Document Type and Number:
WIPO Patent Application WO/2018/159319
Kind Code:
A1
Abstract:
Provided are a head-up display device and an onboard display system capable of improving the visual appeal of a virtual image, from among multiple virtual images, that is associated with an actual scene. A HUD device displays a first virtual image V1, which is associated with an actual scene, and a second virtual image V2, which is not associated with the actual scene. The HUD device is equipped with a HUD control unit that sets the luminescence G1 of the first virtual image V1 to be higher than the luminescence G2 of the second virtual image V2 by a luminescence difference X, and sets the luminescence difference X to be larger as a light control value I2 increases, such value being determined on the basis of the intensity of external light.
