The present invention relates to a side device, an image information download system, and an image information download method.

 蓄積されたカメラの画像情報を無線通信にてダウンロードするには、安定して通信を行える環境が要求される。このような環境を実現する一例として、カメラを用いた光学的な手段で通信相手を発見し、当該通信相手と通信を行うことが考えられる。 In order to download stored camera image information by wireless communication, an environment in which stable communication can be performed is required. As an example for realizing such an environment, it is conceivable to discover a communicating party by an optical means using a camera and communicate with the communicating party.

 監視カメラは長期間の監視を行うため、カメラに蓄積される画像情報の容量は膨大なものとなる。そのため、この画像情報を端末側装置にダウンロードさせるためには、高速通信を行うことのできる無線通信方式を使用することが好適である。このような無線通信方式の一例として、ミリ波帯を用いる無線通信(例えば、WiGig(登録商標・IEEE802.11ad))が考えられる。 Since the surveillance camera monitors for a long time, the volume of image information stored in the camera is enormous. Therefore, in order to cause the terminal device to download the image information, it is preferable to use a wireless communication method capable of high-speed communication. As an example of such a wireless communication method, wireless communication using a millimeter wave band (for example, WiGig (registered trademark · IEEE 802.11ad)) can be considered.

 しかしながら、ミリ波は直進性が高く、減衰しやすい性質を持つため、安定した通信を行うためには端末側装置の位置及びアンテナの角度を精密に調整することが求められる。すなわち、ミリ波帯を用いた無線通信を使用して画像情報を端末側装置でダウンロードする場合、カメラ側装置と端末側装置との間の伝搬損失を抑制するため、端末側装置の位置やアンテナの角度を、ミリ波の減衰の少ない位置やカメラ側装置に設置された無線装置のアンテナの向き及び偏波面に合わせることが求められる。しかしながら、ミリ波帯による通信技術を熟知していないユーザが、これらの位置及び角度を好適なものに調整することは難しいという課題がある。 However, the millimeter wave has a high rectilinearity and easily attenuates. Therefore, in order to perform stable communication, it is required to precisely adjust the position of the terminal device and the angle of the antenna. That is, when image information is downloaded by the terminal device using wireless communication using the millimeter wave band, the position and antenna of the terminal device can be reduced in order to suppress the propagation loss between the camera device and the terminal device. It is required to adjust the angle of (1) to the position where the attenuation of the millimeter wave is small or the direction and polarization plane of the antenna of the wireless device installed in the camera apparatus. However, there is a problem that it is difficult for a user who is not familiar with the millimeter wave communication technology to adjust these positions and angles to a suitable one.

 そこで、本開示は、ミリ波帯を用いた無線通信を使用して画像情報を端末側装置でダウンロードする場合に、カメラ側装置と端末側装置との間の伝搬損失を抑制できるカメラ側装置、画像情報ダウンロードシステム及び画像情報ダウンロード方法を提供することを目的とする。 Therefore, the present disclosure relates to a camera-side device capable of suppressing propagation loss between the camera-side device and the terminal-side device when the terminal-side device downloads image information using wireless communication using a millimeter wave band. An object of the present invention is to provide an image information download system and an image information download method.

If it is, the terminal device downloads image information obtained by photographing with a camera via wireless communication. Therefore, when image information is downloaded by the terminal device using wireless communication using the millimeter wave band, propagation loss between the camera device and the terminal device can be suppressed, so downloading in a stable communication environment It can be performed.

 本開示のカメラ側装置の一態様として例えば、前記無線通信は第1の無線通信であり、前記端末側装置が前記推奨ダウンロードエリア内に存在していない場合には、前記推奨ダウンロードエリアに関する情報を、前記第1の無線通信とは異なる第2の無線通信を介して前記端末側装置に通知する情報通知部を更に備える。 As one aspect of the camera-side device of the present disclosure, for example, when the wireless communication is the first wireless communication and the terminal-side device does not exist in the recommended download area, information on the recommended download area is The information processing apparatus further includes an information notification unit configured to notify the terminal device via a second wireless communication different from the first wireless communication.

 上記構成によれば、第1の無線通信とは異なる第2の無線通信を使用して、端末側装置に推奨ダウンロードエリアに関する情報を通知するので、端末側装置を推奨ダウンロードエリアまで誘導することができる。したがって、第1の無線通信が使用できない環境であっても、第2の無線通信を利用して端末側装置を推奨ダウンロードエリアへ誘導することができる。 According to the above configuration, since the terminal device is notified of information on the recommended download area using the second wireless communication different from the first wireless communication, the terminal device can be guided to the recommended download area it can.

 本開示のカメラ側装置の一態様として例えば、前記第1の無線通信は、前記第2の無線通信よりも通信可能なエリアが狭く、かつ、高速通信が可能である。 As one aspect of the camera-side device of the present disclosure, for example, the first wireless communication has a narrower communicable area than the second wireless communication, and can perform high-speed communication.

 上記構成によれば、カメラ側装置は、画像を高速にダウンロードさせる目的を達成するため、第1の無線通信および第2の無線通信それぞれを補完的に利用することができる。すなわち、比較的容量の小さい推奨ダウンロードエリアに関する情報を第2の無線通信によってダウンロードさせることで、端末側装置が推奨ダウンロードエリアから大きく外れた場所に存在していても確実に推奨ダウンロードエリアまで誘導することができる。そして、推奨ダウンロードエリアに誘導した端末側装置に、第1の無線通信により画像情報を高速にダウンロードさせることができる。 According to the above configuration, the camera apparatus can complementarily use the first wireless communication and the second wireless communication in order to achieve the purpose of downloading the image at high speed. That is, by having the information related to the relatively small recommended download area downloaded by the second wireless communication, even if the terminal side device is present at a place greatly deviated from the recommended download area, it is surely guided to the recommended download area be able to. Then, the image data can be downloaded at high speed to the terminal side device guided to the recommended download area by the first wireless communication.

 以下、本開示を実施するための好適な実施の形態について、図面を参照して詳細に説明する。 Hereinafter, preferred embodiments for carrying out the present disclosure will be described in detail with reference to the drawings.

 図1は、本開示の一実施形態に係る画像情報ダウンロードシステム1の概略構成を示すブロック図である。また、図2は、本実施形態に係る画像情報ダウンロードシステム1を構成するカメラ側装置10と端末側装置20それぞれの概略構成を示すブロック図である。図1及び図2において、本実施形態に係る画像情報ダウンロードシステム1は、監視カメラ11、ミリ波送信機12、位置情報サーバ13及び画像認識サーバ14を有するカメラ側装置10と、ミリ波受信機21及びホスト端末22を有する端末側装置20と、を備える。 FIG. 1 is a block diagram showing a schematic configuration of an image information download system 1 according to an embodiment of the present disclosure. Moreover, FIG. 2 is a block diagram which shows schematic structure of each of the camera side apparatus 10 and the terminal side apparatus 20 which comprise the image information download system 1 which concerns on this embodiment. In FIG. 1 and FIG. 2, the image information download system 1 according to the present embodiment includes a camera side device 10 having a monitoring camera 11, a millimeter wave transmitter 12, a position information server 13 and an image recognition server 14, a millimeter wave receiver 21 and a terminal device 20 having a host terminal 22.

 〔カメラ側装置10〕
 カメラ側装置10において、監視カメラ11は、CCD(Charge Coupled Device)又はCMOS(Complementary Metal Oxide Semiconductor)等の撮像素子(図示略)を有し、監視対象エリア(図示略)を撮影して得られた画像情報をミリ波送信機12に出力する。
[Camera-side device 10]
In the camera-side device 10, the monitoring camera 11 has an imaging device (not shown) such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), and is obtained by photographing the monitoring target area (not shown). The obtained image information is output to the millimeter wave transmitter 12.

 ミリ波送信機12は、監視カメラ11から出力された画像情報を蓄積し、また蓄積した画像情報を端末側装置20に送信する(端末側装置20にダウンロードさせる)。端末側装置20における画像情報のダウンロードは、端末側装置20が推奨ダウンロードエリア107に存在しているときに行われる。また、端末側装置20に対する画像情報のダウンロードには、高速通信が可能なミリ波帯の第1の無線通信(例えばWiGig(登録商標、IEEE802.11ad)が用いられる。なお、WiGig(登録商標)の周波数帯は例えば60GHz帯である。 The millimeter wave transmitter 12 accumulates the image information output from the monitoring camera 11 and transmits the accumulated image information to the terminal device 20 (downloads it to the terminal device 20). The download of the image information in the terminal device 20 is performed when the terminal device 20 exists in the recommended download area 107. In addition, the first wireless communication in the millimeter wave band (for example, WiGig (registered trademark, IEEE802.11ad) capable of high-speed communication is used to download image information to the terminal-side device 20. Note that WiGig (registered trademark) Is a 60 GHz band, for example.

 ミリ波送信機12は、端末側装置20が推奨ダウンロードエリア107に存在している場合に画像情報の送信を行う。この際、端末側装置20が推奨ダウンロードエリア107に存在しているか否かは、端末側装置20の端末位置情報に基づいて行われる。端末側装置20にはマーカー23が設けられており、このマーカー23を監視カメラ11が撮影した画像から検出することで端末側装置20の端末位置情報が得られる。すなわち、マーカーが監視カメラ11に撮影可能であるということは、少なくともマーカーと監視カメラ11との間に遮蔽物が存在せず、かつ、端末側装置20が監視カメラ11の近傍に位置していることを意味する。また、撮影されたマーカーの大きさや、ともに撮影された周辺の地形の情報から更に具体的な端末側装置20の位置を検出することも可能である。ここで、端末側装置20に設けられたマーカー23は、画像認識サーバ14によって検出される。 The millimeter wave transmitter 12 transmits image information when the terminal device 20 exists in the recommended download area 107. At this time, whether or not the terminal device 20 exists in the recommended download area 107 is performed based on the terminal position information of the terminal device 20. A marker 23 is provided in the terminal device 20, and the terminal position information of the terminal device 20 can be obtained by detecting the marker 23 from the image captured by the monitoring camera 11. That is, the fact that the marker can be photographed by the surveillance camera 11 means that there is no shield at least between the marker and the surveillance camera 11 and the terminal device 20 is located in the vicinity of the surveillance camera 11 It means that. In addition, it is also possible to detect a more specific position of the terminal-side device 20 from the size of the photographed marker and the information of the surrounding terrain photographed together. Here, the marker 23 provided in the terminal device 20 is detected by the image recognition server 14.

 端末側装置20に設けられるマーカー23は、例えばバーコードである。なお、周知の如くバーコードには1次元のものや2次元のものがあり、特に2次元のバーコードはQRコード(登録商標)とも呼ばれている。マーカー23は、これが設けられた端末側装置20のMAC(Media Access Control)アドレス等の情報も有している。 The marker 23 provided on the terminal device 20 is, for example, a barcode. As well known, barcodes include one-dimensional and two-dimensional barcodes, and in particular, a two-dimensional barcode is also called a QR code (registered trademark). The marker 23 also has information such as a MAC (Media Access Control) address of the terminal device 20 provided with the marker 23.

 ミリ波送信機12は、マーカー23が検出された端末側装置20が推奨ダウンロードエリア107内に存在しているか否かを判定し、推奨ダウンロードエリア107内に存在していると判定した場合には、画像情報を第1の無線通信を介して端末側装置20に送信する。ミリ波送信機12は、マーカー23が検出された端末側装置20が推奨ダウンロードエリア107内に存在しているか否かの判定を、位置情報サーバ13に登録されている情報に基づいて行う。位置情報サーバ13には、推奨ダウンロードエリア107をデータベース化した推奨ダウンロード(DL)マップ130(図2参照)と、端末側装置20の位置を管理する端末位置管理テーブル131(図2参照)とが記憶されている。 The millimeter wave transmitter 12 determines whether the terminal device 20 in which the marker 23 is detected is present in the recommended download area 107, and when it is determined that the terminal device 20 is present in the recommended download area 107. , And transmits the image information to the terminal device 20 via the first wireless communication. The millimeter wave transmitter 12 determines whether the terminal device 20 in which the marker 23 is detected is present in the recommended download area 107 based on the information registered in the position information server 13. The position information server 13 includes a recommended download (DL) map 130 (see FIG. 2) as a database of the recommended download area 107 and a terminal position management table 131 (see FIG. 2) for managing the position of the terminal device 20. It is memorized.

 図3は、位置情報サーバ13に記憶された端末位置管理テーブル131の一例を示す図である。同図に示すように、端末位置管理テーブル131には、受信可能エリア106内に存在する端末側装置20のマーカー23が検出された時刻(即ち、マーカー検出時刻)、受信可能エリア106内に存在する端末側装置20の座標(即ち、エリア内端末座標)、受信可能エリア106内に存在する端末側装置20のMACアドレス等が登録されている。図3に示す例では、4台分の端末側装置20が登録されている。なお、MACアドレスは、実際には端末側装置20のホスト端末22に一意に割り当てられたものである。 FIG. 3 is a view showing an example of the terminal position management table 131 stored in the position information server 13. As shown in the figure, in the terminal position management table 131, the time at which the marker 23 of the terminal device 20 present in the receivable area 106 is detected (ie, the marker detection time) is present in the receivable area 106. Coordinates of the terminal device 20 (i.e., in-area terminal coordinates), a MAC address of the terminal device 20 present in the receivable area 106, and the like are registered. In the example shown in FIG. 3, four terminal devices 20 are registered. The MAC address is actually uniquely assigned to the host terminal 22 of the terminal device 20.

 ミリ波送信機12は、位置情報サーバ13の端末位置管理テーブル131を参照して、マーカー23が検出された端末側装置20が推奨ダウンロードエリア107内に存在しているか否かを判定する。マーカー23が検出された端末側装置20が推奨ダウンロードエリア107内に存在していないと判定した場合には、第1の無線通信よりも通信速度の遅い第2の無線通信(例えばIEEE802.11aのWi-Fi(登録商標))を介して、マーカー23が検出された端末側装置20に推奨ダウンロードエリア107に関する情報を通知する。推奨ダウンロードエリア107に関する情報は、例えば、マーカー23が検出された端末側装置20から推奨ダウンロードエリア107までの移動方向及び移動距離の情報である。 The millimeter wave transmitter 12 refers to the terminal position management table 131 of the position information server 13 and determines whether or not the terminal device 20 in which the marker 23 is detected is present in the recommended download area 107. If it is determined that the terminal device 20 in which the marker 23 is detected is not present in the recommended download area 107, the second wireless communication (for example, IEEE 802.11a) having a slower communication speed than the first wireless communication Information on the recommended download area 107 is notified to the terminal device 20 where the marker 23 is detected via Wi-Fi (registered trademark). The information on the recommended download area 107 is, for example, information on the moving direction and moving distance from the terminal device 20 at which the marker 23 is detected to the recommended download area 107.

 上記した第2の無線通信は、第1の無線通信よりも周波数が低い分、直進性が弱いため、誘導情報を第1の無線通信よりも広域に亘って送信することが可能である。即ち、端末側装置20の受信可能エリアを大きくとることかできる。なお、端末側装置20が誘導情報を受信できるエリアのことを受信可能エリア106と呼ぶ。 Since the second wireless communication described above is weak in rectilinearity because the frequency is lower than that of the first wireless communication, the guidance information can be transmitted over a wider area than the first wireless communication. That is, the receivable area of the terminal device 20 can be made large. The area where the terminal device 20 can receive the guidance information is referred to as a receivable area 106.

 ミリ波送信機12は、推奨ダウンロードエリア107に関する情報を通知した端末側装置20が推奨ダウンロードエリア107内に移動した場合には、蓄積している画像情報を端末側装置20でダウンロードする。 When the terminal device 20 notified of the information on the recommended download area 107 moves into the recommended download area 107, the millimeter wave transmitter 12 downloads the stored image information by the terminal device 20.

 監視カメラ11、ミリ波送信機12及び画像認識サーバ14は、それぞれ相互に通信できるように通信接続されている。また、ミリ波送信機12と位置情報サーバ13間も同様に通信接続されている。 The surveillance camera 11, the millimeter wave transmitter 12, and the image recognition server 14 are communicably connected to each other. Further, the communication between the millimeter wave transmitter 12 and the position information server 13 is similarly made.

 ミリ波送信機12は、図2に示すように、外部ストレージSDメモリ121と、CPU122と、内部メモリ123と、ミリ波RF部(第1の無線通信部)124と、無線通信部(第2の無線通信部)125と、ミリ波用アンテナ15と、無線通信用アンテナ16とを備える。外部ストレージSDメモリ121は、例えば不揮発性のフラッシュメモリであり、監視カメラ11で撮影して得られた画像情報を記憶する。外部ストレージSDメモリ121は、ミリ波送信機12の本体に対して着脱可能となっており、これをミリ波送信機12から取り外すことで、記憶されている画像情報をノート型パソコンやタブレット型端末等の電子機器で再生・表示することができる。 As shown in FIG. 2, the millimeter wave transmitter 12 includes an external storage SD memory 121, a CPU 122, an internal memory 123, a millimeter wave RF unit (first wireless communication unit) 124, and a wireless communication unit (second The wireless communication unit 125), the millimeter wave antenna 15, and the wireless communication antenna 16 are provided. The external storage SD memory 121 is, for example, a non-volatile flash memory, and stores image information obtained by photographing with the monitoring camera 11. The external storage SD memory 121 can be attached to and detached from the main body of the millimeter wave transmitter 12.

It is a flowchart which shows operation | movement. In the figure, "DL" means "download" and "DB" means "database".

 同図において、画像認識サーバ14は、監視カメラ11で撮影して得られた画像情報に対して画像認識処理を行い、端末側装置20に設けられたマーカー23の検出を行う。そして、マーカー23を検出した場合、ミリ波送信機12にマーカー23を検出した旨の通知を行う(ステップS01)。次いで、画像認識サーバ14は、検出したマーカー23が設けられた端末側装置20の位置情報等を算出し、位置情報サーバ13に端末位置情報等を通知する(ステップS02)。位置情報サーバ13は、画像認識サーバ14から端末位置情報等の通知を受け取ると、端末位置管理テーブル131に「端末管理No.」、「マーカー検出時刻」、「エリア内端末座標」及び「MACアドレス」等を登録する(ステップS03)。 In the figure, the image recognition server 14 performs an image recognition process on image information obtained by photographing with the monitoring camera 11 and detects a marker 23 provided on the terminal device 20. When the marker 23 is detected, the millimeter wave transmitter 12 is notified that the marker 23 has been detected (step S01). Next, the image recognition server 14 calculates position information and the like of the terminal device 20 provided with the detected marker 23, and notifies the position information server 13 of terminal position information and the like (step S02). When the position information server 13 receives a notification such as terminal position information from the image recognition server 14, the terminal position management table 131 displays “terminal management No.”, “marker detection time”, “in-area terminal coordinates”, and “MAC address Etc. are registered (step S03).

 ミリ波送信機12は、画像認識サーバ14からマーカー検知通知を受け取ると、位置情報サーバ13に推奨ダウンロードエリア107に関する情報を要求する(ステップS04)。位置情報サーバ13は、ミリ波送信機12から推奨ダウンロードエリア107に関する情報の要求を受け取ると、画像認識サーバ14から通知された端末位置情報から推奨ダウンロードエリア107をデータベース検索し、そして推奨ダウンロードエリア107の検索後、その推奨ダウンロードエリア107への移動方向と移動距離を計算する(ステップS05)。次いで、位置情報サーバ13は、端末側装置20に推奨ダウンロードエリア情報等(移動方向及び移動距離を含む)を通知するために、該推奨ダウンロードエリア情報等をミリ波送信機12に通知する(ステップS06)。次いで、位置情報サーバ13は、端末側装置20に推奨ダウンロードエリア情報等の通知が完了したことを画像認識サーバ14に報告する(ステップS07)。 When receiving the marker detection notification from the image recognition server 14, the millimeter wave transmitter 12 requests the position information server 13 for information on the recommended download area 107 (step S04). When receiving a request for information on the recommended download area 107 from the millimeter wave transmitter 12, the position information server 13 searches the database for the recommended download area 107 from the terminal position information notified from the image recognition server 14, and then the recommended download area 107 After the search, the moving direction and the moving distance to the recommended download area 107 are calculated (step S05). Next, the position information server 13 notifies the millimeter wave transmitter 12 of the recommended download area information etc. in order to notify the terminal device 20 of the recommended download area information etc. (including the moving direction and the movement distance) (step S06). Next, the position information server 13 reports to the image recognition server 14 that the terminal device 20 has been notified of the recommended download area information etc. (step S07).

 ミリ波送信機12は、位置情報サーバ13から推奨ダウンロードエリア情報等の通知を第2の無線通信を介してホスト端末22に送信する(ステップS09)。このときホスト端末22では既にアプリケーション(ミリ波送信機12の無線通信部125と無線接続するためのソフトウェアであり、ホスト端末22のOS(Operating System)上で動作する)が起動していて、ミリ波送信機12との間で第2の無線通信(Wi-Fi(登録商標))によるコネクションの確立が行われている(ステップS08)。 The millimeter wave transmitter 12 transmits a notification such as recommended download area information from the position information server 13 to the host terminal 22 via the second wireless communication (step S09). At this time, the host terminal 22 has already started the application (software for wireless connection with the wireless communication unit 125 of the millimeter wave transmitter 12 and operating on the operating system (OS) of the host terminal 22). A connection is established with the wave transmitter 12 by the second wireless communication (Wi-Fi (registered trademark)) (step S08).

 ホスト端末22は、ミリ波送信機12から送信された推奨ダウンロードエリア情報情報等の通知を受け取ると、通知を受けた推奨ダウンロードエリア情報等を用いてアプリケーション処理を行う(ステップS10)。即ち、誘導情報を整理する。ホスト端末22は、アプリケーション処理を行い、端末側装置20が推奨ダウンロードエリアに移動した後、ダウンロード開始処理を行い、ミリ波送信機12に対し、第2の無線通信(Wi-Fi(登録商標))を介して画像情報のダウンロードを要求する(ステップS11)。なお、ホスト端末22がアプリケーション処理を開始してから、ダウンロード開始処理を行うまでの間に、端末側装置20のユーザが誘導情報に従って推奨ダウンロードエリアまでに移動する。 When the host terminal 22 receives the notification of the recommended download area information and the like transmitted from the millimeter wave transmitter 12, the host terminal 22 performs application processing using the notified and recommended download area information and the like (step S10). That is, the guidance information is organized. The host terminal 22 performs an application process, and after the terminal device 20 moves to the recommended download area, performs a download start process to the millimeter wave transmitter 12 for the second wireless communication (Wi-Fi (registered trademark) Request the download of image information (step S11). The user of the terminal-side device 20 moves to the recommended download area according to the guidance information during the period from when the host terminal 22 starts the application processing to when the download start processing is performed.

 ミリ波送信機12は、ホスト端末22から画像情報のダウンロード要求を受け取ると、ミリ波送信機12内の外部ストレージSDメモリ121から画像情報を読み出して、ミリ波受信機21に画像情報を伝送する(ステップS12)。 Upon receiving the image information download request from the host terminal 22, the millimeter wave transmitter 12 reads the image information from the external storage SD memory 121 in the millimeter wave transmitter 12 and transmits the image information to the millimeter wave receiver 21. (Step S12).

 このように、本実施形態に係る画像情報ダウンロードシステム1によれば、カメラ側装置10で撮影して得られた画像情報を、第1の無線通信であるミリ波RF部124を介して端末側装置20にダウンロードする画像情報ダウンロードシステムである。カメラ側装置10は、監視カメラ11で撮影して得られた画像情報に基づきマーカー23を検出し、検出したマーカー23が設けられた端末側装置20が推奨ダウンロードエリア107内に存在しているか否かを判定し、該端末側装置20が推奨ダウンロードエリア107内に存在していない場合には、推奨ダウンロードエリア107に関する情報を、無線通信部125を介して端末側装置20に通知する。端末側装置20は、カメラ側装置10から通知された推奨ダウンロードエリア107に関する情報を用いて、端末側装置20を推奨ダウンロードエリア107内に誘導するための誘導情報をユーザに通知する。端末側装置20が推奨ダウンロードエリア107内に移動した場合には、画像情報をミリ波RF部124を介して端末側装置20にダウンロードさせる。したがって、ミリ波帯を用いた無線通信を使用して画像情報を端末側装置20にダウンロードさせる場合に、カメラ側装置10と端末側装置20との間の伝搬損失を抑制でき、安定した通信環境でダウンロードを行うことができる。 As described above, according to the image information download system 1 according to the present embodiment, the image information obtained by photographing with the camera device 10 is transmitted to the terminal side via the millimeter wave RF unit 124 which is the first wireless communication. This is an image information download system to be downloaded to the device 20. The camera side device 10 detects the marker 23 based on the image information obtained by photographing with the monitoring camera 11, and the terminal side device 20 provided with the detected marker 23 is present in the recommended download area 107 If the terminal apparatus 20 does not exist in the recommended download area 107, the terminal apparatus 20 is notified of information on the recommended download area 107 via the wireless communication unit 125. The terminal device 20 notifies the user of guidance information for guiding the terminal device 20 into the recommended download area 107 using the information on the recommended download area 107 notified from the camera device 10. When the terminal device 20 moves into the recommended download area 107, the image information is downloaded to the terminal device 20 via the millimeter wave RF unit 124. Therefore, when making the terminal device 20 download image information using wireless communication using the millimeter wave band, the propagation loss between the camera device 10 and the terminal device 20 can be suppressed, and a stable communication environment is achieved. You can download it with

 なお、上記実施形態においては、推奨ダウンロードエリア107が1つある例であったが、複数あっても構わない。この場合、複数の推奨ダウンロードエリア107のうち、端末側装置20から最も近いものを選択して、その推奨ダウンロードエリア107を端末側装置20に通知するようにしてもよい。 In the above-described embodiment, one recommendation download area 107 is provided, but a plurality of recommendation download areas 107 may be provided. In this case, among the plurality of recommended download areas 107, the one closest to the terminal device 20 may be selected, and the recommended download area 107 may be notified to the terminal device 20.

 また、上記実施形態において、ホスト端末22の無線通信部220をミリ波受信機21の方に設けても良い。 Further, in the above embodiment, the wireless communication unit 220 of the host terminal 22 may be provided on the millimeter wave receiver 21 side.

 また、上記実施形態において、ミリ波受信機21のミリ波RF部210に接続されるミリ波用アンテナ24に当該アンテナの向きを変える駆動装置(図示略)を設けて、最大受信感度が得られる向きにCPU213が駆動装置を制御するようにしても良い。このとき、ミリ波用アンテナ24の向きをホスト端末22のディスプレイに表示することも可能である。 In the above embodiment, the millimeter wave antenna 24 connected to the millimeter wave RF unit 210 of the millimeter wave receiver 21 is provided with a driving device (not shown) for changing the direction of the antenna to obtain the maximum reception sensitivity. The CPU 213 may control the drive device in the direction. At this time, it is also possible to display the direction of the millimeter wave antenna 24 on the display of the host terminal 22.

 また、上記実施形態では、カメラ側装置10は、監視カメラ11を含むものとして説明したが、これに限られるものではない。カメラ側装置10は、監視カメラ11と接続可能な別の装置として実現されても良い。 Moreover, in the said embodiment, although the camera side apparatus 10 was demonstrated as what contains the surveillance camera 11, it is not restricted to this. The camera side device 10 may be realized as another device connectable to the monitoring camera 11.

 また、上記実施形態において、推奨ダウンロードエリア107に関する情報は、推奨ダウンロードエリア107までの移動方向及び移動距離を示す情報であるものとして説明したが、これに限られるものではない。例えば、推奨ダウンロードエリア107の位置情報であってもよい。端末側装置20がGPS等によって自身の現在位置を認識することができるのであれば、端末側装置20は、推奨ダウンロードエリア107の位置情報と現在位置との差分から、推奨ダウンロードエリア107までの移動方向及び移動距離の情報を計算することができる。 In the above embodiment, the information on the recommended download area 107 is described as the information indicating the moving direction and the moving distance to the recommended download area 107, but the present invention is not limited to this. For example, the position information of the recommended download area 107 may be used. If the terminal device 20 can recognize its own current position by GPS or the like, the terminal device 20 moves to the recommended download area 107 from the difference between the position information of the recommended download area 107 and the current position. Information of direction and movement distance can be calculated.

 また、上記実施形態において、推奨ダウンロードエリア107に関する情報は、推奨される高さやアンテナ角度に関する情報を含むものとしてもよい。これは、ミリ波帯を利用した通信で伝播損失を抑えるためには高さを含む3次元的な位置やアンテナの方向などの調整も行うことが好適であるためである。なお、端末側装置20の高さやアンテナ角度は、マーカーを含む撮影画像の解析結果から得ることもできるし、あるいは、端末側装置20に設けた加速度センサ、ジャイロセンサ、高度計などといった各種のセンサから得ることもできる。 In the above embodiment, the information on the recommended download area 107 may include information on the recommended height and antenna angle. This is because it is preferable to adjust also the three-dimensional position including the height, the direction of the antenna, and the like in order to suppress the propagation loss in the communication using the millimeter wave band. The height of the terminal device 20 and the antenna angle can be obtained from the analysis result of the photographed image including the marker, or from various sensors such as an acceleration sensor, a gyro sensor, and an altimeter provided in the terminal device 20. You can also get it.

 また、上記実施形態において、端末側装置20の端末位置情報は、マーカー23の検出結果から得られていたが、これに限られるものではない。例えば、端末側装置20自身が現在位置を取得し、第2の無線通信を介してカメラ側装置10に通知するとしてもよい。この場合、カメラ側装置10は、マーカー23が検出されると端末側装置20に対して端末位置情報の送信を要求する。このようにすることで、マーカー23が、特定の周期で点滅するLEDなど、撮影結果のみからは位置等を解析しにくいマーカーであったとしても、上記実施形態と同様の動作を実現することができる。 Moreover, in the said embodiment, although the terminal positional information on the terminal side apparatus 20 was obtained from the detection result of the marker 23, it is not restricted to this. For example, the terminal device 20 may obtain the current position and notify the camera device 10 via the second wireless communication. In this case, when the marker 23 is detected, the camera-side device 10 requests the terminal-side device 20 to transmit the terminal position information. By doing this, the same operation as the above embodiment can be realized even if the marker 23 is a marker such as an LED that blinks at a specific cycle, whose position and the like are difficult to analyze only from the photographing result. it can.

 また、上記実施形態において、誘導情報はディスプレイに表示されることで通知されたが、これに限られるものではない。誘導情報をユーザが認識可能な態様で出力できるのであれば出力の態様は問わない。具体的には音声や振動などが考えられる。 Moreover, in the said embodiment, although guidance information was notified by being displayed on a display, it is not restricted to this. There is no limitation on the form of output as long as the guidance information can be output in a manner that can be recognized by the user. Specifically, voice and vibration can be considered.

 また、上記実施形態において、第1の無線通信としてWiGig(登録商標)を使用したが、これに限られるものではない。ミリ波帯のような、高速通信が可能な一方、送信機と受信機との間の相対的な位置や角度が伝播損失に影響し易い性質を持つ通信方式であれば他の通信方式であっても構わない。 Moreover, in the said embodiment, although WiGig (trademark) was used as 1st wireless communication, it is not restricted to this. Other communication methods are available as long as high-speed communication is possible, such as in the millimeter wave band, but the relative position and angle between the transmitter and receiver are likely to affect propagation loss. It does not matter.

 また、上記実施形態において、第2の無線通信としてWi-Fi(登録商標)を使用したが、これに限られるものではない。例えば、第2の無線通信は、少なくともカメラ側装置10が端末側装置20に対して推奨ダウンロードエリアに関する情報を送信することができればよいので、LTEなどのWi-Fi(登録商標)と方式の異なる無線通信であってもよい。 Moreover, in the said embodiment, although Wi-Fi (trademark) was used as 2nd wireless communication, it is not restricted to this. For example, in the second wireless communication, it is sufficient if at least the camera device 10 can transmit information on the recommended download area to the terminal device 20, so the method is different from Wi-Fi (registered trademark) such as LTE. It may be wireless communication.

 また、上記実施形態の説明に用いた各機能ブロックは、典型的には集積回路であるLSIとして実現される。これらは個別に1チップ化されてもよいし、一部または全てを含むように1チップ化されてもよい。ここでは、LSIとしたが、集積度の違いにより、IC、システムLSI、スーパーLSI、ウルトラLSIと呼称されることもある。 Further, each functional block used in the description of the above-described embodiment is typically implemented as an LSI which is an integrated circuit. These may be individually made into one chip, or may be made into one chip so as to include some or all. Although an LSI is used here, it may be called an IC, a system LSI, a super LSI, or an ultra LSI depending on the degree of integration.

 また、集積回路化の手法はLSIに限るものではなく、専用回路または汎用プロセッサで実現してもよい。LSI製造後に、プログラムすることが可能なFPGA(Field Programmable Gate Array)や、LSI内部の回路セルの接続や設定を再構成可能なリコンフィギュラブル・プロセッサーを利用してもよい。 Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. After the LSI is manufactured, a programmable field programmable gate array (FPGA) may be used, or a reconfigurable processor may be used which can reconfigure connection and setting of circuit cells in the LSI.

 さらには、半導体技術の進歩または派生する別技術によりLSIに置き換わる集積回路化の技術が登場すれば、当然、その技術を用いて機能ブロックの集積化を行ってもよい。バイオ技術の適用等が可能性としてありえる。 Furthermore, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology. The application of biotechnology etc. may be possible.
