In this universal display, the display area is reduced as compared with the normal display. That is, unlike the normal display described above, the direction display 17, floor display 18, and destination floor registration button 20 display a large display content and eliminate or minimize the dynamic display such as animation display. , Display is given priority to ease of viewing and understandability over design.

  Next, switching control between the normal display and the universal display by the video processing unit 7 will be described using the flowchart of FIG.

  The video processing unit 7 performs switching control based on the video signal from the camera 11 connected to the video processing unit 7. First, the video processing unit 7 receives a video signal from the camera 11 and performs camera video analysis processing (S1). It is determined from the analyzed video whether there is a user facing the elevator direction at the hall (S2). If it is determined that there is no user trying to use the elevator at the landing (NO in S2), the process returns to step 1 (S1) to perform camera image analysis processing. On the other hand, when it is determined from the analyzed video that there is a user facing the elevator direction at the hall, that is, when it is determined that there is a user who is going to use the elevator (YES in S2), the display unit 9 The liquid crystal backlight is turned on and the brightness is increased (S3). On the other hand, when it is determined that there is no user, the liquid crystal backlight and the light emission luminance are turned off or minimized.

  Next, the video processing unit 7 performs face detection processing based on the video signal from the camera 11 (S4). The face detection process is a process of grasping the position of a person's face outline, eyes, nose, and the like from a camera image, and detecting and judging the face as a person.

  After the face is determined by the face detection process, the face detection is used to detect how close the elevator user is to the display device. Specifically, it is determined whether or not the detected face has approached by a certain distance (S5). When it is determined that a certain distance has been approached (YES in S5), display pattern switching processing of the display device is performed (S6). That is, the display content of the flat panel display 8 is switched from the normal display to the universal design display.

  In such a display pattern switching process, when the distance from the camera 11 installed on the flat panel display 8 to the user's face is detected and the face is brought closer than a certain distance, the user is a low vision person. It is determined that the display screen of the universal design display of FIG. 3 that does not perform character size expansion or animation is easier to use than the display screen of the normal display as shown in FIG. Because.

  After switching the display pattern, the user determines whether or not the face has been brought closer than the predetermined distance (S7). When it is determined that the face is further closer than the predetermined distance (YES in S7), a screen display enlargement process for further enlarging and displaying the screen display of the universal design display is performed (S8). The screen display enlargement process enlarges and displays a part of the universal design display shown in FIG. In this method, when the face is brought closer than the above-mentioned fixed distance, a part of the screen display is enlarged according to the detected position of the face. For example, when the user determines that his / her face is close to the destination floor registration button, the destination floor registration button (area B) portion is enlarged and displayed. After the screen display enlargement process is performed, the process returns to step 7 (S7).

  On the other hand, after switching the display pattern, if it is not determined that the user has moved the face further than the above-mentioned fixed distance (NO in S7), it is determined whether the user has moved the face away from the camera 11 by a fixed distance. (S9). If it is determined that the user has not moved away from the camera 11 by a certain distance (NO in S9), the process returns to step 7 (S7) to continue the universal design display and whether to perform the screen display enlargement process. Repeat judgment.

  On the other hand, if it is determined that the user has moved away from the camera 11 by a certain distance, the user determines that the target operation has been completed, and switches the display method to normal display (S10). Since it is necessary to display the state of the elevator or provide a function as a destination floor registration button or the like to other users, the display is switched to the normal display.

  As described above, according to the first embodiment of the present invention, the display contents can be switched to appropriate display contents according to the elevator user, and any display device can be provided without providing a separate display device dedicated to the disabled person. Even so, it is easy to see and easy to use.

(Second Embodiment)
Next, a second embodiment will be described. FIG. 5 is a schematic view showing a configuration of a display device according to the second embodiment of the present invention. FIG. 6 is a flowchart showing display switching control according to the second embodiment of the present invention.

This will be specifically described below with reference to FIGS.

  First, the elevator control device 5 determines whether or not the wheelchair user registration button 21 installed at the landing is operated (S21). When it is determined that the wheelchair user registration button 21 is not operated (NO in S21), the elevator control device 5 performs processing while continuing normal display without changing the display content of the flat panel display 8 to universal design display. Is finished (S26).

  On the other hand, when it is determined that the wheelchair user registration button 21 has been operated (YES in S21), the elevator control device 5 determines whether the car has arrived on the registration floor and the user has entered the car (S22). ). After operating the wheelchair user registration button 21, if it is determined that the user is not in the car (NO in S22), the display content of the flat panel display 8 is not changed to the universal design display, and the normal display is continued. The process is terminated as it is (S26).

  On the other hand, if it is determined that the user has entered the car after operating the wheelchair user registration button 21 (YES in S22), the display pattern of the display device is switched from the normal display to the universal design display ( S23). Then, the destination floor registered by the boarded user is detected by the in-car destination floor registration device (S24). Further, the elevator control device 5 determines whether or not the car has arrived at the destination floor (S25). If it has not arrived at the destination floor (NO in S25), the display pattern of the display device is continued in the universal design display.

  On the other hand, when arriving at the destination floor (YES in S25), the display content of the display device is switched from the universal design display to the normal display (S27).

  As described above, by switching the display of the in-car display device depending on whether or not the wheelchair user registration button 21 installed in the hall is operated, the display contents of the display device are already displayed when the user enters the car 1. Since the display is switched, the display contents are easier to see and operate.
