IMAGING SYSTEM, CAMERA MODULE, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/198498

A1

The present application discloses an imaging system, a camera module, and an electronic device. The imaging system comprises, in order from the object side to the image side along an optical axis: a diagram; a first lens having positive refractive power, the object side surface of the first lens close to the optical axis being a convex surface; a second lens having negative refractive power, the image side surface of the second lens close to the optical axis being a concave surface; a third lens having refractive power; a fourth lens having positive refractive power, the image side surface of the fourth lens close to the optical axis being a convex surface; and a fifth lens having negative refractive power, an object side surface of the fifth lens close to the optical axis being a concave surface, and the image side surface of the fifth lens close to the optical axis being a concave surface. The imaging system satisfies the following conditional expression: 0
