Claim 11:
12. The apparatus of claim 11, wherein the first fine structure, the second fine structure, the third fine structure, and the fourth fine structure are configured such that, at a position immediately after passing through the color separation lens array,
the light of the first wavelength forms a phase distribution of 2Nπ at the first photo-sensing cells and the fourth photo-sensing cells and forms a phase distribution of (2N−1)π at the second photo-sensing cells and the third photo-sensing cells,
the light of the second wavelength forms a phase distribution of (2M−1)π at the first photo-sensing cells and the fourth photo-sensing cells, forms a phase distribution of 2Mπ at the second photo-sensing cells, and forms a phase distribution that is greater than (2M−2)π and less than (2M−1)π at the third photo-sensing cells, and
the light of the third wavelength forms a phase distribution of (2L−1)π at the first photo-sensing cells and the fourth photo-sensing cells, forms a phase distribution of 2Lπ at the third photo-sensing cells, and forms a phase distribution that is greater than (2L−2)π and less than (2L−1)π at f the second photo-sensing cells, wherein N, M, and L are integers greater than 0.
