Vehicular forward-vision display system decreasing luminance with decreasing vehicle speed

Abstract

A vehicular forward-vision display system includes a night-vision camera for scanning a nighttime image ahead of a vehicle and a head-up display for displaying the scanned nighttime image as a virtual image on a front windshield. Luminance of the displayed image is decreased with decreasing vehicle speed. The luminance of the nighttime image is thereby decreased under a low speed where vision aid is not so necessary. This decreasing of the luminance results in giving a driver relief from botheration of being caught by the scanned image displayed on the front windshield.
