Publication number: 20230400297Abstract: A camera module is manufactured by attaching a lens module to an image sensor. The lens module includes at least one lens element which has a plurality of centers of curvature. A tilt angle of an imaging axis of the image sensor is determined, and a tilt angle of an optical axis of the lens module is also determined by using an optical device to identify locations of multiple centers of curvature of the at least one lens element included in the lens module. At least one of the lens module and the image sensor are then adjusted accordingly so that the imaging axis and the optical axis are aligned, and thereafter, the lens module is fixedly attached with respect to the image sensor to form the camera module.Type: ApplicationFiled: May 20, 2022Publication date: December 14, 2023Inventors: Ying San CHUI, Kwok Yuen CHEUNG, Hei Lam CHANG, Man Wai CHAN, Po Lam AU
