Optical imaging module and device and electronic device

Abstract

The present disclosure provides an optical imaging module, an optical imaging device and an electronic device. The optical imaging module includes a first lens group and a second lens group arranged in sequence from an object side to an imaging surface. The first lens group has a positive refractive power, and includes a first lens having a positive refractive power and a second lens having a negative refractive power arranged in sequence from the object side to the imaging surface. The first lens includes a convex object-side surface and a convex image-side surface. The second lens group includes a plurality of lenses with refractive power, and the plurality of lenses with refractive power include at least one movable lens configured to focus on objects to be photographed at different distances by moving along the optical axis.
