Abstract
An apparatus for improving the visibility of objects within the visual field of a vehicle driver and a process therefor are disclosed. The apparatus includes a light caster casting intense visible light toward a reflective object at a frequency no lower than critical fusion frequency, an image pickup device picking up an image of the object and outputting corresponding image data, an image data amplifier, a picture signal generator and a display. The image data are processed to yield a picture signal which yields a clear picture of the object on the display. The apparatus can give the driver of a vehicle a clear picture of the objects within forward visual field of the vehicle at night without dazzling the drivers of vehicles in the opposite lane.
