Abstract
The invention relates to an imager system comprising a main image sensor () and comprising a main matrix () of active pixels exhibiting a first instantaneous dynamic span of luminous sensitivity, and a main reading circuit adapted for reading the pixels of the main image sensor () and for acquiring a main image on the basis of said reading, an auxiliary image sensor () comprising a second matrix () of active pixels exhibiting a second instantaneous dynamic span of luminous sensitivity which is more extensive than the first instantaneous dynamic span of luminous sensitivity, and an auxiliary reading circuit adapted for reading the active pixels of the auxiliary image sensor () and for acquiring an auxiliary image on the basis of said reading, and a data processing unit () configured to determine at least one value of an acquisition parameter of the main image sensor on the basis of the auxiliary image.
