Classification: CPC H  G | IPC G  H

Claim 16:
17. An electronic device, comprising:
a housing; and
an imaging module mounted on the housing, the imaging module comprising:
an optical imaging device, from an object side to an image side, comprising:
a first lens having a refractive power;
a second lens having a refractive power;
a third lens having a refractive power;
a fourth lens having a negative refractive power, wherein an image-side surface of the fourth lens is convex near an optical axis of the optical imaging device; and
a fifth lens having a negative refractive power, wherein an image-side surface of the fifth lens is concave near the optical axis; and

an optical sensor arranged on the image side of the optical imaging device;

wherein the optical imaging device satisfies the following formulas:

0.03 mm/°<TL5/FOV<0.1 mm/° and 2.4 mm<TL4/FNO<2.9 mm;

wherein, TL5 is a distance from an object-side surface of the fifth lens to an image plane of the optical imaging device along the optical axis, FOV is a maximum field of view of the optical imaging device, TL4 is a distance from an object-side surface of the fourth lens to the image plane along the optical axis, FNO is a F-number of the optical imaging device.
