(Explanation of the action)

Next, the operation will be described with reference to FIG. 1.

(Operation of the Encoding Device 100)

The camera 140 installed in the car outputs the captured analog image signal 2 to the A / D converter 101 of the encoding apparatus 100 (S01). Moreover, the elevator control apparatus 130 outputs "elevator information 3" to the encoder 103 of the encoding apparatus 100 (S02). Here, "elevator information 3" is a digital signal which shows the real-time driving situation of an elevator, for example,

(1) information indicating the location of the car,

(2) information indicating a moving direction of the car;

(3) information indicating failure of the elevator,

(4) information indicating the door opening and closing of the car,

And the like. It is possible to freely set what information (signal) the "elevator information 3" includes, but in the following description, "(1) information indicating a car position" to "(4) door opening and closing of the car are shown. It is assumed that four pieces of "information" are included.

(Processing in Encoder 100)

The real time analog image signal 2 (real time image) in the real time car is input to the A / D converter 101 (S01), and converted into the digital image signal 4. The converted digital image signal 4 is input to the frame buffer 102 and temporarily stored (S03). The encoder 103 executes the encoding process of the digital image signal 4 stored in the frame buffer 102 and the encoding process of the elevator information 3, and the "image encoding bit string 5 including the elevator information 3". (An example of coded bit string data) is generated and output to the decoding device 110 (S04).

(When encoder 103 conforms to JPEG)

The encoder 103 (encoder) is, for example, an encoder based on JPEG. In the case of conforming to JPEG, the encoder 103 performs encoding processing according to JPEG, so as to first "image code bit stream 5" from the digital image signal 4 stored in the frame buffer 102 (elevator information Before the bit string of (3) is inserted).

3 is a diagram showing an image encoding bit string 5 produced by the encoder 103 based on JPEG. As shown in Fig. 3, the image coded bit string 5 generated based on the JPEG starts from the start marker 601, continues to the segment 602, the image data 603, and the end marker 604. Ends in) Here, the image data 603 is a bit string obtained by digitally compressing the digital image signal 4 representing the image in the car captured by the camera 140. In the area of the image data 603, for example, one frame of the image in the car is inserted (recorded).

In addition, the comment segment area 6020 is included in the segment 602. The comment segment area 6020 is an area which can be used independently by the user. The comment segment area 6020 is composed of a COM marker 6021, a segment length 6022 of the comment segment area (the number of bytes of code added to the comment segment + 2), and a comment segment 6023.

(Encoding Table 1031)

In addition, as shown in FIG. 4, the encoder 103 includes an encoding table 1031 (an example of predetermined elevator information encoding) for encoding the elevator information 3. The encoder 103 performs encoding process of the elevator information 3 using the encoding table 1031. That is, the encoder 103 uses the encoding table 1031,

(1) car location information,

(2) direction of movement,

(3) failure information of the elevator,

(4) door opening and closing information

Is encoded, and the encoded bit strings are inserted in this order into the comment segment 6023 of the created image coded bit string 5, and " image coded bit string 5 including elevator information 3 ". "Is generated. In this case, the elevator information 3 inserted as the bit string corresponds to the bit string of the image inserted in the area of the image data 603. That is, the elevator information 3 inserted in the comment segment 6023 is the elevator information 3 at the point in time at which the image of the image data 603 was captured (the same time as the image or the latest time). As shown in Fig. 3, the segment 602 (area containing the bit string of elevator information) and the image data 603 (area containing the bit string of the digital image signal) are continuous. The image of the inside and the elevator information at the time of photographing this image can be related.

The "association" of the image in the car and the elevator information at the time of photographing the image can be defined by the syntax of JPEG or MPEG4. In the first embodiment, as an example of association, as described above, a continuous segment 602 (area containing bit strings of elevator information) and image data 603 (area containing bit strings of digital image signals) are related. It is built, but continuous is an example, and other associations are possible based on the syntax of JPEG or MPEG4.

(Example of insertion into comment segment in JPEG)

A specific example is shown below. As the elevator information 3, it is assumed that the following coded bit strings are input.

(1) Car location information: the lowest floor of the building

(2) Moving direction of car: UP

(3) Failure information of the elevator: failure factor 1 and failure factor 3

(4) Opening and closing information of car door: door closed

In the above case, the encoding bit string is obtained using the encoding table 1031 shown in FIG. 4, as follows.

(1) Car location information: "0000 0000" (00 in hexadecimal)

(2) Moving direction: 「0000 0000」 (00 in hexadecimal)

(3) Breakdown information of elevator: 「0000 0101」 (05 in hexadecimal notation)

(4) Door opening and closing information: "1111 1111" (FF in hexadecimal notation).

Therefore, (1) to (4) can be expressed as "0000 05FF" in hexadecimal notation.

Since the coded bit string of the COM marker 6021 is "FFFE" (as defined in JPEG), the elevator information 3 added to the comment segment area 6020 in this case is the comment segment area 6020 of FIG. )

The encoder 103 transmits the "picture encoding bit string 5 containing the elevator information 3" to the decoding device 110 in the manager's room of a building via a LAN (Looal Area Network) or the like.

(Process by Decoding Device 110)

The decoding device 110 receives the "image coded bit string 5 including the elevator information 3" from the encoding device 100 and stores it in the storage unit 112 (S05). The decoder 111 reads and decodes the "image coded bit string 5 including the elevator information 3" stored in the storage unit 112 (S06). In this case, the decoder 111 outputs the decoded image 7 and elevator information 8 (information after decoding of the elevator information 3) to the monitor 120 as a result of the decoding process. When the encoder 12 conforms to JPEG, the decoder 111 decodes the bit string of the image according to the criterion (an example of "image decoding rule corresponding to a predetermined image coding rule") based on JPEG.

(Decoding of elevator information (3))

In this case, the decoder 111 generates the decoded image 7 by performing a decoding process according to the regulation of JPEG, for example. The decoder 111 also has a decoding table 1111 (an example of an elevator information decoding rule corresponding to a predetermined elevator information encoding rule) similar to the encoding table 1031 shown in FIG. 4. The decoder 111 refers to the decoding table 1111 and encodes the elevator information 3 included in the comment segment 6023 among the "image coded bit strings 5 including the elevator information 3". The decoding process of the bit string is executed to output the elevator information 8 (elevator information after decoding) to the monitor 120. In other words, the decoder 111, in the case of decoding processing of the coded bit string of the elevator information 3,

(1) car location information,

(2) direction of movement,

(3) failure information of the elevator,

(4) door opening and closing information

In the following order, decoding is performed using the decoding table 1111 of FIG.

(Operation of the monitor)

The decoded image 7 and elevator information 8 are output from the decoding device 110 to the monitor 120. 5 shows an example of a screen displayed by the monitor 120. As shown in FIG. 5, the screen of the monitor 120 is displayed separately without overlaying the decoded image 7 and the elevator information 8. In FIG. 5, the display 201 shows a layer, and the figure 202 shows a layer.

(1) Car Location Information: 1st Floor

(2) Moving direction: UP

(3) door closed

Three of them are shown.

In addition, the display 203 indicates that "failure factor 1" and "failure factor 3" are occurring as failure information. Moreover, the image 204 has shown the video in the car inside the present car. By such a display, the inside video of the car is not obscured by the display of the elevator information (operation status of the elevator), and it becomes easy to see. The decoder 111 only decodes the "image coded bit string 5 including the elevator information 3" and decodes without requiring dedicated means for associating image data with elevator information. The elevator information 8 linked to the image 7 and the decoded image 7 can be obtained easily. In this manner, the decoded image 7 and the elevator information 8 linked thereto can be easily displayed with a simple configuration.

(When encoder 103 conforms to MPEG4)

In addition, the encoder 103 may be based on MPEG4, for example. FIG. 7 shows the "image encoding bit string 5" created when the encoder 103 performs encoding processing according to the MPEG4 specification (an example of a predetermined image encoding rule). In the "picture coded bit stream 5" of FIG. 7, the (n-1) th image data 401 and the (n) th image data 402 are shown. The (n-1) th image data 401 is an image captured first. For example, the (n) th image data 402 is an example of an area including header information 801 (an example of an area including a bit string of elevator information) and an image data 802 (a bit string of a digital image signal). It consists of). The header information 801 and the image data 802 are contiguous areas. In the area of the image data 802, for example, one frame of the image in the car is inserted (recorded). Alternatively, a plurality of frames may be recorded in the area of the image data 802. The number of frames inserted in the area of the image data 802 is implementation dependent. As in the case of JPEG, the encoder 103 has an encoding table 1031 (an example of an elevator information encoding rule) shown in FIG. The encoder 103 performs encoding processing of the input elevator information 3 by using the encoding table 1031. The encoder 103 is located in the area of the user data 8202 in the user data area 8020 existing in the image encoding bit string 5 (FIG. 7) which has already been created.

(1) car location information,

(2) direction of movement,

(3) failure information of the elevator,

(4) door opening and closing information

In this order, each encoded coded bit string is inserted to create an "image coded bit string 5 including the elevator information 3". In this case, the coded bit string of the elevator information 3 inserted in the area of the user data 8802 corresponds to the bit string of the image inserted in the area of the image data 802. In other words, the elevator information 3 inserted into the user data 8802 is the elevator information 3 at the time point at which the image of the image data 802 was captured (the same time as the shooting or the latest time). Similarly, the elevator information 3 inserted in the header information 701 is the elevator information 3 at the point in time at which the image of the image data 702 was captured (at the same time as the shooting or at the latest time).

FIG. 8 shows a specific example of "image coded bit string 5 including elevator information 3" in the user data area 8020. As shown in FIG. The user data area 8020 is included in the header information 801 and is an area that can be used independently by the user. The user data area 8020 is configured to add user data 8802 after the user data start code 8201. As elevator information 3,

(1) car location information: the lowest floor of the building,

(2) direction of movement: UP,

(3) failure information of the elevator: failure factor 1 and failure factor 3,

(4) door opening and closing information: the door closing is entered,

Assume that In this case, since the coded bit string of the user data start code is "000001 B2" (defined in MPEG4), in this case, the user data area 8020 becomes a signal shown in FIG.

(Association of image information and elevator information)

9 is a conceptual diagram for explaining the generation of the "image coded bit string 5 including the elevator information 3" by the encoder 103 in the sense of reconfirmation. The camera 140 continuously outputs to the A / D converter 101 an analog image signal 2 which is a current video signal (real time image) photographing the inside of the car. The A / D converter 101 sequentially converts the analog image signal 2 that is continuously output to the digital image signal 4 and outputs it to the encoder 103. On the other hand, the elevator control device 130 continuously outputs the current elevator information 3 as a digital signal to the encoder 103. The elevator information 3 is the information (the information which shows the real-time driving situation) which shows the current driving condition of an elevator. In FIG. 9, the information of the direction of an arrow is input to the encoder 103 first. As shown in FIG. 9, the analog image signal 2 is converted into a digital image signal 4 and input to the encoder 103. The encoder 103 converts the digital image signal 4, which is continuously input, into the image encoding bit string 5, and bits the elevator information 3 in a predetermined region of the image encoding bit string 5. Insert deteriorated information. 9 (n-1) 401 and (n) 402 indicate portions of the image data 401 and the digital image signal 4 and elevator information 3 encoded as the image data 402 of FIG. 7. In other words, in (n-1) 401, the digital image signal 4 and the elevator information 3 are bit degraded at substantially the same angle. The same applies to (n-1) 401 for (n) 402, which becomes an image in the next car. That is, in the elevator information 3 and the analog image signal 2, current real-time information is continuously input to the encoding apparatus 100. The conversion from the analog image signal 2 to the digital image signal 4 is instantaneous. Therefore, the encoder 103 bit-deteriorates the digital image signal 4 and the elevator information 3 at the timing shown in FIG. 9, so that a point in time (time) at which the image in the car was taken without requiring a special device. And the elevator information (that is, the operation status of the elevator) can be associated at that time.

(Decoder in MPEG4)

In this case, the decoder 111 of the decoding device 110 conforms to MPEG4. In other words, the decoder 111 decodes the image coding bit string according to the regulation ("an example of the image decoding rule corresponding to a predetermined image coding rule") in accordance with MPEG4. In addition, the decoder 111 uses the decoding table 1111 (an example of an elevator information decoding rule corresponding to a predetermined elevator information coding rule) as the encoded bit string of the elevator information 3 in the same manner as in the case of JPEG. Decrypt In this way, the decoder 111 decodes the image defined in MPEG4 and, in addition to the output of the decoded image 7, uses the encoding table 1031 to encode the image including the elevator information 3. Bit string 5 ”to decode the coded bit string of the elevator information 3 included in the user data 8802, and output the elevator information 8 to the monitor 120. FIG. The operation of the monitor 120 is the same as in the case of JPEG.

(Past image reproduction)

With reference to FIG. 10, the case where the decoding device 110 reproduces the past image is demonstrated. In the case of Fig. 10, use of MPEG4 is assumed. In FIG. 10, the encoding device 100 includes a clock unit 104 and the decoding unit 110 includes a data extraction unit 113 with respect to FIG. 1.

(Encoding device 100)

The clock unit 104 has a clock function for measuring the current date and time. The clock unit 104 outputs date and time information, which is a digital signal representing the current date and time, to the encoder 103. For example, the clock part 104 outputs "2007.11.17, 14:32:56" as date and time information (it shows November 17, 2007, 14:32:56 second). When the encoder 103 inputs the date and time information from the clock unit 104, the encoder 103 inserts the date and time information when generating the "picture coded bit string 5 including the elevator information 3" described above. For example, in the case of MPEG4, the encoder 103 inserts temporal information into header information such as the header information 701 and the header information 801 shown in FIG. For this reason, the image data inserted into the image data 702 corresponds to the date and time information inserted into the header information 701, and the image data recorded in the image data 802 corresponds to the date and time information recorded in the header information 801. Corresponds. The encoder 103 outputs the "picture encoding bit string 5 containing the elevator information 3" (hereinafter, sometimes referred to as the temporal information attached bit string) to which the temporal information is inserted, to the decoding device 110. .

(Decoding device 110)

In the decoding device 110, the storage unit 112 stores the temporary information-bearing bit string output from the encoder 103. In this case, when a date and time is input to the data extracting unit 113, the data extracting unit 113 extracts a date and time information bit string corresponding to the input date and time from the storing unit 112 with the input date and time as a key. Output to decoder 111. When the decoder 111 inputs the temporal information-based bit string, the decoder 111 decodes the "image coded bit string 5 including the elevator information 3" into which the temporal information is inserted and monitors 120. ).

11 shows a case where the informational bit string is displayed on the monitor 120 when it is decoded. As shown in FIG. 11, on the screen of the monitor 120, the date and time 205 at which the image 204 was captured are displayed as "2007.11.17, 14:32". For this reason, it is possible to simply search for and display the elevator information at the time when the image in the car and the image in the car were photographed at a past time and displayed on the monitor 120.

As described above, in the elevator monitoring apparatus 1000, the encoder 103 generates the "image coded bit string 5 including the elevator information 3", so that the monitor is not overlaid on the elevator information and the image in the car. 120 may be displayed.

In the elevator monitoring apparatus 1000, the encoder 103 generates the "image encoding bit string 5 including the elevator information 3" by associating the bit string of the digital image signal with the bit string of the elevator information. No means for associating elevator information is necessary.

In the elevator monitoring apparatus 1000, since the decoder 111 decodes the "image coded bit string 5 including the elevator information 3" and displays it on the monitor 120, the elevator information and the image in the car are overlaid. Can display without work.

In the elevator monitoring apparatus 1000, since the encoder 103 and the decoder 111 comply with any one of JPEG and MPEG4 rules, the device can be realized with a simple configuration by using the existing rules.

In the elevator monitoring apparatus 1000, the encoder 103 encodes the elevator information using the encoding table 1031. Therefore, the elevator table can be set flexibly with the encoding table 1031.

In the elevator monitoring apparatus 1000, the elevator information 3 includes at least one of information indicating the position of the car, information indicating the moving direction of the car, information indicating the failure of the elevator, and information indicating opening and closing of the door of the car. Contains information. Therefore, such information important for elevator monitoring can be displayed on the monitor 120 without overlaying the image in the car.

As described above, in the elevator monitoring device, the camera 140 is provided in the car, and the image of the camera 140 is displayed while the driving state of the elevator is displayed.

After digitizing the image picked up by the camera 140, when encoding the digitized image data using image compression technology, encoding information (elevator information) obtained from the elevator control panel is also used. An encoding device 100 for outputting an encoding bit string including image data;

A decoding device for simultaneously decoding image data and elevator information from the coded bit stream;

The elevator monitoring apparatus provided with the display which displays the decoded image and elevator information which are the decoding results was demonstrated.

By the above structure,

(1) By inserting a coded bit string of elevator information into an area defined by an image compression technique and not affecting the image quality of a decoded image, the elevator information is displayed at the time when image data and image data are captured. It was to be related. For this reason, it is no longer necessary to overlay elevator information on the decoded image displayed on the display. The building manager can therefore check the entire situation in the car.

(2) By decoding one coded bit string, elevator information can be obtained at the same time as the image data and the image data are captured. For this reason, the dedicated means required for associating image data with elevator information has become unnecessary. For this reason, the information of an elevator can be displayed with a simple structure easily at the time when image data and the image data were image | photographed.
