Title (DE) VORRICHTUNG UND VERFAHREN ZUR BILDERZEUGUNG
(EN) DEVICE AND METHOD FOR PRODUCING IMAGES
(FR) DISPOSITIF ET PROCEDE DE PRODUCTION D'IMAGES
Abstract:
(DE) Es wird eine Vorrichtung und ein Verfahren zur Bilderzeugung in einem Kraftfahrzeug vorgeschlagen. Eine infrarotempfindliche Kamera erzeugt Bilder von der Umgebung des Kraftfahrzeuges. Zur gepulsten Ausleuchtung von Teilbereichen des Bilderfassungsbereiches der Kamera wird eine im nahen infraroten Spektralbereich strahlende Strahlungsquelle verwendet. Die Kamera erzeugt die Bilder durch Erfassung von Teilbildbereichen. Zur Erfassung der Teilbildbereiche wird eine zeitliche Synchronisation mit der gepulsten Ausleuchtung des wenigstens den Teilbildbereich umfassenden Teilbereichs durchgeführt. Im bevorzugten Ausführungsbeispiel wird die Erfassung von Teilbildbereichen einer infrarotempfindliche CMOS-Kamera mit einem im nahen infraroten Spektralbereich strahlenden Laserdiode-Array zeitlich synchronisiert.
(EN) The invention relates to a device and a method for producing images in a motor vehicle. An infrared sensitive camera produces the images of the vehicle environment. A source emitting radiation in the near infrared spectral range is used for pulsed lighting of the partial image capture areas of the camera. Said camera produces images by capturing the partial areas of the coded image space thereof. A temporal synchronisation by the pulsed lighting of the partial area containing the partial image space is carried out for capturing the partial image storage space. In the preferred embodiment of said invention, the capturing of the partial image areas of a CMOS camera which is infrared sensitive is temporally synchronised with the aid of a laser diode assembly which emits in the near infrared spectral range.
(FR) Dispositif et procédé de production d'images dans un véhicule à moteur. Une caméra sensible aux infrarouges produit des images de l'environnement du véhicule. Une source de rayonnement émettant dans la plage spectrale de l'infrarouge proche est utilisée pour un éclairage pulsé de zones partielles de la région de saisie d'images de la caméra. La caméra produit les images par saisie de zones d'image partielles. Une synchronisation temporelle avec l'éclairage pulsé de la zone partielle comportant la zone d'image partielle est effectuée en vue de la saisie des zones d'image partielles. Dans le mode de réalisation préféré de la présente invention, la saisie de zones d'image partielles d'une caméra CMOS sensible aux infrarouges est synchronisée temporellement à l'aide d'un ensemble de diodes laser émettant dans la plage spectrale des infrarouges proches.
