SENSOR SYSTEMS AND DIGITAL CAMERAS

摘要

A camera (150) has a sensor (160) which is non-planar. The sensor comprises a plurality of planar facets (162) which form an array having a curvilinear configuration, facets in a central region having a greater pixel density than facets nearer the edge of the array. The camera has movable shade elements (184, 186) which shade the lens from extraneous light and which can be extended in dependence upon the angle of view. To compensate for gaps (164) between the facets (162), a composite image is formed from two successive exposures; a mechanism (190) is provided for tilting the lens between the exposures.
