Title (EN) IMAGING DEVICE WITH AN IMPROVED AUTOFOCUSING PERFORMANCE
(FR) DISPOSITIF D'IMAGERIE À PERFORMANCE DE MISE AU POINT AUTOMATIQUE AMÉLIORÉE
Abstract:
(EN) The invention describes an imaging device (1) comprising an image sensor (2), an imaging lens (3), an infrared light source (5) to illuminate a scene (SC), and an infrared autofocus system (6) for providing an autofocus function, wherein the image sensor (2) comprises an array (21) of sensor pixels each arranged as dual pixel (22) comprising two separate pixel sensors (22a, 22b) per dual pixel (22) to record the image data (D1) as a sum signal from both pixel sensors (22a, 22b) and providing infrared data (D2) as individual signals from each of the two pixel sensors (22a, 22b) for phase contrast (PC) autofocusing, wherein an infrared filter (7) arranged between an aperture (4) of the imaging device (1) and an imaging sensor (2) and is adapted to locally transmit only a portion of the infrared light (IR) to the imaging sensor (2) by comprising at least one first area (71) arranged as infrared blocking area and at least one second area (72) arranged as infrared bandpass area. The invention further relates to a method (100) to automatically focusing this device (1)
(FR) L'invention concerne un dispositif d'imagerie (1) qui comprend un capteur d'image (2), une lentille d'imagerie (3), une source de lumière infrarouge (5) destinée à éclairer une scène (SC) et un système de mise au point automatique infrarouge (6) destiné à fournir une fonction de mise au point automatique. Le capteur d'image (2) comprend un réseau (21) de pixels de capteur disposés chacun sous la forme d'un double pixel (22) qui comprend deux capteurs de pixel séparés (22a, 22b) par double pixel (22) destinés à enregistrer les données d'image (D1) en tant que signal de somme des deux capteurs de pixel (22a, 22b) et destinés à fournir des données infrarouges (D2) en tant que signaux individuels de chacun des deux capteurs de pixel (22a, 22b) en vue d'une mise au point automatique par contraste de phase (PC). Un filtre infrarouge (7) est disposé entre une ouverture (4) du dispositif d'imagerie (1) et un capteur d'imagerie (2) et est apte à transmettre localement uniquement une partie de la lumière infrarouge (IR) au capteur d'imagerie (2) à l'aide d'au moins une première zone (71) conçue en tant que zone de blocage infrarouge et au moins une seconde zone (72) conçue sous la forme d'une zone de bande passante infrarouge. L'invention concerne en outre un procédé (100) de mise au point automatique de ce dispositif.
