Abstract:
This virtual image display device projects a display light image (Oi) onto a projection area (PA) of a vehicle (A) and displays a virtual image (Vi) superimposed thereon, and is provided with: a low-frequency information acquisition unit (61) which acquires orientation change information in a low-frequency band (LBA); a high frequency information acquisition unit (32) which acquires orientation change information in a high frequency band (HB); a video rendering unit (67) which renders video data of the aforementioned display light image, in which position shift due to orientation change in the low-frequency band has been corrected; a projection optical unit (50) which projects the display light image on the aforementioned projection area; and an optical correction mechanism (55) which displaces at least part of the optical elements (54, 351) included in the projection optical unit so as to reduce position shift caused by orientation change in the high-frequency band.
