Description

エレベーター用映像表示装置Video display for elevator
　本発明は、エレベーター用映像表示装置に関し、特にエレベーターかご又はエレベーター乗場等に設置される監視カメラ等で撮影された映像を、エレベーターかご内に設置されたモニター等に表示するエレベーター用映像表示装置に関するものである。 The present invention relates to an elevator video display device, and more particularly to an elevator video display device that displays an image taken by a surveillance camera or the like installed in an elevator car or an elevator hall on a monitor or the like installed in the elevator car. Is.
　近年、防犯意識の高まりによって、ビルや駅、エレベーター等の様々な公共施設に、監視カメラや監視レコーダーの設置が進み、特にエレベーターにおいては、閉じ込められた空間内での防犯目的に監視カメラが設置され、監視センターで監視するとともに、エレベーターかご内に設置されたモニターに表示することで犯罪を未然に防ぐ機能が一般的に普及している。 In recent years, with the growing awareness of crime prevention, surveillance cameras and recorders have been installed in various public facilities such as buildings, stations, and elevators. Especially in elevators, surveillance cameras have been installed for crime prevention purposes in confined spaces. In addition to monitoring at a monitoring center, a function for preventing crimes by displaying on a monitor installed in an elevator car is generally widespread.
　一方、エレベーターの各階に設置された複数の監視カメラの映像を、エレベーターの運転状況に合わせて切り替え、エレベーターの乗客向けに、降りる階の状況を表示するエレベーター監視装置がある（例えば、特許文献１参照）。 On the other hand, there is an elevator monitoring device that switches the images of a plurality of monitoring cameras installed on each floor of the elevator in accordance with the operation status of the elevator and displays the status of the floor to get off for elevator passengers (for example, Patent Document 1). reference).
　また、デジタル映像技術、映像圧縮技術、及び映像データ蓄積技術等が発展し、それらの技術を応用して構成する監視カメラ及び監視レコーダーシステムも急速に発展している。監視カメラ映像はハイビジョン映像となり、監視レコーダーは、ハイビジョン映像を記録、表示することに加え、複数の監視カメラ映像を一つの画面上に、同時に表示することが可能になっている。例えば、一つの画面を、４分割、９分割、又は１６分割のように分割し格子状に並べて一括表示するエレベーター監視装置がある（例えば、特許文献２参照）。 In addition, digital video technology, video compression technology, video data storage technology, etc. have been developed, and surveillance cameras and surveillance recorder systems configured by applying these technologies are also rapidly developing. The surveillance camera video becomes a high-definition video, and the surveillance recorder can simultaneously display a plurality of surveillance camera videos on one screen in addition to recording and displaying the high-definition video. For example, there is an elevator monitoring device that divides one screen into four, nine, or 16 divisions and arranges them in a grid and displays them all together (for example, see Patent Document 2).

　監視レコーダーが出力する複数の監視カメラの映像を一つの画面上に表示した映像は、デジタル映像技術の進化によって、フルハイビジョンと呼ばれる、解像度が１９２０ドット×１０８０ドットのハイビジョンモニターで表示することが可能となってきており、その解像度は、今度さらに高解像度化する傾向にある。 The video that displays the video of multiple surveillance cameras output by the surveillance recorder on one screen can be displayed on a high-definition monitor with resolution of 1920 dots × 1080 dots, called full high-definition, due to the evolution of digital video technology The resolution tends to be further increased.
　一方、エレベーターかご内に設置されるモニターは、エレベーターの乗客とモニター設置位置との関係を考慮し、例えば、５インチ程度の液晶パネルを設置して、エレベーターの乗客向けに、エレベーターの運行情報や、カメラの映像等を提供している。 On the other hand, the monitor installed in the elevator car considers the relationship between the elevator passenger and the monitor installation position, for example, installs a liquid crystal panel of about 5 inches, , Providing camera images.
　そのため、監視レコーダーが出力する複数の監視カメラの映像を一つの画面上に表示した映像を、５インチ程度のモニターに表示すると、それぞれの映像が小さくなってしまい、エレベーターの乗客にとって分かり難いという問題があった。
　また、複数の監視カメラ映像を同時に表示することができるが、どの映像がどの階の映像で、どの映像が次に停止する階の映像なのか、分かり難いという問題があった。 For this reason, when the images of multiple surveillance cameras output by the surveillance recorder are displayed on a single screen, they are displayed on a 5-inch monitor, making each image smaller and difficult for the passengers of the elevator to understand. was there.
Further, although a plurality of surveillance camera images can be displayed simultaneously, there is a problem that it is difficult to understand which image is on which floor and which image is the next floor to stop.
　本発明は、上記の課題を解決するためになされたものであり、各階に設置した監視カメラの映像を記録する監視レコーダーが出力する複数の監視カメラ映像を、エレベーターの停止階に応じて、対応する階の映像をエレベーター乗客に見え易く表示してエレベーター乗客の降車時の安全性を向上させたエレベーター用映像表示装置を提供することを目的とする。 The present invention has been made to solve the above problems, and supports a plurality of surveillance camera images output by a surveillance recorder that records surveillance camera images installed on each floor according to the stop floor of the elevator. It is an object of the present invention to provide an elevator image display device that displays an image of a floor to be easily displayed to an elevator passenger and improves safety when the elevator passenger gets off.
　上記の目的を達成する為、本発明に係るエレベーター用映像表示装置は、複数階に設置された監視カメラからの映像を監視レコーダーで格子状に並べて一つの映像として構成された映像信号を入力し、前記映像信号を複数に分割してそれぞれ分割映像信号としてメモリに記憶する映像入力分割部と、前記分割映像信号のそれぞれが、どの階の監視カメラの映像に対応しているかを示す各階映像対応表を予め記憶した各階映像対応表記憶部と、前記分割映像信号のそれぞれを前記メモリから読み出してモニターの画面に合わせて縮小し、縮小映像信号として前記メモリに記憶する映像縮小制御部と、エレベーター制御部から受信した次に停止する階を表す次停止階情報と、前記各階映像対応表とを用いて、前記次に停止する階の分割映像信号を前記メモリから読み出して縮小又は必要に応じて拡大し、縮小・拡大映像信号として前記メモリに記憶する映像縮小・拡大制御部と、前記次停止階情報及び前記各階映像対応表を用いて、前記メモリに記憶した前記縮小映像信号及び前記縮小・拡大映像信号を用いて画面配列し表示映像信号とする映像配列部と、前記表示映像信号を前記モニターに出力する映像出力部とを備えている。 In order to achieve the above object, an image display device for an elevator according to the present invention inputs a video signal configured as a single image by arranging images from surveillance cameras installed on a plurality of floors in a grid by a surveillance recorder. A video input division unit that divides the video signal into a plurality of parts and stores them in a memory as divided video signals, and each floor video corresponding to which floor monitoring camera video corresponds to each of the divided video signals Each floor video correspondence table storage unit that stores a table in advance, a video reduction control unit that reads each of the divided video signals from the memory, reduces them according to a monitor screen, and stores them in the memory as reduced video signals, an elevator The divided video signal of the next floor to be stopped using the next stop floor information received from the control unit and indicating the next floor to be stopped and the floor image correspondence table. Using the video reduction / enlargement control unit that reads out from the memory and reduces or enlarges as necessary, and stores the reduced / enlarged video signal in the memory, the next stop floor information, and the video correspondence table for each floor, the memory A video arrangement unit for arranging the screen using the reduced video signal and the reduced / enlarged video signal stored in the display and generating a display video signal, and a video output unit for outputting the display video signal to the monitor.
　本発明によれば、監視カメラ映像信号を複数に分割してそれぞれ分割映像信号とし、この分割映像信号のそれぞれをモニターの画面に合わせた縮小映像信号とし、エレベーター制御部から受信した次に停止する階を表す次停止階情報と、これら分割映像信号のそれぞれが、どの階の監視カメラの映像に対応しているかを示す各階映像対応表とを用いて、次に停止する階の分割映像信号を縮小又は必要に応じて拡大した縮小・拡大映像信号とし、次停止階情報及び各階映像対応表を用いて、縮小映像信号及び縮小・拡大映像信号を用いて画面配列し表示映像信号とてモニターに出力するように構成したので、監視カメラが設置された階のエレベーター乗場の映像が表示され、かつ、エレベーターの停止する階の映像が拡大して表示されるので、エレベーター利用者は、次に停止する階の映像、及び今後停止する階の映像を容易に確認することができる。 According to the present invention, the surveillance camera video signal is divided into a plurality of divided video signals, each of the divided video signals is reduced to a video signal that matches the monitor screen, and then stopped after being received from the elevator control unit. Using the next stop floor information indicating the floor and the floor video correspondence table indicating which floor of each of the divided video signals corresponds to the video of the surveillance camera of each floor, the divided video signal of the floor to be stopped next is obtained.

FIG.
　以下、本発明の各実施の形態によるエレベーター用映像表示装置を、上記の添付図面を参照して詳細に説明する。 Hereinafter, an elevator image display device according to each embodiment of the present invention will be described in detail with reference to the accompanying drawings.
　実施の形態１．
　本実施の形態に係るエレベーター用映像表示装置の構成を概略的に示す図１において、映像表示装置１０は、監視レコーダー１１と、映像信号ケーブルで接続されている。この映像信号ケーブルは、ハイビジョンの映像信号に対応するため、ＨＤＭＩ（Ｈｉ－Ｄｅｆｉｎｉｔｉｏｎ　Ｍｕｌｔｉｍｅｄｉａ　Ｉｎｔｅｒｆａｃｅ：登録商標）や、ＤＶＩ（Ｄｉｇｉａｌ　Ｖｉｄｅｏ　Ｉｎｔｅｒｆａｃｅ）、Ｄｉｓｐｌａｙ　Ｐｏｒｔ等の、デジタル映像信号用のケーブルが使用される。 Embodiment 1 FIG.
In FIG. 1 schematically showing the configuration of an elevator video display device according to the present embodiment, a video display device 10 is connected to a monitoring recorder 11 via a video signal cable. Since this video signal cable is compatible with high-definition video signals, digital video signal cables such as HDMI (Hi-Definition Multimedia Interface: registered trademark), DVI (Digital Video Interface), Display Port, etc. are used. .
　監視レコーダー１１は、各階に設置された複数の監視カメラ１２に接続されている。各監視カメラ１２からは、監視レコーダー１１に、撮影した映像が送信され、監視レコーダー１１では、複数の監視カメラ映像を、格子状に並べて、一つの映像信号として出力する。 The surveillance recorder 11 is connected to a plurality of surveillance cameras 12 installed on each floor. Each surveillance camera 12 transmits the captured video to the surveillance recorder 11, and the surveillance recorder 11 arranges a plurality of surveillance camera videos in a grid and outputs them as one video signal.
　監視レコーダー１１が、映像表示装置１０に出力する映像の例を図２に示す。図２において、映像の解像度は、１９２０ドット×１０８０ドットのフルハイビジョンサイズであり、１６個の領域に分割されている。分割された各映像を、“Ｖ１”～“Ｖ１６”とする。フルハイビジョンの縦横それぞれを４等分しているため、それぞれの映像の解像度は、４８０ドット×２７０ドットになる。 An example of the video output from the monitoring recorder 11 to the video display device 10 is shown in FIG. In FIG. 2, the video resolution is a full high-definition size of 1920 dots × 1080 dots and is divided into 16 areas. Each of the divided videos is referred to as “V1” to “V16”. Since the vertical and horizontal directions of full high-definition are divided into four equal parts, the resolution of each video is 480 dots × 270 dots.
　図１に戻って、エレベーター（図示せず）の運行制御を行うエレベーター制御部１３は、エレベーターが停止する階の情報や、運行方向（上下方向）等の情報を、映像表示装置１０に送信する。モニター１４は、映像表示装置１０から出力される映像を表示する。 Returning to FIG. 1, the elevator control unit 13 that controls the operation of the elevator (not shown) transmits information on the floor where the elevator stops and information such as the operation direction (vertical direction) to the video display device 10. . The monitor 14 displays the video output from the video display device 10.
　映像表示装置１０は、映像データを一時的に保存するメモリ１０１を内蔵している。映像入力分割部１０２は、監視レコーダー１１から送信される複数の監視カメラ１２の映像を一つの画面上に表示した映像（例えば、図２に示す映像）を入力し、それぞれの映像に分割し、分割映像信号としてメモリ１０１に書き込む。 The video display device 10 has a built-in memory 101 for temporarily storing video data. The video input dividing unit 102 inputs a video (for example, the video shown in FIG. 2) in which videos of the plurality of monitoring cameras 12 transmitted from the monitoring recorder 11 are displayed on one screen, and divides each video into videos. Write to the memory 101 as a divided video signal.
　図２に示すような監視レコーダー１１から入力される映像の、“Ｖ１”～“Ｖ１６”の各映像の範囲は、座標で特定することができる。
　例えば、図３は、図２に対して、座標を示した図であり、映像全体の左上を（０、０）としたとき、右上は、（１９１９、０）、左下は、（０、１０７９）、右下は、（１９１９、１０７９）になる。各映像の解像度は、４８０ドット×２７０ドットなので、例えば、図３の“Ｖ１”の映像は、（０、０）、（４７９、０）、（０、２６９）、（４７９、２６９）の４つの座標で囲まれる領域になる。 The range of each video of “V1” to “V16” of the video input from the monitoring recorder 11 as shown in FIG. 2 can be specified by coordinates.
For example, FIG. 3 is a diagram showing coordinates with respect to FIG. 2. When the upper left of the entire image is (0, 0), the upper right is (1919, 0) and the lower left is (0, 1079). ), The lower right is (1919, 1079). Since the resolution of each video is 480 dots × 270 dots, for example, the video of “V1” in FIG. 3 is 4 (0, 0), (479, 0), (0, 269), (479, 269). It becomes an area surrounded by two coordinates.
　同様に、“Ｖ２”～“Ｖ１５”についても、座標で特定され、映像入力分割部１０２は、監視レコーダー１１から入力された映像を、座標を用いて各映像に分割し、分割映像信号として、メモリ１０１に書き込む。
　なお、例として、監視レコーダー１１から送信される映像の分割数が１６の場合を説明したが、４分割や９分割等、他の分割数でも、座標を指定することで分割することができることは言うまでもない。 Similarly, “V2” to “V15” are also specified by coordinates, and the video input dividing unit 102 divides the video input from the monitoring recorder 11 into each video using the coordinates, and as divided video signals, Write to the memory 101.
As an example, the case where the number of divisions of the video transmitted from the surveillance recorder 11 is 16 has been described. However, it is possible to divide by specifying the coordinates even with other division numbers such as 4 divisions and 9 divisions. Needless to say.
　各階映像対応表記憶部１０３は、監視レコーダー１１から入力された映像を分割した時に、各分割映像信号が、どの階の監視カメラ１２の映像かを対応付ける、図４に示した各階映像対応表を記憶している。
　すなわち、図２に示す映像“Ｖ１”～“Ｖ１６”は、監視レコーダー１１から入力された映像の分割映像信号の領域を示しており、これらの分割映像信号が、それぞれどこの映像なのかを特定するため、図４に示す各階映像対応表では、分割映像信号領域２０１とカメラ設置場所２０２とを対応付けるとともに、これらにさらにエレベーター停止階情報２０３によって、エレベーター制御部１３から送信される停止階情報を関連付けている。 Each floor image correspondence table storage unit 103 associates each floor image correspondence table shown in FIG. 4 with which each divided image signal corresponds to the image of the surveillance camera 12 when dividing the image input from the surveillance recorder 11. I remember it.
That is, the videos “V1” to “V16” shown in FIG. 2 indicate the areas of the divided video signals of the video input from the surveillance recorder 11, and specify which video each of these divided video signals is. Therefore, in each floor video correspondence table shown in FIG. 4, the divided video signal area 201 and the camera installation location 202 are associated with each other, and the stop floor information transmitted from the elevator control unit 13 is further added to these by the elevator stop floor information 203. It is related.
　このエレベーター停止階情報２０３は、例えば、エレベーター制御部１３から送信されるエレベーターの停止階情報と同じか否かの判断に使用される。例えば、分割映像信号領域２０１の“Ｖ１”は、カメラ設置場所２０２が“１階乗場”で、エレベーター停止階情報２０３が１階を示す“１階”であるとすると、エレベーター制御部１３からの停止階情報が、エレベーターが１階に到着したこと、又は到着予定であることを知らせる時などに、エレベーター停止階情報２０３の“１階”を参照して、それに対応する“Ｖ１”の映像を用いて表示などを行う。 The elevator stop floor information 203 is used, for example, for determining whether or not the elevator stop floor information is the same as the elevator stop floor information transmitted from the elevator control unit 13. For example, if “V1” in the divided video signal area 201 is “1st floor hall” where the camera installation location 202 is “1st floor”, and the elevator stop floor information 203 is “1st floor” indicating the 1st floor, the elevator control unit 13 When the stop floor information informs that the elevator has arrived or is scheduled to arrive on the first floor, refer to the “first floor” of the elevator stop floor information 203 and display the corresponding video of “V1”. Use to display.
　図１に戻り、映像縮小制御部１０４は、エレベーター制御部１３から送信される停止階情報と、各階映像対応表記憶部１０３に記憶されている各階映像対応表における、エレベーター停止階情報２０３及び分割映像信号領域２０１の情報を用いて、後述するように、映像解像度記憶部１０９の記憶情報に基づき、メモリ１０１に書き込まれた分割映像信号をモニター１４の画面サイズに合わせて縮小し、かつ必要に応じてアスペクト比の違いに対応するためのトリミング処理や、上下黒帯の挿入処理を行い、縮小映像信号としてメモリ１０１に書き込むものである。 Returning to FIG. 1, the video reduction control unit 104 includes the stop floor information transmitted from the elevator control unit 13 and the elevator stop floor information 203 and the division in each floor video correspondence table stored in each floor video correspondence table storage unit 103. Using the information in the video signal area 201, as described later, the divided video signal written in the memory 101 is reduced in accordance with the screen size of the monitor 14 based on the storage information in the video resolution storage unit 109, and necessary. Accordingly, a trimming process to cope with a difference in aspect ratio and an insertion process of upper and lower black bands are performed, and a reduced video signal is written in the memory 101.
　映像縮小・拡大制御部１０５は、エレベーター制御部１３から送信される次に停止する階の情報と、各階映像対応表記憶部１０３に記憶されている各階映像対応表における、エレベーター停止階情報２０３及び分割映像信号領域２０１の情報を用いて、メモリ１０１に書き込まれた分割映像信号をさらに縮小し、必要に応じて拡大し、また必要に応じて、アスペクト比の違いに対応するためのトリミング処理や、上下黒帯の挿入処理を行い、縮小・拡大映像信号としてメモリ１０１に書き込むものである。
　なお、「縮小・拡大」という表現は、「縮小し、必要に応じて拡大する」という意味であり、これについては、追って説明する。 The video reduction / enlargement control unit 105 includes information on the next floor to be stopped transmitted from the elevator control unit 13, elevator stop floor information 203 in each floor video correspondence table stored in each floor video correspondence table storage unit 103, and Using the information of the divided video signal area 201, the divided video signal written in the memory 101 is further reduced, enlarged as necessary, and, if necessary, a trimming process for dealing with a difference in aspect ratio, The upper and lower black bands are inserted and written into the memory 101 as a reduced / enlarged video signal.
The expression “reduction / enlargement” means “reduction and enlargement as necessary”, which will be described later.
　この映像縮小・拡大制御部１０５で生成される縮小・拡大映像信号は、エレベーターが次に停止する階の映像を、モニター１４で大きく表示するように生成されたものである。そのため、分割映像信号を、モニター１４の解像度及び分割映像信号の解像度によって、縮小又は必要に応じて拡大して、アスペクト比の違いに対応するためのトリミング処理や、上下黒帯の挿入処理を行い、縮小・拡大映像信号として生成する。 The reduction / enlargement video signal generated by the video reduction / enlargement control unit 105 is generated so that the monitor 14 displays a video image of the next floor where the elevator stops. Therefore, the divided video signal is reduced or enlarged as necessary according to the resolution of the monitor 14 and the resolution of the divided video signal, and trimming processing and insertion processing of upper and lower black bands are performed to cope with the difference in aspect ratio. And generated as a reduced / enlarged video signal.
　映像加工部１０６は、エレベーター制御部１３から送信される停止階情報と、各階映像対応表記憶部１０３に記憶されているエレベーター停止階情報２０３及び分割映像信号領域２０１の情報とを用いて、メモリ１０１に書き込まれた縮小映像信号のうち、エレベーターが停止しない階の縮小映像信号の、輝度を下げる、色成分を除去する、モザイク加工する、又は網掛けする等の加工を行い、縮小加工映像信号としてメモリ１０１に書き込むものである。これについても後述する。 The video processing unit 106 uses the stop floor information transmitted from the elevator control unit 13 and the elevator stop floor information 203 and the information of the divided video signal area 201 stored in each floor video correspondence table storage unit 103 to store the memory. Of the reduced video signal written in 101, the reduced video signal of the floor where the elevator does not stop is subjected to processing such as lowering the brightness, removing the color component, mosaic processing, or shading, etc. Are written in the memory 101. This will also be described later.
　映像配列部１０７は、エレベーター制御部１３から送信される停止階情報及び次に停止する階の情報と、各階映像対応表記憶部１０３に記憶されているエレベーター停止階情報２０３及び分割映像信号領域２０１の情報とを用いて、次に停止する階の縮小・拡大映像信号と、次に停止する階以外の縮小映像信号、及び縮小加工映像信号を、メモリ１０１から読み出して、画面配列した表示映像信号として構成し、メモリ１０１に書き込むものである。 The video arrangement unit 107 includes stop floor information transmitted from the elevator control unit 13 and information on the next floor to stop, elevator stop floor information 203 and divided video signal areas 201 stored in each floor video correspondence table storage unit 103. The reduced / enlarged video signal of the next floor to be stopped, the reduced video signal other than the next floor to be stopped, and the reduced processed video signal are read from the memory 101 and displayed on the screen. And is written in the memory 101.
　すなわち、映像配列部１０７では、次に停止する階の映像は、縮小・拡大映像信号を用いて大きく表示し、それ以外の階については、縮小映像信号や、縮小加工映像信号を用いて小さく表示する。表示例については、動作例で後述する。 That is, in the video arrangement unit 107, the next floor image to be stopped is displayed large using the reduced / enlarged video signal, and the other floors are displayed smaller using the reduced video signal or the reduced processed video signal. To do. A display example will be described later in an operation example.
　映像出力部１０８は、エレベーター制御部１３から送信されるエレベーター運行情報を用いて、メモリ１０１に書き込まれた表示映像信号を読み出して、モニター１４に出力するものである。 The video output unit 108 reads the display video signal written in the memory 101 using the elevator operation information transmitted from the elevator control unit 13 and outputs it to the monitor 14.
　また、映像解像度記憶部１０９は、監視レコーダー１１から入力される映像の全体解像度、分割数、モニター１４の全体の解像度、縮小映像の解像度、縮小・拡大映像の解像度、並びに、縮小映像及び縮小・拡大映像を生成するときのアスペクト比の処理方法を記憶したものである。 The video resolution storage unit 109 also receives the overall resolution and the number of divisions of the video input from the monitoring recorder 11, the overall resolution of the monitor 14, the resolution of the reduced video, the resolution of the reduced / enlarged video, and the reduced video and the reduced / reduced video / video. The aspect ratio processing method for generating an enlarged image is stored.
　次に、動作例について説明する。
　監視レコーダー１１からは、図２に示すような複数の監視カメラ１２の映像を一つの画面上に表示した映像が出力されており、映像表示装置１０の映像入力分割部１０２で、各映像に分割し、分割映像信号として、メモリ１０１に書き込む。 Next, an operation example will be described.
The monitoring recorder 11 outputs a video in which videos of a plurality of monitoring cameras 12 as shown in FIG. 2 are displayed on one screen, and the video input dividing unit 102 of the video display device 10 divides the video into each video. Then, it is written into the memory 101 as a divided video signal.
　この時、映像入力分割部１０２では、入力される映像の構成、すなわち監視レコーダー１１から出力される映像の全体の解像度と、どのように分割可能かについては、映像解像度記憶部１０９に記憶されており、例えば、解像度がフルハイビジョンの１９２０ドット×１０８０ドット、分割数が１６であれば、それに対応した座標を用いて、図２に示すように分割を行い、分割映像信号としてメモリ１０１に書き込む。
　このとき、各階映像対応表記憶部１０３に記憶されている各階映像対応表に従って、メモリ１０１に書き込まれた各分割映像信号が、どの階の映像かを関連付けることができる。 At this time, the video input dividing unit 102 stores the configuration of the input video, that is, the overall resolution of the video output from the monitoring recorder 11 and how it can be divided, in the video resolution storage unit 109. For example, if the resolution is 1920 dots × 1080 dots with full high-definition and the number of divisions is 16, division is performed as shown in FIG. 2 using the corresponding coordinates, and the divided video signals are written in the memory 101.
At this time, according to each floor image correspondence table stored in each floor image correspondence table storage unit 103, it is possible to correlate to which floor each divided image signal written in the memory 101 is an image.
　また、監視レコーダー１１では、エレベーターの乗場以外に設置された監視カメラの映像を記録することもあるため、図４の各階映像対応表のエレベーター停止階情報２０３において、例えば、“×”と記載されているところは、エレベーター制御部１３から送信される停止階情報とは連動しない。このことから、監視レコーダー１１が一般的なレコーダーであって、エレベーターとは関係の無い映像が記録・表示されていたとしても、各階映像対応表のエレベーター停止階情報２０３に“×”と記載されていれば、使用しないように構成することができる。 In addition, since the surveillance recorder 11 may record a video of a surveillance camera installed outside the elevator landing, for example, “x” is described in the elevator stop floor information 203 of each floor video correspondence table in FIG. Is not linked to the stop floor information transmitted from the elevator control unit 13. For this reason, even if the monitoring recorder 11 is a general recorder and a video not related to the elevator is recorded and displayed, “x” is described in the elevator stop floor information 203 of the video correspondence table on each floor. If so, it can be configured not to use.
　次に、映像縮小制御部１０４、映像縮小・拡大制御部１０５、及び映像加工部１０６は、エレベーター制御部１３から送信される、エレベーターの停止階情報及び次に停止する階の情報を受信して、以下の各映像信号を生成する。 Next, the image reduction control unit 104, the image reduction / enlargement control unit 105, and the image processing unit 106 receive the elevator stop floor information and the next stop floor information transmitted from the elevator control unit 13. The following video signals are generated.
　まず、映像縮小制御部１０４は、メモリ１０１に書き込まれている図２の分割映像信号を、エレベーター制御部１３から送信される停止階情報と、各階映像対応表記憶部１０３に記憶されている各階映像対応表を用いて、停止する階の分割映像を縮小して縮小映像信号を生成し、メモリ１０１に書き込む。なお、停止する階とは、エレベーターが停止することができる階のことで、例えば、階は有るが、エレベーターは停止しないか、あるいはドアがなくて停止できない階等については含まないものとする。 First, the video reduction control unit 104 converts the divided video signal of FIG. 2 written in the memory 101 into stop floor information transmitted from the elevator control unit 13 and each floor stored in each floor video correspondence table storage unit 103. Using the video correspondence table, the divided video of the floor to be stopped is reduced to generate a reduced video signal, which is written in the memory 101. The floor to be stopped is a floor where the elevator can be stopped. For example, there is a floor, but the elevator does not stop or does not include a floor that cannot be stopped without a door.
　ここで、生成する縮小映像信号の解像度は、映像解像度記憶部１０９に記憶されている。すなわち、縮小映像信号の解像度は、映像配列部１０７で画面配列するときに使用する映像の解像度であり、例えば、モニター１４の解像度が、３２０ドット×２４０ドットとして、横に４つの縮小映像を並べる場合、一つの縮小映像信号は、８０ドット×６０ドットになる。また、５つ並べる場合は、６４ドット×４８ドットとなる。これら、モニター１４の解像度、縮小映像を並べる数、及びメモリ１０１に書き込まれている分割映像信号の解像度については、予め映像解像度記憶部１０９に記憶させておくことで、映像縮小制御部１０４はそれを参照して縮小率を決めることができる。 Here, the resolution of the reduced video signal to be generated is stored in the video resolution storage unit 109. That is, the resolution of the reduced video signal is the resolution of the video used when the video arrangement unit 107 arranges the screen. For example, the resolution of the monitor 14 is 320 dots × 240 dots, and four reduced videos are arranged horizontally. In this case, one reduced video signal is 80 dots × 60 dots. When five are arranged, the size is 64 dots × 48 dots. The resolution of the monitor 14, the number of reduced videos arranged, and the resolution of the divided video signal written in the memory 101 are stored in the video resolution storage unit 109 in advance, so that the video reduction control unit 104 The reduction ratio can be determined with reference to FIG.
　また、監視レコーダー１１は、フルハイビジョンの解像度で出力し、そのアスペクト比は、１６：９になっており、各分割映像のアスペクト比も、１６：９になっている。
　一方、モニター１４は、アスペクト比として、１６：９のモニターの他、上記の３２０ドット×２４０ドットのように、４：３のモニターもある。 The surveillance recorder 11 outputs at full high-definition resolution, the aspect ratio is 16: 9, and the aspect ratio of each divided video is 16: 9.
On the other hand, the monitor 14 has an aspect ratio of 4: 3 as well as a monitor of 16: 9, such as the above-mentioned 320 dots × 240 dots.
　そのため、映像縮小制御部１０４では、アスペクト比の違いに対応するために、１６：９の映像の両端を削除して、４：３のアスペクト比にするトリミング処理や、１６：９の映像の上下に黒帯を追加して、４：３のアスペクト比にする上下黒帯追加処理を併せて行う。
　アスペクト比１６：９である４８０ドット×２７０ドットの分割映像を、アスペクト比４：３である３６０ドット×２７０ドットにするためのトリミング処理の例を図５に示す。図５に示す通り、両端それぞれ、６０ドット×２７０ドット分の映像データ（図５の３０１、３０２）が削除され、３６０ドット×２７０ドット分の映像データ（図５の３０３）のみを表示する。 Therefore, in order to cope with the difference in aspect ratio, the video reduction control unit 104 deletes both ends of the 16: 9 video to make the aspect ratio 4: 3, and the top and bottom of the 16: 9 video. A black band is added to the top and bottom black band addition processing to obtain an aspect ratio of 4: 3.
FIG. 5 shows an example of trimming processing for converting a divided image of 480 dots × 270 dots having an aspect ratio of 16: 9 into 360 dots × 270 dots having an aspect ratio of 4: 3. As shown in FIG. 5, video data for 60 dots × 270 dots (301 and 302 in FIG. 5) is deleted at both ends, and only video data for 360 dots × 270 dots (303 in FIG. 5) is displayed.
　或いは、アスペクト比１６：９である４８０ドット×２７０ドットの分割映像を、アスペクト比４：３である４８０ドット×３６０ドットにする上下黒帯追加処理の例を図６に示す。図６に示す通り、上下それぞれ、４８０ドット×４５ドットの映像データ（図６の３１１、３１２）が追加される。 Alternatively, FIG. 6 shows an example of upper and lower black band addition processing for converting a divided image of 480 dots × 270 dots having an aspect ratio of 16: 9 into 480 dots × 360 dots having an aspect ratio of 4: 3. As shown in FIG. 6, 480 dots × 45 dots of video data (311 and 312 in FIG. 6) are added on the upper and lower sides, respectively.
　このアスペクト比の違いに対応する処理方法として、トリミング処理を行うか、上下黒帯追加処理を行うかについては、映像解像度記憶部１０９に予め記憶しておき、これを映像縮小制御部１０４が参照して処理を行うことになる。 As a processing method corresponding to the difference in aspect ratio, whether to perform trimming processing or upper / lower black band addition processing is stored in advance in the video resolution storage unit 109 and is referred to by the video reduction control unit 104. Process.
　次に、映像縮小・拡大制御部１０５は、メモリ１０１に書き込まれている図２の分割映像信号を、エレベーター制御部１３から送信される次に停止する階を表す次停止階情報と、各階映像対応表記憶部１０３に記憶されている各階映像対応表とを用いて、次に停止する階の分割映像信号を縮小・拡大して、縮小・拡大映像信号を生成し、メモリ１０１に書き込む。 Next, the video reduction / enlargement control unit 105 transmits the divided video signal in FIG. 2 written in the memory 101 to the next stop floor information indicating the next floor to be stopped transmitted from the elevator control unit 13, and each floor video. Using the floor video correspondence table stored in the correspondence table storage unit 103, the divided video signal of the floor to be stopped next is reduced / enlarged to generate a reduced / enlarged video signal, which is written in the memory 101.
　また、映像縮小制御部１０４での処理と同様に、必要に応じて、映像解像度記憶部１０９に記憶されているアスペクト比の処理方法に従って、１６：９の映像の両端を削除して４：３のアスペクト比にするトリミング処理、又は１６：９の映像の上下に黒帯を追加して４：３のアスペクト比にする上下黒帯追加処理を併せて行う。 Similarly to the processing in the video reduction control unit 104, if necessary, both ends of the 16: 9 video are deleted in accordance with the aspect ratio processing method stored in the video resolution storage unit 109 and 4: 3. In addition, a trimming process for adjusting the aspect ratio of 16: 9 or a black band adding process for adding an upper and lower black band to the aspect ratio of 4: 3 by adding black bands to the top and bottom of the 16: 9 image is performed.
　ここで生成する縮小・拡大映像信号の解像度は、映像解像度記憶部１０９に記憶されている。すなわち、縮小・拡大映像信号の解像度は、映像配列部１０７で配列するときに使用する映像の解像度であり、例えば、モニター１４の解像度が、３２０ドット×２４０ドットとして、横を４分割、縦を４分割して、Ｌ字型に縮小映像を並べて、縮小・拡大映像を、縮小映像の横３つ分、縦３つ分の映像として表示する場合、２４０ドット×１８０ドットになる。 The resolution of the reduced / enlarged video signal generated here is stored in the video resolution storage unit 109. That is, the resolution of the reduced / enlarged video signal is the resolution of the video used when arranging in the video array unit 107. For example, the resolution of the monitor 14 is 320 dots × 240 dots, the horizontal is divided into four, and the vertical is When the reduced video is divided into four and arranged in an L shape, and the reduced / enlarged video is displayed as video for three horizontal and three vertical video, the size is 240 dots × 180 dots.
　この時の表示例を、図７に示す。図７において、縮小映像“Ｓ１”、“Ｓ２”、“Ｓ４”～“Ｓ８”は、それぞれ、図２における原映像“Ｖ１”、“Ｖ２”、“Ｖ４”～“Ｖ８”に対応しており、図７の映像“Ｌ３”は、図２における“Ｖ３”の拡大映像である。図２の各分割映像サイズは、４８０ドット×２７０ドットであり、縮小映像のサイズは、横に４つ配列しているので、一つの縮小映像は、解像度が８０ドット×６０ドットになる。拡大映像Ｌ３は、縮小映像の３つ分になるので、２４０ドット×１８０ドットになり、元の分割映像の解像度４８０ドット×２７０ドットから、２４０ドット×１８０ドットになるように、映像縮小・拡大制御部１０５で、縮小処理と、トリミング処理又は上下黒帯追加処理を行う。 Figure 7 shows a display example at this time. In FIG. 7, the reduced images “S1”, “S2”, “S4” to “S8” correspond to the original images “V1”, “V2”, and “V4” to “V8” in FIG. 2, respectively. The video “L3” in FIG. 7 is an enlarged video of “V3” in FIG. Each divided video size in FIG. 2 is 480 dots × 270 dots, and four reduced video sizes are arranged horizontally, so that one reduced video has a resolution of 80 dots × 60 dots. Since the enlarged video L3 corresponds to three reduced videos, the video is reduced to 240 dots x 180 dots, and the original divided video resolution is reduced from 240 dots x 270 dots to 240 dots x 180 dots. The control unit 105 performs reduction processing, trimming processing, or upper and lower black band addition processing.
　また、モニター１４の解像度が、８００ドット×６００ドットで、図７と同様の配列をした場合、縮小映像（“Ｓ１”、“Ｓ２”等）は、２００ドット×１５０ドット、拡大映像（“Ｌ３”）は、６００ドット×４５０ドットとなる。従って、拡大映像Ｌ３については、元の分割映像の解像度４８０ドット×２７０ドットよりも拡大させる必要がある。この「拡大」もモニター１４の画面の大きさや解像度によっては「縮小」になるが（これが大半である）、上記のように、時には「拡大」にもなるという意味で、「縮小・拡大」という表現がここでは使用されている。 When the resolution of the monitor 14 is 800 dots × 600 dots and the arrangement is the same as in FIG. 7, the reduced image (“S1”, “S2”, etc.) is 200 dots × 150 dots, and the enlarged image (“L3”). “)” Is 600 dots × 450 dots. Therefore, the enlarged video L3 needs to be enlarged more than the resolution 480 dots × 270 dots of the original divided video. This “enlargement” is also “reduction” depending on the size and resolution of the screen of the monitor 14 (which is the majority), but as described above, it is sometimes referred to as “reduction / enlargement” in the sense that it also becomes “enlargement”. The expression is used here.
　このように、モニター１４の解像度、縮小映像を並べる数、及び縮小・拡大映像の解像度については、予め決めることができ、メモリ１０１に書き込まれている分割映像信号の解像度とともに、映像解像度記憶部１０９に記憶させておくことで、映像縮小・拡大制御部１０５はそれを参照し、拡大率又は縮小率を決めることができる。 As described above, the resolution of the monitor 14, the number of reduced videos arranged, and the resolution of the reduced / enlarged video can be determined in advance, and the video resolution storage unit 109 together with the resolution of the divided video signal written in the memory 101. Thus, the image reduction / enlargement control unit 105 can determine the enlargement rate or reduction rate by referring to the stored information.
　次に、映像加工部１０６は、メモリ１０１に書き込まれている縮小映像信号を、エレベーター制御部１３から送信される停止階情報と、停止する予定の停止予定階情報と、各階映像対応表記憶部１０３に記憶されている各階映像対応表とを用いて、エレベーターが停止しない階の縮小映像信号の、輝度を下げる、色成分を除去する、モザイク加工する、又は網掛けする等の加工を行い、縮小加工映像信号としてメモリ１０１に書き込む。 Next, the video processing unit 106 transmits the reduced video signal written in the memory 101 to the stop floor information transmitted from the elevator control unit 13, the planned stop floor information to be stopped, and the floor video correspondence table storage unit. Using the floor image correspondence table stored in 103, the reduced video signal of the floor where the elevator does not stop, such as reducing the brightness, removing the color component, mosaic processing, or shading, etc., Write to the memory 101 as a reduced processed video signal.
　上記の輝度を下げる処理は、縮小映像信号の輝度信号を一律に下げることで、暗くなった映像とする。
　上記の色成分を除く処理は、縮小映像信号の色度信号をゼロとすることで、白黒映像とする。
　上記のモザイク加工処理は、縮小映像信号を、例えば、８ドット×８ドット単位で平均化して、元の映像からは、ぼかした映像とする。
　上記の網掛け処置は、既存の模様を縮小映像信号に重ねる処理であり、元の映像を確認し難くなる映像となる。 In the above-described process for reducing the luminance, the luminance signal of the reduced video signal is uniformly reduced to obtain a darkened image.
The processing for removing the color components described above makes a black and white video by setting the chromaticity signal of the reduced video signal to zero.
In the above mosaic processing, the reduced video signal is averaged, for example, in units of 8 dots × 8 dots, and the original video is blurred.
The above-described shading process is a process of overlaying an existing pattern on the reduced video signal, and the video becomes difficult to confirm the original video.
　映像配列部１０７では、エレベーター制御部１３から送信されるエレベーターの停止階情報、次に停止する階の次停止階情報、及び停止する予定の停止予定階情報を受信して、各階映像対応表記憶部１０３に記憶されているエレベーター停止階情報２０３と分割映像信号領域２０１の情報とを用いて、メモリ１０１に書き込まれている縮小映像信号、縮小・拡大映像信号、及び縮小加工映像信号を用いて、モニター１４に表示するための映像の配列を行い、表示映像信号としてメモリ１０１に書き込む。 In the video arrangement unit 107, the elevator stop floor information transmitted from the elevator control unit 13, the next stop floor information of the next floor to stop, and the planned stop floor information to be stopped are received, and each floor video correspondence table is stored. Using the elevator stop floor information 203 stored in the unit 103 and the information of the divided video signal area 201, the reduced video signal, the reduced / enlarged video signal, and the reduced processed video signal written in the memory 101 are used. Then, the video to be displayed on the monitor 14 is arranged and written in the memory 101 as a display video signal.
　図８は、エレベーターが上昇方向に運行して、“３階”に到着する前の表示例である。映像“Ｌ３”は、図４に示す各階映像対応表の、各エレベーター停止階情報２０３から、“３階”のエレベーター乗場に設置された監視カメラの映像であり、縮小映像“Ｓ１”、“Ｓ２”、及び“Ｓ４”～“Ｓ８”は、それぞれ、“１階”、“２階”、及び“４階”～“８階”のエレベーター乗場に設置された監視カメラの映像である。また、縮小映像“Ｓ１”及び“Ｓ２”については、エレベーターは、次の停止階が“３階”になっていて、“１階”及び“２階”には到着しないので、映像加工部１０６で加工された縮小加工映像信号を用いる。 FIG. 8 is a display example before the elevator operates in the upward direction and arrives at the “3rd floor”. The video “L3” is a video of the surveillance camera installed at the elevator landing on the “3rd floor” from each elevator stop floor information 203 in each floor video correspondence table shown in FIG. 4, and reduced video “S1”, “S2” "And" S4 "to" S8 "are images of surveillance cameras installed at the elevator landings of" 1st floor "," 2nd floor ", and" 4th floor "to" 8th floor ", respectively. For the reduced images “S1” and “S2”, the elevator has the next stop floor as “3rd floor” and does not arrive at “1st floor” and “2nd floor”. The reduced processed video signal processed in step 1 is used.
　また、エレベーター制御部１３から送信されるエレベーターの停止階情報で、例えば、縮小映像“Ｓ５”及び“Ｓ７”にそれぞれ対応する“５階”及び“７階”に停止しない場合は、縮小映像“Ｓ５”及び“Ｓ７”についても、縮小加工映像信号を用いる。それ以外の縮小映像は、縮小映像信号を使用する。なお、図８では、縮小加工映像信号の表示については、“Ｓ１”の部分のように、グレー色で表現する。なお、このグレー色は図面では斜線部で示されている。また、以降の図においても同様に、縮小加工映像信号の表示については、グレー色（斜線部）で表現する。 Further, when the elevator stop floor information transmitted from the elevator control unit 13 does not stop at “5th floor” and “7th floor” respectively corresponding to the reduced images “S5” and “S7”, for example, the reduced image “ The reduced processed video signal is also used for S5 "and" S7 ". The other reduced video uses a reduced video signal. In FIG. 8, the display of the reduced processed video signal is expressed in gray as in the portion “S1”. This gray color is indicated by hatching in the drawing. Similarly, in the subsequent drawings, the display of the reduced processed video signal is expressed in gray (hatched portion).
　また、別の表示例として、図９に示すように、エレベーターが上昇方向に運転しているときに、次に“３階”に到着する場合は、“４階”より上の階のエレベーター乗場に設置された監視カメラの映像のみ表示するように構成してもよい。
　図９では、“５階”、“７階”、及び“１０階”には停止しない例を示しており、映像“Ｓ５”、“Ｓ７”、及び“Ｓ１０”は、縮小加工映像信号を用い、それ以外の縮小映像は、縮小映像信号を使用する。 As another display example, as shown in FIG. 9, when the elevator is operating in the upward direction, if it arrives at “3rd floor” next, the elevator hall on the floor above “4th floor” It may be configured to display only the video of the surveillance camera installed in the.
FIG. 9 shows an example in which “5th floor”, “7th floor”, and “10th floor” do not stop, and the video “S5”, “S7”, and “S10” use reduced processed video signals. For other reduced video, the reduced video signal is used.
　さらに、エレベーターの運行範囲が、“１階”から“１５階”までとした場合、上昇方向に運転していて、“９階”に到着するときには、図１０に示すように、最上階（１５階）まで表示するように構成してもよい。 Furthermore, when the elevator operating range is from “1st floor” to “15th floor”, when driving up and arriving at “9th floor”, as shown in FIG. (Floor) may be displayed.
　図１０は、“９階”に停止するときの例を示しており、“Ｌ９”は、“９階”の拡大映像信号であり、既に通過した“８階”のエレベーター乗場に設置された監視カメラの縮小映像である“Ｓ８”と、停止しない予定である“１０階”及び“１４階”のエレベーター乗場に設置された監視カメラの縮小映像である“Ｓ１０”及び“Ｓ１４”は、縮小加工映像信号を用い、それ以外の縮小映像は、縮小映像信号を使用する。 FIG. 10 shows an example when stopping at the “9th floor”. “L9” is an enlarged video signal of the “9th floor” and is installed on the elevator hall of the “8th floor” that has already passed. “S8”, which is a reduced image of the camera, and “S10” and “S14”, which are reduced images of the surveillance cameras installed on the elevator floors of the “10th floor” and “14th floor”, which are not scheduled to stop. The video signal is used, and the other reduced video uses the reduced video signal.
　このように、映像配列部１０７は、エレベーター制御部１３から送信されるエレベーターの停止階情報、及び次に停止する階の情報に従って、縮小映像信号、縮小・拡大映像信号、及び縮小加工映像信号を並び替えて、表示映像信号として、メモリ１０１に書き込む。
　そして、映像出力部１０８は、映像配列部１０７がメモリ１０１に書き込んだ表示映像信号を読み出して、モニター１４に送信するための信号を出力し、モニター１４で、表示を行う。 In this way, the video array unit 107 outputs the reduced video signal, the reduced / enlarged video signal, and the reduced processed video signal according to the elevator stop floor information transmitted from the elevator control unit 13 and the next floor information to be stopped. Rearranged and written in the memory 101 as a display video signal.
The video output unit 108 reads the display video signal written in the memory 101 by the video array unit 107, outputs a signal for transmission to the monitor 14, and displays on the monitor 14.
　このように構成することで、エレベーターの動きに合わせて、次に停止する階のエレベーター乗場の状況を、拡大表示して、エレベーターの乗客に知らせることができ、また、エレベーターが停止しない予定の階のエレベーター乗場の映像を加工して見え難くすることで、停止する予定のエレベーター乗場の映像を、エレベーターの乗客に分かりやすく伝えることができる。 By configuring in this way, the elevator landing status of the next floor to be stopped can be enlarged and notified to the elevator passengers in accordance with the movement of the elevator, and the elevator floor where the elevator will not stop It is possible to convey the image of the elevator hall that is scheduled to stop to the elevator passengers in an easy-to-understand manner by processing the image of the elevator hall in order to make it difficult to see.
　実施の形態２．
　実施の形態１では、映像配列部１０７は、縮小映像については、停止しない予定の階については、映像加工部１０６で加工された縮小加工映像信号を用いて表示するように構成したが、本実施の形態２では、次以降に停止する階の縮小映像を、停止する順に並べるように構成する。 Embodiment 2. FIG.
In the first embodiment, the video arrangement unit 107 is configured to display the reduced video for the floor that is not to be stopped using the reduced video signal processed by the video processing unit 106. In the second form, the reduced videos of the floors that stop after the next are arranged in the order of stop.
　図１１は、１５階建てビルで、エレベーターが、次に“３階”に停止する予定で、その後、“４階”、“６階”、“８階”、“９階”、“１１階”、“１２階”、“１３階”、及び“１５階”に停止する予定の場合の表示例を示したものであり、停止しない予定の階については、縮小映像を表示しない。
　この図１１では、表示できる縮小映像に限りがあるため、“１５階”が表示されていないが、エレベーターが運行されるに従って表示される。例えば、エレベーターが“４階”に到着するときには、図１２に示すように、“１５階”の縮小映像が表示されることになる。 FIG. 11 shows a 15-story building where the elevator is scheduled to stop at “3rd floor”, then “4th floor”, “6th floor”, “8th floor”, “9th floor”, “11th floor” “,“ 12th floor ”,“ 13th floor ”, and“ 15th floor ”are shown as examples of display, and a reduced video is not displayed for floors that are not to be stopped.
In FIG. 11, since the reduced video that can be displayed is limited, “15th floor” is not displayed, but is displayed as the elevator is operated. For example, when the elevator arrives at the “4th floor”, a reduced image of the “15th floor” is displayed as shown in FIG.
　さらに、エレベーターの運行が進んで、“６階”に到着する前には、図１３のように、“１５階”に停止してから、エレベーターが続けて運行（最上階に到着した場合は、その後下降方向に、最下階に到着した時は、その後上昇方向に運行）した時に、停止する可能性が有る順番で、かつ現在停止しない予定の階の縮小加工映像信号を表示する。本実施の形態では、“１４階”が相当し、図１３のように、“１４階”の縮小加工映像信号を表す　“Ｓ１４”のグレー色（斜線部）表示となる。 Furthermore, before the elevator operation progresses and arrives at “6th floor”, as shown in FIG. 13, after stopping at “15th floor”, the elevator continues to operate (if it arrives at the top floor, After that, when arriving at the lowest floor in the descending direction, the reduced processing video signal of the floor that is not scheduled to stop at the present time is displayed in the order in which there is a possibility of stopping when it travels in the ascending direction thereafter. In the present embodiment, “14th floor” corresponds, and as shown in FIG. 13, “S14” gray color (hatched portion) representing the reduced processed video signal of “14th floor” is displayed.
　このように、映像配列部１０７は、エレベーターが運行して、停止する順番に縮小映像信号を配列し、エレベーターが、停止する予定の階が無く、配列する縮小映像信号が、無くなった場合は、現在停止しない予定の階であって、かつエレベーターが運行していて、停止する可能性が有る順に、縮小加工映像信号を配列するように構成してもよい。 In this way, the video arrangement unit 107 arranges the reduced video signals in the order in which the elevator operates and stops, and when the elevator has no floor scheduled to stop and the reduced video signals to be arranged disappear, The reduced processed video signals may be arranged in the order of the floors that are not scheduled to be stopped and the elevators are in operation and may stop.
　このように構成することで、エレベーターの乗客に、停止する予定の階のエレベーター乗場の状況を分かりやすく伝えることができ、降車時の安全性を向上することができる。
　また、縮小映像信号、縮小・拡大映像信号、又は縮小加工映像信号の表示に、それぞれ対応する階の階床情報を、“１Ｆ”又は“２Ｆ”のように表示してもよい。図１４は、図１３に、階床情報を追加した表示例である。縮小・拡大映像信号を表示している階は、“６階”であるため、“６Ｆ”と表示する（図１４の４０１）。また、縮小映像信号及び縮小加工映像信号についても、階床情報を、例えば、“８Ｆ”などのように表示する（図１４の４０２）。 By comprising in this way, the condition of the elevator boarding of the floor to be stopped can be easily communicated to the passengers of the elevator, and the safety when getting off can be improved.
Further, floor information corresponding to the floor corresponding to the display of the reduced video signal, the reduced / enlarged video signal, or the reduced processed video signal may be displayed as “1F” or “2F”. FIG. 14 is a display example in which floor information is added to FIG. Since the floor displaying the reduced / enlarged video signal is “sixth floor”, “6F” is displayed (401 in FIG. 14). For the reduced video signal and the reduced processed video signal, the floor information is displayed as, for example, “8F” (402 in FIG. 14).
　このように表示することで、エレベーターの乗客は、それぞれ降車する階の状況を分かりやすく確認することができる。 By displaying in this way, the passengers of the elevator can easily check the situation of the floor where they get off.
　実施の形態３．
　高層ビル等、エレベーター階床が多い場合で、監視レコーダー１１の解像度がフルハイビジョンの４倍の４Ｋ（３８４０ドット×２１６０ドット等）、８倍の８Ｋ（７６８０ドット×４３２０ドット等）となった場合、監視レコーダー１１からの映像に含まれる分割映像の数は、２５又は３６等に増やすことが可能になる。 Embodiment 3 FIG.
