Abstract

A vehicular display device, in which positional adjustment of a display image is easy, is provided, and the vehicular display device (head-up display) 1 comprises a display 3 to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means (motor) 7 for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means (control unit) 14 to allow driving of the moving means 7, and control means 11 for displaying a mark indicative of a display range of the display image when the operation means 14 is operated.

Claims

1. A vehicular display device comprising a display to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means to allow driving of the moving means, and control means for displaying a mark indicative of a display range of the display image when the operation means is operated.

2. The vehicular display device according to claim 1, wherein the control means displays a frame mark provided as the mark in a manner to surround the display range of the display image.

3. The vehicular display device according to claim 2, wherein the frame mark comprises a disconnected frame surrounding a periphery of the display range of the display image, or parentheses positioned at ends of the display range of the display image.

4. The vehicular display device according to any one of claims 1 to 3, wherein the control means displays a background mark as the mark such that a background portion of the display range of the display image except the display image is displayed in a different display color from that of the display image.

5. The vehicular display device according to claim 4, wherein the background mark has gradation, in which density is varied from a center of the display range of the display image to a periphery thereof.

6. A vehicular display device comprising a display to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means to allow driving of the moving means, and control means for reversedly displaying luminous locations, which constitute the display image, and non-luminous locations except the luminous locations in a display range of the display image when the operation means is operated.

7. The vehicular display device according to claim 6, wherein at the time of reversedly displaying the luminous locations and the non-luminous locations, the control means makes luminance less than luminance prior to the reversal.

8. A vehicular display device comprising a display to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means to allow driving of the moving means, and control means for causing luminous displaying of a whole display range of the display image when the operation means is operated.

9. The vehicular display device according to claim 8, wherein at the time of luminous displaying of the whole display range, the control means makes luminance less than luminance of the display image.

10. A vehicular display device comprising a display to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means to allow driving of the moving means, and control means for displaying a mark indicative of a display range of the display image when the operation means is operated, and displaying a first display portion corresponding to a direction, in which the display image is moved by the operation means, in a different manner from a second display portion being another display portion.

11. The vehicular display device according to claim 10, wherein the control means displays the mark indicative of the display range of the display image when the operation means is operated, and flashing-displays the display portion of the mark corresponding to the direction, in which the display image is moved by the operation means.

12. The vehicular display device according to claim 10 or 11, wherein the control means displays the mark indicative of the display range of the display image when the operation means is operated, and displays the display portion of the mark corresponding to the direction, in which the display image is moved by the operation means, in a different color from that of another display portion.

13. The vehicular display device according to any one of claims 10 to 12, wherein the control means displays a frame mark provided as the mark in a manner to surround the display range of the display image.

14. A vehicular display device comprising a display to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means to allow driving of the moving means, and control means for displaying a mark indicative of a display range of the display image when the operation means is operated, and holding displaying of the mark for a predetermined period of time after operation of the operation means is not performed.

15. The vehicular display device according to claim 14, wherein the control means displays a frame mark provided as the mark in a manner to surround the display range of the display image.

16. The vehicular display device according to claim 14, wherein the control means displays a background mark as the mark such that a background portion of the display range of the display image except the display image is displayed in a different display color from that of the display image.

17. The vehicular display device according to any one of claims 14 to 16, further comprising holding time modifying means for varying a period of time, in which displaying of the mark is held.
