Abstract

The invention provides a camera module array. The system comprises at least two camera modules, wherein at least one camera module is provided with a free-form surface lens, and the free-form surfacelens performs active calibration according to the actual imaging result received by the photosensitive chip, so that the difference between the actual reference direction of the free-form surface lensand the reference direction determined by the optical design is not greater than 0.05 degree. The invention further provides a corresponding camera module array assembling method. The TTL of the camera module can be reduced through the free-form surface lens, for example, the TTL of the wide-angle module and the TTL of the long-focus module are equal or close to each other, and then the double-camera module composed of the wide angle and the long focus can be easily installed in a mobile phone and other pieces of terminal equipment. The installation precision of the free-form surface lens canbe effectively improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular, the invention relates to a camera module array and an assembly method thereof. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In order to meet more and more extensive market demands, high pixel, small size, and large aperture are irreversible development trends of existing camera modules. A large aperture lens can bring a large field of view, however, this also leads to the problems of longer optical length of the lens and larger distortion of the field of view. For example, for a mobile phone lens with a 130°...
