Incidentally, in the vehicle display device described in Patent Document 1 described above, for example, the basic image provided in the pointer image and the border image (simulating gradation) are positioned closer to the vehicle user (observer side) than the index image. If the pointer image is overlapped with the index image (that is, when the pointer image indicates a specific index image), the border image is provided around the core image. With the provision of the border image, the visible area of the (specific) index image is reduced, and the legibility of the index image may be degraded.
Accordingly, the present invention provides a display device for a vehicle in which, when the pointer image indicates a specific index image, the legibility of the specific index image is not likely to deteriorate in order to cope with the above-described problem. It is intended.

  The present invention includes an image display device that displays a vehicle information image composed of an index image displayed in a predetermined arrangement form and a pointer image indicating a specific index image, and the pointer image is In the vehicular display device that includes a basic image constituting the main body of the pointer image and a border image that borders the basic image, when the vehicular display device is viewed from an observer side, the basic image is When the index image is located closer to the observer than the index image, the index image is located closer to the observer than the border image, and the pointer image and the index image overlap, the border The border image portion of the image that overlaps the index image is invisible to the observer side.

  According to the present invention, it is possible to provide a display device for a vehicle that can achieve the initial purpose and does not have a possibility of degrading the legibility of the specific index image when the pointer image indicates the specific index image.

The front view of the display apparatus for vehicles by the embodiment of the present invention. The block diagram which shows the electrical constitution of the display apparatus for vehicles by the embodiment. FIG. 3 is a perspective view showing a pointer image, an index image, and a border image according to the embodiment. The principal part front view of the display apparatus for vehicles by the embodiment.

  Hereinafter, the case where the embodiment of the present invention is applied to a vehicle instrument capable of displaying a speedometer image will be described as an example with reference to FIGS.

  1 and 2, the vehicular instrument as the vehicular display device according to the present embodiment includes an image display device 10, a control means 20, and an input terminal 30, and the image display device 10 is, for example, used by a vehicle. A flat panel display composed of a liquid crystal display panel capable of displaying a predetermined vehicle information image can be applied to an observer (observer). In this example, the front of the vehicle user sitting in the driver's seat of the vehicle It is installed in the instrument panel located in The image display device 10 may be an organic EL panel instead of a liquid crystal display panel.

  As shown in FIG. 1, the image display device 10 is configured to display a speedometer image 11 that displays, for example, the traveling speed of the vehicle as a pointer-type image on the screen.

  The speedometer image 11 is an image simulating a mechanical pointer instrument, and indicates a value corresponding to vehicle speed information input through the input terminal 30 under the control of the control means 20. .

  The speedometer image 11 (image display device 10) includes an index image 12 displayed with an arcuate array form (predetermined array form), and a pointer image 13 indicating a specific index image 12. A vehicle information image is displayed.

  The index image 12 is composed of a numerical image 12a and a scale image 12b that are both displayed in an arcuate arrangement. The scale image 12b is displayed outside the numerical image 12a so as to correspond to the numerical image 12a. .

  That is, the index image 12 composed of the number image 12a and the scale image 12b is displayed in an arc shape along the operation range (rotation range) of the pointer image 13, and is indicated by the pointer image 13. Thus, the vehicle user can know the change in the traveling speed of the vehicle by comparing and interpreting the index image 12 and the pointer image 13.

  The pointer image 13 indicates a specific index image 12 (a specific numeric image 12a and a specific scale image 12b), and is a basic line extending linearly so as to constitute a main body (main part) of the pointer image 13. The image 13a has a blurred image 13b whose outer shape is slightly larger than the outer shape of the basic image 13a, and the blurred image 13b is displayed in a color tone different from the color tone of the index image 12 and the basic image 13a. .

  In this case, as shown in FIG. 4, when the vehicle instrument is viewed from the vehicle user side, the blurred image 13b is a substantially frame provided so as to border (enclose) the periphery of the linear image 13a that extends linearly. It is displayed as a border image 14 having a shape. Accordingly, when the vehicle instrument is viewed from the vehicle user side, the pointer image 13 has the above-described basic image 13a and the above-described border image 14.

  Here, paying attention to the positional relationship among the numerical image 12a, the scale image 12b, the basic image 13a, and the border image 14 (blurred image 13b), as shown in FIG. 3, the vehicle user side (observer side) indicated by reference numeral 15 is shown. The basic image 13a is located closest to the numerical image 12a, the numeric image 12a is located behind the basic image 13a, the border image 14 (blurred image 13b) is located behind the numeric image 12a, and the border image 14 (blurred image). A scale image 12b is located behind the image 13b).

  In other words, when the vehicle instrument (vehicle display device) is viewed from the vehicle user side (observer side), the basic image 13a is positioned closer to the vehicle user side than the numeric image 12a of the index image 12. In addition, the numerical image 12a of the index image 12 is located closer to the vehicle user than the border image 14 (blurred image 13b). Further, the border image 14 (blurred image 13b) is located closer to the vehicle user than the scale image 12b of the index image 12.

  In the case of this example, as shown in FIG. 4, when the index image 12 (particularly the numeric image 12a of the index image 12) and the pointer image 13 overlap, the index of the border image 14 that borders the basic image 13a. The border image 14 portion overlapping the image 12 (numerical image 12a) is in a state (invisible state) invisible from the vehicle user side.

  That is, when the index image 12 (numerical image 12a) and the pointer image 13 overlap, the numerical image 12a is positioned on the vehicle user side with respect to the border image 14 as described above. When the vehicular instrument is viewed from the vehicle user side, only the numeric image 12a is visible from the vehicle user side in the overlapping region where the numerical image 12a and the border image 14 overlap, and the overlapping is performed. The border image 14 portion located in the region is not visible.

  Therefore, as shown in FIG. 4, when the numeral image 12a and the pointer image 13 overlap (that is, when the pointer image 13 indicates a specific numeral image 12a), the border image 14 is converted into the numeral image 12a. (In other words, the border image 14 portion of the border image 14 that overlaps the numeric image 12a of the index image 12 is invisible from the vehicle user side). Therefore, the visible area of the specific numeric image 12a indicated by the pointer image 13 is larger than the conventional area, and the legibility of the specific numeric image 12a indicated by the pointer image 13 is improved. be able to.

  The control unit 20 includes a microcomputer 21 including a storage device such as a ROM, a RAM, a nonvolatile memory, and a flash memory, and a vehicle including an index image 12 and a pointer image 13 in response to a command signal from the microcomputer 21. In order to display an information image on the image display device 10, the image display device 10 includes a graphic controller 22 that performs a display operation.

  The microcomputer 21 processes the vehicle speed information input through the input terminal 30 and controls the speedometer image 11 to be displayed on the image display device 10 based on the control of the graphic controller 22. Then, a speedometer image 11 composed of the index image 12 and the pointer image 13 is displayed on the screen of the image display device 10.

  As described above, in the present embodiment, the image display device 10 that displays the vehicle information image including the numeral image 12a displayed with the arc-shaped arrangement form and the pointer image 13 indicating the specific numeral image 12a is provided. In the vehicular instrument, the pointer image 13 includes a basic image 13a that constitutes the main body of the pointer image 13 and a border image 14 that borders the basic image 13a, on the vehicle user side (observer side) When the vehicular instrument is viewed from above, the basic image 13a is located closer to the observer than the numeric image 12a, and the numeric image 12a is located closer to the observer than the border image 14, When the numerical image 12a overlaps, the border image 14 portion of the border image 14 that overlaps the numerical image 12a is invisible to the viewer.

  Therefore, when the numerical image 12a and the pointer image 13 overlap (that is, when the pointer image 13 indicates a specific numerical image 12a), the border image 14 avoids the display position of the numerical image 12a. Since the basic image 13a is bordered, the visible area of the specific numeric image 12a indicated by the pointer image 13 is larger than the conventional one, and the readability of the specific numeric image 12a may be reduced. It is possible to provide an in-vehicle instrument (vehicle display device) that does not exist.

  In this embodiment, the example in which the speedometer image 11 is displayed on the image display device 10 has been described. However, various vehicle information images (for example, tachometer images) other than the speedometer image 11 displayed on the image display device 10 are described. However, it goes without saying that the present invention can be applied.
