Abstract

An elevator display system includes: a sensing device that acquires sensing data indicating condition of an inside of a cage; a mirror display device arranged in the cage on a side opposite to an elevator door, functions in a first state as a mirror, and functions in a second state as an image display unit; a content generation unit that generates display image data to be displayed on the mirror display device; an in-cage condition judgment unit that judges condition of a user in the cage from the sensing data and outputs user information regarding the condition of the user; and a display control unit that outputs a control signal requesting generation of display image data for setting a display state of a display surface of the mirror display device to the first state or the second state to the display image generation unit based on the user information.

First claim

What is claimed is:

1. An elevator display system comprising:
a sensor to acquire sensing data indicating condition of an inside of a cage of an elevator by photographing or detecting the condition of the inside of the cage;
a mirror display arranged in the cage on a side opposite to an elevator door, the mirror display functioning in a first state of being a mirror by displaying an image based on predetermined image data and functioning in a second state of being an image display by displaying an image based on display image data other than the predetermined image data;
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs
a display image generation process of generating the display image data to be displayed on the mirror display;
an in-cage condition judgment process of judging condition of a user in the cage from the sensing data and outputting user information regarding the condition of the user;
a display control process of outputting a control signal requesting generation of the predetermined image data for setting a display state of a whole or part of a display surface of the mirror display to the first state or a control signal requesting generation of the display image data for setting the display state to the second state based on the user information, and
an exit floor determining process of determining whether the cage has arrived at an exit floor,
wherein the in-cage condition judgment process includes:
determining whether or not the user includes a wheelchair user; and
determining whether or not the wheelchair user is facing the mirror display, and

wherein the program causes the mirror display to function in the first state when the cage is determined to have arrived at the exit floor and the wheelchair is determined to be facing the mirror display.

2. The elevator display system according to claim 1 , wherein the first state is a state of displaying an image filled in with a particular color on the mirror display.

3. The elevator display system according to claim 1 , wherein the program which, when executed by the processor, further performs setting the mirror display to the first state at least for a period in which the elevator door is open in a case where the wheelchair user exists in the cage and the wheelchair user is facing the mirror display.

4. The elevator display system according to claim 1 , wherein
the program which, when executed by the processor, further performs an exit floor registration process in which the user registers an exit floor,
the in-cage condition judgment process includes acquiring identification information on the wheelchair user, and
the user information includes exit floor information acquired in the exit floor registration process, the judgment information indicating whether or not the wheelchair user is facing the mirror display, and the identification information on the wheelchair user in a form of being associated with each other.

5. The elevator display system according to claim 4 , wherein the display control process includes setting the mirror display to the first state at least for a period in which the elevator door is open in a case where the wheelchair user exists in the cage, the wheelchair user is facing the mirror display, and the wheelchair user arrives at the exit floor.

6. The elevator display system according to claim 5 , wherein
the exit floor registration process is performed through one of a first unit arranged for a general user and a second unit arranged for a wheelchair user, the first unit and the second unit being separated from each other, and
control in the display control process is performed while only an exit floor is inputted through the second unit by the wheelchair user.

7. The elevator display system according to claim 1 , wherein
the program which, when executed by the processor, further performs an operation mode acquisition process of generating operation mode information on the elevator,
the in-cage condition judgment process operates when the operation mode information indicates a wheelchair operation mode as an operation mode in a case where the wheelchair user exists in the cage, and does not operate when the operation mode information indicates an operation mode other than the wheelchair operation mode, and
the display control process includes setting the mirror display to the first state when the operation mode is an absence mode as an operation mode in a case where no user exists in the cage, and setting the mirror display to the second state when the operation mode is not the wheelchair operation mode or the absence mode.

8. The elevator display system according to claim 5 , wherein the display image generation process includes making a part of the mirror display display an image based on content in a case where the display control process includes judging that the mirror display is set to the first state when the wheelchair user exits from the cage.

9. The elevator display system according to claim 1 , further comprising an exit floor camera that photographs an outside of the cage,
wherein the display image generation process includes making a part of the mirror display display an image acquired by the exit floor camera in a case where the display control process includes judging that the mirror display is set to the first state when the wheelchair user exits from the cage.

10. The elevator display system according to claim 1 , wherein
the program which, when executed by the processor, further performs a current floor information acquisition process of acquiring a current position of the cage in an elevator shaft, and
the display image generation process includes making the mirror display display current floor information acquired in the current floor information acquisition process.

11. The elevator display system according to claim 1 , further comprising a database that stores the content, including a material being a still image, motion video, graphics, a character string or a figure and formed of the material and arrangement information on the material, and playback timing information indicating timing of displaying the content on the mirror display,
wherein the display image generation process includes supplying display image data based on the content acquired from the database to the mirror display with timing based on the playback timing information.

12. An elevator display system comprising:
a sensor to acquire sensing data indicating condition of an inside of a cage of an elevator by photographing or detecting the condition of the inside of the cage;
a mirror display arranged in the cage on a side opposite to an elevator door, the mirror display functioning in a first state of being a mirror and functioning in a second state of being an image display by displaying an image based on display image data;
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs
a display image generation process of generating the display image data to be displayed on the mirror display;
an in-cage condition judgment process of judging condition of a user in the cage from the sensing data and outputting user information regarding the condition of the user; and
a display control process of outputting a control signal for setting a display state of a whole or part of a display surface of the mirror display to the first state or a control signal for setting the display state to the second state to the mirror display based on the user information, and
an exit floor determining process of determining whether the cage has arrived at an exit floor
