In addition, the virtual graphic screen displayed by the image processing unit 300 on the monitor unit 100 may include a graphic image stored in advance.

As such, since the image processing unit 300 provides the first external image and the second external image to the occupant through the monitor unit 100 , there is an effect that the occupant feels less closed and stuffy.

Also, the image processing unit 300 may display the virtual object VO on the monitor unit 100 together with the external image so that the occupant of the elevator assembly 1 can feel the boundary between the inside and the outside of the elevator 10 . In this specification, the virtual object VO may include an image that gives an effect of giving a sense of boundary between the inside and the outside of the elevator 10 . For example, the virtual object VO is displayed on the monitor unit 100 , but gives a three-dimensional effect, such as a virtual object approaching toward the side wall unit 12 from a point far away from the elevator 10 . It may be an image that As a more detailed example, a plurality of virtual objects VO may be provided, and the plurality of virtual objects VO may be one of falling raindrops, scattered snowflakes, and flying foreign objects (eg, soil, sand, dust, fine dust). may include more than one.

As another example, the virtual object VO may include an image placed on the virtual surface or moving on the virtual surface in order to give an effect of giving a sense of boundary between the inside and the outside of the elevator 10 . As a more detailed example, the virtual object VO may include one or more of raindrops formed on the virtual surface, snowflakes formed on the virtual surface, and foreign substances attached to the virtual surface. Also, the virtual object VO may include water droplets that are formed on the virtual surface and then flow along the virtual surface. Here, the virtual surface means a surface parallel to the first monitor 110 and a surface parallel to the second monitor 120 . These virtual surfaces may be spaced apart from the first monitor 110 and the second monitor 120 within a predetermined adjacent distance. For example, the virtual surface may be a surface spaced apart by 50 cm from the first monitor 110 and the second monitor 120 . Hereinafter, a virtual surface parallel to the first monitor 110 or having a predetermined inclination with respect to the first monitor 110 is defined as a first virtual surface (not shown). In addition, a surface parallel to the second monitor 120 or having a predetermined inclination with respect to the second monitor 120 is defined as a second virtual surface (not shown).

As such, the image processing unit 300 monitors the three-dimensional effect such as the virtual object VO approaches the virtual surface through the virtual object VO, is formed on the virtual surface, and flows through the virtual surface. 100) can be expressed. Due to this, the occupant sees the virtual object VO and the external image, and can recognize that the space where the occupant stays is cut off from the outside by the elevator 10 , and a sense of boundary between the inside and the outside of the elevator 10 . be able to feel In addition, the occupant does not feel anxiety such as acrophobia, and there is an effect that the occupant does not feel a sense of closedness by observing the external view.

Meanwhile, the image processing unit 300 may move the virtual object VO within the monitor unit 100 . The image processing unit 300 may move the virtual object VO from one point to another while the external image is being played, for example, to move the virtual object VO from the upper side to the lower side of the monitor unit 100 . can be displayed. Also, the image processing unit 300 may display the virtual object VO on the monitor unit 100 so that the virtual object VO moves on a second virtual surface having a predetermined inclination with respect to the moving direction of the elevator 10 . In this case, the second virtual surface may be referred to as a virtual inclined surface. As a more detailed example, the image processing unit 300 may display an image of raindrops falling toward the second virtual surface on the second monitor 120 . In this case, the image processing unit 300 may sequentially display the raindrops formed on the second virtual surface and the raindrops flowing from the upper side to the lower side on the second virtual surface on the second monitor 120 . Also, the image processing unit 300 may display raindrops flowing from the upper side to the lower side on the first monitor 110 on the first virtual surface.

In this way, even if the second monitor 120 extends in the horizontal direction, the virtual object VO is displayed as if it flows along the slope, so that the raindrops expressed on the second monitor 120 move from the top to the bottom on the slope by gravity. it will look like In addition, the raindrops displayed on the first monitor 110 also appear to move from the upper side to the lower side on the first virtual surface due to gravity. Due to this, there is an effect that the occupant more and more believes that the inner space of the elevator 10 is blocked from the outside.

In addition, the image processing unit 300 may move the virtual object VO so as to pass through a passing point while moving from the upper side to the lower side of the monitor unit 100 . For example, the via point may be located on the upper edge of the first monitor 110 or the lower edge of the second monitor 120 . Accordingly, the image processing unit 300 moves the virtual object VO moving from the upper side to the lower side on the second monitor 120 to the lower edge of the second monitor 120 . Also, the image processing unit 300 moves the virtual object VO downward from the upper edge of the first monitor 110 .

In addition, the image processing unit 300 frames a portion of the virtual object VO framed out from the second monitor 120 to the first monitor 110 through only the upper edge of the first monitor 110 . can do it Here, the frame-out means that the virtual object VO goes out from inside the screen of the monitor unit 100 , and the frame-in means that the virtual object VO comes in from outside the screen of the monitor unit 100 . As a more detailed example, raindrops from the upper side to the lower side riding on the inclined surface displayed on the second monitor 120 are framed out and disappear when they reach the lower edge portion of the second monitor 120 . In addition, the framed portion of the raindrops are framed from the upper edge of the first monitor 110 and displayed on the first monitor 110 , and the raindrops flowing from the upper side to the lower side are sequentially displayed on the first monitor 110 . .

As such, the image processing unit 300 may provide the occupant with the effect that the virtual object VO displayed on the second monitor 120 continuously moves from the second monitor 120 to the first monitor 110 . have. Accordingly, the raindrops expressed from the second monitor 120 are seen by the passenger as if they continuously ride and flow on surfaces having different inclination angles (sloping surface and vertical surface). Due to this, there is an effect that the occupant more and more believes that the inner space of the elevator 10 is blocked from the outside.

Meanwhile, the image processing unit 300 may display the virtual object VO on the monitor unit 100 so that the virtual object VO moves in a direction different from the moving direction of the elevator 10 and moves at a speed different from the moving speed of the elevator 10 . have. Also, the image processing unit 300 may display the virtual object VO on the monitor unit 100 so that the virtual object VO moves in a direction different from the changing direction of the external foreground and moves at a speed different from the moving speed of the external foreground. For example, when the elevator 10 rises, the exterior foreground changes corresponding to the elevation of the elevator 10 . In this case, the image processing unit 300 displays the virtual object VO descending independently of the change of the external foreground, and the virtual object VO descending at a different speed than the ascending speed of the elevator 10 on the monitor unit 100 . can do.

The image processing unit 300 may change the moving speed of the virtual object VO based on the speed of the elevator 10 . For example, when the speed of the elevator 10 increases, the image processing unit 300 may increase the moving speed of the virtual object VO in the monitor unit 100 . As a more detailed example, when the elevator 10 rises, the image processing unit 300 may display it on the monitor unit 100 so that the speed of the virtual object VO gradually increases as the rising speed of the elevator 10 increases. have. As another example, when the elevator 10 descends, the image processing unit 300 may display on the monitor unit 100 such that the velocity of the virtual object VO gradually decreases as the descending velocity of the elevator 10 increases. .
