1. A camera device comprising:
a plurality of lenses; and
an annular body;
wherein the plurality of lenses and the annular body are arranged between an object side and an image side along an optical axis;
wherein 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;
wherein the annular body comprises 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;
wherein a shape of the inner circumferential portion is the same as that of the outer circumferential portion;
wherein the camera device satisfies
Dx>Dy;
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;
wherein a horizontal interval and a vertical interval are defined between the outer circumferential portion and the inner circumferential portion, and a ratio of the horizontal interval to the vertical interval is between 1.1 and 27.6.
