The invention relates to electronic cameras for portraying illuminated images. The camera comprises an electronic image sensor (42), with an active face (79) of photosensitive pixels forming a photosensitive surface (44), electrical conductors on the active face and a free face (102), opposite the active face and an optical set (46), comprising at least one focussing lens (52) for focussing illuminated images on the photosensitive surface of the sensor. The optical set of the camera is mechanically fixed to the sensor and, in order to assure a central focussing of the illuminated images on the photosensitive surface of the sensor, at least two positioning surfaces on the optical set (72, 74) and the sensors (79) are in direct mechanical contact. Applications: low-cost electronic cameras for micro-computers, portable telephones and digital cameras.
L'invention concerne les caméras électroniques de visualisation d'images lumineuses. La caméra (40) comporte un capteur électronique (42) d'images ayant une face active (79) ayant un arrangement de pixels photosensibles formant une surface photosensible (44), des conducteurs électriques sur la face active et une face libre (102) opposée à la face active, un bloc optique (46) comportant au moins une lentille de focalisation (52) des images lumineuses sur la surface photosensible du capteur. Le bloc optique de la caméra est solidaire mécaniquement du capteur et pour assurer une focalisation centrée des images lumineuses sur la surface photosensible du capteur, au moins deux surfaces de positionnement du bloc optique (72, 74) et du capteur (79) sont en contact mécanique direct. Applications: caméras électroniques à faible coût pour micro-ordinateur, téléphones portables appareils photo- numériques.
