Description

Technical Field

[0001] The present disclosure relates to a simulation window unit and a simulation window. Background Art

[0002] A simulated window unit is known, for example, for installation in a room where windows are not possible due to structural reasons (see, for example, Patent Document 1). Conventional simulated window units include a window frame disposed on a wall of an indoor space and an image display device disposed opposite an opening in the window frame. The image display device captures a scene that would be visible from an actual window, i.e., a landscape image, and displays it to the indoor space through the opening in the window frame.

[0003] Therefore, the scenery image reflected from the simulated window unit looks like the scenery viewed from an actual window, so it is possible to eliminate the feeling of being closed in a room where windows cannot be installed.

[0023] In addition, the inventors provide the drawings and the following description to enable those skilled in the art to fully understand the present disclosure, and their intention is not to limit the subject matter described in the technical solution.

[0024] (Implementation Method)

[0025] Reference below Figures 1 to 9 To illustrate the implementation method. Figures 1 to 4 as well as Figures 7 to 9 , the width direction (left-right direction) of the simulation window unit 2 is set as the X-axis direction, the depth direction of the simulation window unit 2 is set as the Y-axis direction, and the height direction (up-down direction) of the simulation window unit 2 is set as the Z-axis direction.

[0026] [1. Overview of Simulated Window Unit]

[0027] First, refer to Figure 1 , an overview of the simulated window unit 2 according to the embodiment will be described. Figure 1 1 is a diagram showing an outline of a pseudo window unit 2 according to the embodiment.

[0028] like Figure 1 As shown, the simulated window unit 2 includes a camera 4 , a controller 6 , an image display device 8 , and a simulated window 10 .

[0029] The camera 4 is arranged outside the building 12 and generates a landscape image, which is, for example, an image (moving image) of an outdoor landscape 14 photographed in a southerly direction. The camera 4 is capable of communicating with the controller 6 and transmitting the generated landscape image to the controller 6. The outdoor landscape 14 photographed by the camera 4 may be, for example, a) natural landscapes such as mountains, rivers, forests, and seashores, or b) landscapes of artificial structures such as skyscrapers, gardens, and bridges. In addition, the camera 4 transmits photography condition information (described later) related to the photography conditions of the landscape image to the controller 6. In addition, in this embodiment, the camera 4 is arranged outside the building 12, but this is not limited to this. For example, the camera 4 may be arranged inside the building 12 and the outdoor landscape 14 may be photographed by the camera 4 through the window of the building 12.

[0030] Controller 6 is located in indoor space 16 of building 12 and controls image display device 8 and simulated window 10. Controller 6 receives a landscape image transmitted from camera 4 and outputs the received landscape image to image display device 8. Controller 6 also receives photographic condition information transmitted from camera 4 and controls light source 36 (described later) of simulated window 10 based on the received photographic condition information.

[0031] Image display device 8 is a flat-panel display such as a liquid crystal display or an organic electroluminescence display, and is disposed in indoor space 16 of building 12. Image display device 8 includes a display surface 18 for displaying a landscape image output from controller 6. Specifically, landscape images captured by camera 4 are displayed in real time on display surface 18 of image display device 8.

[0032] The simulated window 10 is a structure that simulates an actual south-facing window, for example, and is disposed in an indoor space 16 of a building 12. The simulated window 10 is disposed so as to face a display surface 18 of the image display device 8.

[0033] The user can view the landscape image displayed on the display surface 18 of the image display device 8 through the simulated window 10 and feel as if he or she is looking at the outdoor landscape 14 through a real window.

[0034] [2. Structure of the Simulated Window Unit]

[0035] Next reference Figures 2 to 4 , the structure of the simulation window unit 2 in the embodiment is described. Figure 2 It is a perspective view showing the structure of the pseudo window unit 2 according to the embodiment. Figure 3 It is along Figure 2 FIG. 4 is a cross-sectional view of a simulated window unit 2 according to an embodiment of the present invention taken along line III-III. Figure 4 It is along Figure 2 The cross-sectional view of the simulated window unit 2 of the embodiment of the IV-IV line. Figure 2 Part of the wall portion 20 is omitted in the figure.

[0036] like Figures 2 to 4 As shown, the image display device 8 and the simulated window 10 of the simulated window unit 2 are arranged on a wall portion 20 of the indoor space 16. The wall portion 20 is composed of an inner wall portion 22 facing the indoor space 16 and an outer wall portion (not shown) facing the outdoor side relative to the inner wall portion 22. The indoor space 16 is a space surrounded by the inner wall portion 22, such as a living room. The inner wall portion 22 has a through hole 24 formed therein for installing the simulated window 10. The through hole 24 is formed into a rectangular shape in the XZ plane.

[0037] like Figures 2 to 4 As shown, image display device 8 is disposed in wall space 26 between inner wall portion 22 and outer wall portion, and is supported by a support mechanism (not shown) at a height corresponding to the height position (position in the Z-axis direction) of simulation window 10. Display surface 18 of image display device 8 is disposed so as to face through-hole 24 of inner wall portion 22.

[0038] like Figures 2 to 4 As shown, the simulated window 10 includes a window frame 28 , a sash 30 (an example of a light shielding member), a window plate 32 , a support frame 34 , and a light source 36 .

[0039] The window frame 28 is a frame member that imitates the window frame of an actual window. The window frame 28 is formed into a rectangular shape in the XZ plane view and is arranged at the edge of the through hole 24 of the inner wall portion 22. In other words, the window frame 28 is arranged so as to face the display surface 18 of the image display device 8. The window frame 28 is formed by the upper side horizontal frame 28a (refer to Figure 2 as well as Figure 3 ), the lower side of the horizontal frame 28b (reference Figure 2 as well as Figure 3 ), the left vertical frame 28c (reference Figure 2 as well as Figure 4 ) and the right vertical frame 28d (reference Figure 2 as well as Figure 4) is configured in a rectangular shape. The upper side, lower side, left side and right side here refer to the upper side (positive side of the Z axis), lower side (negative side of the Z axis), left side (negative side of the X axis) and right side (positive side of the X axis) when facing the simulation window 10 from the indoor space 16, respectively. In the area surrounded by the upper horizontal frame 28a, the lower horizontal frame 28b, the left vertical frame 28c and the right vertical frame 28d, an opening portion 38 that is rectangular in the XZ plane view is formed. The window frame 28 is formed, for example, by a decorative panel. In addition, in the XZ plane view, the size of the window frame 28 is smaller than the size of the display surface 18 of the image display device 8.

[0040] The sash 30 is a frame member for supporting the window panel 32. The sash 30 is formed into a rectangular shape in the XZ plane view and is arranged on the inner peripheral surface of the window frame 28. More specifically, Figure 3 as well as Figure 4 As shown, the frame 30 is arranged at the end portion of the inner peripheral surface of the window frame 28 close to the image display device 8. The frame 30 is connected to the image display device 8 by the upper horizontal frame 30a (refer to FIG. Figure 3 ), the lower horizontal frame 30b (reference Figure 2 as well as Figure 3 ), the left vertical frame 30c (reference Figure 2 as well as Figure 4 ) and the right vertical frame 30d (reference Figure 4 ) is arranged in a rectangular shape. The sash 30 extends radially inward from the inner circumference of the window frame 28. The radial inward refers to the direction from the inner circumference of the window frame 28 toward the center of the opening 38. The sash 30 is made of a light-shielding material, such as a metal such as aluminum.

[0041] The window panel 32 is a panel member that mimics the glass window of an actual window. The window panel 32 is formed into a rectangular shape in an XZ plane view and is positioned to cover the opening 38 of the window frame 28. The outer periphery of the window panel 32 is supported by the sash 30. The window panel 32 is formed from a light-transmitting material, such as a transparent acrylic plate or glass plate.

[0042] The support frame 34 is a frame member for supporting the light source 36. The support frame 34 is formed into a rectangular shape in the XZ plane view and is arranged between the window frame 28 and the image display device 8 along the circumferential direction of the window frame 28. In addition, the circumferential direction refers to the direction along the inner circumference or outer circumference of the window frame 28 in a cross section perpendicular to the axial direction (Y-axis direction) of the window frame 28. The support frame 34 is formed by the upper side transverse frame 34a (refer to Figure 2 as well as Figure 3 ), the lower horizontal frame 34b (reference Figure 2 as well as Figure 3 ), the left vertical frame 34c (reference Figure 2as well as Figure 4 ) and the right vertical frame 34d (reference Figure 2 as well as Figure 4 The upper horizontal frame 34a, lower horizontal frame 34b, left vertical frame 34c, and right vertical frame 34d of the support frame 34 are arranged along the upper horizontal frame 28a, lower horizontal frame 28b, left vertical frame 28c, and right vertical frame 28d of the window frame 28, respectively.

[0043] The light source 36 is a light source that emits light that simulates sunlight and illuminates the indoor space 16. Figure 2 As shown, the light source 36 includes an upper left light source 40 (an example of a first light source), an upper right light source 42 (an example of a first light source), a lower left light source 44 (an example of a second light source), and a lower right light source 46 (an example of a third light source).

[0044] like Figure 3 As shown in FIG. 4 , the upper left light source 40 has an elongated substrate 48 and a plurality of LEDs 50 (Light Emitting Diodes) arranged and mounted in the longitudinal direction (X-axis direction) of the substrate 48. Figure 3 As shown, the upper right light source 42 has an elongated substrate 52 and a plurality of LEDs 54 mounted along the longitudinal direction (X-axis direction) of the substrate 52. The upper left light source 40 and the upper right light source 42 are arranged on the inner circumference of the upper horizontal frame 34a of the support frame 34, and are arranged in an elongated shape along the longitudinal direction (X-axis direction) of the upper horizontal frame 34a. In other words, the upper left light source 40 and the upper right light source 42 are arranged along the upper horizontal frame 28a between the upper horizontal frame 28a of the window frame 28 and the image display device 8. At this time, the upper left light source 40 and the upper right light source 42 are arranged in a position that is invisible to users in the indoor space 16. In addition, the upper left light source 40 is arranged on the side close to the longitudinal frame 34c on the left side of the support frame 34, and the upper right light source 42 is arranged on the side close to the longitudinal frame 34d on the right side of the support frame 34.

[0045] like Figure 3 As shown, light from each of the upper left light source 40 and the upper right light source 42 passes through the opening 38 of the window frame 28 and is directed toward the interior space 16. At this time, a portion of the light from each of the upper left light source 40 and the upper right light source 42 is blocked by the upper horizontal frame 30a of the sash 30.

[0046] like Figure 4As shown, the lower left light source 44 includes an elongated substrate 56 and a plurality of LEDs 58 arranged and mounted along the lengthwise direction (Z-axis direction) of the substrate 56. The lower left light source 44 is arranged on the inner circumference of the left longitudinal frame 34c of the support frame 34, and is arranged in an elongated shape along the lengthwise direction (Z-axis direction) of the left longitudinal frame 34c. In other words, the lower left light source 44 is arranged between the left longitudinal frame 28c of the window frame 28 and the image display device 8, along the left longitudinal frame 28c. In this case, the lower left light source 44 is arranged in a position that is invisible to users in the interior space 16.

[0047] In addition, if Figure 4 As shown, the lower right light source 46 includes an elongated substrate 60 and a plurality of LEDs 62 arranged along the length (Z-axis) of the substrate 60. The lower right light source 46 is positioned on the inner circumference of the right longitudinal frame 34d of the support frame 34, and is arranged in an elongated shape along the length (Z-axis) of the right longitudinal frame 34d. Specifically, the lower right light source 46 is positioned between the right longitudinal frame 28d of the window frame 28 and the image display device 8, along the right longitudinal frame 28d. At this point, the lower right light source 46 is positioned in a position that is invisible to users in the interior space 16.

[0048] like Figure 4 As shown, light from lower left light source 44 and lower right light source 46 is emitted into interior space 16 through opening 38 of window frame 28. At this time, a portion of the light from lower left light source 44 is blocked by vertical frame 30c on the left side of sash 30. Furthermore, a portion of the light from lower right light source 46 is blocked by vertical frame 30d on the right side of sash 30.

[0049] [3. Functional structure of the controller]

[0050] Next reference Figure 5 , the functional structure of the controller 6 is explained. Figure 5 1 is a block diagram showing the functional configuration of the controller 6 of the pseudo window unit 2 according to the embodiment.

[0051] like Figure 5 As shown, the controller 6 includes an acquisition unit 64 and a control unit 66 as a functional structure.

[0052] The acquisition unit 64 acquires the landscape image sent from the camera 4. The acquisition unit 64 outputs the acquired landscape image to the image display device 8 via the control unit 66. As a result, the landscape image captured by the camera 4 is displayed on the display screen 18 of the image display device 8 in real time.

[0053] Furthermore, the acquisition unit 64 acquires the photographic condition information transmitted from the camera 4 and outputs the acquired photographic condition information to the control unit 66. The photographic condition information includes, for example, a) the date the landscape image was captured, b) the time the landscape image was captured, and c) the weather at the photography location when the landscape image was captured.

[0054] The control unit 66 controls the light source 36 of the simulated window 10 based on the imaging condition information output from the acquisition unit 64 .

[0055] Reference below Figures 6 to 9 , an example of control of the light source 36 by the controller 6 is described. Figure 6 1 is a diagram showing an example of control of the light source 36 by the controller 6 of the pseudo window unit 2 according to the embodiment. Figure 7 1 is a perspective view showing the simulated window unit 2 according to the embodiment when the image display device 8 displays a morning landscape image. Figure 8 1 is a perspective view showing the simulated window unit 2 according to the embodiment when the image display device 8 displays a landscape image at noon. Figure 9 It is a perspective view showing the pseudo window unit 2 according to the embodiment when the image display device 8 displays an image of an evening landscape.

[0056] First, refer to Figure 6 as well as Figure 7 , the case where the camera 4 captures a landscape image in the morning will be described. In this case, the time when the landscape image was captured in the photographing condition information acquired by the acquisition unit 64 includes a time in the morning time period (eg, 6:00 AM to 9:00 AM).

[0057] The control unit 66 controls the light source 36 based on the photographic condition information from the acquisition unit 64 so that the light from the light source 36 can imitate the refreshing sunlight in the morning. Figure 6 As shown, the control unit 66 controls the lower left light source 44 to be turned on and the upper left light source 40, the upper right light source 42, and the lower right light source 46 to be turned off based on the imaging condition information from the acquisition unit 64. Furthermore, the control unit 66 controls the illuminance and color temperature of the light from the lower left light source 44 to be high illuminance and high color temperature, respectively, based on the imaging condition information from the acquisition unit 64.

[0058] In addition, the control unit 66 can also control the illuminance and color temperature of the light of the lower left light source 44 to illuminance and color temperature corresponding to the actual season and weather, etc., based on the date when the landscape image was taken and the weather at the photography location when the landscape image was taken, etc., which are included in the photography condition information.

[0059] Thus, if Figure 7As shown, a morning landscape image is displayed on the display surface 18 of the image display device 8. In addition, when viewed from the perspective of a user located in the indoor space 16, light with high illuminance and high color temperature from the lower left light source 44, which imitates the refreshing sunlight in the morning, shines onto the indoor space 16 through the opening 38 of the window frame 28 from the upper left side of the window frame 28. At this time, a portion of the light from the lower left light source 44 is blocked by the vertical frame 30c on the left side of the sash 30, thereby forming a shadow 68 of the vertical frame 30c on the left side of the sash 30 at one end portion in the longitudinal direction (X-axis direction) of the inner peripheral surface of the horizontal frame 28b on the lower side of the window frame 28. In addition, a shadow is also formed on the inner wall portion 22 of the indoor space 16. In addition, in Figure 7 As a result, it is possible to reproduce a state where the fresh morning sunlight enters the indoor space 16 from the east (negative side of the X axis) through the opening 38 of the window frame 28, thereby enhancing the sense of presence.

[0060] Next, refer to Figure 6 as well as Figure 8 , the case where a landscape image at noon or around noon is captured by the camera 4 will be described. In this case, the time when the landscape image was captured in the photographic condition information obtained by the acquisition unit 64 includes noon and the time period around noon (e.g., 9:00 a.m. to 3:00 p.m.).

[0061] The control unit 66 controls the light source 36 based on the photographic condition information from the acquisition unit 64 so that the light from the light source 36 imitates the sunlight at noon and before and after that, which represents the feeling of the season. Figure 6 As shown, the control unit 66 controls the upper left light source 40 and the upper right light source 42 to be turned on, and the lower left light source 44 and the lower right light source 46 to be turned off, based on the imaging condition information from the acquisition unit 64. Furthermore, the control unit 66 controls the illuminance and color temperature of the light from the upper left light source 40 and the upper right light source 42 to medium illuminance and medium color temperature, respectively, based on the imaging condition information from the acquisition unit 64.

[0062] In addition, the control unit 66 can control the illuminance and color temperature of the light of the upper left light source 40 and the upper right light source 42 to illuminance and color temperature corresponding to the actual season and weather, etc., based on the date when the landscape image was taken and the weather at the photography location when the landscape image was taken, etc., which are included in the photography condition information.

[0063] Thus, if Figure 8As shown, the display surface 18 of the image display device 8 displays a landscape image at noon. Furthermore, from the perspective of a user located in the indoor space 16, light of medium illuminance and medium color temperature, simulating the sunlight at noon, from the upper left light source 40 and the upper right light source 42, is emitted from directly above the window frame 28 through the opening 38 of the window frame 28 and into the indoor space 16. At this time, part of the light from the upper left light source 40 and the upper right light source 42 is reflected by the horizontal frame 30a on the upper side of the sash 30 (see FIG. 1 ). Figure 3 ) is blocked, so that a shadow 70 of the upper horizontal frame 30a of the sash 30 is formed at one end portion in the short direction (Y-axis direction) of the inner peripheral surface of the lower horizontal frame 28b of the window frame 28. In addition, a shadow is also formed on the inner wall portion 22 of the indoor space 16. Figure 8 As a result, it is possible to reproduce a state where the midday sunlight enters the indoor space 16 from the south (positive side of the Y axis) through the opening 38 of the window frame 28, thereby enhancing the sense of presence.

[0064] Finally, reference Figure 6 as well as Figure 9 , describing a case where an evening landscape image is captured by the camera 4. In this case, the photographing condition information acquired by the acquisition unit 64 includes a time in the evening time period (eg, 3 p.m. to 6 p.m.) as the time when the landscape image was captured.

[0065] The control unit 66 controls the light source 36 so that the light from the light source 36 imitates the setting sun at dusk based on the photographic condition information from the acquisition unit 64. Specifically, Figure 6 As shown, the control unit 66 controls the lower right light source 46 to be turned on and the upper left light source 40, the upper right light source 42, and the lower left light source 44 to be turned off based on the imaging condition information from the acquisition unit 64. Furthermore, the control unit 66 controls the illuminance and color temperature of the light from the lower right light source 46 to be low, respectively, based on the imaging condition information from the acquisition unit 64.

[0066] In addition, the control unit 66 can control the illuminance and color temperature of the light from the lower right light source 46 to illuminance and color temperature corresponding to the actual season and weather, etc., based on the date when the landscape image was taken and the weather at the photography location when the landscape image was taken, etc., which are included in the photography condition information.

[0067] Thus, if Figure 9As shown, an image of an evening landscape is displayed on the display surface 18 of the image display device 8. Furthermore, from the perspective of a user located in the indoor space 16, light of low illumination and low color temperature from the lower right light source 46, which simulates the setting sun at dusk, shines into the indoor space 16 from the upper right side of the window frame 28 through the opening 38 of the window frame 28. At this time, part of the light from the lower right light source 46 is reflected by the vertical frame 30d on the right side of the frame 30 (see FIG. 2 ). Figure 4 ) is blocked, so that the shadow 72 of the vertical frame 30d on the right side of the sash 30 is formed at the other end portion in the longitudinal direction of the inner peripheral surface of the horizontal frame 28b on the lower side of the window frame 28. In addition, a shadow is also formed on the inner wall portion 22 of the indoor space 16. Figure 9 As a result, it is possible to reproduce a state where the setting sun at dusk shines into the indoor space 16 from the west (positive side of the X axis) through the opening 38 of the window frame 28, thereby enhancing the sense of presence.

[0068] [4. Effect]

[0069] As described above, in this embodiment, the simulated window unit 2 is provided on the wall 20 of the indoor space 16. The simulated window unit 2 includes: a window frame 28 provided on the wall 20 and having an opening 38; an image display device 8 disposed so as to face the opening 38 of the window frame 28 and displaying a landscape image to the indoor space 16 through the opening 38 of the window frame 28; a light source 36 disposed between the window frame 28 and the image display device 8 and emitting light simulating sunlight, which is then directed toward the indoor space 16 through the opening 38 of the window frame 28; and a light shielding member (sash 30) that partially shields the light from the light source 36.

[0070] As described above, a portion of the sunlight-simulating light from the light source 36 is blocked by the light-blocking member, so that, for example, shadows 68, 70, and 72 of the light-blocking member are formed on the window frame 28. As a result, a state as if sunlight were entering the interior space 16 through the opening 38 of the window frame 28 can be reproduced, thereby enhancing the sense of presence.

[0071] In this embodiment, the simulated window unit 2 further includes a light-transmitting window panel 32 disposed to cover an opening 38 of the window frame 28, and a sash 30 functioning as a light-shielding member. The sash 30 extends radially inward from the window frame 28 and supports the outer periphery of the window panel 32. A light source 36 is disposed along the window frame 28.

[0072] As described above, a portion of the sunlight-simulating light from the light source 36 is blocked by the sash 30 , so that, for example, shadows 68 , 70 , and 72 of the sash 30 are formed on the window frame 28 .

[0073] In this embodiment, the window frame 28 is formed by upper and lower horizontal frames 30a and 30b and left and right vertical frames 30c and 30d arranged in a rectangular shape. The light source 36 includes an upper left light source 40, an upper right light source 42, a lower left light source 44, and a lower right light source 46. The upper left light source 40 and the upper right light source 42 are arranged along the upper horizontal frame 28a of the window frame 28, the lower left light source 44 is arranged along the left vertical frame 28c of the window frame 28, and the lower right light source 46 is arranged along the right vertical frame 28d of the window frame 28.

[0074] By lighting at least one of the upper left light source 40, the upper right light source 42, the lower left light source 44 and the lower right light source 46, it is possible to reproduce a state where sunlight from any direction enters the indoor space 16 through the opening 38 of the window frame 28, thereby further enhancing the sense of presence.

[0075] In this embodiment, the simulated window unit 2 further includes a rectangular support frame 34 disposed between the window frame 28 and the image display device 8 along the circumference of the window frame 28. The support frame 34 supports the upper left light source 40, the upper right light source 42, the lower left light source 44, and the lower right light source 46.

[0076] As described above, the upper left light source 40 , the upper right light source 42 , the lower left light source 44 , and the lower right light source 46 can be stably supported by the support frame 34 .

[0077] In addition, in this embodiment, the simulation window unit 2 also includes: an acquisition unit 64 for acquiring photographic condition information related to the photographic conditions of the landscape image; and a control unit 66 for controlling the lighting and extinguishing of each of the upper left light source 40, the upper right light source 42, the lower left light source 44 and the lower right light source 46 according to the photographic condition information.

[0078] By the above, for example, the lighting of the upper left light source 40, the upper right light source 42, the lower left light source 44 and the lower right light source 46 can be controlled corresponding to the date, time and weather when the landscape image is taken, so that the direction of the light entering the indoor space 16 through the opening 38 of the window frame 28 can be matched with the direction of the sunlight in the landscape image, which can further enhance the sense of presence.

[0079] In this embodiment, the control unit 66 further controls at least one of the illuminance and color temperature of light from each of the upper left light source 40 , the upper right light source 42 , the lower left light source 44 , and the lower right light source 46 based on the imaging condition information.

[0080] By the above, at least one of the illuminance and color temperature of each of the upper left light source 40, the upper right light source 42, the lower left light source 44 and the lower right light source 46 can be controlled corresponding to the date, time and weather when the landscape image is taken, so that the illuminance or color temperature of the light entering the indoor space 16 through the opening 38 of the window frame 28 can be matched with the illuminance or color temperature of the sunlight in the landscape image, respectively, which can further enhance the sense of presence.

[0081] Furthermore, in this embodiment, a simulated window 10 is provided on a wall 20 of an indoor space 16 and is used to reflect a landscape image displayed on an image display device 8. Simulated window 10 includes a window frame 28 disposed on wall 20 and having an opening 38 disposed so as to face image display device 8; a light source 36 disposed between window frame 28 and image display device 8 and emitting light that simulates sunlight, which is then directed toward indoor space 16 through the opening of window frame 28; and a light shielding member (sash 30) that partially shields light from light source 36.

[0082] As described above, it is possible to reproduce a state in which sunlight enters the indoor space 16 through the opening 38 of the window frame 28 , thereby enhancing the sense of presence.

[0083] (Other embodiments)

[0084] As described above, the embodiments are described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can also be applied to embodiments that are appropriately changed, replaced, added, omitted, etc. In addition, the various components described in the embodiments can be combined to form new embodiments.

[0085] Therefore, other embodiments are exemplified below.

[0086] In the above embodiment, the acquisition unit 64 acquires the scenic image from the camera 4. However, this is not limiting. For example, the scenic image from the camera may be stored on a server located outside the building 12, and the scenic image may be streamed from the server to the acquisition unit 64. In this case, the server may store the scenic image along with the camera's photographic condition information. Alternatively, a pre-captured scenic image (recorded video) may be stored on the server. The scenic image streamed from the server is then displayed on the image display device 8. In this case, the control unit 66 may control the illumination and color temperature of the light from the light source 36 based on the photographic condition information acquired from the server.

[0087] In the above embodiment, the scenic image from camera 4 is output to image display device 8 via controller 6. However, this is not limiting. Camera 4 may be omitted, and image display device 8 may be electrically connected to a playback device. In this case, the playback device plays back a recording medium storing the scenic image, and acquisition unit 64 obtains the scenic image and photographic condition information from the playback device. The scenic image (recorded image) reproduced by the playback device is then displayed on image display device 8. In this case, control unit 66 may also control the illumination and color temperature of the light from light source 36 based on the photographic condition information obtained from the playback device.

[0088] In the above embodiment, the light shielding member is formed by the grid 30 , but the present invention is not limited thereto and may be formed by, for example, an air guide plate or a reflector plate disposed in front of the light source 36 .

[0089] In the above embodiment, the LEDs 50 and 54 are arranged so that the optical axes of the LEDs 50 and 54 of the upper left light source 40 and the upper right light source 42 are oriented in the vertical direction (Z-axis direction). However, the present invention is not limited thereto. The LEDs 50 and 54 of the upper left light source 40 and the upper right light source 42 may be arranged obliquely so that the optical axes of the LEDs 50 and 54 of the upper right light source 42 are inclined relative to the vertical direction toward the indoor space 16. Alternatively, the LEDs 50 and 54 may be arranged so that the optical axes of the LEDs 50 and 54 of the upper left light source 40 and the upper right light source 42 are inclined relative to the vertical direction toward the indoor space 16.

[0090] Similarly, in the above embodiment, the LEDs 58 and 62 are arranged so that their optical axes are oriented in the left-right direction (X-axis direction). However, the present invention is not limited thereto. The LEDs 58 and 62 of the lower left light source 44 and the lower right light source 46 may be arranged so that their optical axes are tilted toward the indoor space 16 relative to the left-right direction. Alternatively, the LEDs 58 and 62 may be arranged so that their directivity is tilted toward the indoor space 16 relative to the left-right direction.

[0091] In the above embodiment, a single set of simulated windows 10 and image display devices 8 is disposed on the wall 20 of the indoor space 16. However, the present invention is not limited thereto and multiple sets of simulated windows 10 and image display devices 8 may be disposed. In this case, the multiple sets of simulated windows 10 and image display devices 8 are controlled by, for example, a single controller 6.

[0092] In the above embodiment, the image display device 8 is arranged in the landscape orientation with the display surface 18 in the horizontal direction. However, the present invention is not limited thereto and the image display device 8 may be arranged in the portrait orientation with the display surface 18 in the vertical direction.

[0093] In the above-described embodiment, the landscape image is a video (moving image), but the present invention is not limited thereto and may be a still image.

[0094] In the above embodiment, acquisition unit 64 obtains, as photographic condition information from camera 4, a) the date the scenic image was captured, b) the time the scenic image was captured, and c) the weather at the location where the scenic image was captured. However, this is not limiting and may also include, for example, d) the aperture of the camera (a camera used for capturing still images) at the time the scenic image was captured, e) the shutter speed of the camera at the time the scenic image was captured, and f) the ISO sensitivity of the camera at the time the scenic image was captured. In this case, control unit 66 can calculate the brightness of the location where the scenic image was captured based on the aperture, shutter speed, and ISO sensitivity information from acquisition unit 64. Based on the calculated brightness, control unit 66 can control the illumination intensity of each of upper left light source 40, upper right light source 42, lower left light source 44, and lower right light source 46.

[0095] In the above embodiment, the light source 36 is divided into four light sources (upper left light source 40, upper right light source 42, lower left light source 44, and lower right light source 46). However, this is not limiting, and the arrangement and number of divisions of the light source 36 can be arbitrarily set. For example, by increasing the number of divisions of the light source 36, more realistic shadow reproduction can be achieved.

[0096] Alternatively, the acquisition unit 64 may acquire information related to the location where the landscape image was captured (e.g., longitude and latitude) as the photographic condition information from the camera 4. Thus, the control unit 66 can control the turning on and off of each of the upper left light source 40, the upper right light source 42, the lower left light source 44, and the lower right light source 46 in accordance with the location where the landscape image was captured.

[0097] As described above, the embodiments are described as examples of the technology disclosed herein, and the accompanying drawings and detailed description are provided for this purpose.

[0098] Therefore, the components described in the drawings and detailed description include not only those components essential for solving the problems but also components that are not essential for solving the problems in order to illustrate the technology. Therefore, just because non-essential components are described in the drawings and detailed description, it cannot be automatically determined that they are essential components.

[0099] Furthermore, the above-described embodiments are provided to illustrate the technology of the present disclosure, and therefore various changes, substitutions, additions, omissions, etc. can be made within the scope of the technical claims or their equivalents.
