In the second animation display, a virtual image imitating the decorative member 2 is animated to a position where it is superimposed on the decorative member 2 with the light source 9 turned off. Various examples of the first animation display and the second animation display will be described below with reference to the figures.

The virtual image display device 6 performs various effects by displaying the first animation and the second animation of the decorative image. The decorative image is not an image of a specific shape or size, but a general term for a virtual image that imitates the decorative member 2. In other words, a decorative image is a general term for a virtual image that imitates an annular member. The size, color, posture, brightness, etc. of the decorative image are arbitrary.

Of the decorative images, FIGS. 5 and 6 show decorative images 30 and 31 displayed superimposed on the decorative member 2. FIG. 5 shows a decorative image 30 in a lighting mode. The decorative image 30 in the lighting mode is a virtual image imitating the decorative member 2 when the light source 9 is lit. FIG. 6 shows a decorative image 31 in a mode when the light is turned off. The decorative image 31 in the mode when the light is turned off is a virtual image imitating the decorative member 2 when the light source 9 is turned off.

The decorative image 30 in the lighting mode shown in FIG. 5 is displayed so as to be superimposed on the decorative member 2 to decorate the decorative member 2. When the decorative image 30 is displayed superimposed on the decorative member 2, the decorative member 2 is illuminated by the light of the light source 9 to the driver even when the light source 9 is actually turned off. It looks as if. The decorative image 31 of the mode when the light is turned off shown in FIG. 6 is displayed so as to be superimposed on the decorative member 2 to decorate the decorative member 2.

When the virtual image display device 6 superimposes a decorative image (for example, decorative images 30 and 31) on the decorative member 2, the virtual image display device 6 superimposes the decorative image on the decorative member 2 when viewed from the eye point of the vehicle. Display it. That is, the virtual image display device 6 projects the decorative image on the region of the half mirror 62 that overlaps with the decorative member 2 when viewed from the eye point.

The decorative image when displayed superimposed on the decorative member 2 is an annular virtual image, and the shape and size conform to the shape and size of the decorative member 2. In the present embodiment, the shape and size of the decorative image when displayed superimposed on the decorative member 2 is substantially the same as the shape and size of the decorative member 2.

As shown in FIG. 5, the decorative image 30 in the lighting mode has high-luminance portions 30a and 30b and low-luminance portions 30c and 30c. The high-luminance portions 30a and 30b and the low-luminance portion 30c correspond to the high-luminance portions 2a and 2b and the low-luminance portion 2c of the decorative member 2 (FIG. 4) illuminated by the light of the light source 9. That is, the high-luminance portions 30a and 30b are displayed superimposed on the high-luminance portions 2a and 2b of the decorative member 2. The low-luminance portion 30c is displayed superimposed on the low-luminance portion 2c of the decorative member 2.

The high-brightness portions 30a and 30b imitate the high-brightness portions 2a and 2b of the decorative member 2. That is, the colors of the high-luminance portions 30a and 30b, the magnitude of the luminance, the distribution of the luminance and the like are similar to the colors of the high-luminance portions 2a and 2b, the magnitude of the luminance, the distribution of the luminance and the like. The low-brightness portion 30c imitates the low-brightness portion 2c of the decorative member 2. That is, the color, the magnitude of the luminance, the distribution of the luminance, etc. of the low-luminance portion 30c are similar to the color, the magnitude of the luminance, the distribution of the luminance of the low-luminance portion 2c, and the like.

The decorative image 30 in the lighting mode is displayed, for example, when the light source 9 is switched from the lighting state to the lighting state, or when the light source 9 is switched from the lighting state to the lighting state. Since the decorative image 30 of the lighting mode is displayed, it is difficult for the driver to notice that the light source 9 has been switched to the off state or the lighting state. Therefore, the transition from the state in which the decorative member 2 is illuminated by the light source 9 to the animation of the decorative image in the state in which the light source 9 is turned off proceeds without discomfort.

As shown in FIG. 6, the decorative image 31 in the light-off mode has a smaller brightness contrast than the decorative image 30 in the light-on mode. The decorative image 31 in the mode when the light is turned off may be, for example, an image in which the brightness does not substantially change along the circumferential direction or the radial direction. In other words, the decorative image 31 in the state when the light is turned off may be an image having uniform brightness.

The vehicle display device 1 of the present embodiment performs the ring slide effect described below. The ring slide effect is executed in response to an operation input by the driver. More specifically, the ring slide effect is executed in the selection mode for selecting the color, pattern, or the like of the decorative member 2. The virtual image display device 6 changes the color and pattern of the virtual image to be displayed on the decorative member 2 as if the color and pattern of the decorative member 2 have changed. In the selection mode, the virtual image display device 6 slides decorative images having different colors and patterns in the horizontal direction of the image and superimposes them on the decorative member 2.

At the start of the ring slide effect, the display control device 63 superimposes the decorative image 32 on the decorative member 2 and displays it. FIG. 7 shows a state in which the light source 9 is turned off and the decorative image 32 is displayed superimposed on the decorative member 2. The decorative image 32 is displayed in the mode when it is turned off. The decorative image 32 is a decorative image 32 having a currently selected color or pattern, or a decorative image 32 having a predetermined color or pattern.

The decorative image 32 is displayed so as to overlap with the decorative member 2 when viewed from the eye point of the vehicle. The display control device 63 of the present embodiment displays the decorative image 32 from a state in which the light source 9 is turned off and the decorative member 2 is substantially invisible. At this time, the display control device 63 may cause the virtual image display device 6 to perform a fade-in animation that gradually increases the brightness of the decorative image 32. The fade-in of the decorative image 32 looks to the driver as if the lighted decorative member 2 stands out.

The virtual image display device 6 slides out the decorative image 32 and slides in another decorative image 33 in response to an operation input by the driver or automatically. The decorative image 33 is a virtual image that is superimposed on the decorative member 2 and displayed to decorate the decorative member 2. The color and pattern of the decorative image 33 are different from the color and pattern of the decorative image 32. As shown in FIG. 8, the virtual image display device 6 slides out the decorative image 32 to the left side (arrow Y1) and slides the decorative image 33 in from the right side (arrow Y2). The virtual image display device 6, for example, slides the decorative image 32 and the decorative image 33 toward the left side at the same speed. While the decorative image 32 and the decorative image 33 are moving, the light source 9 is turned off and the decorative member 2 is not substantially visible. In the present embodiment, the animation of the decorative image 32 corresponds to the first animation display, and the animation of the decorative image 33 corresponds to the second animation display.

As shown in FIG. 8, the other images 24 and 25 are masked at the portion overlapping the decorative image 32 and the decorative image 33. As a result, the decorative member 2 appears to move across the front side of the images 24 and 25.

When the virtual image display device 6 moves the decorative image 33 to a position where it overlaps with the decorative member 2, the virtual image display device 6 stops the movement of the decorative image 33 as shown in FIG. The virtual image display device 6 stops the movement of the decorative image 33, and then shifts the display mode of the decorative image 33 from the mode when it is turned off to the mode when it is turned on. FIG. 10 shows a decorative image 33 in a lighting mode. The decorative image 33 in the lighting mode has high-luminance portions 33a and 33b and low-luminance portions 33c and 33c. The display control device 63 turns on the light source 9 when the aspect of the decorative image 33 is changed to the aspect at the time of lighting. Since the decorative image 33 imitating the illuminated decorative member 2 is displayed, it is difficult to notice that the light source 9 has been switched to the lit state.

When the driver inputs an operation for determining the decorative image 33, the display control device 63 ends the selection mode while displaying the decorative image 33 in the lighting mode. On the other hand, the display control device 63 replaces the decorative image when the operation input for determining the decorative image 33 is not made or when the operation input for commanding the display of another decorative image is made. In this case, the display control device 63 turns off the light source 9 and shifts the display mode of the decorative image 33 from the lighting mode (FIG. 10) to the lighting mode (FIG. 9). The transition of the display mode is performed, for example, after the light source 9 is turned off. When the transition of the display mode is completed, the display control device 63 slides out the decorative image 33 and slides in the decorative image of another color or pattern. The display control device 63 repeats the slide-in and slide-out of the decorative image until the driver determines one of the decorative images.

By displaying the animation as described above in the selection mode, the driver can see that the decorative member 2 is actually moving in the lateral direction of the image. That is, the driver feels as if the decorative members 2 having different colors and patterns appear one after another. As described above, the vehicle display device 1 of the present embodiment realizes the virtual operation of the decorative member 2 by combining the decorative member 2 whose position is fixed with the animation of the virtual image. Therefore, the vehicle display device 1 of the present embodiment can improve the design and the effectability without using the drive mechanism for moving the decorative member 2.

The vehicle display device 1 of the present embodiment performs the first animation display when the display mode is changed, as described below. The vehicle display device 1 of the present embodiment has a plurality of display modes in which the contents to be displayed in the image display area 10 are different. The display mode includes a first display mode in which various information is displayed with the light source 9 turned on, and a second display mode in which various information is displayed with the light source 9 turned off.

In the first display mode, the decorative member 2 is used as a frame for the boundary of the display area. The first display mode is a vehicle speed display mode in which an image showing the traveling speed of the vehicle is displayed inside the decorative member 2, and an image showing the rotation speed of the engine is displayed inside the decorative member 2. Includes rotation speed display mode.

In the second display mode, various information is displayed in a state where the decorative member 2 is not substantially visible. The second display mode includes a navigation display mode, a multimedia display mode, a menu mode, and the like. In the second display mode, the decorative member 2 is not visually recognized, and the image display area 10 is not divided by the decorative member 2. Therefore, the degree of freedom in layout when displaying a virtual image in the image display area 10 is improved.

FIG. 11 shows a decorative image 34 before the start of changing the display mode. The display mode of the decorative image 34 in FIG. 11 is a mode when the decorative image 34 is lit. The decorative image 34 has high-luminance portions 34a and 34b and low-luminance portions 34c and 34c. The light source 9 is lit. The display control device 63 starts the effect of changing the display mode when the driver inputs the operation for changing the display mode. The change of the display mode illustrated here is a change from the vehicle speed display mode to the navigation display mode.

When the display mode change is commanded, the display control device 63 turns off the light source 9 and shifts the display mode of the decorative image 34 from the lighting mode to the lighting mode. The transition of the display mode may be performed substantially at the same time as the light source 9 is turned off, or may be performed after the light source 9 is turned off. FIG. 12 shows a decorative image 34 of the mode when the light is turned off. In the decorative image 34 of the mode when the light is turned off, the brightness of each part is equivalent to the brightness of the high-brightness parts 34a and 34b in the mode when the light is turned on.

The display control device 63 executes the first animation display when the transition of the display mode is completed. The display control device 63 animates the decorative image 34 from a position where it overlaps with the decorative member 2 with the light source 9 turned off. The first animation display when shifting to the navigation display mode is an animation that imitates the tilting motion of the decorative member 2 (hereinafter, simply referred to as "tilting animation").

The display control device 63 displays an animation that imitates the movement of the decorative member 2 tilting toward the back side while advancing toward the back side in the tilting animation. FIG. 13 shows a decorative image 34 displayed at the initial stage of the tilt animation. The width W1 of the decorative image 34 of FIG. 13 is smaller than the width W0 of the decoration image 34 of FIG. The change from the width W0 to the width W1 expresses the movement of the decorative member 2 toward the back surface side. Further, the shape of the decorative image 34 in FIG. 13 is a shape that imitates a state in which the decorative member 2 is inclined toward the back surface side. That is, the decorative image 34 of FIG. 13 is an image simulating a state in which the outer peripheral surface and the inner peripheral surface of the decorative member 2 are visually recognized as the decoration member 2 is tilted. Further, in FIG. 13, in the decorative image 34, the tilted posture is expressed by the length in the vertical direction of the image being shorter than the length in the horizontal direction of the image.

FIG. 14 shows a decorative image 34 displayed in the latter part of the tilt animation. The width W2 of the decorative image 34 of FIG. 14 is smaller than the width W1 of the decoration image 34 of FIG. Further, in the area inside the decorative image 34, a vehicle image 21 which is a virtual image imitating a vehicle is displayed. The vehicle image 21 is an image imitating a vehicle viewed from diagonally rearward. The change from the width W0 to the width W1 and the width W2 may be considered to indicate a change in the viewpoint position in the virtual space. That is, the change in the width may be considered to represent that the position of the decorative member 2 moves from the position facing the driver to the position looking down diagonally.

FIG. 15 shows a decorative image 34 that is displayed when the tilt animation is completed. In the image display area 10, in addition to the decorative image 34, a road image 22 and a structure image 28 are displayed. The road image 22 is a virtual image that imitates the road on which the own vehicle is traveling. The structure image 28 is a virtual image that imitates a building or the like around a road.

By the tilting animation, it is possible to produce an effect as if the decorative member 2 actually performs the tilting motion. Further, by changing the width of the decorative image 34 as if the decorative member 2 moves toward the back side, a sense of depth can be produced. Further, by displaying the vehicle image 21 in addition to the decorative image 34, the stereoscopic effect of the navigation screen can be improved.

When transitioning from the second display mode to the first display mode, a standing animation is performed. The standing animation is an animation that imitates the standing motion of the decorative member 2. In the standing animation, contrary to the tilting animation, the motion of the decorative image 34 moving toward the front side and standing toward the front side is expressed (FIG. 15 → FIG. 14 → FIG. 13 → FIG. 12). The virtual image display device 6 animates the decorative image 34 toward a position where it overlaps with the decorative member 2. That is, the standing animation corresponds to the second animation display. When the entire decorative image 34 is superimposed on the decorative member 2, the standing animation is completed. When the standing animation is completed, the display control device 63 turns on the light source 9 and shifts the display mode of the decorative image 34 to the lighting mode. The transition of the display mode may be performed substantially at the same time as the lighting of the light source 9, or may be performed after the lighting of the light source 9.

The vehicle display device 1 of the present embodiment performs the disappearance / appearance animation described below. The disappearance / appearance animation is performed, for example, at the opening of the vehicle display device 1.
