When the control device 12 receives the image request transmitted by the communication unit 23 in S103, a determination of Yes is made in S201.

If it is determined as Yes in S201, the extracting unit 16 extracts images necessary for inspecting the camera 10 from the recorder 11 (S202). In S<b>202 , the extraction unit 16 extracts from the recorder 11 at least the first image and the second image different from the first image. The first image is part of the moving image stored in the recorder 11 . The second image is another portion of the moving image stored in the recorder 11 . Each of the first image and the second image is preferably a moving image, that is, an image of a plurality of frames. Each of the first image and the second image may be only an image (still image) for one frame constituting a moving image.

Conditions for the extraction unit 16 to extract an image are set in advance. It is preferable that there is a certain interval or more between the date and time when the first image was captured and the date and time when the second image was captured. As an example, the extraction unit 16 extracts the first image so that the oldest still image among the still images forming the moving image stored in the recorder 11 is included in the first image. The extraction unit 16 extracts the second image so that the second image includes the latest still image among the still images forming the moving image stored in the recorder 11 . The extraction unit 16 may extract the first image and the second image based on other conditions.

In the following, as a preferred example, an example in which the extraction unit 16 extracts the third image from the recorder 11 in addition to the first image and the second image in S202 will be described. The third image is another part of the moving image stored in the recorder 11 and is an image different from the first image and the second image. As an example, the extraction unit 16 extracts the third image so that the third image includes a still image captured at a date and time that is exactly in the middle between the date and time at which the first image was taken and the date and time at which the second image was taken. Extract. The extraction unit 16 may extract the third image based on other conditions.

In S203, the communication unit 17 transmits the image extracted by the extraction unit 16 in S202 to the portable terminal 13 that transmitted the image request in S201 (S203). The images transmitted to the mobile terminal 13 in S203 include at least the first image and the second image. In the example shown in this embodiment, the communication unit 17 sends the first image, the second image, and the third image extracted by the extraction unit 16 to the mobile terminal 13 as a response to the image request received in S201. Send.

As shown in FIG. 3, when the image request is transmitted to the control device 12 in S103, the mobile terminal 13 determines whether or not an image has been received from the control device 12 in response (S104). When the mobile terminal 13 receives the image transmitted from the communication unit 17 of the control device 12 in S203, it is determined as Yes in S104.

When it is determined as Yes in S104, the display control unit 24 displays the images received from the control device 12 side by side on the display device 21. FIG. In the example shown in this embodiment, the display control unit 24 displays the first image, the second image, and the third image side by side on the display device 21 . The first image, the second image, and the third image are preferably arranged in order of date and time when they were taken.

Thus, in the example shown in the present embodiment, the images extracted by the extraction unit 16 are displayed side by side on the display 21 of the mobile terminal 13 . A maintenance worker can inspect the camera 10 more efficiently by comparing and viewing the plurality of images displayed on the display 21 .

In the specific example shown in the present embodiment, the first image including the oldest still image, the second image including the latest still image, and the third image including the intermediate still image are displayed side by side on the display 21. be done. The maintenance personnel compares these three images while considering the passage of time, and confirms the quality of the images, the shooting angle, and the like. For example, when an image is slightly cloudy, it is difficult to notice that the quality of the image has deteriorated just by looking at the image. By comparing old and new images, it becomes easier to notice such changes in image quality.

Note that the recorder 11 is often owned by the owner of the building in which the elevator is installed. Therefore, it is not preferable for maintenance personnel to see the images themselves stored in the recorder 11 . Therefore, the image that the communication unit 17 of the control device 12 transmits to the mobile terminal 13 in S203 is preferably an image that has undergone mosaic processing. In the specific example shown in this embodiment, each of the first image, the second image, and the third image is preferably an image subjected to mosaic processing. In such a case, the display control unit 24 arranges and displays a plurality of mosaic-processed images on the display 21 in S105.

In this embodiment, an example in which the control device 12 is provided on the car 1 has been described. Alternatively, controller 12 may be provided as part of monitoring device 8 . In such a case, the maintenance worker first connects the mobile terminal 13 to the monitoring device 8 upon arrival at the hall 14 .

When the monitoring device 8 monitors a plurality of elevators, maintenance personnel may input an identification number for identifying the recorder 11 when connecting the portable terminal 13 to the monitoring device 8 . The identification number may be a combination of the building number and the unit number. Accordingly, an image necessary for inspecting the camera 10 can be acquired from one of the plurality of recorders 11 that are monitored by the monitoring device 8 .

In the present embodiment, an example has been described in which the conditions for extracting images by the extracting unit 16 are set in advance. That is, in the example shown in the present embodiment, it is not necessary for the maintenance personnel to select the image extracted by the extraction unit 16, and if the start condition is satisfied, the image necessary for inspecting the camera 10 is displayed on the display 21. displayed automatically.
