Albou Pierre: Night vision improvement method esp. for driver of motor vehicle. Valeo Vision, April 26, 1996: FR2726144-A1 (95 worldwide citation)

The method involves using a camera (20) with a matrix array of e.g. 256 x 256 CCD image sensors (21) which deliver an analogue video signal (23) contg. pixel grey levels for digitisation (24). A microcontroller (26) operates on the image stored in memory (54) using a data bus (55) for the grey level ...

Le Gallo Yann, Albou Pierre: Method and apparatus for detecting fog or smoke, suitable for a vehicle. Valeo Vision, December 20, 1995: EP0687594-A1 (26 worldwide citation)

The method for detecting the presence of fog or smoke in the vicinity of a vehicle includes taking a photograph of the field of view, and analysing the contrast which exists in the picture (E). A signal (S), relative of the analyse result, is transmitted indicating fog detection. The image analysis ...

Robert Caroline, Albou Pierre, Leleve Joel: Process for modulated illumination of a road and headlamp using this process. Valeo Vision, May 2, 2007: EP1780462-A1 (20 worldwide citation)

The modular lighting procedure is effected by a headlight containing a number of separate light sources, such as LEDs, each producing a partial beam emitted in a predetermined direction. The partial beams overlap to create the full headlight beam, and one or more of the light sources can be modulate ...

Albou Pierre, de Lamberterie Antoine: Optical module for headlights of an automobile. Valeo Vision, January 23, 2008: EP1881264-A1 (16 worldwide citation)

The module (P) has an additional module (A) including a light source i.e. LED (9), and a lens (10) placed in front of the LED for producing a complementary beam which provides a full beam when combined with a slanted cut off beam i.e. fog-light beam. The module (A) includes a hyperbolic light-recove ...
