Abstract: An image sensor may include a substrate which includes a plurality of block regions. Each block region may include a separate plurality of pixel regions. Each pixel region may include a separate photoelectric element of a plurality of photoelectric elements in the substrate and a separate micro lens of a plurality of micro lenses on the substrate. Each micro lens of the plurality of micro lenses may be laterally offset from a vertical centerline of the pixel region towards a center of the block region. Each block region of the plurality of block regions may include a common shifted shape of the plurality of micro lenses of the block region.

Abstract: An electronic device may include a photoelectric element, a shielding layer on the photoelectric element, and a color filter structure on the shielding layer. The shielding layer may define a first opening over the photoelectric element. The color filter structure may define a second opening over the photoelectric element and the first opening. The color filter structure may appear dark from a view facing the color filter structure.

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.
