Abstract
An image sensor includes a substrate, transparent layers covering the substrate and delimiting an exposition surface exposed to light, separate photosensitive areas at the substrate level and, for each photosensitive area, a first optical means capable of deviating towards the photosensitive area light reaching a central region of a portion of the exposition surface. The sensor further includes, for each photosensitive area, a second optical means, separate from the first optical means, capable of deviating towards the photosensitive area light reaching a peripheral region of the portion of the exposition surface surrounding the central region.
