless communication device. And an in-vehicle computer system 33 that functions as the cooperative analysis server 2 connected to the computer.

The directional antennas 31 are respectively arranged radially with the direction of directivity facing outward, and are arranged at an angle (interval) that is an equal angle (for example, 45 degrees).
The wireless communication device 32 is connected to the directional antenna 31 so as to be capable of scanning in order. For example, the directional antenna 31 is sequentially switched and connected to the receiving unit of the wireless communication device 32 every very short time.
Thereby, the radio wave intensity can be measured for each directional antenna 31 and can be compared.

In the wireless communication device 32, radio waves in a predetermined frequency band (hereinafter referred to as measurement radio waves) including identification information (vehicle ID) that can identify itself (each taxi Tx1, Tx2,...) As a digital signal or an analog signal. Is transmitted at a weak predetermined strength.
Therefore, taxis Tx1, Tx2,... Are in a state of transmitting measurement radio waves that can identify themselves and receiving measurement radio waves of other taxis Tx1, Tx2,.

The in-vehicle computer system 33 connected to the wireless communication device 32 receives the radio wave intensity received by the wireless communication device 32 for each directional antenna 31 and the vehicle ID.
In the in-vehicle computer system 33, when the received radio wave intensity (the highest radio wave intensity received by each directional antenna 31) is equal to or higher than a predetermined intensity, another taxi Tx1 , Tx2... Are determined to exist within a predetermined distance. In this case, based on which directional antenna 31 has the strongest radio field intensity, the direction in which the directional antenna 31 has the strongest received radio field intensity is based on the vehicle ID indicated in the measurement radio wave. The directions are specified taxis Tx1, Tx2,. Note that the direction of the directional antenna 31 is the traveling direction of the taxis Tx1, Tx2,. That is, the directional antenna 31 that faces the traveling direction serving as the reference direction is the front, and the directional antennas 31 are the right diagonally forward, right, diagonally backward, back, diagonally backward, left, diagonally forward left, respectively. Is arranged. Further, the direction of the directional antenna 31 having the highest reception strength is not set to the directions of the adjacent taxis Tx1, Tx2,..., But more accurately using the reception strengths of the plurality of directional antennas 31. The direction may be calculated.

Basically, in each taxi Tx1, Tx2,..., There are other taxis Tx1, Tx2,... That are within a predetermined distance range (for example, a radius of 5 m) where the received measurement radio waves have a predetermined intensity. When recognized, the other taxis Tx1, Tx2,... Recognized by the other recognized taxis Tx1, Tx2,... By wireless data communication (for example, using a frequency band different from the measurement radio wave). Share the information of ... Note that the predetermined strength is experimentally determined by, for example, the reception strength when a weak radio wave having a predetermined strength is transmitted at a predetermined distance.
For example, as shown in FIG. 8, the vehicle A as taxis Tx1, Tx2,... Recognizes the vehicle B behind, recognizes the vehicle C on the left side in the traveling direction, and recognizes the vehicle D diagonally left rear. .

Further, the vehicle B as the taxis Tx1, Tx2,... Recognizes the vehicle A forward, recognizes the vehicle D on the left side in the traveling direction, and recognizes the vehicle C diagonally left forward. In addition, the other three vehicles are recognized in the vehicles C and D as the taxis Tx1, Tx2,. By sharing these, it is possible to grasp the arrangement of the four vehicles A, B, C, D (for example, 2 × 2 state vertically and horizontally). As a result, the pattern code indicating the arrangement pattern and the position number indicating the relative position in the arrangement pattern can be specified.
When all the adjacent vehicles A, B, C, and D are recognized as described above, the relative positions of the vehicles in the arrangement pattern and the arrangement pattern in each of the vehicles A, B, C, and D. Can be recognized, and it is not always necessary to share the arrangement pattern by data communication. Further, even when three or more vehicles are arranged in the same direction, it is possible to determine the distance based on the strength of the reception level of the measurement electric field from the same direction and recognize the arrangement order of the vehicles.

However, when multiple taxis are lined up for a long time, the reception level of the measurement radio wave from the last vehicle may not exceed the predetermined intensity in the first vehicle, and one vehicle is close to each other. When all the vehicles in a group cannot be recognized, it is possible to reliably determine the arrangement pattern by sharing the vehicle ID and the arrangement pattern of the vehicles recognized by a plurality of vehicles. That is, as in the case of using the GPS described above, the target vehicles share data, so that the entire vehicle can be specified as a group of vehicles even in a plurality of vehicles in a long row.
A vehicle in which the reception level of the measurement radio wave does not exceed a predetermined intensity is determined as a vehicle having a single arrangement pattern.
As described above, the cooperation analysis server 2 as the cooperation analysis unit specifies the array pattern to which each vehicle belongs, and specifies the relative position of the vehicle in the specified array pattern.

  In addition, from the above, the cooperation analysis server 2 as the cooperation analysis means is provided for each vehicle and is transmitted from each vehicle and the wireless communication device 32 having a plurality of directional antennas 31 directed in different directions. And an in-vehicle computer system 33 as a relative position calculation means for calculating the distance and direction of the vehicles that are close to each other based on the radio intensity of the radio wave received by each directional antenna of each vehicle, and the vehicles that are close to each other And providing an in-vehicle computer system 33 as an array pattern calculating means for obtaining the array pattern and the relative position in the array pattern by sharing data on the direction and distance of the vehicles existing around each vehicle. Become. Note that a radio communication device 32 having a directional antenna 31 and a GPS device are used in combination, and the absolute position is measured by a GPS device that is not particularly highly accurate to identify vehicles that are close to each other, and the relative position is determined by directivity. It is good also as what determines with the radio | wireless communication apparatus 32 provided with the antenna 31. FIG.

  As will be described later, when the linkage analysis server 7 is arranged in a fixed station, the position information by GPS from each taxi Tx1, Tx2,..., The wireless communication device 32 having the directional antenna 31 and the in-vehicle computer. By outputting an array pattern or the like centered on itself determined by the system 33 from the vehicle side to the fixed station side, each vehicle in a state where the data is shared as described above by the cooperation analysis server 7 provided in the fixed station. And the relative position within the array pattern can be obtained.

The frame allocation server 3 searches the content database 1 for the image information 12 corresponding to the pattern information 22 from the advertisement information candidate group, thereby acquiring the corresponding advertisement information 11, as well as the partial image related to each frame. Information 13a, 13b is allocated to each taxi Tx1, Tx2,. As will be described later, when the content database 6, the linkage analysis server 7, and the frame allocation server 8 are arranged in the fixed station, the partial image information 13a, 13b group is transferred to each taxi Tx1, Tx2,.・ It will be delivered to.
And these partial image information 13a, 13b group is displayed as a vehicle body advertisement by each display panel Dsp of taxi Tx1, Tx2, .... Such display panels Dsp are provided on the front, rear, left and right and upper and lower surfaces of the vehicle body such as the roof, bonnet, door, and trunk lid as described above. In addition, the connection to the narrow-area wireless network LAN can be performed through a vehicle-mounted antenna for vehicle-mounted radio.

Here, the in-vehicle computer system 33 as the frame assignment server 3 is based on the vehicle arrangement pattern (pattern code) and the relative position (position number) of the vehicle obtained by the function as the cooperation analysis server 2 as described above. The database constructed in the storage device is searched as the content database 1, the content data corresponding to the pattern code and the position number is read out, stored in the memory for the display panel Dsp, and output to the display panel Dsp for display. It is displayed on the panel Dsp.
That is, the frame allocation server 3 as the content determination unit searches the content storage unit based on the array pattern to which the vehicle specified by the link analysis unit belongs and the relative position in the array pattern, and extracts the content. The frame allocating server 3 as the content allocating unit determines the content retrieved by the content deciding unit based on the arrangement pattern specified by the cooperation analysis unit of the vehicle and the relative position in the arrangement pattern. It is displayed on the display means.

  The above-described processing by the in-vehicle computer system 33 is repeatedly performed every short time, and the content database 1 every time the arrangement pattern to which each vehicle belongs, the relative position, etc. change with the passage of time. A new content is read out from and displayed on the display panel Dsp. As a result, the taxi Tx1, Tx2,... As each vehicle moves, and when the arrangement pattern to which the taxis Tx1, Tx2,. It is displayed on Dsp.

That is, the cooperation analysis server 2 as the cooperation analysis means performs a change in the arrangement pattern to which the vehicle belongs and a change in the relative position in the arrangement pattern based on the change in the position of the taxis Tx1, Tx2,. Monitoring is always performed, and the array pattern and the relative position after the change of each vehicle are output in response to the change of the array pattern and the change of the relative position.
Further, the frame allocation server 3 as the content determination unit searches for and outputs the content from the content storage unit corresponding to the change of the arrangement pattern to which the vehicle belongs and the relative position output from the cooperation analysis unit. become.
Further, the frame allocation server 3 as the content allocation unit replaces the content in accordance with the change in the arrangement pattern to which each vehicle belongs and the relative position in the arrangement pattern based on the content output from the content determination unit. Thus, it is displayed on the display panel Dsp as a display means.

  In addition, a plurality of still data and moving image data are included in one content, and it is possible to switch and display on the display panel Dsp every unit time, and a plurality of taxis Tx1, Tx2,. Can be synchronized between. That is, the frame allocation server 3 as the content allocation unit is configured to be able to display a plurality of contents on the display panel Dsp as the display unit by switching over time, and is synchronized with the display units of other nearby vehicles. The content is switched and displayed.

  Therefore, for example, a taxi Tx1, Tx2,... That is traveling in a state where the relative position is also independent by becoming a single arrangement pattern is another taxi Tx1, Tx2,.・ If the vehicle is close to the vehicle, or if multiple vehicles are parked close to each other at the taxi stand, the content for single travel is used for an array pattern composed of multiple taxis Tx1, Tx2,. Will change to the content. In this case, for example, one image data for a single arrangement pattern changes to a state where it is enlarged and divided into a plurality of units, or when there are only two display items in the case of a single unit, for example. When the number of taxis Tx1, Tx2,... That stop nearby is increased, content having new items can be displayed. For example, when the array pattern is single, the product name and one product image are displayed on the display panel Dsp of one taxi Tx1, Tx2,..., And the array pattern becomes two array patterns. Displays the other two product images on the display panel Dsp of the second taxi Tx1, Tx2,..., And then displays the product specifications on the third unit whenever the number of array patterns increases. It is possible to display the product variation on the fourth unit and the desired retail price on the fifth unit.

  These displays are displayed according to the contents produced in advance by searching the contents stored in the contents database 1 in advance with the arrangement pattern and relative position. That is, it is necessary to produce in advance a content whose display changes as described above and store it in the content database 1 based on the arrangement pattern and the relative position.

In addition, in each of the plurality of taxis Tx1, Tx2,..., The displayed contents may not be seen as one content by combining them, and each is the same content. Also good.
In this case, in the single arrangement pattern, when the taxis Tx1, Tx2,... Displaying different contents are close to each other, it is possible to perform an effect such that the same contents are displayed.

  Further, when a plurality of contents are switched and displayed in a short time, if the taxis Tx1, Tx2,. Although the display order of the contents is different, the taxi Tx1, Tx2,... May be controlled so that the switching timing and the content switching order become the same when they are close to each other.

  In this case, for example, a switching timing synchronization signal is output from one specific taxi Tx1, Tx2... (For example, taxi Tx1, Tx2. In addition to matching the synchronization timing, when the switching order is also input, the control may be performed so that the switching order is set in advance.

In addition, the content is not switched at the same time, but the content is switched in a wave shape by shifting the timing slightly from the head of the taxis Tx1, Tx2,. Etc. In this case, for example, after the synchronization signal from the vehicle having the position number (1) is turned ON, the other vehicles may sequentially switch the contents by shifting the time based on the relative position.
In this example, when taxis Tx1, Tx2,... Are traveling independently, content for a single arrangement pattern is displayed on each display panel Dsp, and taxis Tx1, Tx2,. Then, the display which cooperates mutually is performed on the display panel Dsp of taxi Tx1, Tx2 ... which adjoined. Here, the term “cooperation” refers to a case where the display contents are related to each other. For example, the display may be different displays for the same product, or each divided portion when one display is divided into a plurality of pieces. Alternatively, it includes a display that can be switched at the timing when the same content is linked (same timing, timing shifted every predetermined time, etc.).

By doing in this way, when a plurality of taxis Tx1, Tx2,... Are close to each other, it is possible to perform display with a high effect using each display panel Dsp.
The taxis Tx1, Tx2,... Used here may be, for example, taxis Tx1, Tx2,... Of the same taxi company. For example, a vehicle leasing company that delivers vehicles to each taxi company The equipment necessary for the integrated display system of the present invention is attached to the vehicle in advance and leased to the taxi company, and the vehicle leasing company and the advertising agency contracted with the taxi company contracted with the advertiser, and stored in the content database 1. The content may be stored and stored. Alternatively, an advertising agency may contract with a plurality of vehicle leasing companies, so that even vehicles of different vehicle leasing companies may be vehicles belonging to one integrated display system. In these cases, taxi companies can obtain advertising revenues from advertising agencies, and vehicle leasing companies also receive advertising revenues from advertising agencies, including advertising costs and equipment costs for in-vehicle devices installed in vehicles. Even if a vehicle leasing company does not earn advertising revenue, renting a vehicle from the vehicle leasing company may benefit from the possibility of obtaining many contracts from a taxi company that can obtain advertising revenue. can get.

In the above description, the in-vehicle computer system (including the database storage device) of each vehicle (taxi Tx1, Tx2,...) Has the functions of the content data server 1, the linkage analysis server 2, and the frame allocation server 3. However, as shown in FIG. 9, a content database 6, a linkage analysis server 7, and a frame allocation server 3 as a computer system may be provided on the fixed station side. Reference numeral 6 a is a terminal device for data input to the content database 6, the linkage analysis server 7, and the frame assignment server 3.
Each taxi Tx1, Tx2,... Controls the display panel Dsp, and receives and stores the content determined by the frame allocation server 3 through data communication and displays it on the display panel Dsp. An in-vehicle computer system is required.

  And multiple taxis Tx1, Tx2, etc. belonging to one business unit or a cooperative organization consisting of a plurality of business units or contracted with one vehicle leasing company or advertising agency repeatedly park and pick up On the other hand, it is applied to display contents such as advertisements by linking the display panels Dsp to each other to form an integrated display surface, and the computer center of the relevant business entity (or vehicle sheathed vehicle, advertising agency) Etc. are provided with the above-mentioned fixed stations. In addition, the content database 6 for advertisement, the linkage analysis server 7 connected to the content database 6 through the Internet INT, and the frame allocation server 8 are also included. You may make it the structure which distributes these content databases 6, the cooperation analysis server 7, or the frame allocation server 8 for every business entity, business place, or building. That is, you may provide the content database 6, the cooperation analysis server 7, or the frame allocation server 8 for every area of the above-mentioned area data. Instead of the Internet INT, for example, an extranet such as the business entity, an intranet, or other telecommunication lines may be used. Moreover, it may replace with a taxi and may comprise another structure with the other various registered vehicles.

The content database 6 is responsible for the function corresponding to the content database 1 in this system, and the linkage analysis server 7 and the frame allocation server 8 are provided for each taxi Tx1, Tx2,. By communicating with the vehicle terminal, it is possible to perform functions corresponding to the functions corresponding to the cooperation analysis server 2 or the frame allocation server 3.
In addition, the location information of each taxi is monitored, and image information can be forcibly transmitted from each server, and advertisement information with regularity is sequentially applied to taxis that pass through a certain point. It can also be sent and displayed to make it stand out as advertising information. Furthermore, by instructing a selected taxi or the like to collect, a plurality of vehicles can be linked to display advertisement information. In the display panel Dsp group, a panel that cannot be seen by passengers, passersby, or the like (for example, on the side opposite to the sidewalk) may be added with a function of blocking its display processing to improve efficiency. Furthermore, instead of a taxi, for example, a bus, a garbage truck, a freight car, a train, or other vehicles that operate on a route may be used.

Next, an example of the integrated display method according to the embodiment of the present invention will be described. That is, a software process example will be described with reference to an example of a flowchart shown in FIG. 10 and each of the drawings shown in FIGS.
As a preparatory preparation, the content databases 1 and 6, the linkage analysis servers 2 and 7, and the frame allocation servers 3 and 8 are activated and initialized by a vehicle terminal mounted in a taxi and a management terminal of a computer center. The wireless repeater TRx or the Internet is connected. In addition, advertisement information regarding advertisements in various taxi business areas is registered in advance in the content databases 1 and 6 through the Internet or the like by registration terminals (registration means) such as advertising companies and advertisers. Such software and content may be downloaded through the Internet or distributed on a CD (Compact Disc) ROM or the like for client computers such as vehicle terminals and registration terminals. That is, the contents databases 1 and 6 store and store the contents in advance in association with each item as described above.

  Hereinafter, a case where the content database 1, the linkage analysis server 2, and the frame allocation server 3 installed in each taxi are used (in the case illustrated in FIG. 1) will be described as an example. First, when each coordinate information 11 is collected from all taxis by the collaboration analysis server 2 (step ST2), a group of coordinated taxis is extracted from the current position of these coordinate information 11 (step ST2), and the content database 1 Is selected to select a candidate group of advertisement information (step ST3). Even if the current position of the taxi is determined by positioning with GPS (Global Positioning System), it can be easily determined as the jurisdiction of the wireless network LAN by connecting to the narrow-area wireless network LAN. Also good. As for the cooperative relationship in the cooperative taxi group, it is assumed that a nearby radio wave with a predetermined intensity or more from another taxi is detected by a directional antenna and is within a predetermined distance. It is relatively discriminated that they are adjacent to each other (parallel running, temporary stop, parking, etc.). By exchanging information between these taxis, the taxi that has detected that the head taxi Tx1 discriminates the following taxi Tx2 and does not adjoin the other direction (for example, the traveling direction). An algorithm that functions as a head taxi Tx1 candidate, identifies the vehicle ID, position number, number of linkages, etc. of the adjacent taxi Tx2 groups in order, and analyzes the current position identification, display start, and display end processing in synchronization. May be configured.

  Next, by specifying the pattern information 22 indicating the arrangement of each taxi in the linked taxi group (step ST4), image information is acquired from the advertisement information candidate group (step ST5), and the position position of the position number is obtained. The partial image information is assigned to each vehicle ID (step ST6), and the partial image information is distributed to the distribution address of each vehicle ID (step ST7). Therefore, when such a taxi, instead of taxis, configures a wireless communication network with, for example, an outdoor multi-vision provided on the wall surface of a building, the taxi passes in front of the multi-vision, parks, stops temporarily, etc. Alternatively, the display screens may be integrated by participating in the network of the present system.

FIG. 11 is a flowchart for explaining a specific example of the start and end processes shown in FIG.
In the start process (step ST1), first, each taxi TX1, TX2 performs predetermined initial settings by detecting the approach of another taxi (step ST11). Next, communication with the other taxi is performed to cause the taxi to perform initial setting (step ST12), and then synchronization processing is performed by sharing information between both taxis including the system timer (step ST13). . In the end process (step ST9), first, for example, a set time is displayed on the distributed partial image information on the display panel (step ST91), and then the display is normally ended or the set time is set. Even if the taxi is within the range of the set distance, it is detected that the taxis are distant and distant from each other, and the display is interrupted, and the process ends normally together with a predetermined process for canceling the cooperation (step ST92).

  The above-described integrated display method is an example, and in the integrated display method, a plurality of contents are accumulated and stored in advance in the content database 1 in association with the arrangement pattern and the relative position in the arrangement pattern, as described above. For each vehicle, the arrangement pattern and the relative position within the arrangement pattern are obtained, and the content database 1 is searched based on these to obtain the content. It only needs to be able to display. Further, when the vehicles are separated from each other by a predetermined distance or more, the content searched for based on the single arrangement pattern as described above may be displayed instead of ending the display.

Also, as described above, when searching for content from the content database, in addition to the pattern code and position number, the time obtained by the clock set in the in-vehicle computer, the area obtained by the above-described position measuring means, etc. Are input to the above-described content database 1 area data (latitude / longitude data to be an area range) and timer data (each time zone when a day is divided into a plurality of time zones). Content may be selected, so that, for example, in areas such as Shinjuku, Shibuya, Ginza, etc., it is possible to display content that is advertisements for stores in that area, and for example, corresponding to store opening hours You can display content that will serve as store advertisements.
That is, the taxi Tx1, Tx2,... Has a GPS or the like as a position measuring means for measuring the absolute position, and a function as a time measuring means for measuring the current time in the in-vehicle computer system. As described above, the contents are classified and stored for each arrangement pattern and relative position, and are classified and stored for each region (area) and time range (timer data). , Based on the relative position, the area (area data) to which the vehicle position measured by the position measuring means belongs, and the current time (time within the time range set in the timer data) measured by the time measuring means. The contents database 1 is searched to extract contents.
The timer data is set, for example, as 0 to 5 o'clock, 6 to 10 o'clock, 10 to 15 o'clock, 15 to 19 o'clock, 20 to 24 o'clock, etc. , The data set at 15:00 to 15:00 is retrieved. The area data may be set as latitudes ab and longitudes cd, for example, or the latitude and longitude may be registered as an area range such as a municipality or a ward on the map data. Good.

Next, with reference to FIG. 12, when taxis Tx1, Tx2,... Having other display panels dsp approach each other, another taxi Tx1 is directed toward passengers as passengers of taxis Tx1, Tx2,. A method of displaying contents on the display panel Dsp of Tx2. That is, a description will be given of an integrated display system in which display means provided on each of the outer surfaces of a plurality of vehicles display content related to vehicles in proximity when the vehicles are close to each other.
In the taxis Tx1, Tx2,..., In addition to the configuration described in the above example, a touch panel type liquid crystal display 35 (hereinafter referred to as an in-vehicle display means and an operation means for the selection means) is provided on the back of the front seat which is the front side of the rear seat. (Abbreviated as TPLCD 35).
The TPLCD 35 is connected to the in-vehicle computer system 33 so that a plurality of items can be selected hierarchically.

For example, buttons for items such as shopping, eating and drinking, movies, etc. are displayed on the first level screen displayed on the TPLCD 35, and touching the shopping button will display clothing, furniture, and appliances as one screen on the second level. When a button such as a grocery item is displayed and further a button for clothing is touched, a button for each of a plurality of clothing stores is displayed as one screen of the third hierarchy. Then, when the button of the third hierarchy is displayed, the content stored for each clothing store stored and stored in the content database 1 as described later (for example, content introducing a store or a product in the store) is selected. It is extracted and displayed based on the selected item.
In other words, the TPLCD 35 is an operation unit that is provided in the vehicle and operates selection by a selection unit that selects an item from a plurality of preset items.
