Abstract

Disclosed is an image sensor including a pixel array, wherein the pixel array includes a first sub-pixel array including pixels disposed in a first diagonal direction and each having a green filter, and pixels disposed in a second diagonal direction and each having a yellow filter; a second sub-pixel array including pixels disposed in the first diagonal direction and each having the green filter, and pixels disposed in the second diagonal direction and each having the yellow filter; a third sub-pixel array including pixels disposed in the second diagonal direction and each having a red filter, and pixels disposed in the first diagonal direction and each having a magenta filter; and a fourth sub-pixel array including pixels disposed in the second diagonal direction and each having a blue filter, and pixels disposed in the first diagonal direction and each having a cyan filter.

Dependent claims

An image sensor comprising:

a pixel array having a 4×4 unit pixel structure,
wherein the pixel array includes:
a first sub-pixel array including first and second pixels disposed in a first diagonal direction and each having a green filter, and third and fourth pixels disposed in a second diagonal direction and each having a yellow filter, the first and second diagonal directions intersecting each other;
a second sub-pixel array including fifth and sixth pixels disposed in the first diagonal direction and each having the green filter, and seventh and eighth pixels disposed in the second diagonal direction and each having the yellow filter;
a third sub-pixel array including ninth and 10th pixels disposed in the second diagonal direction and each having a red filter, and 11th and 12th pixels disposed in the first diagonal direction and each having a magenta filter;
and
a fourth sub-pixel array including 13th and 14th pixels disposed in the second diagonal direction and each having a blue filter, and 15th and 16th pixels disposed in the first diagonal direction and each having a cyan filter.

4 more elements

An image sensor comprising:

a pixel array including N×M pixels, where N and M are natural numbers greater than 2,
wherein the pixel array includes:
first pixels disposed along a first diagonal line and each having a green filter;
at least one second pixel having a yellow filter, at least one third pixel having a red filter and at least one fourth pixel having a blue filter, the second to fourth pixels being disposed along a second diagonal line parallel to the first diagonal line;
at least one fifth pixel having a magenta filter and at least one sixth pixel having a cyan filter, the fifth and sixth pixels being disposed along a third diagonal line parallel to the second diagonal line;
and
at least one seventh pixel having the yellow filter, at least one eighth pixel having the red filter and at least one ninth pixel having the blue filter, the seventh to ninth pixels being disposed along a fourth diagonal line parallel to the third diagonal line.
