Title (EN) ENDOSCOPIC IMAGING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ D'IMAGERIE ENDOSCOPIQUE
Abstract:
(EN) An endoscopic imaging apparatus comprises at least one light source (1, 2, 3) configured to provide excitation signals to an imaging region via a common transmission path. Each excitation signal has one of a plurality of different colours. A controller (100) is configured to control the at least one light source (1, 2, 3) to provide the excitation signals as a repeating time-interleaved sequence that comprises at least an excitation signal of a first one of the colours and a subsequent excitation signal of a second one of the colours. A monochrome detector (80) is configured, for each of at least some of the excitation signals, to receive at least part of a respective response signal emitted from the imaging region in response to the excitation signal and to generate image data based on the at least part of the response signal.
(FR) La présente invention concerne un appareil d'imagerie endoscopique comprenant au moins une source de lumière (1, 2, 3) configurée pour fournir des signaux d'excitation à une région d'imagerie par l'intermédiaire d'un trajet de transmission commun. Chaque signal d'excitation possède l'une d'une pluralité de différentes couleurs. Un dispositif de commande (100) est configuré pour commander ladite source de lumière (1, 2, 3) afin de fournir des signaux d'excitation sous la forme d'une séquence à entrelacement de temps de répétition qui comprend au moins un signal d'excitation d'une première des couleurs et un signal d'excitation ultérieur d'une seconde des couleurs. Un détecteur monochromique (80) est configuré, pour chacun d'au moins certains des signaux d'excitation, afin de recevoir au moins une partie du signal de réponse respectif émis depuis la région d'imagerie en réponse au signal d'excitation et pour générer les données d'image sur la base de la au moins une partie du signal de réponse.
