Title
(EN) CLOSED-LOOP CONTROL OF ILLUMINATION IN AN ENDOSCOPIC CAMERA SYSTEM
(FR) COMMANDE D'ÉCLAIRAGE EN BOUCLE FERMÉE DANS UN SYSTÈME DE CAMÉRA ENDOSCOPIQUE
Abstract
(EN)
An illumination source may be coupled to an image capture device through a connector. A light sensor is placed downstream of the connector to measure the light received by the image capture device from the illumination source. The light sensor provides the measurement of the received light to the illumination source for closed-loop control of illumination source. The light sensor may be positioned in a camera housing to take into account light attenuation from the illumination source to the camera. The light sensor may be positioned at other locations on the image capture device. Multiple light sensors may be positioned at different locations on the image capture device to detect sources or locations of attenuation. Redundant light sensors of more than one type of sensor may be used at a single light sensor location to provide for validation of measurements and increase the variety of information measured.

Selon l'invention, une source d'éclairage peut être couplée à un dispositif de capture d'image par l'intermédiaire d'un connecteur. Un capteur de lumière est placé en aval du connecteur pour mesurer la lumière reçue par le dispositif de capture d'image en provenance de la source d'éclairage. Le capteur de lumière fournit la mesure de la lumière reçue à la source d'éclairage pour une commande en boucle fermée de la source d'éclairage. Le capteur de lumière peut être positionné dans un boîtier de caméra pour prendre en considération l'atténuation de la lumière de la source d'éclairage à la caméra. Le capteur de lumière peut être positionné à d'autres emplacements sur le dispositif de capture d'image. De multiples capteurs de lumière peuvent être positionnés à différents emplacements sur le dispositif de capture d'image pour détecter des sources ou des emplacements d'atténuation. Des capteurs de lumière redondants d'au moins deux types de capteur peuvent être utilisés à un même emplacement de capteur de lumière pour assurer une validation de mesures et augmenter la diversité des informations mesurées.
