  • Publication number: 20240094507
    Abstract: An optical imaging system includes a first lens having positive refractive power, a convex object-side surface and a concave image-side surface; a second lens having negative refractive power, a convex object-side surface and a concave image-side surface; a third lens having positive refractive power; a fourth lens having negative refractive power; a fifth lens; a sixth lens having a convex object-side surface; and a seventh lens having negative refractive power, a convex object-side surface and a concave image-side surface, wherein the first to seventh lenses are disposed in order from an object side toward an imaging plane, wherein the optical imaging system has a total of seven lenses, and wherein 0<f1/f<1.5, ?5<f2/f<?1, ?10<f3/f/100<2, ?5<f4/f/100<1, ?0.5<f1/f2<0, ?1<f1/f3<3, 70°<FOV×(IMG HT/f), and |f1/f4/n4|<0.3 are satisfied.

  • Publication number: 20240085668
    Abstract: An optical imaging system includes a first lens having positive refractive power, a second lens having negative refractive power, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens disposed in order from an object side. A refractive index of the second lens is greater than a refractive index of each of the first lens and the third lens. The optical imaging system satisfies TTL/(2×IMG HT)<0.6 and 0<f1/f<1.4, where TTL is a distance on an optical axis from an object-side surface of the first lens to an imaging plane, IMG HT is half a diagonal length of the imaging plane, f is a total focal length of the optical imaging system, and f1 is a focal length of the first lens.

  • Patent number: 10477082
    Abstract: An electronic device is provided. The electronic device includes a housing including a front plate, a back plate, and a side member surrounding a space between the front plate and the back plate. The side member includes a plurality of non-conductive portions and a conductive portion. The electronic device also includes a display module, and at least one wireless communication circuit. The electronic device also includes a printed circuit board (PCB). The camera assembly is exposed through a portion of the back plate. The camera assembly includes an image sensor mounted on the PCB, and a plurality of lenses. The camera assembly also includes a barrel that surrounds the plurality of lenses, and a camera bracket that surrounds at least part of the barrel. The camera assembly also includes a metal case that surrounds at least part of the camera assembly, and a shielding structure.
