Claim 13:
14. The apparatus of claim 13, wherein the first structure to the fourth 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 first phase distribution of 2Nπ at central portions of the plurality of first photo-sensing cells and central portions of the plurality of fourth photo-sensing cells and forms a second phase distribution of (2N−1)π at central portions of the plurality of second photo-sensing cells and central portions of the plurality of third photo-sensing cells, the light of the second wavelength forms a third phase distribution of (2M−1)π at the central portions of the plurality of first photo-sensing cells and the central portions of the plurality of fourth photo-sensing cells, forms a fourth phase distribution of 2Mπ at the central portions of the plurality of second photo-sensing cells, and forms a fifth phase distribution that is greater than (2M−2)π and less than (2M−1)π at the central portions of the plurality of third photo-sensing cells, and
the light of the third wavelength forms a sixth phase distribution of (2L−1)π at the central portions of the plurality of first photo-sensing cells and the central portions of the plurality of fourth photo-sensing cells, forms a seventh phase distribution of 2Lπ at the central portions of the plurality of third photo-sensing cells, and forms an eighth phase distribution that is greater than (2L−2)π and less than (2L−1)π at the central portions of the plurality of second photo-sensing cells, wherein N, M, and L are integers greater than 0.
