[0122] If the user interface device (200) does not include a processor (270), the user interface device (200) may be operated under the control of a processor or control unit (170) of another device in the vehicle (100).

[0123] Meanwhile, the user interface device (200) can be named as a vehicle display device.

[0124] The user interface device (200) can be operated under the control of the control unit (170).

[0125] The object detection device (300) is a device for detecting an object located outside the vehicle (100).

[0126] The objects may be various objects related to the operation of the vehicle (100).

[0127] Meanwhile, a vehicle imaging device according to the present specification is described. In this regard, a vehicle display showing various driving information of a vehicle is located below the driver's forward driving field of vision, and this affects driving safety (rubber necking). Therefore, a vehicle imaging device that ensures driving safety by projecting images onto the windshield at the front of the vehicle, close to the driver's field of vision, such as a recent HUD (Head-up Display), can be installed in a vehicle.

[0128] In addition, an infotainment device for providing personal information and personal entertainment content needs to be implemented in the passenger seat or rear seat of the vehicle. Therefore, a vehicle video device needs to be provided to display driving-related information in the area in front of the driver's seat or to provide personal entertainment content in the area in front of the passenger seat or rear seat.

[0129] In order for such driving-related information or entertainment content to be displayed on a specific area of ​​the windshield in front of the vehicle, it is necessary to configure it with a large aspect ratio in which the width in one axis is greater than the length in the other axis by a certain proportion. There is a problem in that there is no specific specification regarding where in the vehicle and in what structure a vehicle video device can be provided to configure a screen with such a large aspect ratio.

[0130] To solve these problems, the present specification aims to provide a vehicle imaging device having a large aspect ratio using a projection optical system associated with a vehicle. Additionally, the present specification aims to display driving-related information on a screen having a large aspect ratio in a specific area of ​​the windshield in front of the vehicle. Furthermore, the present specification aims to provide a vehicle imaging device having an optical structure and a special screen to enable an image to have a large aspect ratio using a single image module. Additionally, the present specification aims to implement continuous images associated with driving-related information using a single image module to enable the image to have a large aspect ratio. Furthermore, the present specification aims to provide a vehicle imaging device with a small and thin volume.

[0131] A vehicle imaging device for achieving the aforementioned purpose will be described in detail with reference to the drawings. In this regard, FIG. 6a shows a configuration in which a screen of a predetermined ratio is formed on a specific area of ​​the front windshield of a vehicle. FIG. 6b shows a structure in which a vehicle imaging device for implementing the screen of the predetermined ratio of FIG. 6a is placed inside the dashboard of a vehicle.

[0132] Referring to FIG. 6a, an image having a width (Wa) in one axis direction and a length (La) in the other axis direction may be displayed in a specific area (251R) of the vehicle's windshield. The image may be configured to include a plurality of image areas in which information necessary for driving the vehicle is displayed. The plurality of image areas may include a first image area (IR1) to a third image area (IR3). A first image containing vehicle-related information may be displayed in the first image area (IR1), which is closest to the driver's field of vision. A second image related to the driving route of the vehicle may be displayed in the second image area (IR2). A third image related to a map including a starting point and a destination may be displayed in the third image area (IR3). As the plurality of images are displayed in the specific area (251R), the width (Wa) in one axis direction may be set to a predetermined ratio, for example, five times or more, than the length (La) in the other axis direction.

[0133] Referring to FIGS. 6a and 6b, a vehicle imaging device (1000) may be placed inside the dashboard of a vehicle. The vehicle imaging device (1000) may be placed in a specific area inside the dashboard so as not to overlap with the area where the steering wheel and pedals are placed. An image formed by light reflected from a screen panel (1200) constituting the vehicle imaging device (1000) may be displayed on a specific area (251R) of the vehicle's windshield. The specific area (251R) may be implemented with a predetermined length (La) so that the image is displayed within the driver's field of vision. The distance from the center of the driver's gaze to the center of the specific area (251R) may be implemented with a predetermined distance (Da).

[0134] Hereinafter, an image display device according to the present specification is described. The purpose of the present specification is to provide an image display device for vehicles or an image display device for advertising that displays a pop-up image together with a background image. Furthermore, the purpose of the present specification is to implement an image display device capable of maintaining image quality and viewing angle characteristics above a certain level while reducing the volume of the optical system.

[0180] Further volume reduction is possible as an aperture lens (1300a) is positioned on the front of the imaging device (1000). For example, to produce a floating image of 60mm x 60mm, the volume of the imaging device (1000) of FIG. 10(b) can be implemented as 1.48L. Meanwhile, to produce a floating image of 60mm x 60mm, the volume of the imaging device (1000) equipped with the aperture lens (1300a) of FIG. 9 and FIG. 11 can be reduced to 1.12L.

[0181] Referring to FIGS. 7 to 11, an image display device (1000) according to the present specification may be configured to include a display (1100), a pop-up image generating device (1200), and a polarizing mirror (1240, 1300, 1300a).

[0182] The display (1100, 1110b) may be configured to generate and display a background image (BI). A pop-up image generating device (1200) may be placed in the lower structure of the lower area of ​​the display (1100, 1110b). The pop-up image generating device (1200) may be configured to generate a pop-up image (PUI) that is displayed floating in a forward direction relative to the background image (BI).

[0183] A polarizing mirror (1240, 1300, 1300a) may be placed in front of a background image (BI) generated from a display (1110, 1110b). A polarizing mirror (1240, 1300, 1300a) may be placed spaced apart from the display (1110, 1110b) that generates the background image (BI). A polarizing mirror (1240, 1300, 1300a) may be placed in front of the display (1110). A polarizing mirror (1240, 1300, 1300a) may be placed in front of the display (1110) where the background image (BI) is generated, so as to have an inclination angle. The polarizing mirror (1240, 1300, 1300a) may be placed in the front direction, which is the positive Z-axis direction relative to the display (1110) where the background image (BI) is displayed.

[0184] The polarizing mirror (1240, 1300, 1300a) can be positioned at an angle of inclination in the Z-axis direction relative to the Y-axis. Accordingly, the light signal of the background image (BI) reflected from the side of the pop-up image generating device (1200) of the lower structure can be displayed at an optimal position when reflected or transmitted from the polarizing mirror (1240, 1300, 1300a).

[0185] The polarizing mirror (1240, 1300, 1300a) may be configured to reflect or transmit the pop-up image (PUI). The background image (BI) may be displayed as a virtual image using the polarizing mirror (1240, 1300, 1300a). The pop-up image (PUI) may be displayed spaced apart from the front of the background image (BI) by light signals reflected by at least one reflecting mirror (1220, 1230; 1220f, 1230f; 1220b, 1230b; 1230c) of the substructure. The pop-up image (PUI) can be displayed as a real image on the front of the background image (BI) by light signals reflected by at least one reflective mirror (1220, 1230; 1220f, 1230f; 1220b, 1230b; 1230c) of the substructure.

[0186] Meanwhile, the image display device according to the present specification may be configured to display a pop-up image (floating image) at a predetermined distance on the Z-axis in response to the detection of an event. In this regard, FIG. 12 shows an example of a screen in which a pop-up image is displayed at a predetermined distance on the Z-axis in response to the detection of an event.

[0187] Referring to FIGS. 5 through 12, in response to the detection of a first event by the control unit (170), the pop-up image generating device (1200) can generate a first pop-up image and display it on the background image at a distance of a first distance. The first event may be associated with a low battery, oil warning, low air pressure, low fuel, seatbelt not fastened, high beams turned on, brake pad warning, ignition switch warning, steering lock, door open, trunk open.

[0188] In response to the detection of a second event by the control unit (170) during vehicle operation, the pop-up image generating device (1200) can generate a second pop-up image (PUI2) and display it on the background image at a distance of a second distance. The second event may be associated with entering a school zone, approaching an emergency rescue vehicle, entering a black ice section, recommending vehicle ventilation, or a tire puncture.

[0189] Meanwhile, regarding the second event, as the distance to the school zone, the distance to the emergency rescue vehicle, and the distance to the black ice section become closer, the control unit (170) can detect the speed of the vehicle and the proximity distance. If it is determined that the vehicle needs to decelerate based on the speed and proximity distance, the popup image generating device (1200) can control the size of the second popup image (PUI2) and the second distance to increase. For example, if it is determined that the vehicle needs to decelerate based on the speed and proximity distance, the popup image generating device (1200) can control the size of the second popup image (PUI2) containing "STOP" to increase. Additionally, the popup image generating device (1200) can control the second distance from the background image (BI) where the second popup image (PUI2) containing "STOP" is floated to increase.

[0190] Meanwhile, the pop-up visual interface (PUI) is not limited to the detection of the first and second events but can be modified depending on the application. The pop-up visual interface can be implemented with various customized images, such as a compass, clock, or stopwatch, based on personal preference. In particular, by analyzing a large amount of information obtained from various internal and external communications, sensors, cameras, LiDAR, and radar, the system can provide pop-up visuals in the event of an emergency. The analyzed information may be related to vehicle diagnostic data, traffic information, navigation data, and autonomous driving data. Therefore, this information can be immediately conveyed to the driver via the pop-up visual interface to assist in safe driving.

[0191] Meanwhile, the pop-up image generating device (1200) of the image display device according to the present specification may be configured to display a panoramic image. In this regard, the vehicle may be configured to display a front panoramic view by mounting a display on the lower area of ​​the windshield. This has the advantage of contributing to safe driving because the driver's field of vision is directed forward while driving, and the driver can view various vehicle and infotainment information. However, there is an issue in that the display device partially obscures the lower area of ​​the windshield, thereby reducing the area where the front can be viewed.

[0192] A floating image can be formed in the upper area of ​​the device by combining the positions of the object, mirror, and lens of the pop-up image generating device (1200). Accordingly, by arranging multiple pop-up generating devices so that the floating image continues in the lower area of ​​the vehicle's windshield, a panoramic floating image can be realized. Thus, a panoramic view system in which a panoramic image is displayed in the lower area of ​​the vehicle's windshield can be realized.

[0193] In this regard, FIG. 13 illustrates the structure of an image display device configured to display a panoramic image. Referring to FIG. 13, the image display device (1000) may be a vehicle image display device placed inside the windshield (250) of a vehicle, but is not limited thereto. The image display device (1000) of FIG. 13 may be implemented as an information image display device that displays information. For example, the image display device (1000) of FIG. 13 may be implemented as an outdoor advertising display device that displays advertisements.

[0194] Referring to FIG. 13, an image display device (1000) equipped with a pop-up image generating device (1200) may be disposed inside the dashboard (1001) of a vehicle. The pop-up image generating device (1200) may include a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) to display a plurality of pop-up images (PUI-1 to PUI-N). The number of the plurality of pop-up images (PUI-1 to PUI-N) is not limited to five and can be changed depending on the application.

[0195] Each of the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) may be formed with the same structure. Each of the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) may be configured to include an object (1210b), a first reflective mirror (1220b), and a second reflective mirror (1230b). Optical signals emitted from the object (1210b) may be reflected by the first reflective mirror (1220b) and the second reflective mirror (1230b), pass through a polarizing mirror, and be displayed as a plurality of pop-up images (PUI-1 to PUI-N).

[0196] Each display area of ​​a plurality of pop-up images (PUI-1 to PUI-N) can be formed spaced apart from one another. Accordingly, fitting lines (FL) can be formed between each display area of ​​the plurality of pop-up images (PUI-1 to PUI-N). As a result, a discontinuous panoramic view is provided instead of a continuous panoramic view.

[0197] FIG. 14 shows the structure of a video display device in which fitting lines exist between multiple pop-up images of FIG. 13. Referring to FIG. 13 and FIG. 14, the video display device (1000) can be used for advertising signs, etc., in addition to a vehicle. The upper surface (US) of the pop-up video display device (1200) can form the dashboard (1001) of a vehicle or form the lower structure (1002) of an advertising sign.

[0198] The pop-up image generating device (1200) may include a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) spaced apart in the X-axis direction to display a plurality of pop-up images (PUI-1 to PUI-N) in the X-axis direction. The polarizing mirror (1300) may be implemented with a length greater than a predetermined length in the X-axis direction so that a plurality of pop-up images (PUI-1 to PUI-N) generated by the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) are displayed.

[0199] The number of multiple pop-up images (PUI-1 to PUI-N) is not limited to five and can be changed depending on the application. Fitting lines (FL) are formed between the respective display areas of the multiple pop-up images (PUI-1 to PUI-N) so that the multiple pop-up images (PUI-1 to PUI-N) can be distinguished.

[0200] A pop-up image generating device (1200) may be implemented in the lower structure (1002) of the image display device (1000). A display structure may be formed in the upper structure (1003) of the image display device (1000). When the image display device (1000) is installed in a vehicle, a windshield (250) having a transparent display in the upper structure (1003) may be installed. When the image display device (1000) is installed in an outdoor billboard, a display may be formed in the upper structure (1003). The transparent display in the upper structure (1003) may be a curved display, but is not limited thereto, and a display of various shapes may be formed.

[0201] Referring to FIGS. 8, 13 and 14, the pop-up image generating device (1200) may be configured to include a plurality of pop-up image generating devices. Each of the pop-up image generating devices (1200) may be configured to include an object (1210b), a first reflective mirror (1220b), and a second reflective mirror (1230b).

[0202] Unlike a front panoramic display installed at the bottom of the vehicle's windshield (250) to cover the bottom of the windshield (250), a pop-up image can be displayed in the upper area of ​​the dashboard (1001). Therefore, a design is possible without any separate protrusions or depressions on the vehicle's dashboard. Additionally, there is an advantage that the driver's gaze can pass through the floating image and observe the front area of ​​the windshield in all situations where the pop-up image is displayed or not.

[0203] Meanwhile, each of the plurality of pop-up image generating devices of the image display device according to the present specification is not limited to the optical structure of FIG. 8 but may be implemented as one of the optical structures of FIG. 7 to FIG. 10. In this regard, FIG. 15 shows the configuration of an image display device having a plurality of pop-up image generating devices implemented with the optical structure of FIG. 9. FIG. 16 shows a plurality of pop-up images and an eyebox area implemented by the image display device of FIG. 15.

[0204] Referring to FIGS. 9, 15, and 16, the pop-up image generating device (1200) may include a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) to display a plurality of pop-up images (PUI-1 to PUI-N). The number of the plurality of pop-up images (PUI-1 to PUI-N) is not limited to 5 and can be changed according to the application.

[0205] Each of the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) may be formed with the same structure. Each of the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) may be configured to include an object (1210c), a first optical lens (1220c), and a reflective mirror (1230c). Optical signals emitted from the object (1210c) may pass through the first optical lens (1220c), be reflected by the reflective mirror (1230c), and pass through the polarizing mirror (1300) to be displayed as a plurality of pop-up images (PUI-1 to PUI-N).

[0206] The first optical lens (1220c) can be implemented as a doublet lens comprising a first lens (1221c) having a first curvature and a second lens (1222c) having a second curvature. The reflective mirror (1230c) can be implemented as a folding mirror structure.

[0207] The object (1210c) may be configured to include a first object (1211) and a second object (1212). The first object (1211) may be configured to emit a first optical signal. The first object (1212) may be positioned adjacent to the first object (1211) in the X-axis direction and configured to emit a second optical signal. The first pop-up image generating device (1200-1) may be configured to include a first object (1210c), a doublet lens (1220c), a reflective mirror (1230c), and a polarizing mirror (1300). The second pop-up image generating device (1200-1) may be configured to include a second object (1210c), a doublet lens (1220c), a reflective mirror (1230c), and a polarizing mirror (1300).

[0208] The polarizing mirror (1300) may be implemented as an aperture lens (1300a) or a second optical lens (1240). The polarizing mirror (1300) may be composed of a second optical lens (1240) that transmits a light signal reflected from a reflective mirror (1230c). The second optical lens (1240) may be configured to transmit a light signal reflected from a reflective mirror (1230c). The reflective mirror (1230c) of the first pop-up image generating device (1200-1) and the reflective mirror (1230c) of the second pop-up image generating device (1200-2) may be positioned with a portion of their regions separated on the X-axis.

[0209] Each of the plurality of eyebox areas (EB1 to EBN) formed by each of the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) may be spaced apart along the X-axis. Accordingly, the length of the plurality of eyebox areas (EB1 to EBN) along the X-axis may be formed to be longer than five times the width along the Y-axis. The width of the plurality of eyebox areas (EB1 to EBN) along the Y-axis may be formed to be approximately 74 mm. The length of the plurality of eyebox areas (EB1 to EBN) along the X-axis may be formed to be approximately 390 mm. Each of the plurality of eyebox areas (EB1 to EBN) may be formed in a square structure. The spacing between the plurality of eyebox areas (EB1 to EBN) may be formed to be approximately 5 mm, corresponding to (390-74*5) / 4.

[0210] Each display area of ​​a plurality of pop-up images (PUI-1 to PUI-N) can be formed spaced apart from one another. Accordingly, fitting lines (FL) can be formed between each display area of ​​the plurality of pop-up images (PUI-1 to PUI-N). As a result, a discontinuous panoramic view is provided instead of a continuous panoramic view.

[0211] A structure in which multiple pop-up video devices are arranged in a line results in fitting lines existing at the boundary surfaces between the devices. Consequently, fitting lines exist between multiple floating images, making it difficult to provide continuous panoramic images. In this regard, FIG. 17 illustrates the structure of an image display device configured to provide continuous panoramic images. FIG. 18 illustrates the structure of the first and second pop-up video generating devices of FIG. 17.

[0212] Referring to FIG. 17, the pop-up image generating device (1200) may include a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) spaced apart in the X-axis direction to display a panoramic image between the bottom of the windshield and the dashboard. The polarizing mirror (1300) may be implemented with a length greater than a predetermined length in the X-axis direction so that a plurality of pop-up images generated by the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) are displayed.

[0213] FIG. 18(a) shows a first pop-up image generating device (1200-1) that transmits a first optical signal of vertical polarization (first polarization) through a polarizing mirror (1300). Referring to FIG. 18(a), the first pop-up image generating device (1200-1) may be configured to include a first object (1211), a first reflective mirror (1220a), a second reflective mirror (1230a), and a polarizing mirror (1300). To reduce the volume of the system relative to the size of the pop-up image (PUI-1), the polarizing mirror (1300) may be replaced with an aperture lens (1300a).

[0214] FIG. 18(b) shows a second pop-up image generating device (1200-2) that reflects a second optical signal of horizontal polarization (second polarization) through a polarizing mirror (1300). The second pop-up image generating device (1200-2) may be positioned adjacent to the first pop-up image generating device (1200-1) on the X-axis. Referring to FIG. 18(b), the second pop-up image generating device (1200-2) may be configured to include a second object (1212), a first reflective mirror (1220b), a second reflective mirror (1230b), and a polarizing mirror (1300). To reduce the volume of the system relative to the size of the pop-up image (PUI-2), the polarizing mirror (1300) may be replaced with an aperture lens (1300a).

[0215] Referring to FIG. 18, a polarizing mirror (1300) can be placed between the second reflecting mirror (1230a, 1230b) and the pop-up image (PUI-1, PUI-2). When polarization orthogonal to the first and second objects (1211, 1212) that generate the pop-up image (PUI-1, PUI-2) is applied, the pop-up image (PUI-1, PUI-2) is reflected or transmitted from the polarizing mirror (1300) depending on the state of polarization.

[0216] An object (1210) emitting an optical signal may be configured to include a first object (1211) and a second object (1212). The first object (1211) may be configured to emit a first optical signal of vertical polarization (first polarization). The second object (1212) may be positioned adjacent to the first object (1211) in the X-axis direction. The second object (1212) may be configured to emit a second optical signal of horizontal polarization (second polarization) that is orthogonal to the polarization of the first object (1211).

[0217] The first optical signal of vertical polarization can be reflected by the polarizing mirror (1300) and displayed as a first floating image spaced a first distance in the front direction from the polarizing mirror (1300). The second optical signal of horizontal polarization can pass through the polarizing mirror (1300) and be displayed as a second floating image spaced a first distance in the front direction from the polarizing mirror (1300).

[0218] The positions of the second reflective mirrors may be alternately arranged between adjacent devices among a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N). The first pop-up image generating device (1200-1) may be configured to include a first object (1211), a first reflective mirror (1220a), and a second reflective mirror (1230a). The second pop-up image generating device (1200-2) may be configured to include a second object (1212), a first reflective mirror (1220b), and a second reflective mirror (1230b).

[0219] Popup image generating devices (1200-1, 1200-2, ..., 1200-N) may have the vertical polarization structure of FIG. 18(a) and the horizontal polarization structure of FIG. 18(b) alternately arranged. Meanwhile, the distance between adjacent first and second popup image generating devices (1200-1, 1200-2) may be closer than the distance between the first and second popup image generating devices of FIG. 13 to 15. Accordingly, the image display device (1000) of FIG. 17 and FIG. 18 can provide a continuous panoramic view without fitting lines.

[0220] In this regard, the first pop-up image generating device (1200-1) is not limited to the vertical polarization structure of FIG. 18(a). The second pop-up image generating device (1200-2) is not limited to the horizontal polarization structure of FIG. 18(b). As another example, the first pop-up image generating device (1200-1) may be configured to include a second object (1212), a first reflective mirror (1220b), and a second reflective mirror (1230b). The second pop-up image generating device (1200-2) may be configured to include a first object (1211), a first reflective mirror (1220a), and a second reflective mirror (1230a).

[0221] Meanwhile, the second reflective mirror (1230a) of the first pop-up image generating device (1200-1) may be positioned in the rear direction along the Z-axis relative to the polarizing mirror (1300) inside the dashboard. The second reflective mirror (1230b) of the second pop-up image generating device (1200-1) may be positioned protruding in the front direction along the Z-axis relative to the polarizing mirror (1300) inside the dashboard.

[0222] The first object (1211) of the first pop-up image generating device (1200-1) may be positioned at an angle of inclination less than 90 degrees with respect to the horizontal plane. The second object (1212) of the second pop-up image generating device (1200-2) may be positioned at an angle of inclination greater than 90 degrees with respect to the horizontal plane. The second pop-up image generating device (1200-2) may be positioned adjacent to the first pop-up image generating device (1200-1).

[0223] A first object (1211) and a second object (1212) implemented with different inclination angles may be spaced apart at a predetermined distance on the X-axis. The first object (1211) and the second object (1212) implemented with different inclination angles may be configured to emit optical signals of different polarizations that are orthogonal.

[0224] As described above, the pop-up image generating device (1200) may include a plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) spaced apart in the X-axis direction to display a panoramic image between the bottom of the windshield and the dashboard. The polarizing mirror (1300) may be implemented with a length greater than a predetermined length in the X-axis direction so that a plurality of pop-up images generated by the plurality of pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) are displayed.

[0225] Meanwhile, the first reflective mirror (1220a) of the first pop-up image generating device (1200-1) and the first reflective mirror (1220b) of the second pop-up image generating device (1200-2) can be arranged horizontally on a horizontal plane inside the dashboard. Accordingly, the first reflective mirror (1220a) of the first pop-up image generating device (1200-1) and the first reflective mirror (1220b) of the second pop-up image generating device (1200-2) can be implemented as a single reflective mirror (1220).

[0226] FIG. 19 is a view of the second reflective mirrors of the image display device of FIG. 17 and FIG. 18 in the XY plane. Referring to FIG. 17 through FIG. 19, the second reflective mirror (1230a) of the first pop-up image generating device (1200-1) may be positioned in the rearward direction relative to the polarizing mirror (1300) on the Z-axis. The second reflective mirror (1230b) of the second pop-up image generating device (1200-2) may be positioned protruding in the frontward direction relative to the polarizing mirror (1300) on the Z-axis. The second reflective mirror (1230b), indicated by a solid line, may be positioned protruding in the frontward direction relative to the second reflective mirror (1230a), indicated by a dotted line, on the Z-axis.

[0227] The second reflective mirror (1230a) of the first pop-up image generating device (1200-1) and the second reflective mirror (1230b) of the second pop-up image generating device (1200-2) may be arranged with some areas overlapping on the X-axis. In this regard, the second reflective mirror (1230a) of the first pop-up image generating device (1200-1) and the second reflective mirror (1230b) of the second pop-up image generating device (1200-2) may be arranged with an overlap length (OLx) on the X-axis.

[0228] Accordingly, it is possible to provide a continuous panoramic view without fitting lines between multiple pop-up images (PUI-1 to PUI-N). In this regard, multiple pop-up images (PUI-1 to PUI-N) can be displayed as a continuous view through multiple pop-up image generating devices (1200-1, 1200-2, ..., 1200-N). Each of the multiple eyebox regions (EB1 to EBN) formed by the multiple pop-up image generating devices (1200-1, 1200-2, ..., 1200-N) can be arranged so that they overlap or have matching boundaries without being separated on the X-axis.

[0229] The image display device according to the present specification has been described above. The technical effects of the image display device according to the present specification may be summarized as follows, but are not limited thereto.

[0230] According to the present specification, a vehicle image display device or an advertising image display device that displays a pop-up image together with a background image can be provided.

[0232] According to the present specification, an image display device can be implemented that enhances the user's immersion while focusing on a pop-up image, while eliminating dizziness or discomfort while driving. In this regard, by controlling the image formation position of the pop-up image through an optimal optical design using reflection or transmission methods and enabling a design that reduces binocular parallax, a clear and non-dizziness floating image can be generated.

[0233] According to the present specification, an image display device capable of producing a clear image with high brightness and rich three-dimensionality at a low cost without using expensive optical materials or components can be implemented. In this regard, a reflection or transmission type image display device can be implemented using at least one reflective mirror and a polarizing mirror without utilizing a dihedral corner reflector array or a micro-lenslet array.

[0236] The foregoing invention may be implemented as computer-readable code on a medium on which a program is recorded. A computer-readable medium includes all types of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SSD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. Additionally, the computer may include a processor or a control unit.
