Description

Surveillance system, surveillance image receiving apparatus, and surveillance image receiving program

The present invention relates to a monitoring system that distributes a monitoring image captured by a monitoring camera or the like, and in particular, monitoring data such as image data and audio data from a camera in monitoring an intruding object or fixed point observation at a remote place or multiple points. And a monitoring image receiving device that receives, displays, and stores monitoring data.

2. Description of the Related Art Conventionally, there is a network-compatible monitoring system that monitors a suspicious person or the like by receiving an image captured by a monitoring camera via a network and displaying it on a display in a monitoring computer.

As one of the functions of image monitoring technology by a monitoring image distribution device (hereinafter also referred to as “Web encoder” as appropriate) that encodes and distributes a video captured by a monitoring camera in such a network-compatible monitoring system, a monitoring computer There is a superimposed display function for displaying device information and the like in addition to the actually captured video. With the superimposed display function, it is possible to display the device name registered in the Web encoder, information on the shooting time, and the like. Further, when displaying the monitoring video on the monitoring computer, display software for PC (personal computer) (hereinafter referred to as “viewer software”) is used. In the superimposed display, after the received video data is decoded by the viewer software, device information and the like are drawn on the video. When browsing the monitoring video on the monitoring computer, the video in a state where the processing up to the superimposed display is completed is displayed.

Also, items that are displayed in a superimposed manner include information that is included in the viewer software and information that includes warning messages necessary for monitoring the Web encoder. As a method for the viewer software to acquire such information of the Web encoder, the viewer software transmits an information request command to the Web encoder to request information, or the Web encoder is voluntarily sent to the transmission destination registered therein.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the same parts as those in the other drawings are denoted by the same reference numerals.

(First embodiment)
(Overview of monitoring system)
FIG. 1 is a diagram illustrating an overall configuration of a monitoring system according to the present embodiment. The monitoring system according to the present embodiment will be described on the assumption that it is a network-compatible monitoring system. However, the present embodiment is not limited to this, and other image distribution systems having a function of distributing images can also be used. Applicable.

In the monitoring system shown in FIG. 1, a Web camera 100a, a Web camera 100b, and a Web encoder 100c, which are monitoring image distribution apparatuses, are connected to a PC 200a and a PC 200b, which are monitoring image reception apparatuses, via a network 10. . The web camera 100 a and the web camera 100 b are surveillance cameras in which a web encoder and a camera are integrated, and have a function of encoding captured images and distributing them to the network 10. The Web encoder 100 c is connected to the camera 101 and has a function of encoding an image captured by the camera 101 and distributing it to the network 10. That is, monitoring data such as monitoring images and audio is distributed from the Web camera 100a, the Web camera 100b, and the Web encoder 100c to the PC 200a and the PC 200b via the network 10.

Monitoring data such as monitoring images and sound distributed from the Web camera 100a, Web camera 100b, and Web encoder 100c is received by the PC 200a and PC 200b via the network 10. The monitoring data is displayed and output on the displays of the

PCs

200a and 200b, the NTSC (National Television System Committee) monitor, and the like. The PC 200a and the PC 200b are monitoring terminal devices for monitoring an image captured by the Web camera 100a or the like. In FIG. 1, there are a plurality of monitoring image distribution apparatuses (Web camera 100a, Web camera 100b, Web encoder 100c), but there may be only one monitoring image distribution apparatus.

(Motion detection processing)
In the present embodiment, as an example, a case will be described in which moving object detection is performed on a monitoring image in the Web camera 100a and the result is transmitted to the PC 200a and the PC 200b. First, as shown in FIG. 15, generally, a moving object detection area 91 that is a target of moving object detection is set in advance among the segments (64 segments in FIG. 15) divided in the monitoring image. When the moving object is detected in the moving object detection area 91 (when a video change occurs), the number of the segment in which the video change occurs in the moving object detection area 91 together with the monitoring image data 90 (21 in this example, 22, 29, 30, 35, 43) are notified to the PC 200a ′ and the PC 200b ′. In the PC 200a ′ and the PC 200b ′, the

segments

21, 22, 29, 30, 35, and 43 are recognized as detection segments whose video has changed. Further, since the range of the moving object detection area 91 is determined by the Web camera 100a ′ on the transmission side, the numbers of the detection segments recognized by the PC 200a ′ and PC 200b ′ that are the reception side devices are the same. Further, when the range of the moving object detection area 91 is changed, the detection segments recognized by the PC 200a ′ and the PC 200b ′ change in the same manner.

On the other hand, in the monitoring system according to the present embodiment, as shown in FIG. 2, in the Web camera 100a, all segments are set as moving object detection areas. When a video change is detected, all of the segment numbers where the video change has occurred together with the monitoring image data 20 (21, 22, 28, 29, 30, 35, 36, 37, 43 in this example). Is notified to the PC 200a and the PC 200b. In the PC 200a and the PC 200b,

target areas

21 and 22 to be monitored for moving object detection in each device are set in advance. Then, among the segments of the video change occurrence notified from the Web camera 100a, the segments included in the

target areas

21 and 22 are recognized as detection segments. For example, since the target area 21 is the segments 20 to 24 and 28 to 32 in the PC 200a, the

segments

21, 22, 28, 29, and 30 are recognized as detection segments. In the PC 200b, since the target area is the

segments

3, 4, 11, 12, 19, 20, 27, 28, 35, 36, 43, 44, 51, 52, 59, 60, the

segments

28, 35, 36 , 43 are recognized as detection segments.

(Configuration of monitoring system)

The monitoring image distribution apparatus 100 includes an image holding unit 110 and a transmission unit 120. The monitoring image receiving apparatus 200 includes a receiving unit 210, an additional display setting information holding unit 220, a processing unit 230, and an additional display setting information changing unit 240. Here, the monitoring image distribution apparatus 100 is the Web camera 100a, the Web camera 100b, and the Web encoder 100c in FIG. The monitoring image receiving apparatus 200 is the PC 200a or PC 200b in FIG.

Note that the monitoring image distribution device 100 and the monitoring image receiving device 200 described below are general memory such as a CPU (Central Processing Unit) and a RAM (Random Access Memory) (not shown), a storage device such as a hard disk, and a network interface. This is realized by a configuration similar to that of a simple computer. The function of each component of the monitoring image distribution device 100 and the monitoring image reception device 200 is, for example, when the CPU of each device reads and executes a program stored in a hard disk or the like, or, for example, an FPGA (Field This function is realized by custom design of sequencer logic in Programmable Gate Array. Each data such as monitoring image data, monitoring image related information, and additional display setting information described below is data stored in the storage device of each device, and includes image holding unit 110 and additional display setting information holding. The unit 220 is a data storage area provided in the storage device of each device.

(Configuration of Monitoring Image Distribution Device 100)
(Image holding unit 110)
The image holding unit 110 has a function of holding monitoring image data of a monitoring image captured by the imaging device. Here, the “imaging device” specifically corresponds to a surveillance camera or the like, but the imaging device may be integrated with the surveillance image distribution device 100 or may be a separate body. For example, the web cameras 100a and 100b in FIG. 1 are obtained by integrating the monitoring image distribution device 100 and the imaging device. Further, for example, the camera 101 and the Web encoder 100c in FIG. 1 are configured such that the monitoring image distribution device 100 and the imaging device are separate. In addition, when the monitoring image distribution device 100 and the imaging device are separate, such as the camera 101 and the Web encoder 100c, the image holding unit 110 is connected from the imaging device (camera 101) via a communication interface, for example. The monitoring image is received and held in a storage device such as a hard disk inside the monitoring image distribution device 100 (Web encoder 100c).

(Transmitter 120)
The transmission unit 120 transmits monitoring image related information, which is information related to the monitoring image and is defined by the imaging device or the monitoring image distribution device 100, in association with the monitoring image data of the monitoring image. In this embodiment, the monitoring image related information is information indicating the result of moving object detection in the monitoring image in the monitoring image distribution apparatus 100, and is information indicating a segment in which a video change has occurred in the monitoring image. As described above, the monitoring image related information may be information representing the state of the imaging device such as the imaging direction, zoom, and focus in the imaging device.

(Specific example of monitoring image related information)
FIG. 4 is a diagram illustrating a specific example of the monitoring image related information. Note that the monitoring image related information shown in FIG. 4 is in accordance with the example shown in FIG. 2, and as a result of the moving object detection in the monitoring image distribution device 100, the segment of the video where the video change has occurred in the monitoring image data 20 is detected.

Numbers

21, 22, 28, 29, 30, 35, 36, 37 and 43 are shown. The monitoring image related information shown in FIG. 4 is composed of 64 bits, and each bit represents whether or not a video change has occurred in 64 segments in the monitoring image data 20. When the bit is “1”, it means that the segment is a segment where a video change has occurred, and when the bit is “0”, it means that no video change has occurred in that segment. That is, in this example, the bit representing the motion detection result of the

segments

21, 22, 28, 29, 30, 35, 36, 37, and 43 is “1”, and thus “0x00 0x00 0x0C 0x1C 0x38”. The monitoring image related information of “0x20 0x00 0x00” is generated in the monitoring image distribution device 100 and transmitted to the monitoring image receiving device 200.

Further, the transmission unit 120 associates the monitoring image data of the monitoring image and the monitoring image related information and transmits them to the monitoring image receiving apparatus 200. Specifically, for example, the monitoring image related information is embedded in the monitoring image data. Sent. FIG. 5 is a diagram illustrating a configuration example of monitoring image data. Further, the monitoring image data shown in FIG. 5 is JPEG (Joint Photographic Experts Group) stream data. The related information is stored in the User Data area 30 of the header of JPEG stream data, for example.

It should be noted that this example is merely an example, and it is only necessary that the monitoring image data of the monitoring image and the monitoring image related information are associated with each other, and may be transmitted at different timings. For example, when transmitting the monitoring image data and the monitoring image related information in the transmission unit 120, if the same identification information is attached to both, the monitoring image receiving apparatus 200 that receives them transmits the monitoring image data and the monitoring image related information. Can be determined by the identification information that both are associated with each other.

Further, the transmission unit 120 may generate monitoring image related information triggered by the occurrence of a predetermined event, and transmit the monitoring image related information in association with the monitoring image data of the monitoring image. . Specifically, for example, it is a case where monitoring image related information representing the result of moving object detection is transmitted from the monitoring image distribution device 100 to the monitoring image reception device 200, triggered by the detection of a video change in the monitoring image. . That is, when these events occur, monitoring image related information as shown in FIG. 4 is generated and stored in a storage device such as a RAM of the monitoring image distribution device 100. Then, the transmission unit 120 reads the monitoring image data and the monitoring image related information from the storage device of the monitoring image distribution device 100, and sends the monitoring image data and the monitoring image related information to the network 10 via the communication interface.

(Configuration of monitoring image receiving apparatus 200)
(Receiver 210)
The receiving unit 210 receives monitoring image data and monitoring image related information transmitted from the transmission unit 120 of the monitoring image distribution apparatus 100. Here, the receiving unit 210 may receive the monitoring image data and the monitoring image related information at the same time, or may receive them separately. That is, the receiving unit 210 may receive monitoring image data in which monitoring image related information as shown in FIG. 5 is embedded, or the monitoring image related information and the monitoring image received at different timings. Data with the same identification information attached may be recognized as being associated. More specifically, the receiving unit 210 stores monitoring image data and monitoring image related information received via, for example, a communication interface in a storage device such as a hard disk or a RAM.

(Additional display setting information holding unit 220)
The additional display setting information holding unit 220 determines additional information related to the monitoring image to be displayed and output together with the monitoring image composed of the monitoring image data received by the receiving unit 210 according to the content of the monitoring image related information. It holds additional display setting information that is information and information specified by the monitoring image receiving apparatus 200. The additional display setting holding unit 220 is information for determining an application to be executed together with the display output of the monitoring image according to the contents of the monitoring image related information instead of the additional display setting information. You may have the additional process setting information holding part which hold | maintains the additional process setting information which is the information prescribed | regulated with the apparatus 200. FIG.
For example, when the monitoring image related information received by the receiving unit 210 is information indicating the result of moving object detection, the additional information is displayed together with the monitoring image on the display of the monitoring image receiving apparatus 200 according to the result of moving object detection. Corresponding warning message etc. For example, when the monitoring image related information received by the receiving unit 210 is information indicating the result of moving object detection, the application is an application for sounding an alarm or warning notification.

(Processing unit 230)
Based on the monitoring image related information and the additional display setting information, the processing unit 230 determines whether or not to display additional information together with the display output of the monitoring image. Determine the content of additional information to be displayed. In the present embodiment, the additional display setting information determines at least one of a character string and an image to be superimposed on the monitoring image (hereinafter referred to as “character string etc.” as appropriate) according to the content of the monitoring image related information. The processing unit 230 determines whether or not to superimpose at least one of the character string and the image on the monitoring image and outputs the display, and when the display is output, the content of at least one of the character string and the image To decide.
Further, as described above, when the monitoring image receiving apparatus includes the additional processing setting information holding unit, the processing unit 230 displays the monitoring image based on the monitoring image related information and the additional processing setting information. Whether or not to execute the application is determined together with the output, and when executing the application, the contents of the application to be executed may be determined.

(Specific example of additional display setting information)
FIG. 6 is a diagram illustrating a specific example of additional display setting information. In the monitoring image receiving device 200, which area of the moving object detection result represented by the monitoring image related information transmitted from the monitoring image distribution device 100 is the target of moving object detection in the own device (that is, in FIG. 2). As information indicating the target areas 21 and 22), additional display setting information as shown in FIG. 6 is held. That is, in FIG. 6, the additional display setting information is information that defines an area in the monitoring image that is a detection target of the moving object detection in the monitoring image receiving apparatus 200.

Further, when there are a plurality of monitoring image receiving apparatuses 200, the additional display setting information held in each monitoring image receiving apparatus 200 may be different. In this example, FIG. 6A shows additional display setting information held in the PC 200a in FIG. 2, and FIG. 6B shows additional display setting information held in the PC 200b in FIG. In the additional display setting information, similarly to the monitoring image related information shown in FIG. 4, the range of the

target areas

21 and 22 is indicated by 1 and 0 of each bit. Of the 64 segments, a segment having a bit of “1” represents a segment to be detected, and a segment having a bit of “0” represents a segment not to be detected. For example, FIG. 6A shows that segments with segment numbers 20 to 24 and 28 to 32 are to be detected.

In the

target areas

21 and 22 indicated by the additional display setting information, whether or not there is a segment whose bit is “1” in the monitoring image related information, that is, a segment in which a video change has occurred is determined by the processing unit. Determined at 230. When there is a segment in which a video change has occurred, at least one of a preset character string and image is superimposed on the received monitoring image and displayed. As a result, the PC 200a and the PC 200b can recognize whether or not there has been a video change within the

target areas

21 and 22 defined by the additional display setting information in the device itself.

In this way, in the monitoring image receiving apparatus 200, since the target area to be detected for moving object detection can be set uniquely, unlike the conventional moving object detection method as shown in FIG. Different moving object detection can be performed for each device 200. For example, with respect to one monitoring image capturing an entrance / exit of a building passage, the PC 200a can detect the passage of the passage, and the PC 200b can detect an intruder passing through the entrance / exit.

(Other specific examples of additional display setting information)
FIG. 7 is a diagram showing another specific example of the additional display setting information. In the additional display setting information of FIG. 7, “conditional expression” indicates a condition regarding the contents of the monitoring image related information. Also, “correct” is “1” (correct) and “0” (error). “1” indicates that the processing set in the column is executed when the conditional expression is satisfied in the monitoring image related information, and “0” indicates that the conditional expression is not satisfied in the monitoring image related information. Indicates that the processing set in the column is executed.

For example, in the condition of the first line of the additional display setting information shown in FIG. 7, when the first bit of the monitoring image related information is “1”, the coordinates of the monitoring image received by the receiving unit 210 ( 30 and 5) indicates that the character string with the character string ID “1” is superimposed and displayed. Further, the monitoring image receiving apparatus 200 also holds the information shown in FIG. 8A in a storage device such as a hard disk of its own apparatus. The information shown in FIG. 8 indicates the character size, color, and content of the character string for each “ID” of the character string. FIG. 8B shows a display example of character strings with IDs “1” to “5”. For example, the character string of ID “1” means that the character string is “warning!” With the character color “0xFFFFFF” at 10 points. That is, the processing unit 230 compares the additional display setting information as shown in FIG. 7 with the monitoring image related information received by the receiving unit 210, and then is designated by the “address” of the additional display setting information. With reference to the information in FIG. 8 for the character string ID to be displayed, the designated character string is superimposed on the monitoring image and displayed.

It should be noted that whether or not to be a target for moving object detection in the monitoring image receiving apparatus 200 is determined based on the additional display setting information that is a bit string as shown in FIG. 6, and the additional display setting information including the conditional expression as shown in FIG. The process such as the superimposed display executed by may be determined.

In FIG. 8B, for the convenience of drawing, shades of color are expressed by shading. For example, “Warning!” And “Area 1” may be displayed in white, “Warning!” In red, “* Caution” in yellow, and “Shooting location XXX” in green.

Returning to FIG. 7, the condition on the second line indicates that when the conditional expression is satisfied in the monitoring image related information, the image indicated by “address” is superimposed and displayed. In the condition of the third row, the “conditional expression” means that the first bit or the second bit of the monitoring image related information is “1”, but “correct” is “0”. Therefore, when the first or second bit of the monitoring image related information is not “1”, that is, when both the first bit and the second bit are “0”, the character string with the character string ID “2” is superimposed. It means to display. The condition on the fourth line means that the execution file represented by “address” is executed when the monitoring image is displayed and output.

As described above, since the additional display setting information can be uniquely set in the monitoring image receiving device 200, the monitoring image reception is performed even if the same monitoring image related information is distributed to the plurality of monitoring image receiving devices 200. The apparatus 200 can vary the conditions for superimposing the character string and the like, and can also vary the character string and the image to be superimposed on the monitoring image. For example, the information that the user wants to know may differ depending on whether the user monitoring the monitoring image with the monitoring image receiving apparatus 200 is a security guard or a system administrator. Therefore, it is more convenient than a conventional network-compatible monitoring system. Is expensive. Further, the monitoring image receiving apparatus 200 sets a character string or the like to be superimposed on the monitoring image in consideration of the language used by the user who uses the monitoring image (that is, sets a display language such as a character string to be superimposed on the monitoring image). It is also possible.

3, the additional display setting information changing unit 240 has a function of changing the additional display setting information held in the additional display setting information holding unit 220. Specifically, the additional display setting information changing unit 240 receives an input from the user of the monitoring image receiving device 200 via a user interface such as a keyboard and a mouse, and stores a hard disk or the like according to the input content. The additional display setting information held in the device is rewritten. Thereby, when there are a plurality of monitoring image receiving devices 200, additional display setting information can be reset for each monitoring image receiving device 200.

(Details of configuration of monitoring image receiving apparatus 200)
FIG. 9 is a diagram illustrating a more specific configuration example of the monitoring image receiving apparatus 200. The receiving unit 210 includes, for example, a monitoring image data receiving unit 211, a monitoring image data acquisition unit 212, and a monitoring image related information acquisition unit 213. That is, the monitoring image data reception unit 211 receives the monitoring image data and the monitoring image related information transmitted from the monitoring image distribution device 100, and the monitoring image data acquisition unit 212 and the monitoring image related information acquisition unit 213 respectively monitor the monitoring image. Data and monitoring image related information are acquired. The monitoring image data acquired by the monitoring image data acquisition unit 212 is decoded by the monitoring image data decoding unit 231.

Further, the monitoring image related information determination unit 232 reads the additional display setting information from the additional display setting information holding unit 220 provided in the storage device 15 such as a hard disk and acquires it by the monitoring image related information acquisition unit 213. The contents of the monitored image related information are determined. In accordance with this determination result, the information (superimposed display item) shown in FIG. 8 is read from the superimposed display item storage unit 261 provided in the storage device 15. Then, the superimposition display unit 233 performs processing for superimposing and displaying the read superimposition display item on the monitoring image data decoded by the monitoring image data decoding unit 231, and the video output unit 234 displays and outputs it. Is done.

(Comparison with conventional network monitoring system)
Here, the configuration of the monitoring system according to the present embodiment is compared with the configuration of a conventional network-compatible monitoring system such as Patent Document 1. FIG. 16 is a diagram illustrating a configuration example of a monitoring image receiving device in a conventional monitoring system. In a conventional monitoring image receiving apparatus, monitoring image data on which a character string or the like is superimposed is distributed from a monitoring image distribution apparatus (not shown), and the monitoring image data receiving unit 901 of the monitoring image receiving apparatus receives this monitoring image data. . Then, only the monitoring image data is acquired by the monitoring image data acquisition unit 902, and the monitoring image data is decoded by the monitoring image data decoding unit 903. The superimposed display information acquisition unit 904 acquires superimposed display information such as a character string superimposed on the monitoring image data received by the monitoring image data receiving unit 901. In addition, the superimposition display unit 905 performs processing for superimposing and displaying the acquired superimposition display information (character string or the like) on the decoded monitoring image data, and the video output unit 906 displays and outputs it.

That is, in the conventional monitoring image receiving apparatus shown in FIG. 16, a character string or the like superimposed on the monitoring image data received by the monitoring image data receiving unit 901 is superimposed and displayed and output. In the monitoring image receiving apparatus 200 of the present embodiment shown in FIG. 9, the monitoring image related information is acquired by the monitoring image related information acquisition unit 213, and the superimposed display item corresponding to the monitoring image related information is read from the memory or the like. Is superimposed and displayed. Therefore, when there are a plurality of monitoring image receiving devices 200 in the network-compatible monitoring system, different superimposed display items are read based on the additional display setting information stored in each monitoring image receiving device 200. Since they are superimposed on the monitoring image, even if the same monitoring image data is distributed from the monitoring image distribution device 100, different character strings and the like are superimposed and displayed on each monitoring image receiving device 200.

In addition, in the conventional network-compatible monitoring system, in addition to the monitoring image data of the monitoring image, data such as a character string to be superimposed on the monitoring image is transmitted from the monitoring image distribution device to the monitoring image receiving device, so that it is superimposed and displayed. There was a limit to the amount of data such as character strings. Further, there is a problem that an excessive load is applied to the network 10 depending on the amount of data such as character strings. According to the monitoring system according to the present embodiment, since the monitoring image related information is composed of a 64-bit bit string, the amount of data transmitted to the network 10 can be suppressed. Moreover, since the data amount of the monitoring image related information embedded in the monitoring image data can be small, the free area can be used for other purposes.

In the configuration of FIG. 9, the monitoring image data receiving unit 211, the monitoring image data acquiring unit 212, and the monitoring image related information acquiring unit 213 correspond to the receiving unit 210 in FIG. Also, the monitoring image data decoding unit 231, the monitoring image related information determination unit 232, the superimposition display unit 233, and the video output unit 234 correspond to the processing unit 230 in FIG.

(Processing flow of the monitoring system)
10A and 10B are flowcharts showing the flow of processing in the monitoring system according to this embodiment. FIG. 10A is a processing flowchart of the monitoring image distribution apparatus 100, and FIG. 10B is a processing flowchart of the monitoring image reception apparatus 200.

First, the flowchart of FIG. 10A will be described. A monitoring image is acquired from an imaging device such as a camera provided in the monitoring image distribution device 100 (step S101), monitoring image data to be distributed to the monitoring image reception device 200 is created, and the image holding unit 110 It is held (step S102).

When a motion detection (video change) event occurs in this monitoring image (step S103), the monitoring image related information in the header portion of the monitoring image data is changed (step S104). In addition, the area | region where the monitoring image relevant information in the header part of monitoring image data is stored should just be empty data in the meaning that there is no monitoring image relevant information by default. Then, in the transmission unit 120, the monitoring image data is distributed (step S105). The above process is repeated until the process is completed (step S106).

Next, the flowchart of FIG. 10B will be described. In the monitoring image receiving apparatus 200, the additional display setting information held in advance in the additional display setting information holding unit 220 is read onto the memory (step S201). In addition, the superimposed display items in FIGS. 7 and 8A are read onto the memory (step S202).

When the monitoring image data distributed in step S105 of FIG. 10A is received by the receiving unit 210 (step S203), the monitoring image data is decoded and an output video for display output is created (step S204). . Also, monitoring image related information is acquired from the header portion of the monitoring image data received in step S203 (step S205).

Next, in the processing unit 230, the monitoring image related information acquired in step S205 is compared with the conditional expression of the additional display setting information read in step S201 (step S206). If the corresponding event has occurred in the monitoring image (when the condition is met) (step S207), a character string or the like is superimposed on the output video created in step S204 (step S208). Then, the output video on which the character string or the like is superimposed in step S208 is output to a display device such as a display (step S209).

In addition, when the corresponding event has not occurred in the monitoring image (when it does not meet the conditional expression) (step S207), the monitoring image is output as it is to the display or the like (step S209).

The above processing is repeated until it is finished (step S210).

Note that the processing in steps S201 and S202 may be executed after the processing in step S203 and before the processing in S206.

(Second Embodiment)
FIG. 11 is a diagram showing another embodiment. In the monitoring system shown in FIG. 11, the Web encoder 100d (monitoring) connected to the pan head integrated camera 102, which is a camera capable of controlling the direction of the camera from a separate client device (PC200c) (not shown). An image distribution device 100) is connected to a PC 200c (monitoring image reception device 200) via a network 10. In addition, in the pan / tilt head integrated camera 102, the camera orientation, zoom, focus, and other states can be preset and registered. Thereafter, when the preset button is pressed on the client device, the camera direction, zoom, focus, and the like of the camera platform integrated camera 102 are changed to a preset preset state.

In the present embodiment, when the camera orientation or the like is changed in the camera platform integrated camera 102 in this way, setting values such as the camera orientation, zoom, and focus at that time are generated as monitoring image related information by the Web encoder 100d. Is done. Then, this monitoring image related information is embedded in the monitoring image data of the monitoring image and distributed from the Web encoder 100d to the PC 200c.

Further, in the PC 200c, additional display setting information that defines character strings to be superimposed and displayed in correspondence with the direction of the camera and the like is stored. For example, if the direction of the camera platform integrated camera 102 indicated in the monitoring image related information indicates the direction of Area 1, the character string “Area 1” (FIG. 11A) is used, and the camera platform integrated camera 102 In the case where the direction of “Area2” indicates the direction of Area2, the character string “Area2” (FIG. 11B) is set in the additional display setting information so as to be superimposed on the monitoring image. When the monitoring image data in which the monitoring image related information is stored is received by the PC 200c, the received monitoring image related information is compared with the additional display setting information stored in the own device, and the monitoring image is stored. Depending on the orientation of the camera indicated by the related information, the character string “Area1” or “Area2” is superimposed on the monitoring image and displayed.

For example, the pan / tilt head integrated camera 102 is a fixed camera installed at a predetermined location, and the position of the angle is known in advance by the angle of the camera. Based on this, in the PC 200c, for each angle of the camera, for example, character strings such as “main gate” and “entrance door” are preset in the additional display setting information so as to be superimposed on the monitoring image.

In FIG. 11, only the PC 200c is shown as the monitoring image receiving device 200, but a plurality of monitoring image receiving devices 200 may exist. Similar to the first embodiment, when there are a plurality of monitoring image receiving devices 200, different character strings or the like are superimposed on each monitoring image receiving device 200 according to the direction of the pan-head camera 102 or the like. Can be displayed.

It should be noted that not only when the camera orientation of the camera platform integrated camera 102 is changed from the client device, but also when the camera orientation of the camera platform integrated camera 102 is changed by a user's manual operation or a control signal from the Web encoder 100d. In this case, the monitoring image related information may be transmitted together with the monitoring image. In addition, when the direction of the camera of the pan head integrated camera 102 changes with time, or when the direction of the camera of the pan head integrated camera 102 changes in response to the reaction of an external sensor, The direction of the camera platform integrated camera 102 and the like may be distributed to the monitoring image receiving apparatus 200 as monitoring image related information together with the monitoring image.

(Third embodiment)
By the way, as a monitoring image receiving apparatus 200 described above, a network type video decoding apparatus (conventional apparatus for receiving a monitoring image distributed over a network from a monitoring image distribution apparatus such as a Web camera or a Web encoder and outputting it to a monitor or the like) (Hereinafter referred to as “Web decoder”). This Web decoder has a function of decoding encoded image data distributed from a network monitoring image distribution device such as a Web camera or Web encoder, and converting it into a signal format that can be output to an analog monitor or the like.
As one of the functions of the Web decoder, there is a function of superimposing and displaying information such as a character string on the output video. Examples of information to be superimposed and displayed include the name of the video distribution source device, but the conventional Web decoder has the following problems.

The various settings of the Web decoder are changed from the setting Web page provided on the network from the Web decoder. Further, it is necessary to access the setting Web page from a network browser of a personal computer (PC) connected on the same network as the Web decoder. In other words, each time the character string superimposed display function on the output video is turned ON / OFF, it is necessary to access and change the Web page for setting the Web decoder from the PC.

In addition, while the Web camera and Web encoder are installed at a position distant from the video viewer of the monitoring image, the Web decoder is installed and used near the video viewer to output a live video to the monitor. . Therefore, during normal operation after the basic setting for the Web decoder is completed, a control controller or the like is connected to the Web decoder, and direct operation is performed without using a PC or the like.

That is, when control such as superimposed display is performed by the Web decoder, there are the following problems in handling.
As described above, since the Web decoder is used by being connected to an analog monitor or the like, it is often installed in the vicinity of the video monitor and is an environment in which the video monitor can easily operate the actual machine directly. However, even in that case, in order to switch the display / non-display of the superimposed character string displayed on the screen, it is necessary to access the Web page for setting the Web decoder and change the display setting. was. For this reason, a PC for changing the setting had to be prepared separately.

The monitoring system according to the present embodiment described below can cope with such a problem.

(Configuration of monitoring system)
FIG. 12 is a diagram illustrating the overall configuration of the monitoring system according to the present embodiment. In the configuration shown in FIG. 12, the functions of the Web cameras 100a and 100b, the camera 101, and the Web encoder 100c are as described in the first embodiment. Instead of these, the pan head integrated camera 102 and the Web encoder 100d (FIG. 11) described in the second embodiment may be used.

Further, the Web decoder 200d shown in FIG. 12 receives video from the Web encoder 100c and the Web cameras 100a and 100b via the network 10 and outputs them to the monitor 310. The Web decoder 200d has a function of superimposing information such as a name and time on the received monitoring image data and outputting the same.

In addition to the control from the PC 400, the Web decoder 200d can also directly control from the control controller 320 connected to the Web decoder main body. From the controller 320 for control, it is possible to control switching of images output to the monitor 310, operation control of a camera having a turning function, and the like via the Web decoder 200d. Note that the Web decoder 200d corresponds to the monitoring image receiving apparatus 200 of FIG. 3, and the basic functions are as described in the first embodiment.

That is, since the Web decoder 200d is a video output device, it is possible to superimpose a character string or the like on the output video as in the case of the viewer software in the client PC. As for the display method and display items of the character string, the display method using the monitoring image related information and the additional display setting information can be used as it is, as in the first and second embodiments. Further, as described in the first and second embodiments, not only superimposed display but also activation of a predetermined application is possible. (Hereinafter, these functions are collectively referred to as “superimposed display” as appropriate.)

Note that a client device such as a client PC (hereinafter referred to as “PC”) 400 exists on the network 10. From these client devices, various setting changes and control of each client device such as the Web encoder 100c, the Web cameras 100a and 100b, and the Web decoder 200d can be performed.

As described above, conventionally, the setting change of the Web decoder is performed by accessing the setting change Web page of the Web decoder from a terminal device such as a PC. However, in a network system that operates a Web decoder, there is not always a terminal device that can access the Web decoder, and there are cases where the setting cannot be changed immediately.

Also, since the Web decoder is connected to the monitor by a cable, it is often installed at a position relatively close to the user. In that case, it is often easier to operate a switch or the like provided in the Web decoder than to change the setting by connecting to the Web decoder via a network. Therefore, in the present embodiment, a changeover switch for setting whether to perform superimposed display or the like on the Web decoder is provided. Hereinafter, the configuration of the Web decoder 200d will be described in detail.

(Configuration of Web decoder 200d)
FIG. 13 is a diagram illustrating a configuration example of the Web decoder 200d according to the present embodiment. The Web decoder 200d of the present embodiment is characterized in that a superimposing display changeover switch 302 is provided. Further, the Web decoder 200d corresponds to the monitoring image receiving apparatus 200 in FIG. 3 and functions other than the superimposing display switching switch 302 are the same as the functions in the monitoring image receiving apparatus 200. That is, the monitoring image data receiving unit 211 corresponds to the receiving unit 210 of FIG. 3, and the monitoring image data processing unit 303 is the additional display setting information holding unit 220, the processing unit 230, and the additional display setting information changing unit of FIG. 240 and further includes a video signal output unit 304.
The configuration of the video output device 310 is the same as the configuration of the conventional video output device.

The Web decoder 200d receives the monitoring image data of the monitoring image transmitted from each monitoring image distribution device (Web camera 100a, 100b, Web encoder 100c in FIG. 12) on the network in the monitoring image data receiving unit 211. Thereafter, the monitoring image data processing unit 303 decodes the monitoring image data and the like, and the display signal is output from the video signal output unit 304 to the monitor 310 by NTSC output or the like.

Furthermore, in the Web decoder 200d of this embodiment, the state of the overlay display etc. switch 302 attached to the main body of the Web decoder 200d is read. If the overlay display etc. switch 302 is ON, the monitor image data processing unit 303 outputs it. Perform superimposing display on the video. The output video 311 is an example when the camera name is superimposed and displayed as an example.
When the superimposing display switching switch 302 is OFF, the monitoring image data processing unit 303 outputs only the monitoring video without executing the processing for superimposing display or the like (output video 312).

In order to realize the function in the Web decoder 200d, the Web decoder 200d stores and holds two types of setting information, such as control settings such as superimposed display and ON / OFF settings such as superimposed display, in a memory such as a RAM. .
The superimposing display control setting is a function for switching selection of whether priority is given to switch control by the superimposing display switching switch 302 or control based on a setting from a conventional setting Web page (hereinafter referred to as “network control”). Have The ON / OFF setting such as the superimposed display holds the setting from the conventional setting Web page.

The setting Web page of the Web decoder 200d can be changed from the setting Web page by providing setting items for setting these setting information.
That is, when the superimposing display switching switch 302 of the Web decoder 200d main body is OFF, the superimposing display on the distribution video or the like depending on the ON / OFF setting state such as the superimposing display preset in the setting Web page. Can be switched on / off.

This makes it possible to switch ON / OFF of the superimposed display on the distribution video even in a situation where the superimposed display switching switch 302 of the Web decoder 200d in a remote location cannot be directly changed. Note that control settings such as superimposed display can be changed only from the setting Web page, and a switch for switching between switch control priority and network control priority is not attached to the main body of the decoder 200d.

(Processing flow of the monitoring system)
FIG. 14 is a flowchart showing the flow of processing in the monitoring system according to the present embodiment.

The control software executed in the monitoring image data processing unit 303 of the Web decoder 200d first refers to a control setting such as superimposed display (step S301).
In a state where the control setting for superimposing display etc. is set to switch control priority (step S302), ON / OFF of superimposing display etc. on the distribution video can be switched by the superimposing display switching switch 302 of the main body of the Web decoder 200d. To. That is, referring to the state of the superimposing display switch 302 (step S303), if the superimposing switch 302 is ON (step S304), superimposing display is performed on the output video (step S305). ).

In addition, when the control setting such as superimposition display is set to the network control priority (step S302), the ON / OFF setting such as superimposition display is referred to (step S306). When the ON / OFF setting such as the superimposed display is ON (step S307), the superimposed display is performed on the output video (step S305).
Finally, the video signal output unit 304 outputs a display video (step S308).

The group of setting items described above need only have a function for ensuring setting switching by network control as well as the state of the changeover switch 302 such as the superimposed display of the Web decoder 200d main body. It doesn't have to be the same. For example, the superimposing display control setting and the superimposing display ON / OFF setting are combined into one, and “switch control priority”, “ON” (equivalent to “network control priority” + “superimposition display ON” in the above), “ The setting information having three values “OFF” (equivalent to “network control priority” + “superimposition display OFF” in the above) and the superimposing display switching switch 302 of the main body of the Web decoder 200d may be switched. .

Further, the ON / OFF setting of the superimposing display switching switch 302 may be input from an external control controller 320 as shown in FIG.
The Web decoder 200d also has a function of dividing the display screen on the monitor 310 and outputting videos from a plurality of image distribution sources as one video. Therefore, a plurality of superimposing display switching switches may be provided in the main body of the decoder 200d so that ON / OFF of superimposing display or the like can be switched for each image distribution source.

As described above, in the monitoring system according to the present embodiment, by attaching a switch for superimposing display or the like to the Web decoder 200d, ON / OFF for superimposing display on the output video without using the setting change PC. Can be switched. Conventionally, a procedure for accessing a Web page for setting the Web decoder from a PC using a network browser and changing the display / non-display setting of the superimposed display function has been required. Since the decoder 200d can be changed only by switching a switch provided in the main body, the setting procedure is simplified. In addition, since it is not necessary to permanently install a PC for changing settings near the video monitor, it is possible to reduce the cost and space of the system.

(Other embodiments)
When the detection signal is output from an external sensor such as an infrared sensor that detects the entry / exit of a person or a sensor that detects opening / closing of a door, the value of the detection signal is used as monitoring image related information, and the monitoring image distribution device 100 May be distributed together with the monitoring image.

In the above embodiment, the case where a character string or the like is superimposed and displayed on the monitoring image in the monitoring image receiving apparatus 200 has been described. However, other processing may be performed. For example, a warning sound or sound may be output together with the display output of the monitoring image, or a warning lamp provided in the monitoring image receiving device 200 may blink. Moreover, the monitoring image may be recorded automatically. Furthermore, these processes may be used in combination.

(Monitoring image reception program)
In the monitoring system described above, it is necessary to install a monitoring image receiving program in the computer that is the monitoring image receiving apparatus 200. This monitoring image receiving program is the following program. That is, the monitoring image data of the monitoring image captured by the imaging device, and the monitoring image related information that is information related to the monitoring image associated with the monitoring image and defined by the imaging device, Information for determining additional information related to the monitoring image to be displayed and output together with the monitoring image in accordance with the first step received from the imaging device and the content of the monitoring image related information, which is defined by the computer Based on the second step of reading additional display setting information, which is information, from the storage device of the computer, the monitoring image related information, and the additional display setting information, the additional output together with the display output of the monitoring image Determining whether to display the additional information, and determining the content of the additional information to be displayed when the additional information is displayed. A step, a monitoring image reception program for execution.

That is, each step shown in the flowchart of FIG. 10B can be executed by storing the monitoring image receiving program in a storage device included in the computer, and reading and executing the program by the CPU. .

The monitoring image receiving program may be installed and executed on a computer by being downloaded through a network, or may be installed and executed on a computer by being stored and distributed in a storage medium. .

In addition, the scope of the present invention is not limited to the illustrated and described exemplary embodiments, and includes all embodiments that provide the same effects as those intended by the present invention. Further, the scope of the invention can be defined by any desired combination of particular features among all the disclosed features.
