Title:
IMAGING LENS ASSEMBLY, CAMERA MODULE, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/020893
Kind Code:
A1
Abstract:
An imaging lens assembly (2), a camera module (11), and an imaging device (1) are provided. The imaging lens assembly (2) includes an optical system including: in order from an object side to an image side, two aperture diaphragms of an adjustable diaphragm (1a) and an aperture diaphragm (1b), a diameter of the adjustable diaphragm (1a) not regulating a maximum diameter and a diameter of the aperture diaphragm (1b) regulating the maximum diameter, and eight lenses. The eight lenses of the optical system include in order from the object side, a first lens (L1) that has positive refractive power and whose object-side surface has a convex shape and image-side surface has a concave shape near a paraxial area; a second lens (L2) that has negative refractive power; a third lens (L3) that has positive refractive power; a fourth lens (L4); a fifth lens (L5); a sixth lens (L6); a seventh lens (L7); and an eighth lens (L8) that has negative refractive power and whose image-side surface has a concave shape. The imaging lens assembly (2) satisfies the following conditional expressions: Fno_min<2.4; HFOV>30, FL/Fno_min/((18*FL/ImgH*21.63)/FL-1)>0.085; and FL/Fno_max/((18*FL/ImgH*21.63)/FL-1)<0.080. The imaging lens assembly (2), the camera module (11), and the imaging device (1) can obtain a sufficient backgroud blur effect while maintaining an image quality and a resolution.
