Claim 7:
8. An image sensing method for acquiring color information from incoming visible light using an image sensor comprising three pixels being partially covered by a color splitter structure, the method comprising deviating only one color channel of said incoming visible light towards one of said three pixels, and deviating other colors of said incoming visible light towards the other pixels among said three pixels, wherein the color splitter structure comprises a first, a second and a third parallelepiped structures arranged so that the first and the third parallelepiped structures are side by side and in contact with the second parallelepiped structure, and wherein the first and the third parallelepiped structures have same dimensions, and are made of a same dielectric material, with a refractive index nH, and wherein said second parallelepiped structure being smaller in height compared to said first and third parallelepiped structures, and wherein said second parallelepiped structure being made of a dielectric material with a refractive index nL.
