Abstract
(EN)
An imaging system that has a camera unit and a control unit. A control signal transmission circuit of the control unit sets the bias potential of a signal line at one of two or more different potentials at timing that has been set on the basis of a first video synchronization signal and thereby outputs a control signal that indicates imaging conditions for an image sensor to the signal line. A signal processing circuit of the camera unit receives the control signal and, by detecting the bias potential at timing that has been set on the basis of a second video synchronization signal, detects the imaging conditions from the control signal.
(FR)
L'invention concerne un système d'imagerie comprenant une unité caméra et une unité de commande. Un circuit de transmission de signal de commande de l'unité de commande définit le potentiel de polarisation d'une ligne de signal à l'un d'au moins deux potentiels différents à l'instant qui a été défini sur la base d'un premier signal de synchronisation vidéo, et délivre ainsi un signal de commande qui indique des conditions d'imagerie pour un capteur d'image à la ligne de signal. Un circuit de traitement de signal de l'unité caméra reçoit le signal de commande et, via la détection du potentiel de polarisation à l'instant qui a été défini sur la base d'un second signal de synchronisation vidéo, détecte les conditions d'imagerie à partir du signal de commande.
