Both of the above schemes have corresponding drawbacks. First, need additionally increase a camera, like this, can increase the occupation rate to cell-phone inner space, can increase the manufacturing cost of cell-phone, and this microspur camera is small, and camera pixel is lower relatively. The second scheme is limited by the performance of the camera, a series of algorithm processing is often needed to obtain the poor and pleasant shooting effect, so that the internal accommodating space of the mobile phone is wasted, the cost is increased, and the micro-distance shooting effect is not influenced yet.

The camera module 100 and the electronic device 300 according to the embodiment of the present application are described below with reference to fig. 1 to 16.

As shown in fig. 4, 5, 6, 13, 14, and 15, a camera module 100 according to some embodiments of the present application includes: an image sensor 110; a driving member 120; the lens assembly 170 is connected with the driving member 120, the lens assembly 170 comprises a lens portion 172, the lens portion 172 is provided with a first light surface 176 and a second light surface 174, and the first light surface 176 and the second light surface 174 are correspondingly arranged; the driving member 120 is configured to drive the lens assembly 170 to rotate, so that the first light surface 176 is disposed corresponding to the image sensor 110, or the second light surface 174 is disposed corresponding to the image sensor 110.

In this embodiment, the camera module 100 includes an image sensor 110, a driver 120, and a lens assembly 170. The lens assembly 170 includes a lens portion 172, the lens portion 172 having oppositely disposed first and second light surfaces 176 and 174.

In particular, with the structure of the lens assembly 170 unchanged, increasing the image distance may increase the magnification of the image. The reverse connection of the lens assembly 170 can effectively increase the image distance. When the lens assembly 170 is reversely connected, the image sensor 110 is at a larger distance from the principal object plane 270, and at this time, the image distance of the camera module 100 is larger, and the corresponding magnification is larger.

When the lens assembly 170 is in the normal state, the first light surface 176 of the lens portion 172 is disposed corresponding to the image sensor 110. At this time, the camera module 100 can realize a normal wide-angle imaging function.

When the driving member 120 drives the lens assembly 170 to rotate, the matching positions of the lens portion 172 and the image sensor 110 are adjusted, so that the second light surface 174 of the lens portion 172 is disposed corresponding to the image sensor 110, and the lens assembly 170 can realize light path inversion after being turned over, so as to change the positions of the image plane 280 and the object plane 270. High magnification, high pixel macro shooting effect with the lens assembly 170 is achieved. Wherein the arrows in fig. 5 indicate the rotational direction of the lead screw 124 and the lens assembly 170.

That is, the driving member 120 adjusts the matching position of the lens assembly 170 and the image sensor 110 without adding an additional macro camera, so that the dual-purpose use function of the camera module 100 can be realized. That is, when the first light surface 176 of the lens portion 172 is disposed corresponding to the image sensor 110, the camera module 100 has a wide-angle image capturing function, and when the second light surface 174 of the lens portion 172 is disposed corresponding to the image sensor 110, the camera module 100 has a macro image capturing function, so as to achieve high magnification and high pixel macro capturing effect by using the wide-angle lens assembly 170. A camera module 100 has wide angle function of making a video recording and the function of making a video recording of macro concurrently, should set up when guaranteeing wide angle and make a video recording with the effect of making a video recording of macro, saved a dedicated camera module 100 of making a video recording of macro, can save the inside space of stacking of electronic equipment 300, reduce the occupancy rate of camera module 100 to electronic equipment 300 inner space, can reduce the manufacturing cost of product, promoted the performance and the market competition of product.

Specifically, the distance of the photographed object from the object-side principal plane 270 of the lens 290 is referred to as an object distance. The distance of the photosensitive element image sensor 110 from the image-side principal plane 280 is referred to as the image distance. The magnification m of the object imaging is proportional to the image distance v, and the magnification m of the object imaging is inversely proportional to the focal length f, wherein,increasing the image distance may increase the magnification of the image without changing the configuration of the lens assembly 170. The reverse connection of the lens assembly 170 can effectively increase the image distance.

In a typical lens 290, the principal plane need not be inside the lens 290, where the distance of the image-side principal plane 280 to the image sensor 110 is substantially close to the focal length.

As shown in fig. 1, the focal length of the wide-angle camera module 100 is generally small, and the image-side principal plane 280 is located between the lens 290 and the image sensor 110. The distance from the object-side principal plane 270 to the image-side principal plane 280 is less than or equal to the lens 290 length.

As shown in fig. 2, when the lens 290 is reversely connected, the primary image side principal plane is on the side close to the object, and the primary object side principal plane is on the side close to the image sensor 110. As can be seen from comparing fig. 1, at this time, the distance from the image sensor 110 to the primary object plane (now the primary image plane) is larger, that is, the image distance of the camera module 100 is larger, so that the corresponding magnification is larger.

As shown in fig. 3, the lens portion 172 is a wide angle lens portion. The optic portion 172 includes a first convex lens 178, a concave lens 180, and a second convex lens 182, which are a cauchy three-piece structure. After the lens assembly 170 is flipped, the lens portion 172 is flipped as well to effect a reversal of the optical path, transforming the position of the image-side principal plane 280 and the object-side principal plane 270.

Based on the above-mentioned imaging magnification principle, the present application drives the lens assembly 170 to rotate through the driving member 120, so as to realize the forward and reverse connection of the lens assembly 170. The macro function and the wide-angle function share the same camera module 100, that is, one camera module 100 realizes wide-angle and macro shooting at the same time, so that shooting capability of the camera module 100 is fully exerted, and internal stacking space of the electronic device 300 is saved.

In some embodiments, as shown in fig. 3 and 12, the optic portion 172 includes a first convex lens 178, a concave lens 180, and a second convex lens 182 along the direction of the first light surface 176 to the second light surface 174.

In a particular application, the optic portion 172 includes a first convex lens 178, a concave lens 180, and a second convex lens 182, and defines a stacked relationship of the first convex lens 178, the concave lens 180, and the second convex lens 182 such that the concave lens 180 is positioned between the first convex lens 178 and the second convex lens 182 along the direction of the first light surface 176 to the second light surface 174.

It will be appreciated that when the lens assembly 170 is in the on state, light propagates from the second light surface 174 to the first light surface 176 and then to the image sensor 110.

In addition, since the straight tooth segment 130 of the first gear 128 is engaged with the lead screw 124, the first gear 128 may rotate.
