Title:
IMAGING LENS ASSEMBLY WHICH TAKES INTO CONSIDERATION IMAGE PROCESSING-BASED DISTORTION CORRECTION, CAMERA MODULE AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/109795
Kind Code:
A1
Abstract:
An imaging lens assembly includes at least one lens having a positive refractive power, and at least one lens having a negative refractive power, wherein the imaging lens assembly satisfies the following conditional expressions, (ΣD / Ymax) × (Fno + 1.8) ≤ 5.4, Dist1.0_10cm /Dist 0.7_10cm >0.95, where ΣD is a full length of the imaging lens assembly, Ymax is a maximum image height, Fno is an F number, Dist 1.0_10cm is a distortion amount before image processing-based distortion correction is performed, the distortion amount being obtained in an image height of 100%of the maximum image height when an object distance, which is a distance between the object and a most object side disposed lens, is 10 cm, and Dist0.7_10cm is a distortion amount before image processing-based distortion correction is performed, the distortion amount being obtained in an image height of 70% of the maximum image height when the object distance is 10 cm.
