Abstract
An image sensing device includes a pixel array of a 4×4 pixel unit including first to fourth sub-pixel arrays of 2×2 pixels. The first and second sub-pixel arrays are arranged in a first diagonal direction, and the third and fourth sub-pixel arrays are arranged in a second diagonal direction intersecting the first diagonal direction. The first and second sub-pixel arrays have a first color pattern, and the third and fourth sub-pixel arrays have second and third color patterns, respectively, and each of the first to third color patterns includes two or more colors.

An image sensing device, comprising:
- a pixel array of a 4×4 pixel unit including first to fourth sub-pixel arrays of 2×2 sub-pixel arrays, the first and second sub-pixel arrays being arranged in a first diagonal direction, the third and fourth sub-pixel arrays being arranged in a second diagonal direction intersecting the first diagonal direction,
- wherein the first and second sub-pixel arrays have a first color pattern, the third sub-pixel array has a second color pattern, the fourth sub-pixel array has a third color pattern different from the second color pattern, and each of the first to third color patterns includes two or more colors,
- wherein a part of each of the second and third color patterns has a different color arrangement from the first color pattern.
An image sensing device, comprising:
- a pixel array including sub-pixel arrays arranged in i rows and j columns, in which Aij, Bij, Cij and Dij (where i and j are integers) pixels are arranged in 2×2 units, the Aij and Bij pixels and the Cij and Dij pixels are arranged adjacent to each other in a row direction, respectively, and the Aij and Cij pixels and the Bij and Dij pixels are arranged adjacent to each other in a column direction, respectively,
- wherein each of two pixels among the Aij, Bij, Cij and Dij pixels has a green color, and each of remaining two pixels has one or more colors other than the green color, and
- the remaining two pixels among the Aij, Bij, Cij and Dij pixels included in each of odd-numbered sub-pixel arrays and one of even-numbered sub-pixel arrays are disposed adjacent to each other in a diagonal direction and have the same color, and
- the remaining two pixels among the Aij, Bij, Cij and Dij pixels included in each of the remaining one of the odd-numbered sub-pixel arrays and the remaining one of the even-numbered sub-pixel arrays are disposed adjacent to each other in the diagonal direction and have different colors.
An image sensing device comprising an array of light-sensitive elements, the array includes:
- a first type of light-sensitive elements sensitive in a green region of a spectrum of the light, arranged at every other element position along both a vertical direction and a horizontal direction;
- and
- a second type of light-sensitive elements sensitive in a red region of a spectrum of the light and a third type of light-sensitive elements sensitive in a blue region of a spectrum of the light, each of the second and third type of light-sensitive elements being arranged at an element position surrounded by four light-sensitive elements of the first type,
- wherein a part of a color pattern of the second type of light-sensitive elements and a part of a color pattern of the third type of light-sensitive elements have different color arrangements from a color pattern of the first type of light-sensitive elements, and
- wherein a part of the array of the second and third types of light-sensitive elements is arranged such that the second and third types of light-sensitive elements are alternately arranged along a plurality of first diagonal lines, and the other part of the array of the second and third types of light-sensitive elements is arranged such that two consecutive second types of light-sensitive elements and two consecutive third types of light-sensitive elements are alternately arranged along a plurality of second diagonal lines, each of which is arranged between two adjacent first diagonal lines.
