Patent ID: 8902339

Claim:
A solid-state image sensor comprising: a photosensitive cell array, in which a number of unit blocks are arranged two-dimensionally, each said unit block including first, second, third and fourth photosensitive cells, a dispersing element array that is arranged so as to face the photosensitive cell array and that includes a plurality of dispersing elements, wherein light that would have been directly incident on each said photosensitive cell if not for the dispersing element array is called that photosensitive cell's entering light, and the dispersing element array is configured to: direct a light ray with a first color component from the first photosensitive cell's entering light such that the light ray with the first color component is not incident on the first photosensitive cell, direct a light ray with a second color component from the entering light of the second photosensitive cell to be incident on the first photosensitive cell along with a remainder of the first photosensitive cell's entering light, direct a light ray with a second color component from the second photosensitive cell's entering light such that the light ray with the second color component is not incident on the second photosensitive cell, direct a light ray with the first color component from the entering light of the first photosensitive cell to be incident on the second photosensitive cell along with a remainder of the second photosensitive cell's entering light, direct a light ray with a third color component from the third photosensitive cell's entering light such that the light ray with the third color component is not incident on the third photosensitive cell, direct light rays with the first and second color components from the entering light of the fourth photosensitive cell to be incident on the third photosensitive cell along with a remainder of the third photosensitive cell's entering light, and direct light rays with the first and second color components from the fourth photosensitive cell's entering light such that the light rays with the first and second color components are not incident on the fourth photosensitive cell, direct a light ray with the third color component from the entering light of the third photosensitive cell to be incident on the fourth photosensitive cell along with a remainder of the fourth photosensitive cell's entering light.
