1. An image sensor, comprising:
a pixel array including a plurality of normal pixels and a plurality of phase detection groups, wherein each phase detection group includes a first phase detection pixel and a second phase detection pixel disposed adjacent to the first phase detection pixel; and
a color filter array including a plurality of unit groups, wherein each unit group includes a plurality of color filters of a same color arranged in an M×N matrix on the pixel array,
wherein a first color filter among the color filters of a first color is disposed on the first phase detection pixel of one of the unit groups and a second color filter among the color filters of a second color different from the first color is disposed on the second phase detection pixel of another one of the unit groups,
wherein M and N are natural numbers,
wherein a first side of the first phase detection pixel is adjacent a first one of the normal pixels with the first color filter in a first column,
wherein a second side of the first phase detection pixel opposing the first side is adjacent a second one of the normal pixels with the first color filter in the first column,
wherein a first side of the second phase detection pixel is adjacent a first one of the normal pixels with the second color filter in a second column, and
wherein a second side of the second phase detection pixel is adjacent a second one of the normal pixels with the second color filter in the second column.
