An image sensor comprising:
- organic photodetectors;
- an angular filter less than 20 μm away from the photodetectors;
- and
- a surface intended to receive a radiation, said photodetectors being configured to detect said radiation, the angular filter covering the organic photodetectors and being configured to block the rays of said radiation having an incidence relative to a direction orthogonal to the surface greater than a threshold and to give way to rays of said radiation having an incidence relative to a direction orthogonal to the surface smaller than the threshold,
- wherein the angular filter comprises a layer opaque to said radiation and an array of openings formed in the layer, the openings being filled with air or with a material at least partially transparent to said radiation, and
- wherein the openings are arranged in rows and in columns, a pitch between adjacent openings of a same row or of a same column varying from 10 μm to 60 μm.
