Patent ID: 8514319

Claim:
A solid-state image sensor comprising: a photosensitive cell array in which a plurality of unit blocks, each including eight photosensitive cells that are arranged in four rows and two columns, are arranged in a matrix pattern; and a dispersing element array being arranged to face the photosensitive cell array and including a first dispersing element that is arranged to face a photosensitive cell that is located at a row 1 , column 2 position, a second dispersing element that is arranged to face a photosensitive cell that is located at a row 2 , column 1 position, a third dispersing element that is arranged to face a photosensitive cell that is located at a row 3 , column 1 position, and a fourth dispersing element that is arranged to face a photosensitive cell that is located at a row 4 , column 1 position, wherein the first dispersing element makes a light ray with a first color component incident on a photosensitive cell at a row 1 , column 1 position and makes the rest of incoming light other than the light ray with the first color component incident on the photosensitive cell at the row 1 , column 2 position, and wherein the second dispersing element makes a light ray with a second color component incident on a photosensitive cell at a row 2 , column 2 position and makes the rest of the incoming light other than the light ray with the second color component incident on the photosensitive cell at the row 2 , column 1 position, and wherein the third dispersing element makes the light ray with the first color component incident on a photosensitive cell at a row 3 , column 2 position and makes the rest of the incoming light other than the light ray with the first color component incident on the photosensitive cell at the row 3 , column 1 position, and wherein the fourth dispersing element makes the light ray with the second color component incident on a photosensitive cell at a row 4 , column 2 position and also makes the rest of the incoming light other than the light ray with the second color component incident on the photosensitive cell at the row 4 , column 1 position.
