4 to 6, the casing 2 of the imaging unit 11b is used.
21 is shown in cross section, but only a part of the internal structure is shown in cross section. In FIG. 4, the cross section of the optical component is shown without parallel oblique lines. In FIG. 6, members in the depth direction are omitted as appropriate.

As shown in FIG. 4, a movable first lens 31a and a second lens 31b constituting a photographic optical system are arranged in an image pickup section 11a in which a zoom mechanism 11b is incorporated, and these are holders. 32a and 32b. As shown in FIG. 5, drive shafts 331a and 331b for driving the lens are disposed above the lens. As shown in FIGS. 5 and 6, the holder 32a and the drive shaft 331a are in sliding contact with each other. The holder 32b and the drive shaft 331b are slidably connected by
21b slidably connected. Thereby, the first
When a force equal to or more than a predetermined value acts on both the lens 31a and the second lens 31b, the lens 31a and the second lens 31b move along the drive shafts 331a and 331b. Further, as shown in FIGS. 4 and 6, a first lens 31a is provided below the holders 32a and 32b.
And a guide shaft 34 for guiding the movement of the second lens 31b
Is arranged.

One end (the left end in FIG. 5) of the drive shafts 331a and 331b is restricted only in a direction other than the axial direction, and the other end (the right end in FIG. 5) is connected to the piezoelectric elements 332a and 332a.
32b. The piezoelectric elements 332a and 332b are elements that expand and contract in the drive axis direction when a voltage is applied, and are elements that convert the voltage into displacement of a connection surface with the drive shaft.

An optical low-pass filter 37 is further mounted on the upper side. Thus, the light incident from the opening 222 enters the CCD 36 via the first lens 31a, the second lens 31b, and the optical low-pass filter 37. At this time, by driving the piezoelectric elements 332a and 332b, the movement of the first lens 31a and the second lens 31b is controlled as described later, and an image of the subject is appropriately formed on the CCD 36.

As shown in FIGS. 4 and 6, each of the holders 32a and 32b has a pedestal at a lower portion, and magnets 322a and 322b are attached to the ends thereof. Then, the magnetic sensor 3 mounted in the casing 211

a and the drive shaft 331a do not slip.
The lens 31a moves toward the opening 222 together with the drive shaft 331a. On the other hand, when the voltage sharply decreases, a force greater than the maximum static friction force is generated between the sliding contact member 321a and the drive shaft 331a, and a slip occurs between the holder 32a and the drive shaft 331a. The first lens 31a does not move toward the CCD 36 as much as the drive shaft 331a. as a result,
When the gradual extension and the steep contraction of the piezoelectric element 332a are repeated, the first lens 31a moves to the opening 222 side.

Conversely, when the sawtooth wave shown in FIG. 8 is applied to the piezoelectric element 332a, the first lens 31a moves to the CCD 36 side. Similarly, the driving of the second lens 31b is performed by applying a sawtooth wave to the piezoelectric element 332b. At this time, the positions of the first lens 31a and the second lens 31b are detected by the magnetic sensors 38a and 38b.
Drive control of these lenses is performed.

As a result, as shown in FIGS. 4 to 6, the image pickup section 11a has a structure having two sets of lenses, a drive shaft, a piezoelectric element, and a sliding member (or a structure having three or more sets). By doing so, a zoom function is realized despite its small size.

In order to reduce the imaging magnification (to obtain a wide viewing angle), a magnification control signal for controlling each imaging device 11 is transmitted to the local system 3 via the communication device 45. Thus, when the number of passengers is large in each monitoring area, each imaging device 11 automatically changes the imaging magnification to a low imaging magnification (wide-angle viewing angle), while the number of passengers in each monitoring area increases. When the number is small, the imaging magnification is automatically changed to a high imaging magnification (telephoto viewing angle).

When the number of passengers is small and the passengers are sparsely scattered in distant positions in the cabin 1a, setting the imaging magnification to a high imaging magnification allows the passengers in each monitoring area to be displayed on one screen. In such a case, it is difficult to take an image at one time, but in such a case, the image pickup unit 11a is automatically swung in the pan or tilt direction by a command given from the camera control unit 41b that has detected this. It is preferable that the image capturing apparatus 11 cyclically captures images of all areas in each monitoring area.

The occurrence of a specific situation (a lost object in this case) registered in advance, such as an act, is detected, and the occurrence of the specific situation is notified to the monitoring person via the notification device 49. The details of the lost object detection processing by the monitoring processing unit 41c will be described later based on the flowchart of FIG.

In step S45, the presence or absence of a passenger getting off the moving body 1 is determined based on the image of each imaging device 11, and if there is a passenger getting off, the process proceeds to step S46. Proceed to step S11. Here, as shown in FIG. 15, the presence or absence of a passenger getting off the vehicle is determined by setting the boarding opening 1c with the opening / closing door 1d open (here, the area inside the cabin 1a of the boarding opening 1c) above the boarding gate 1c in the cabin 1a. The passenger 63 approaching the direction of the imaging device 11 (the boarding gate 1c) based on the captured image 61 (see FIG. 16) captured by the imaging device 11 installed at the position.
The determination is made based on whether or not there is an error (that is, whether or not there is an image 65 of the person 63 whose image gradually increases in the captured image 61). That is, when there is a person 63 approaching the imaging device 11, the person is determined to be a passenger boarding the moving body 1.

In step S46, the passenger 6 who has been determined to be the passenger 63 who gets off the moving body 1 in step S45.
The passenger information at the time of getting off is created based on the image 61 in which the image No. 3 is captured, and the process proceeds to step S47.

Here, the getting-off passenger information includes the passenger identification information and the baggage information extracted from the image 61.
The passenger identification information is the passenger identification information for identifying the passenger 53, and is created in the same manner as the passenger identification information of the above-described on-board passenger information. Here, the head of the passenger 63 in the image 61 (here, In this case, the information indicates the facial features of the passenger 63 extracted from the area 61a including the face 63a. The luggage information is information on luggage carried by the passenger 63 (here, luggage identification information for identifying the presence or absence of luggage and luggage (here, the type of luggage)) and is extracted from the image 61. . The method of detecting the presence / absence of luggage and the type of luggage is the same as in the case of luggage information in the above-described on-board passenger information.

In step S47, the passenger identification information of the same person's getting-on passenger information that matches the getting-off passenger information extracted in step S46 is retrieved from the database of the recording device 41d, and the passenger identification information matches.
