Patent Images
1. An electronic apparatus comprising:
- display means configured to display a first image;
projecting means capable of displaying a virtual image of a second image at least in a first position near the display means or in a second position distant therefrom on a windshield of a vehicle by adjusting a focal length of the virtual image;
determining means configured to determine whether the virtual image of the second image is to be displayed in the first position or in the second position;
adjusting means configured to adjust the focal length of the virtual image in the projecting means on the basis of the determination by the determining means; and
,cooperation determining means configured to determine whether the projecting means is to cooperate with the display means on the basis of correlation between the first image and the second image, wherein the first image and the second image have correlation with each other when at least part of the first image is common to the second image; and
,wherein the adjusting means adjusts the focal length of the virtual image when it is determined that the projecting means is to cooperate.

Abstract
A vehicle-mounted apparatus includes a cluster display unit attached to an instrument panel and a HUD. The vehicle-mounted apparatus determines a running state of the vehicle and adjusts the focal length in the HUD such that the position of a virtual image of a projected image is near the cluster display unit or is a forward position on the windshield.

16. An electronic apparatus comprising:
-
display means configured to display a first image; projecting means capable of displaying a virtual image of a second image at least in a first position near the display means or in a second position distant therefrom on a windshield of a vehicle by adjusting a focal length of the virtual image; determining means configured to determine whether the virtual image of the second image is to be displayed in the first position or in the second position; adjusting means configured to adjust the focal length of the virtual image in the projecting means on the basis of the determination by the determining means; and
,cooperation determining means configured to determine whether the projecting means is to cooperate with the display means, wherein the adjusting means adjusts the focal length of the virtual image when it is determined that the projecting means is to cooperate; wherein the adjusting means adjusts the focal length of the virtual image in the projecting means in proportion to a distance to arrival at a destination determined by the determining means; and
,wherein when it is determined by the determining means that the vehicle has arrived at the destination, information about the destination is displayed by the display means as at least part of the first image.

17. An electronic apparatus comprising:
-
display means configured to display a first image; projecting means capable of displaying a virtual image of a second image at least in a first position near the display means or in a second position distant therefrom on a windshield of a vehicle by adjusting a focal length of the virtual image; determining means configured to determine whether the virtual image of the second image is to be displayed in the first position or in the second position; adjusting means configured to adjust the focal length of the virtual image in the projecting means on the basis of the determination by the determining means; and
,cooperation determining means configured to determine whether the projecting means is to cooperate with the display means, wherein the adjusting means adjusts the focal length of the virtual image when it is determined that the projecting means is to cooperate; wherein the adjusting means adjusts the focal length of the virtual image in the projecting means in proportion to a distance to arrival at a destination determined by the determining means; and
,wherein when it is determined by the determining means that a running state of the vehicle changes from vehicle standstill, at least part of the first image displayed on the display means is displayed by the projecting means as the virtual image of the second image.
