VIRTUAL IMAGE DISPLAY DEVICE, CONTROL METHOD, PROGRAM, AND RECORDING MEDIUM
First Claim
1. A virtual image display device for a moving body, the virtual image display device displaying a virtual image by reflecting a display light emitted from a light source, the virtual image display device comprising:
- a reflection unit including a reflective member which reflects the display light, the reflection unit supported to be openable and closable;
an opening/closing control unit configured to perform at least one of an opening control to open the reflection unit and a closing control to close the reflection unit;
a present position acquisition unit configured to acquire a present position of the moving body; and
a control point acquisition unit configured to acquire a start point or a completion point of the opening control or the closing control of the reflection unit,wherein the opening/closing control unit starts the opening control or the closing control of the reflection unit at a time when the present position acquired by the present position acquisition unit reaches the start point or at a time when the present position acquired by the present position acquisition unit reaches a point that is a predetermined distance away from the completion point.

Abstract
A display system (100) has a navigation device (1) and a head-up display (2) that displays a virtual image (Iv) using a combiner (8). The combiner (8) is equipped with a reflective member reflecting display light, and is supported so as to be openable and closable. The navigation device (1) performs at least one of the opening control and/or the closing control of the combiner (8), and the navigation device (1) carries out the opening/closing control at the time when a predetermined condition is satisfied. For example, the navigation device (1) automatically closes the combiner (8) to enhance the visibility of a driver in an attention necessary section and in a guidance unnecessary section, or automatically closes the combiner (8) to adhere to highway regulations in an HUD restriction area.
