The storage unit 12 may temporarily store encoded moving image data in a format that can be displayed on, for example, a display unit. The storage unit 12 may store the information on the status of the elevator 1 for a long period of time, for example, as an operation history. The storage unit 12 may store data of moving images captured by the in-car camera 7 for a long period of time. The storage unit 12 may store information on the status of the elevator 1 and video data captured by the in-car camera 7 as monitoring information in association with each other according to the time when the information or data was acquired.

The output section 13 is a section that outputs data of an image to be displayed to the display section. The output unit 13 is connected to the hall display unit 2 and the in-car display unit 6 .

The control unit 14 is a part that controls the operation of the image data processing device 5 . The operation of the image data processing device 5 controlled by the control unit 14 includes, for example, outputting image data to the display unit, switching data to be output to the display unit, and the like. The control unit 14 operates based on switchable operation modes. Operation modes include, for example, normal mode, first distribution mode, and second distribution mode. During normal operation, the operation mode of the control unit 14 is set to, for example, the normal mode. The normal mode is an operation mode for seamlessly displaying an image on the display unit. Here, the seamless image display is, for example, continuous display of a plurality of images such as moving images or still images with no temporal intervals that are noticeable to the user. In the normal mode, the control unit 14 causes the display unit to display an image based on, for example, a preset schedule. The first distribution mode is an operation mode in which moving images captured by the in-car camera 7 are distributed to the outside of the image data processing device 5 while seamlessly displaying images on the display unit. The first delivery mode is an example of a delivery mode. The second distribution mode is an operation mode in which moving images captured by the in-car camera 7 are distributed to the outside of the image data processing device 5 regardless of the display on the display unit.

The elevator 1 is connected via a network 15 to equipment such as a server computer provided in the distribution center 16 and equipment such as a server computer provided in the monitoring center 17 . The distribution center 16 is a base for distributing content such as moving images or still images. The monitoring center 17 is a base for collecting and monitoring information on the status of the elevator 1 . The monitoring center 17 collects information on the status of the elevator 1 from the elevator control device 4 or the like via the communication unit 9 of the image data processing device 5, for example.

For example, when receiving a distribution start request from the monitoring center 17, the control unit 14 distributes the moving image captured by the in-car camera 7 to the monitoring center 17 as follows. The control unit 14 causes one of the decoders 10a and 10b to decode the data output from the in-car camera 7. FIG. The control unit 14 causes the encoder 11 to re-encode the decoded data so as to convert the data into a format that can be distributed over the network 15 . The control unit 14 distributes the data encoded again by the encoder 11 to the monitoring center 17 through the communication unit 9 and the network 15 . The control unit 14 stops distribution of moving images to the monitoring center 17 when receiving a distribution stop request from the monitoring center 17, for example.

Here, one of the decoders 10a and 10b that decodes the data output from the in-car camera 7 is an example of the first decoder. Of the decoders 10a and 10b, the one that does not decode the data output by the in-car camera 7 is an example of a second decoder. The control unit 14 may operate either the decoder 10a or the decoder 10b as the first decoder. The control unit 14 may switch which one of the decoders 10a and 10b to operate as the first decoder according to the operation status of each.

Some or all of the functions of the communication unit 9, the decoder 10a, the decoder 10b, the encoder 11, the storage unit 12, the output unit 13, and the control unit 14 of the image data processing device 5 are installed in the image data processing device 5, for example. It is executed based on the program etc.

Next, with reference to FIG. 2, an example of display on the display section in normal mode will be described.
FIG. 2 is a diagram showing an example of a schedule in the image data processing device 5 according to the first embodiment.

In the normal mode, the control unit 14 causes the display unit such as the hall display unit 2 or the in-car display unit 6 to display an image based on the schedule stored in the storage unit 12, for example. The schedule includes, for example, the display order of the content displayed on the display unit, the file corresponding to the content, and the display time of the content. Here, the content includes, for example, moving image content or still image content. The content includes content representing the operation status of the elevator 1, advertisement content, bulletin content, and the like.

In the example shown in FIG. 2, the moving image A having display order 1 is first displayed for 30 seconds. The moving image A is distributed from the distribution center 16, for example. At this time, the data of the moving image A is decoded by the decoder 10a, for example, and displayed on the display unit.

After the moving image A is displayed, the moving image B of display order 2 is displayed for 30 seconds. The moving image B is distributed from the distribution center 16, for example. Data for Movie B requires decoding prior to display. Here, if the decoding process of the data of the moving picture B is started after the display of the moving picture A is completed, there is a time interval between the moving picture A and the moving picture B while the decoding process of the data of the moving picture B is being performed. put away. Therefore, while the moving image A to be decoded is being displayed on the decoder 10a, the control unit 14 simultaneously decodes the moving image B on the decoder 10b. The control unit 14 may temporarily store the data of the decoded moving image B in the storage unit 12 . Since the decoding process of the moving image B is performed in advance in this way, the control unit 14 can seamlessly switch between a plurality of moving images and display them on the display unit.

After the moving image B is displayed, the moving image C of display order 3 is displayed. Movie C is displayed until the movie content ends. The decoding processing of the data of the moving image C is performed in the decoder 10a in parallel while the moving image B to be decoded is displayed on the decoder 10b, for example.

After the moving image C is displayed, the still image P of display order 4 is displayed for 5 seconds. The still picture P does not require decoding processing that requires a long processing time.

After the still image P is displayed, the moving image D with display order 5 is displayed. Movie D is displayed until the movie content ends. The decoding process of the data of the moving image D is performed in the decoder 10b while the still image P is being displayed, for example. When the decoding process cannot be performed sufficiently while the still picture P is being displayed, for example, the decoding process of the data of the moving picture D is performed in parallel while the moving picture C to be decoded is displayed on the decoder 10a. It may be done in the decoder 10b.

After the moving image D is displayed, the moving image E with display order 6 is displayed for 30 seconds. The decoding processing of the data of the moving image E is performed in the decoder 10a in parallel while the moving image D decoded by the decoder 10b is being displayed, for example. In cases such as when sufficient decoding processing cannot be performed while the moving image D is being displayed, the decoding processing of the data of the moving image E may be performed in the decoder 10a while the still image P is being displayed, for example.

Similarly, after the moving image E is displayed, the moving image F with display order 7 is displayed for 30 seconds. In this example, after the movie F is displayed, the movie A with display order 1 is again displayed for 30 seconds.

Note that the control unit 14 may cause the display unit to display content such as moving images or still images not set in the schedule based on an interrupt signal or the like from the outside. The control unit 14 may cause the decoder 10a or the decoder 10b, which does not decode data of the displayed moving image, to decode the content to be interrupted.

The control unit 14 may display the moving image captured by the in-car camera 7 on the display unit. At this time, the control unit 14 may cause one of the decoders 10a and 10b, which does not decode data of the displayed moving image, to decode the moving image captured by the camera.

The display order and display time of the schedule can be changed as parameters by the operation of the building manager, for example. Schedules may be switched based on time of day, day of the week, or the like.

Next, an example of the operation of the image data processing device 5 will be described with reference to FIG.
FIG. 3 is a flow chart showing an example of the operation of the image data processing device 5 according to the first embodiment.

In step S<b>01 , the control unit 14 performs display based on a preset schedule as operations in the normal mode. After that, the operation of the image data processing device 5 proceeds to step S02.

In step S02, the control unit 14 determines whether or not a distribution start request has been received from the monitoring center 17 or the like. When the determination result is No, the operation of the image data processing device 5 proceeds to step S01. When the determination result is Yes, the operation of the image data processing device 5 proceeds to step S03.

In step S03, the control unit 14 determines whether it has received a control signal from the elevator control device 4, for example. Here, the control signal is a signal output when the elevator control device 4 determines that a user is in the vicinity of a display unit such as the hall display unit 2 or the in-car display unit 6 . The elevator control device 4 determines that the user is near the display section based on the detection result of the user detection section 8, for example. Alternatively, the elevator control device 4 may determine that the user is near the display section such as the hall or the car 3 when detecting the operation of the user who registers the call. Alternatively, the elevator control device 4 may determine that the user is near the display section based on the operation status of the elevator 1 . If the determination result as to whether the control signal has been received is Yes, the operation of the image data processing device 5 proceeds to step S04. If the determination result as to whether the control signal has been received is No, the operation of the image data processing device 5 proceeds to step S09.

In step S04, the control unit 14 switches the operation mode to the first distribution mode. After that, the operation of the image data processing device 5 proceeds to step S05.

In step S<b>05 , the control unit 14 converts the moving image captured by the in-car camera 7 into a data format that can be distributed over the network 15 by either one of the decoders 10 a and 10 b and the encoder 11 . In this example, a decoder 10a is used to convert the moving images captured by the in-car camera 7. FIG. After that, the operation of the image data processing device 5 proceeds to step S06.

In step S<b>06 , the control unit 14 displays one of the displays of the first distribution mode illustrated below. At this time, the decoder 10a is not used except for conversion for distribution. The control unit 14 causes the display unit to display the image regardless of the decoder 10a used for distribution. The control unit 14 may display a combination of displays in the first distribution mode illustrated below.

For example, the control unit 14 causes the display unit to display only still images whose data is stored in the storage unit 12 as the operation in the first distribution mode. At this time, the control unit 14 continues to display, for example, only one still image. Alternatively, the control unit 14 may seamlessly switch and display a plurality of still images. Since the control unit 14 displays only still images that do not require decoding processing that takes a long time, the display unit can perform seamless display without using the decoder 10a in addition to conversion for distribution.

Alternatively, the control unit 14 causes the display unit to display a still image between a plurality of moving images as the operation of the first distribution mode. For example, the control unit 14 causes the display unit to display the moving image decoded by the decoder 10b. After that, the control unit 14 causes the display unit to display, for example, a still image whose data is stored in the storage unit 12 . At this time, the control unit 14 may seamlessly switch and display a plurality of still images. During this time, the control unit 14 causes the decoder 10b to decode the moving image to be displayed next. After that, the control unit 14 seamlessly switches the display of the display unit from the still image to the moving image of the decoded data. For example, when two moving images are displayed continuously in a set schedule, the control unit 14 may insert a still image display between the two moving images. In this way, the control unit 14 uses only the decoder 10b for decoding the moving image to be displayed. The control unit 14 displays a still image that does not require a long-time decoding process while the moving image is being decoded. Thereby, the control unit 14 can cause the display unit to perform seamless display without using the decoder 10a in addition to conversion for distribution.

Alternatively, the control unit 14 causes the display unit to display the moving image captured by the in-car camera 7 for which the decoding process has already been performed by the decoder 10a as the operation of the first distribution mode. Since the control unit 14 displays only moving images that do not require additional decoding processing, the display unit can perform seamless display without using the decoder 10a in addition to conversion for distribution.

Alternatively, as the operation of the first distribution mode, the control unit 14 causes the display unit to display the moving image captured by the in-car camera 7, for which the decoder 10a has already performed the decoding process, between the plurality of moving images. For example, the control unit 14 causes the display unit to display the moving image decoded by the decoder 10b. After that, the control unit 14 seamlessly switches the moving image captured by the in-car camera 7, which has already been decoded by the decoder 10a, and displays it on the display unit. During this time, the control unit 14 causes the decoder 10b to decode the moving image to be displayed next. After that, the control unit 14 seamlessly switches the display of the display unit from the moving image captured by the in-car camera 7, which has already been decoded by the decoder 10a, to the moving image of the data decoded by the decoder 10b. For example, when two moving images are displayed consecutively in a set schedule, the control unit 14 may insert the display of the moving image captured by the in-car camera 7 between the two moving images. . Thereby, the control unit 14 can cause the display unit to perform seamless display without using the decoder 10a in addition to conversion for distribution.

After step S06, the operation of the image data processing device 5 proceeds to step S07.

In step S07, the control unit 14 determines whether or not a distribution stop request has been received from the monitoring center 17, for example. When the determination result is No, the operation of the image data processing device 5 proceeds to step S05. When the determination result is Yes, the operation of the image data processing device 5 proceeds to step S08.

In step S08, the control unit 14 switches the operation mode to the normal mode. After that, the operation of the image data processing device 5 proceeds to step S01.

In step S09, the control unit 14 switches the operation mode to the second distribution mode. After that, the operation of the image data processing device 5 proceeds to step S10.

In step S<b>10 , the control unit 14 converts the moving image captured by the in-car camera 7 into a data format that can be distributed via the network 15 by either one of the decoders 10 a and 10 b and the encoder 11 . In this example, a decoder 10a is used to convert the moving images captured by the in-car camera 7. FIG. Here, since the elevator control device 4 determines that there is no user near the display unit such as the hall display unit 2 or the in-car display unit 6 in the second distribution mode, the control unit 14 seamlessly display is not necessary. Therefore, the control unit 14 may stop the display on the display unit. After that, the operation of the image data processing device 5 proceeds to step S11.

In step S11, the control unit 14 determines whether or not a distribution stop request has been received from, for example, the monitoring center 17 or the like. If the determination result is No, the operation of the image data processing device 5 proceeds to step S10. When the determination result is Yes, the operation of the image data processing device 5 proceeds to step S08.

As described above, the image data processing device 5 according to Embodiment 1 includes the encoder 11, the first decoder, the second decoder, the storage section 12, and the control section . The encoder 11 encodes moving image data. The first decoder decodes the encoded video data. The second decoder decodes the encoded video data. The first decoder and the second decoder operate in parallel with each other. The storage unit 12 stores data of one or more still images. The control unit 14 operates by switching between operation modes including the normal mode and the first distribution mode. Here, the display unit displays an image represented by the input data. The in-car camera 7 is provided in the car 3 of the elevator 1. - 特許庁The in-car camera 7 outputs the captured video as encoded data. In the normal mode, the control unit 14 causes the display unit to display the moving image of the data decoded by one of the first decoder and the second decoder. During this time, the control unit 14 causes the other of the first decoder and the second decoder to decode the data of the moving image to be displayed next. Thereby, the control unit 14 continuously displays a plurality of moving images. In the first distribution mode, the control unit 14 causes the first decoder to decode the data of the moving image captured by the in-car camera 7, and then causes the encoder 11 to encode the data, thereby converting the data into distributable data. In the first distribution mode, the control unit 14 causes the display unit to display at least one of the one or more still images whose data is stored in the storage unit 12 .

In the normal mode, the control unit 14 can seamlessly switch the display of images including moving images by causing two decoders to perform decoding processing in parallel. Also, in the first distribution process, one of the decoder 10a and the decoder 10b is used to distribute moving images. Even if two decoders cannot be secured in this manner, the control unit 14 causes the display unit to perform display without using one of the decoders in addition to conversion for distribution. As a result, even when the moving image captured by the in-car camera 7 is distributed in real time, the control unit 14 can cause the display unit to perform seamless display. Thus, the image data processing device 5 can seamlessly display images. Since the display on the display unit is not interrupted, the image data processing device 5 can make the user less anxious. Also, the reproduction quality of the displayed content is enhanced. Therefore, the customer satisfaction of the user is enhanced. In addition, since no additional decoder is required in addition to the two decoders 10a and 10b that are normally used, the image data processing device 5 realizes real-time distribution of moving images in the car 3 and seamless display of contents. Compatible with minimal configuration.

Also, the control unit 14 switches the operation mode to the first distribution mode when a control signal is input from the elevator control device 4 . The elevator control device 4 is a device that controls the operation of the elevator 1 .
Further, the control unit 14 switches the operation mode to the first distribution mode when the user of the elevator 1 is detected.

When a user of elevator 1 is detected, or when a user is near a display such as hall display 2 or in-car display 6, there is a high need for seamless display on the display. Since the operation mode of the control unit 14 is switched to the first distribution mode at this time, the seamless presentation of the information to the user can be performed more reliably.

Note that the image data processing device 5 may superimpose other information on the moving image captured by the in-car camera 7 and display it on the display unit. The information to be superimposed may be character information, for example. The superimposed information is, for example, information on the status of the elevator 1 distributed from the monitoring center 17, information on the status of the elevator 1 stored in the storage unit 12, or information such as weather information distributed from the distribution center 16. There may be.

Further, the distribution destination to which the image data processing device 5 distributes moving images is not limited to the monitoring center 17 . For example, the image data processing device 5 may accept a distribution start request and a distribution stop request from an information terminal used by a building manager or the like. At this time, the image data processing device 5 delivers moving image data to the information terminal. Here, the information terminal includes, for example, a stationary personal computer, or a portable device such as a smart phone or a tablet computer. Further, the image data processing device 5 may receive a distribution start request and a distribution stop request from a maintenance terminal possessed by a maintenance worker or the like who performs maintenance work on the elevator 1 . At this time, the image data processing device 5 distributes the moving image data to the maintenance terminal. Incidentally, when the maintenance terminal is connected to the monitoring center 17 via the network 15, the image data processing device 5 may distribute the moving image captured by the in-car camera 7 to the monitoring center 17 via the maintenance terminal. .
