Abstract: An image sensor includes: a substrate, having first and second surfaces opposing each other in a first direction, on which a plurality of unit pixels are arranged, the plurality of unit pixels including a normal pixel, an autofocusing pixel, and a compensation pixel in a direction, parallel to the first surface; a photodiode disposed in the substrate in each of the plurality of unit pixels; and a device isolation layer disposed between the plurality of unit pixels. The unit pixels include color filters, separated from each other by a grid, and microlenses disposed on the color filters. The compensation pixel is disposed on one side of the autofocusing pixel and includes a compensation microlens, smaller than a normal microlens included in the normal pixel, and a transparent color filter separated from adjacent color filters by a compensation grid smaller than a normal grid included in the normal pixel.
