A camera device comprises a first detector having opto-electronic sensors for enabling an entire image to be input simultaneously, and associated with an optical system of long focal length. A second detector is associated with an optical system that gives a large field of view, covering the field of the first detector and extending beyond it. The camera device also includes means for synchronizing the images taken by the two detectors and for recording them.

A camera device for use on an airborne platform to provide recordable high-resolution images of a scene in the form of a strip that is elongated in a travel direction of the platform, said camera device comprising: first detector means arranged for being securely connected on the platform, including a first detector having a two dimensional matrix of opto-electronic sensors and a first optical system of long focal length forming an image of a zone of said scene on said first detector which is arranged to acquire all points of said image simultaneously and to deliver a signal representing said image as a full frame on an output thereof; second detector means arranged for being securely connected to the platform, including a second detector having a two dimensional matrix of opto-electronic sensors and a second optical system, having a short focal length as compared with the focal length of said first optical system, forming an image on said second detector which is arranged to deliver a signal representing the image formed on said second detector; means for synchronizing times at which images are simultaneous taken by the two detector means and for recording the signals representing the images, said times being sufficiently close to each other for two successive images from said first detector means to overlap mutually; optical scanning means optically associated with said first detector means for scanning transversely to said travel direction, arranged for directing a field of view of said first detector means into a plurality of successive directions for scanning transversely to said travel direction, said successive directions being such that different zones of the scene each in the field of view of said first detector in a respective one of said successive directions overlap partially and are all within the field of view of said second detector; and image processing means for mutually repositioning said images formed by said first detector means and providing a two dimensional mosaic of images.
