Abstract: The invention relates to an anti-glare device comprising a camera, a visualisation means for reproducing a processed image, and an adaptable filter comprising a filtering image controlled by the camera, said image containing masking regions which obscure the dazzling regions. The inventive device is characterised in that it comprises a single camera provided with an output connected to an electronic circuit which controls the filter for the alternate display of an acquisition image and a filtration image calculated according to the image transmitted by the camera during the previous acquisition phase. The invention also relates to the method implemented by one such device, and to an accessory for a photographing device.

Abstract: The invention relates to a low-beam headlight system for at least two motor vehicles, comprising a first illuminating device on a first vehicle and a second illuminating device on a second vehicle, each of the devices being provided with main road illuminating means. The first device furthermore comprises additional illuminating means directed laterally with respect to the longitudinal axis of said first vehicle emitting in a predetermined wavelength band, and the second device comprises an electronic road viewing equipment able to capture and retrieve an image of said road when it is illuminated in said predetermined wavelength band by said lateral illuminating means. The system furthermore comprises means of reducing the dazzling of said second vehicle when the additional illuminating means are activated and/or detected by the second device.

Abstract: A driving aid device for a vehicle comprises a means for imaging and a means for projecting a virtual image in a field of vision of a driver, an opaque screen, arranged in the field of view of the driver, for the formation of a virtual image focused at infinity in the field of vision of the driver of the vehicle, and further comprises means for filtration of zones of high luminous intensity.

Abstract: An optical device including a dynamic filer of a source of very strong luminosity, wherein the filter includes a mirror with a zone of less reflection and a controller of the position of the mirror as a function of the position of the source of very strong luminosity in the image formed on the mirror.

Abstract: A dynamic optical filtration system and method effectively blocks bright light sources without impairing view of the remainder of the scene. A sensor measures light intensity and position so that selected cells of a shading matrix may interrupt the view of the bright light source by a receptor. A beamsplitter may be used so that the sensor may be located away from the receptor. The shading matrix may also be replaced by a digital micromirror device, which selectively sends image data to the receptor.
