Abstract

The HUD (100) is a virtual image display device that displays a virtual image (Vi) that can be visually recognized by the driver of the vehicle (A). The HUD (100) switches the position of the View Angle (VA) for displaying the virtual image (Vi) between a plurality of positions including a normal position (VP 1) and an overlapped position (VP 2) by an actuator. The HUD (100) displays virtual images (Vi) respectively associated with a normal position (VP 1) and an overlapping position (VP 2) according to the switching of the positions of the View Angles (VA) based on the actuators. When the specific Content (CTis) is displayed within the view angle at the overlapping position (VP 2) after the View Angle (VA) is moved from the normal position (VP 1) to the overlapping position (VP 2), the HUD (100) starts to display the associated content (CTr) which is associated with the specific Content (CTis) in advance before the movement of the View Angle (VA) to the overlapping position (VP 2) is completed.

Description

Virtual image display device and display system Cross Reference to Related Applications The present application is based on japanese patent application nos. 2020-174732 of the japanese application on 10/16/2020 and on japanese patent application nos. 2021-15013 of the japanese application on 9/15/2021, the contents of the basic applications being incorporated by reference in their entirety. Technical Field The disclosure based on the present specification relates to a virtual image display device and a display system that display a virtual image that can be visually recognized by an occupant of a vehicle. Background Patent document 1 discloses a head-up display device including an adjustment mechanism for mechanically moving a projection range of light projected as a display image displayed as a virtual image. As scene adaptation control, the head-up display device moves the position of the projection range by an adjustment mechanism so that the entire display with a high display priority is displayed. Patent document 1 Japanese patent application laid-open No. 2019-189139 In the structure including a mechanism for moving the position of the angle of view at which the virtual image is displayed as in patent document 1, it takes time for the mechanical movement of the angle of view position. Therefore, when processing for displaying a specific content in a viewing angle after movement is performed after movement of the viewing angle is completed, a time lag before display start due to movement of the viewing angle occurs. If such a time lag is perceived by an occupant of the vehicle, the occupant is likely to feel a sense of incongruity even if the angle of view from which the virtual image can be displayed can be expanded. As a result, there is a concern that the convenience of the virtual image display device is impaired. Disclosure of Invention The purpose of the present disclosure is to provide a virtual image display device and a display system that can improve convenience. In order to achieve the above object, one embodiment of the present invention provides a virtual image display device for displaying a virtual image visually recognizable by an occupant of a vehicle, the device including a switching mechanism for switching a position at which a viewing angle of the virtual image is displayed between a plurality of positions including a first position and a second position, and a display control unit for displaying the virtual image associated with the first position and the second position, respectively, in accordance with the switching of the positions based on the viewing angle of the switching mechanism, wherein when the switching mechanism moves the viewing angle from the first position to the second position and then displays a specific content within the viewing angle of the second position, the display control unit starts displaying associated content associated with the specific content in advance before the movement of the viewing angle to the second position is completed. In this manner, the associated content, which is associated with the specific content in advance, is displayed before the movement of the angle of view from the first position to the second position is completed, and therefore a time lag before the start of display caused by the movement of the angle of view based on the switching mechanism is hardly perceived by the occupant of the vehicle. Therefore, even if the switching mechanism is provided to expand the angle of view at which the virtual image can be displayed, the sense of incongruity of the display can be reduced. As a result, convenience of the virtual image display device can be improved.
