Abstract
(EN) An embodiment of an autofocus system (100, 400) is configured to receive a first signal (102a, 402a) corresponding to a first wavelength range and to receive a second signal (102b, 402b) corresponding to a second wavelength range. The autofocus system (100, 400) is further con-5 figured to determine an output signal (106, 406) comprising a focus setting information using the first signal (102a, 402a) and the second signal (102b, 402b).
(FR) Un mode de réalisation d'un système de mise au point automatique (100, 400) est configuré pour recevoir un premier signal (102a, 402a) correspondant à une première plage de longueurs d'onde et pour recevoir un second signal (102b, 402b) correspondant à une seconde plage de longueurs d'onde. Le système de mise au point automatique (100, 400) est en outre conçu pour déterminer un signal de sortie (106, 406) comprenant des informations de réglage de mise au point utilisant le premier signal (102a, 402a) et le second signal (102b, 402b).
