Abstract
A camera device includes a plurality of lenses and an annular body. The annular body is disposed between the object side and the plurality of lenses, between the plurality of lenses, or between the plurality of lenses and the image side. The annular body includes an annular main body, an outer circumferential portion, and an inner circumferential portion, wherein the annular main body connects to the outer circumferential portion and the inner circumferential portion, the annular main body is disposed between the outer circumferential portion and the inner circumferential portion, and the inner circumferential portion is non-circular and surrounds the optical axis to form a hole. The camera device satisfies: Dx>Dy, 1<Dx/Dy<28, where Dx is a maximum dimension of the hole through which the optical axis passes, and Dy is a minimum dimension of the hole through which the optical axis passes.
