The above head-up display is used by being mounted on a moving body such as a vehicle. The light source projects light for forming an image to be recognized as a virtual image by the driver of the moving body (hereinafter referred to as “display image” as appropriate). The first combiner reflects the light projected from the light source to form the first region of the display image and guides it to the driver. The second combiner reflects the light projected from the light source to form a second region different from the first region in the display image, and guides it to the driver. And the 1st combiner and the 2nd combiner differ in the distance to the one projection direction of the light from a light source, and the attachment angle with respect to a light source. By using the first combiner and the second combiner configured as described above, a wide drawing area can be appropriately ensured.

Preferably, in the head-up display, the first area is a part of a drawing area by light projected from the light source, and the second area is the first area of the drawing area. The first combiner has a shorter distance from the light source in the one projection direction of the light than the second combiner.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[Device configuration]
FIG. 1 is a schematic configuration diagram of a head-up display (HUD) 1 according to the present embodiment. The HUD 1 includes a light source 2, a first combiner 3, and a second combiner 4. The HUD 1 is used by being mounted on a moving body such as a vehicle.

The light source 2 is installed on the ceiling of the vehicle via a support member (not shown), and forms an image (hereinafter referred to as “display image” as appropriate) that is visually recognized as a virtual image from the position (eye point) of the driver. The light for projecting toward the 1st combiner 3 and the 2nd combiner 4 is projected. The first combiner 3 and the second combiner 4 are provided below the light source 2, and the light source 2 projects light downward toward the first combiner 3 and the second combiner 4.

Specifically, the light source 2 projects light for forming a display image on the first combiner 3 and the second combiner 4 under the control of the control unit 21. Specifically, the light source 2 projects the light for forming the first region in the display image onto the first combiner 3, and the light for forming the second region different from the first region in the display image is the second combiner. 4 is projected. The first area is an image area that forms an upper part of the display image, and the second area is an image area that forms a lower part of the display image than the first area. For example, the light source 2 forms a display image by scanning a laser beam over a predetermined range. The control unit 21 in the light source 2 includes a CPU, a RAM, a ROM, and the like (not shown) and performs general control on the HUD 1.

The first combiner 3 and the second combiner 4 each project the light projected from the light source 2. The first combiner 3 reflects the light projected from the light source 2 to form the first region described above to the driver's eye point, thereby giving the driver a virtual image Iv1 corresponding to the first region of the display image. Make it visible. The second combiner 4 reflects the light projected from the light source 2 to the driver's eye point in order to form the above-described second region, thereby giving the driver a virtual image Iv2 corresponding to the second region of the display image. Make it visible.

The first combiner 3 is provided above the second combiner 4, in other words, the second combiner 4 is provided below the first combiner 3. Further, the first combiner 3 and the second combiner 4 are both displayed in a display prohibition area Ar1 (for example, stipulated by law), which is indicated by a one-dot chain line in FIG. Are not included in the designated area). The first combiner 3 is provided above the display prohibited area Ar1, and the second combiner 4 is provided below the display prohibited area Ar1.

Furthermore, the first combiner 3 and the second combiner 4 are attached to the vehicle via a support shaft (not shown) and rotate around the support shaft. Thereby, according to the position of a driver | operator's eye so that the light reflected from each of the 1st combiner 3 and the 2nd combiner 4 may enter into a driver | operator's eye appropriately, the 1st combiner 3 and 2nd The mounting angle of the combiner 4 can be changed. Basically, the first combiner 3 and the second combiner 4 tend to have different mounting angles with respect to the light source 2.

Next, the configuration of the first combiner 3 and the second combiner 4 will be described in detail with reference to FIGS. 2 and 3.

FIG. 2 is a diagram for explaining the distance of the light from the light source 2 in the one projection direction for the first combiner 3 and the second combiner 4. Here, the optical distance from the light source 2 to the first combiner 3 and the optical distance from the light source 2 to the second combiner 4 are defined using the distance of the light from the light source 2 in one projection direction. To do. In this case, as shown in FIG. 2, the distance in the projection direction of one light from the light source 2 is defined as the distance from the surface X using the surface X including the position where the light is emitted from the light source 2. To do.

If it prescribes | regulates in this way, about the 1st combiner 3, the distance to the one projection direction of the light from the light source 2 will be "L1", and about the 2nd combiner 4, to the one projection direction of the light from the light source 2. The distance becomes “L2”. As is clear from FIG. 2, it can be seen that the distance L 2 in the light projection direction for the second combiner 4 is longer than the distance L 1 in the light projection direction for the first combiner 3. That is, in the present embodiment, the first combiner 3 and the second combiner 4 are arranged so that the distance from the light source 2 in the one projection direction of the light is longer than that of the first combiner 3. ing.

FIG. 3 shows a diagram for more specifically explaining the positional relationship between the first combiner 3 and the second combiner 4. In the present embodiment, in the light emitted from the light source 2, light for forming an upper portion in the display image (corresponding to light for forming the first region) is incident on the first combiner 3, The first combiner 3 and the second combiner 4 so that the light for forming the lower part of the display image (corresponding to the light for forming the second region) that cannot be received by the first combiner 3 is incident on the second combiner 4. A second combiner 4 is arranged. In other words, in this embodiment, in order to make the light from the light source 2 incident on the first combiner 3 and the second combiner 4 as much as possible in the display prohibited area Ar1 while observing the restriction that no image is displayed in the display prohibited area Ar1. The first combiner 3 and the second combiner 4 are arranged at predetermined positions above and below the display prohibited area Ar1 that are not included.

The arrangement position of the second combiner 4 will be described more specifically. In the present embodiment, as shown by the broken line in FIG. 3, the first combiner 3 is virtually enlarged in the direction of the display prohibition area Ar1 so that the light for forming the second region is incident on the first combiner 3. In such a case, the second combiner 4 is arranged at a position where light after passing through the portion 3a of the first combiner 3 that is virtually enlarged is incident. In this case, light that has passed through the virtually enlarged portion 3a of the first combiner 3 and the display-prohibited area Ar1 is incident on the second combiner 4.

If the first combiner 3 and the second combiner 4 are configured as described above, the optical distance from the light source 2 through the first combiner 3 to the eye point and the light source 2 through the second combiner 4 to the eye The optical distance to the point will be different. Therefore, resolution tends to be different between an image drawn by the first combiner 3 (an image corresponding to the first area) and an image drawn by the second combiner 4 (an image corresponding to the second area). Therefore, the resolution may be changed between the image that is the generation source of the first region in the display image and the image that is the generation source of the second region in the display image. For example, the control unit 21 in the light source 2 performs image processing for lowering the resolution of the image that is the generation source of the display image corresponding to the first area, compared to the image that is the generation source of the display image corresponding to the second area. Alternatively, image processing is performed to increase the resolution of the image that is the generation source of the display image corresponding to the second area, compared to the image that is the generation source of the display image corresponding to the first area. Thus, the control unit 21 corresponds to an example of “image processing means” in the present invention.

[Effects of this embodiment]
Next, the operational effects of the HUD 1 according to the above-described embodiment will be described.

FIG. 4 shows a drawing area by the HUD 1 according to the present embodiment. In FIG. 4, an area surrounded by a thick line indicates an area (drawable area) that can be drawn by the HUD 1. The area has areas Ar2a, Ar2b, and Ar2c. In this specification, a drawable area determined by the drawing ability of the HUD is referred to as a “drawable area”, and an area in which an image is actually drawn in such a drawable area is a “drawn area”. I will call it. The drawing area is determined according to restrictions such as a display prohibition area Ar1 and attachment tolerance.

Areas Ar2a and Ar2c are areas (drawing areas) where an image is actually drawn by the HUD 1. Specifically, the area Ar 2 a is a drawing area by the first combiner 3, and the area Ar 2 b is a drawing area by the second combiner 4. The drawing area Ar2a corresponds to the first area in the display image, and the drawing area Ar2b corresponds to the second area in the display image. On the other hand, an area Ar2c located between the drawing area Ar2a and the drawing area Ar2b is an area that is not recognized by the driver, that is, an area in which no image is drawn. For example, the area Ar 2 c corresponds to an area that cannot be drawn due to a mounting tolerance of the first combiner 3 and the second combiner 4. The display prohibition area Ar1 is included in this area Ar2c. The area Ar2c is an example of the “third region” in the present invention. Light may not be projected onto this area Ar2c (for example, laser off), or light may be actually projected.

As can be seen from FIG. 4, according to the HUD 1 according to the present embodiment, a wide drawing area is secured. That is, according to the present embodiment, it can be said that a wide drawing area can be appropriately secured by using the first combiner 3 and the second combiner 4.

Hereinafter, the operational effects of the present embodiment will be described by presenting a comparative example and comparing with the comparative example.

FIG. 5 is a diagram for explaining the first comparative example and the second comparative example. Fig.5 (a) is a schematic block diagram of HUD1a which concerns on a 1st comparative example. As shown in FIG. 5A, in the HUD 1a according to the first comparative example, only one combiner 5a is provided above the display prohibited area Ar1. FIG. 5B is a schematic configuration diagram of the HUD 1b according to the second comparative example. As shown in FIG. 5B, in the HUD 1b according to the second comparative example, only one combiner 5b1 is provided below the display prohibited area Ar1. Light from the light source 2b is incident on the combiner 5b1 via the mirror 5b2.

Generally, a drawing unit used in a TV or the like is mounted on the light source of the HUD, and the drawing unit has an ability to draw an image having an aspect ratio of 16: 9 or 4: 3. However, in the configuration according to the first comparative example and the second comparative example, the heights of the combiners 5a and 5b1 are limited due to the limitation of the display prohibition area Ar1, and thus the drawing ability in the vertical direction in the drawing unit can be used up. Can not. For example, in the configuration according to the first comparative example and the second comparative example, even if a device having a drawing capability of 1280 × 720 is mounted, only 800 × 300 can be used, and the drawing in the vertical direction is less than half. Only the ability can be used. On the other hand, in the HUD 1 according to the present embodiment, a wide drawing area can be secured by using the first combiner 3 and the second combiner 4 configured as described above (see FIG. 4). The drawing ability by HUD1 can be fully used.

FIG. 6 is a diagram for explaining the third comparative example. FIG. 6A is a schematic configuration diagram of the HUD 1c according to the third comparative example. As shown in FIG. 6A, in the HUD 1c according to the third comparative example, combiners 5c1 and 5c2 (holographic combiners) are provided at positions above and below the windshield not included in the display prohibition area Ar1. . Light from the light source 2c is incident on the combiners 5c1 and 5c2 via the mirror 5c3.

FIG. 6B shows a drawing area by the HUD 1c according to the third comparative example. In FIG. 6B, an area surrounded by a thick line indicates an area that can be drawn by the HUD 1c. The area has areas Ar3a, Ar3b, Ar3c. The area Ar3a is a drawing area by the combiner 5c1, and the area Ar3b is a drawing area by the combiner 5c2. The area Ar3c is an area corresponding to the display prohibition area Ar1, that is, an area where an image cannot be drawn. FIG. 6B shows that according to the configuration according to the third comparative example, a relatively wide area at the center of the drawable area becomes an area where an image cannot be drawn, and thus a wide drawing area cannot be secured. On the other hand, in the HUD 1 according to the present embodiment, by using the first combiner 3 and the second combiner 4 configured as described above, an image cannot be drawn as compared with the configuration according to the third comparative example. Since the area is considerably small (see FIG. 4), a wide drawing area can be appropriately secured.

In the HUD 1c according to the third comparative example, the combiner 5c1 and the combiner 5c2 have the same distance in the projection direction of the light from the light source 2c, and have the same mounting angle with respect to the light source 2c. It has become. Furthermore, in HUD1c which concerns on a 3rd comparative example, it can be said that combiner 5c1 is equivalent to the 1st combiner 3 which concerns on a present Example, and combiner 5c2 is equivalent to the 2nd combiner 4 which concerns on a present Example, As in the present embodiment, the light after passing through the portion where the combiner 5c1 is virtually enlarged in the plane direction is not incident. For this reason, the HUD 1c according to the third comparative example uses two combiners similarly to the HUD 1 according to the present embodiment. However, the configurations of the two combiners are different between the third comparative example and the present embodiment. It can be said. Therefore, the difference of the effect as mentioned above has arisen.

FIG. 7 is a diagram for explaining the fourth comparative example. The fourth comparative example relates to a configuration in which only the first combiner 3 is used without using the above-described second combiner 4, and the first combiner 3 is enlarged to secure a wide drawing area. FIG. 7 shows a drawing area having a configuration according to the fourth comparative example. In FIG. 7, an area surrounded by a bold line indicates a drawable area. The area has areas Ar4a and Ar4b. The area Ar4a is a drawing area by the first combiner 3 according to the fourth comparative example, and the area Ar4b is an area corresponding to the display prohibition area Ar1, that is, an area where an image cannot be drawn.

FIG. 7 shows that the proportion of the display-prohibited area increases only by increasing the first combiner 3. Therefore, the configuration in which the light from the light source 2 is received by a plurality of combiners (the first combiner 3 and the second combiner 4) as in the present embodiment is 1 for the light from the light source 2 as in the fourth comparative example. It can be said that the drawing area can be made larger than the configuration received by two large combiners. Although the HUD 1 according to the present embodiment uses a plurality of combiners (first combiner 3 and second combiner 4), light is projected to each combiner by one light source 2, and therefore light is emitted to each combiner. Compared with a configuration using a plurality of light sources for projecting, the cost can be reduced.

[Modification]
Next, a modification of the above-described embodiment will be described with reference to FIG. In the following description, description of the same configuration as that of the above-described embodiment will be omitted as appropriate. That is, the configuration that is not particularly described is the same as that in the above-described embodiment.

FIG. 8 is a schematic configuration diagram of the HUD 1x according to the modification. The HUD 1x includes a light source 2x, a first combiner 3x, a second combiner 4x, and a mirror 7. In HUD1 which concerns on the above-mentioned Example, although the light source 2 was provided above the 1st combiner 3 and the 2nd combiner 4, in HUD1x which concerns on a modification, a light source is below the 1st combiner 3x and the 2nd combiner 4x. 2x is provided.

The light source 2x projects light for forming a display image toward the mirror 7, and the mirror 7 reflects the light from the light source 2x and makes it incident on the first combiner 3x and the second combiner 4x. Specifically, the light source 2x emits light for forming a display image under the control of the control unit 21x. Specifically, the light source 2x emits light for forming the first region in the display image and emits light for forming the second region in the display image. The first area is an image area that forms a lower part in the display image, and the second area is an image area that forms a part above the first area in the display image. For example, the light source 2x forms a display image by scanning a laser beam over a predetermined range. The control unit 21x in the light source 2x has a CPU, a RAM, a ROM, and the like (not shown), and performs general control on the HUD 1x.

The first combiner 3x and the second combiner 4x are configured as a holographic combiner, and light projected from the light source 2x is projected through the mirror 7. The first combiner 3x guides the light projected from the light source 2x to form the first region described above and transmits it to the driver's eye point by diffracting it with a hologram. As a result, the virtual image Iv1x corresponding to the first region of the display image is visually recognized by the driver. The second combiner 4x guides the light projected from the light source 2x to the driver's eye point by diffracting the light by the hologram in order to form the second region. As a result, the virtual image Iv2x corresponding to the second region of the display image is visually recognized by the driver. The first combiner 3x is an example of the “first optical member” in the present invention, and the second combiner 4x is an example of the “second optical member” in the present invention.

The first combiner 3x is provided below the second combiner 4x. In other words, the second combiner 4x is provided above the first combiner 3x. The second combiner 4x is provided on the windshield of the vehicle. Further, both the first combiner 3x and the second combiner 4x are provided at positions that are not included in the display prohibition area Ar1 indicated by the alternate long and short dash line. The first combiner 3x is provided below the display prohibited area Ar1, and the second combiner 4x is provided above the display prohibited area Ar1.

Here, the distance in the projection direction of light from the light source 2 as defined in the above embodiment is considered (see FIG. 2). In the modified example, since the mirror 7 is provided between the light source 2x and the first combiner 3x and the second combiner 4x, the distance in one projection direction of the light reflected by the mirror 7 may be considered. If it does so, the distance to the one projection direction of the light about the 2nd combiner 4x will become longer than the distance to the one projection direction of the light about the 1st combiner 3x. That is, also in the modified example, the first combiner 3x and the second combiner 4x are arranged so that the second combiner 4x is longer than the first combiner 3x in the distance of the light in the one projection direction.

Further, in the modified example, in the light emitted from the light source 2x, light for forming a lower portion in the display image (corresponding to light for forming the first region) is incident on the first combiner 3x, The first combiner 3x so that the light for forming the upper part in the display image (corresponding to the light for forming the second region) that cannot be received by the first combiner 3x is incident on the second combiner 4x. And the 2nd combiner 4x is arrange | positioned. That is, in the modified example, the display prohibition area Ar1 includes the display combiner 3x and the second combiner 4x so that the light from the light source 2x is incident as much as possible while complying with the restriction that no image is displayed in the display prohibition area Ar1. The first combiner 3x and the second combiner 4x are arranged at predetermined positions above and below the display prohibition area Ar1. The arrangement position of the second combiner 4x will be described in detail. In the modification, the first combiner 3x is virtually arranged in the direction of the display prohibition area Ar1 so that the light for forming the second region is incident on the first combiner 3x. When expanded, the second combiner 4x is arranged at a position where light after passing through the portion 3xa of the virtually expanded first combiner 3x is incident.

Even with the HUD 1x according to the modification described above, a wide drawing area can be appropriately secured by using the first combiner 3x and the second combiner 4x.

Even in the modified example, resolution tends to be different between an image drawn by the first combiner 3x (an image corresponding to the first area) and an image drawn by the second combiner 4x (an image corresponding to the second area). Therefore, the control unit 21x in the light source 2x can perform a process of changing the resolution between the image that is the generation source of the first region in the display image and the image that is the generation source of the second region in the display image. .

The present invention is mounted on a moving body such as a vehicle, and is suitably used for visually recognizing an image as a virtual image from the position of the user's eyes.
