Zusammenfassung:	A device and method for generating updated camera-projector correspondences from a reduced set of test patterns (221, 222) is provided. When predetermined correspondences (230) between projector points (proji) and camera points (cami) in an initial relative position of a projector (207) and a camera (208) have been previously determined, a recalibration therebetween may occur by projecting a single test pattern (222) derived from the predetermined correspondences (230) to estimate movement therebetween. When the movement is too great to be estimated by a single test pattern, another test pattern (221) may be projected to determine an estimation function for the movement and in particular, estimate movement of one or more camera points in the projected images due to relative movement of the projector (207) and the camera (208) from the initial relative position to a current relative position.
