Abstract: An image sensor includes different first and second focus pixels in a substrate; a first adjacent pixel in the substrate and adjacent to the first focus pixel in a positive first direction, a pixel being absent between the first focus pixel and the first adjacent pixel; a first micro-lens covering the first adjacent pixel; a second adjacent pixel in the substrate and adjacent to the second focus pixel in a positive first direction, a pixel being absent between the second focus pixel and the second adjacent pixel; and a second micro-lens covering the second adjacent pixel, and an area of the first micro-lens being different from an area of the second micro-lens.

Abstract: An image sensor that provides a uniform sensitivity for pixels having color filters of the same color to increase the image quality is provided. The image sensor includes a substrate, a first grid pattern disposed on the substrate and including a first side wall and a second side wall opposite to the first side wall, a first pixel including a first photoelectric conversion element and a first color filter, and a second pixel including a second photoelectric conversion element and a second color filter. The first color filter contacts the first side wall and the second color filter contacts the second side wall. The first color filter and the second color filter are color filters of same color, and a first thickness of the first color filter is greater than a second thickness of the second color filter.

Abstract: An image sensor includes two or more phase-difference detection pixels disposed adjacent to each other, a plurality of general pixels spaced apart from the phase-difference detection pixels, first and second peripheral pixels, and first to third light shields. The first and second peripheral pixels are adjacent to the phase-difference detection pixels, and between the phase-difference detection pixels and the general pixels. The first light shield is disposed in one of the general pixels and has a first width. The second light shield extends into the first peripheral pixel from a first area between the phase-difference detection pixels and the first peripheral pixel, and has a second width different from the first width. The third light shield extends into the second peripheral pixel from a second area between the phase-difference detection pixels and the second peripheral pixel, and has a third width different from the first width.
