    Abstract: An image sensor is provided. The image sensor image sensor includes: a first pixel group including a first pixel, a second pixel, a third pixel and a fourth pixel; a second pixel group including a fifth pixel, a sixth pixel, a seventh pixel and an eighth pixel, wherein the second pixel group is provided adjacent to the first pixel in a first direction; a first lens corresponding to the first pixel and the second pixel; a second lens corresponding to the third pixel and the fourth pixel; a device isolation pattern electrically isolating the first pixel group from the second pixel group; and a readout circuit configured to: output phase data based on at least a portion of phase signals received from the first pixel group; and output image data based on at least a portion of color signals received from the second pixel group.

    Abstract: A pixel array of an image sensor includes a plurality of pixel groups. Each pixel group includes a plurality of unit pixels adjacent to each other and respectively including photoelectric conversion elements disposed in a semiconductor substrate, a color filter shared by the plurality of unit pixels, and a plurality of microlenses disposed on the color filter and having sizes different from each other such that the plurality of microlenses respectively focus an incident light to the photoelectric conversion elements included in the plurality of unit pixels. Deviations of sensing sensitivity of unit pixels are reduced and quality of images captured by the image sensor is enhanced by adjusting sizes of microlenses.

    Abstract: An image sensor includes a normal pixel, a first auto-focus (AF) pixel, and a second AF pixel, each of the normal pixel, the first AF pixel and the second AF pixel including a photodiode. The image sensor further includes a normal microlens disposed on the normal pixel, and a first AF microlens disposed on the first AF pixel and the second AF pixel. The photodiode of the normal pixel, the photodiode of the first AF pixel, and the photodiode of the second AF pixel are respectively disposed in photo-detecting areas of a semiconductor substrate. A height of the first AF microlens in a vertical direction from a top surface of the semiconductor substrate is greater than a height of the normal microlens in the vertical direction from the top surface of the semiconductor substrate.

    Abstract: There is provided an image sensor including first to fourth color filter layers arranged on a substrate and first to seventh microlenses arranged on the first to fourth color filter layers. The first microlenses vertically overlap diagonal components of a first submatrix comprised of green-red subpixels. The second and third group of microlenses vertically overlap off-diagonal components of the first submatrix comprised of green-red subpixels. A horizontal area of each of the second group of microlenses is less than a horizontal area of each of the first microlenses and a horizontal area of each of the third group of microlenses is greater than a horizontal area of each of the first microlenses.
