Abstract: The invention relates to a system suitable for providing an operator with enhanced visibility, useful in particular to aid aircraft piloting, comprising at least one sensor able to capture image data in a given spectral band and a central calculation unit able to process the image data captured and to transmit them to a display unit. This system comprises: at least one high-resolution sensor (20) able to acquire image data forming a digital image (I0) in a spectral band including at least all or some of the spectral band visible to the human eye, of first spatial resolution, and of strictly finer angular capture resolution than the angular resolution of the human eye, and a nonlinear processing module (22) adapted to produce a change in spatial resolution while preserving bright points of said digital image acquired (I0) so as to obtain a digital image (I1) to be displayed of second spatial resolution lower than the first spatial resolution.
