Abstract:
A virtual image display device that displays a virtual image by projecting a display light image to a projection area of a vehicle, includes: a low-frequency information acquisition portion that acquires attitude change information of the vehicle at a low-frequency band; a high-frequency information acquisition portion that acquires attitude change information of the vehicle at a high-frequency band; an image renderer that renders image data of the display light image corrected to reduce misalignment attributed to the attitude change at the low-frequency band; a projection optical unit that includes a display surface to display an original image based on the image data, and projects light of the original image as the display light image; and a display controller that displaces the original image to reduce the misalignment of the virtual image attributed to the attitude change at the high-frequency band.
