FIG. 8A is a view illustrating an appearance of a head-up display device according to an embodiment of the present invention, and FIG. 8B is a conceptual diagram referred to explain a head-up display according to an embodiment of the present invention.

Referring to the drawings, the head-up display apparatus 1000 can be disposed inside the vehicle 100, and can provide the generated information to a user.

The head-up display device 1000 may be disposed inside the cockpit module. The head-up display apparatus 1000 may include a cover 1001 that can be opened or closed according to user input.

The head-up display apparatus 1000 can generate graphic objects based on the plurality of light sources 1052 and the image forming panel 1055. [ The generated graphic object can be displayed by projecting a windshield (ws). According to the embodiment, the head-up display apparatus 1000 further includes a combiner, and the graphic object can be projected and displayed on a combiner.

The head-up display apparatus 1000 may provide an augmented reality image.

The head-up display apparatus 1000 may include an image generating unit 1050, a first mirror 1002, and a second mirror 1003. [

The image generation unit 1050 is provided with a backlight unit 1051 and can project display light toward the windshield WS to realize an augmented reality image under the control of the processor 1070. [

The processor 1070 is functionally coupled to the indoor camera 220, the camera 310 and the image generation unit 1050 to provide a specific enhancement based on the images provided from the indoor camera 220 and / It is possible to generate image data for constituting a real image and provide it to the image generating unit 1050. [

In one embodiment, the processor 1070 detects a specific object OB existing in front of the vehicle 100 on the basis of the forward image provided from the camera 310, It is possible to provide the image generating unit 1050 with image data for constructing the augmented reality image.

The image generating unit 1050 can output the display light corresponding to the augmented reality image to the first mirror 1002 based on the image data provided from the processor 1070. [ The second mirror 1003 can reflect the display light reflected from the first mirror 1002 to the windshield WS so that the augmented reality image can be realized through the windshield WS. The size of the display light corresponding to the augmented reality image can be enlarged or the projection position with respect to the windshield WS can be adjusted by the optical path from the image generating unit 1050 to the windshield WS.

On the other hand, the display light reflected by the second mirror 1003 can be projected in a predetermined area (hereinafter, display area) of the windshield WS. A reflective film may be attached to the display area DR so that the augmented reality image ARI can be seen more clearly.

At this time, an augmented reality image is implemented by the display light projected on the windshield WS. In the driver's position, the augmented reality image ARI is displayed on the display area DR, not the display area DR of the windshield WS. May be seen to be displayed outside the vehicle 100 beyond. That is, the augmented reality image ARI can be perceived as a virtual image appearing to be floating in front of the vehicle 100 by a predetermined distance. For example, the augmented reality image (ARI) may be a graphical object that provides information about the contours, speed, collision alerts, etc. of the object OB.

When the head-up display apparatus 1000 implements the augmented reality image (ARI) through a virtual image, in order for the driver to recognize the augmented reality image ARI through the display area DR, EB). The eye box EB is a space of a vehicle 100 having a three-dimensional volume. When the driver's eye is located in the eye box EB, the eye box EB confirms the augmented reality image ARI through the display area DR. . On the other hand, when the driver's eye is out of the eye box EB, only a part of the augmented reality image ARI may be visible, or the augmented reality image ARI may not be visible at all. In the memory 640, coordinate values defining the boundaries of the eye box (EB) may be stored in advance.

On the other hand, when the driver's eye is located in the eye box EB, even if the driver can recognize the augmented reality image ARI, An error may occur between the actual image of the object OB recognized through the AR and the AR image. This is a phenomenon that occurs because the distance to the augmented reality image (ARI) differs from the distance to the object (OB) when the position of the driver is taken as a reference. As the object (OB) (ARI) can be gradually increased. In order to reduce or eliminate such an error, the processor 1070 may post-process the augmented reality image (ARI) based on the driver's eye position.

Specifically, the processor 1070 can detect the driver's eye position from the driver's image provided from the indoor camera 220. [ In one embodiment, the processor 1070 detects the eyes of the driver appearing in the driver's image using the eye tracking technique and calculates the three-dimensional coordinate values of the detected eyes. In another embodiment, the processor 1070 may use the edge detection technique to extract the driver's facial contour from the driver image and estimate the driver's eye position based on the extracted contour.

Information about the reference position can be preset in the memory 640, and the processor 1070 can calculate the direction and distance of the eye position with respect to the reference position by comparing the eye position of the driver with the reference position. That is, the processor 1070 can determine how far the driver's current eye position is from the reference position.

Processor 1070 may determine a visual effect to be applied to post-processing for the augmented reality image, depending on the direction and distance of the eye position relative to the reference position. In addition, processor 1070 may determine the magnitude of the determined visual effect.

The processor 1070 processes the augmented reality image ARI using the determined visual effect to suppress an error with the actual image of the object OB generated in accordance with the eye position change in the eye box EB , It is possible to provide the driver with more improved inter-image matching results.

The visual effects applicable to post-processing for the augmented reality image may include at least one of blurring, repositioning, resizing, shape modification, and skew modification for the augmented reality image. For example, when a horizontal error occurs between the augmented reality image and the actual image of the object as the driver's eye position changes left and right along the y axis, the processor 1070 horizontally moves the augmented reality image toward the actual image Or to compensate for discrepancies between the two images through a visual effect such as expansion of the augmented reality image, or blurring of at least a portion of the augmented reality image.

Each of the second group of cells 1101b may function as a lens.

The second area RG2 of the image forming panel 1055 can be determined by the second sub FEL 1110b.

Specifically, the width W2 and the height H2 of the second region RG2 can be determined by the second width cw2 and the second height ch2 of the second group of cells 1101b. For example, the width W2 of the second region RG2 is determined by multiplying the second width cw2 of the cell 1101b of the second group by the lateral magnification of the cell 1101b. The height H2 of the second region RG2 is determined by multiplying the second height ch2 of the second group of cells 1101b by the vertical magnification of the cell 1101b.

The third sub FEL 1110c may include a third group of cells 1101c. The size of the third group of cells 1101c may correspond to the size of the second area RG2. For example, the size of the third group of cells 1101c and the size of the second region RG2 can form a proportional relationship. The size of the third group of cells 1101c may be the same as the size of the second group of cells 1101b. The number of cells in the third group 1101c may be the same as the number of cells in the second group 1101b.

15A to 15C are diagrams for explaining an operation in which a screen of a head-up display device according to an embodiment of the present invention is implemented.

In the drawing, a plurality of light sources 1052 are exemplified as including a first light source 1052a, a second light source 1052b, and a third light source 1052c. In addition, the FEL 1110 is illustrated as including a first sub-FEL 1110a, a second sub-FEL 1110b, and a third sub-FEL 1110c.

15A is a diagram referred to explain the operation in which the first screen SN1 is implemented by the first light source 1052a and the first sub FEL 1110a according to an embodiment of the present invention. The head-up display device 100 of Fig. 15A is an operation for realizing a small screen as compared with Fig. 15B.

Referring to Fig. 15A, the processor 1070 can control to output light from the first light source 1052a based on received information, signals, and data. The processor 170 can control so that white light is output.

The light output from the first light source 1052a becomes parallel through the first collimation lens 910a. The light having passed through the first collimation lens 910a is incident on the first sub FEL 1110a.

The light incident on the first sub FEL 1110a passes through each of the group cells 1101a of the first sub FEL 1110a and is enlarged to a predetermined size corresponding to the first region RG1. The light incident on the first sub FEL 1110a is uniformly transmitted while passing through each of the group cells 1101a of the first sub FEL 1110a.

The light emitted from the first sub FEL 1110a is incident on the image forming panel 1055. In particular, the light emitted from the first sub FEL 1110a is incident on the first region RG1 of the image forming panel 1055. [

The processor 1070 can control the image forming panel 1055 so that the alignment state of the liquid crystal molecules disposed in the first region RG1 is adjusted. For example, the processor 1070 may implement display light for controlling the arrangement of liquid crystal molecules to generate an image on the outside.

The processor 1070 can control the image forming panel 1055 so that the arrangement state of the liquid crystal molecules disposed in other regions except for the first region RG1 is maintained.

The first area RG1 of the image forming panel 1055 may be an area corresponding to a part of the entire area. In this case, it becomes possible to provide light with a smaller output than when providing light toward the entire area. Therefore, when light is provided only to the first region RG1, efficiency becomes better than when light is provided to the entire region.

When a screen of the same brightness is realized, the screen can be realized with less energy consumption by providing light to the first area RG1 than when providing light to the entire area. In this case, less heat is generated in the light source, which is advantageous in terms of heat management.

15B shows a case where the second screen SN2 is displayed by the second light source 1052b, the second sub FEL 1110b, the third light source 1052c and the third sub FEL 1110c according to the embodiment of the present invention And is a diagram referred to for describing an operation to be implemented. The head-up display device 100 of FIG. 15B realizes a large screen as compared with FIG. 15A.

Referring to Fig. 15B, the processor 1070 can control to output light from the second light source 1052b and the third light source 1053c based on information, signals, and data received. According to the embodiment, the processor 1070 can control to output light from either the second light source 1052b or the third light source 1053c. The processor 1070 can control so that white light is output.

The light output from the second light source 1052b becomes parallel via the second collimation lens 910b. The light having passed through the second collimation lens 910b is incident on the second sub FEL 1110b.

The light incident on the second sub FEL 1110b passes through each of the group cells 1101a of the second sub FEL 1110b and is enlarged to a certain size corresponding to the second region RG2. Further, the light incident on the second sub FEL 1110b passes through each of the group cells 1101b of the second sub FEL 1110b, and becomes uniform.

The light emitted from the second sub FEL 1110b is incident on the image forming panel 1055. In particular, the light emitted from the second sub FEL 1110b is incident on the second region RG2 of the image forming panel 1055. [

The light output from the third light source 1052c is made parallel through the third collimation lens 910c. The light having passed through the third collimation lens 910c is incident on the third sub FEL 1110c.

The light incident on the third sub FEL 1110c passes through each of the group cells of the third sub FEL 1110c and is enlarged to a certain size corresponding to the second region RG2. Further, the light incident on the third sub FEL 1110c passes through each of the group cells of the third sub FEL 1110c, and becomes uniform.

The light emitted from the third sub FEL 1110c is incident on the image forming panel 1055. In particular, the light emitted from the third sub FEL 1110c is incident on the second region RG2 of the image forming panel 1055. [

The processor 1070 can control the image forming panel 1055 to adjust the alignment state of the liquid crystal molecules disposed in the second region RG2. For example, the processor 1070 may implement display light for controlling the arrangement of liquid crystal molecules to generate an image on the outside.

The second region RG2 is larger than the first region RG1. In order to display an image with the same brightness, a larger amount of light is required than the amount of light required in the first area RG1. Accordingly, the second light source 1052b and the third light source 1053c can be used to provide the amount of light required in the second region RG2.

15C illustrates an operation in which the third screen SN3 is implemented by the first to third light sources 1051a to 1051c and the first to third sub FELs 1110a to 1110c according to the embodiment of the present invention FIG.

Referring to Fig. 15C, the processor 1070 can control the light output from the first to third light sources 1051a to 1051c based on the received information, signals, and data.

Light output from the first to third light sources 1051a to 1051c is incident on the image forming panel 1055 in a path as described in Figs. 15A and 15B.

Light output from the first light source 1051a and passed through the first sub FEL 1110a is incident on the first region RG1.

Light output from the second light source 1051b and passed through the second sub FEL 1110b is incident on the second region RG2.

Light output from the third light source 1051c and having passed through the third sub FEL 1110c is incident on the second region RG2.

The processor 1070 can control the image forming panel 1055 such that the alignment states of the liquid crystal molecules disposed in the first region RG1 and the liquid crystal molecules disposed in the second region RG2 are adjusted.

In this case, the processor 1070 can control the image forming panel 1055 to display an image in the first area RG1 that requires a certain recognition of the user. For example, if it is necessary to provide a warning to the driver in the driving situation, the processor 1070 can provide the warning image through the first area RG1.

Since the image provided through the first region RG1 is realized by the light output from the first through third light sources 1051a through 1051c, the region excluding the first region RG1 in the second region RG2, May be displayed brighter than the image provided through the < / RTI > In this case, the image provided through the first area RG1 has good visibility.
