Abstract
L'invention concerne un dispositif d'imagerie (100) comprenant : - un capteur d'images (130), - une lentille, optiquement associée au capteur d'images (130), - un module de commande (120) conçu pour déclencher une pluralité de prises de vues par le capteur d'images (130), à des instants successifs, pour acquérir une pluralité respective d'images ayant une résolution spatiale donnée, et - un module d'analyse (126) conçu pour produire, par combinaison numérique des images acquises, une image super-résolue présentant une résolution spatiale supérieure à ladite résolution spatiale donnée. Selon l'invention : - ladite lentille est une lentille liquide (110) présentant un dioptre déformable (111) dont l'orientation moyenne est commandable, et - le module de commande (120) est conçu en outre pour commander ce dioptre déformable (111) à des orientations moyennes distinctes à chacun desdits instants successifs. Un véhicule (200) automobile équipé d'un tel dispositif d'imagerie (100), et un procédé associé sont également décrits.The invention relates to an imaging device (100) comprising: - an image sensor (130), - a lens, optically associated with the image sensor (130), - a control module (120) designed to trigger a plurality of shots by the image sensor (130), at successive instants, for acquiring a respective plurality of images having a given spatial resolution, and - an analysis module (126) designed to produce, by digital combination of the acquired images, a super-resolved image having a spatial resolution greater than said given spatial resolution. According to the invention: - said lens is a liquid lens (110) having a deformable diopter (111) whose mean orientation is controllable, and - the control module (120) is further designed to control this deformable diopter (111 ) at different average orientations at each of said successive instants. A motor vehicle (200) equipped with such an imaging device (100), and an associated method are also described.
