Abstract: An image sensor and an image capturing system are provided. The image sensor includes a pixel array, and the pixel array includes a plurality of image sensing arrays and a focus sensing pixel group. Each of the image sensing arrays is covered by a plurality of color filter units, and the focus sensing pixel group is not covered by the color filter units. The focus sensing pixel group includes a plurality of first focus sensing pixel units, and the first focus sensing pixel units are arranged according to a first arrangement pattern. An area ratio of the focus sensing pixel group and the pixel array is smaller than one-ninth, or the focus sensing pixel group is, with respect to the whole pixel array, non-uniformly disposed in the pixel array. The image capturing system of the present invention can enhance a focus function.
