Along with the function upgrade of products, the camera module has different lenses, so that users can shoot and record objects in different ranges and different distances conveniently. In the prior art, each camera is provided with a corresponding sensor.

The application provides a camera module, has two different camera lenses at least, and the image of shooing through two camera lenses is handled by same sensor for the image that obtains can be unanimous at white balance, color style and picture quality.

Specifically, as shown in fig. 1 or 2, the present application provides a camera module, including:

a housing 100, wherein the housing 100 has a side wall 100a and an end wall 100b, and the side wall 100a and the end wall 100b enclose a receiving space 100 c;

a sensor 200, said sensor 200 being disposed on said end wall 100 b;

a first lens 300 and a second lens 400, wherein the first lens 300 and the second lens 400 are arranged on the sidewall 100a at intervals; and

a first prism 500 and a second prism 600, wherein the first prism 500 and the second prism 600 are arranged in the accommodating space 100c at intervals and connected with the side wall 100 a; the first light incident surface 500a of the first prism 500 is arranged corresponding to the first lens 300, and the first light incident surface 500a of the second prism 600 is arranged corresponding to the second lens 400; the first light emitting surface 500b of the first prism 500 and the second light emitting surface 600b of the second prism 600 face the sensor 200.

In the technical solution of the embodiment of the present application, the housing 100 has a side wall 100a and an end wall 100b, and the end wall 100b and the side wall 100a enclose to form an accommodating space 100 c. The sensor 200 is disposed on the end wall 100 b. The first lens 300 and the second lens 400 are disposed on the sidewall 100a with a space therebetween. The first prism 500 and the second prism 600 are disposed inside the accommodating space 100c with an interval therebetween, and are connected to the sidewall 100 a. The first light incident surface 500a of the first prism 500 is arranged corresponding to the first lens 300, and the first light incident surface 500a of the second prism 600 is arranged corresponding to the second lens 400; the first light emitting surface 500b of the first prism 500 and the second light emitting surface 600b of the second prism 600 face the sensor 200. Therefore, the light passing through the first lens 300 enters the first light incident surface 500a and then exits from the first light exiting surface 500b, enters the sensor 200, and is processed by the sensor 200 to obtain an image collected by the first lens 300; the light rays passing through the second lens 400 enter the second light incident surface 600a and then exit from the second light exiting surface 600b, enter the sensor 200, and are processed by the sensor 200 to obtain an image collected by the second lens 400; since the first lens 300 and the second lens 400 of the present disclosure correspond to the same sensor 200, the obtained images can be uniform in white balance, color tone, and image quality.

The sensor 200 is an imaging sensor 200 for receiving light and imaging based on the light. In general, the sensor 200 may be a CCD (Charge-Coupled Device) image sensor 200 or a cmos (complementary Metal Oxide semiconductor) image sensor 200.

In the implementation process, when the first lens 300 is taking a picture, the liquid crystal controls the light incident lens of the second lens 400 to be in a light blocking state, and at this time, light cannot enter the camera module through the second lens 400. The light of the first lens 300 enters the first prism 500, passes through the first light incident surface 500a, is totally reflected on the first reflection surface, and then passes through the first light emitting surface 500 b; since the second prism 600 is disposed between the first prism 500 and the sensor 200, the light is transmitted into the second prism 600 and then emitted to the sensor 200 by the second light emitting surface 600b of the second prism 600, and is imaged by the sensor 200.

Or, when the second lens 400 is taking a picture, the liquid crystal controls the light incident lens of the first lens 300 to be in a light blocking state, and at this time, the light cannot enter the camera module through the first lens 300. The light of the second lens 400 enters the second prism 600, passes through the second light incident surface 600a, then is totally reflected on the second reflection surface, then passes through the second light emitting surface 600b, then is emitted to the sensor 200, and is imaged by the sensor 200.

As an alternative implementation of the above embodiment, the first lens 300 and the second lens 400 are located on the same side of the housing 100. Namely: the objects shot by the first lens 300 and the second lens 400 are located on the same side of the camera module, and when the camera module is used, a user selects the first lens 300 or the second lens 400 to shoot according to the range of the objects on the same side to be shot, so that the camera module is convenient to use.

As an optional implementation of the above embodiment, the focal length of the first lens 300 is greater than the focal length of the second lens 400; for example, the first lens 300 may be a telephoto lens and the second lens 400 may be a portrait lens (or a standard lens). Since the focal length of the first lens 300 is greater than that of the second lens 400, the second lens 400 and the first lens 300 are sequentially spaced on the side wall 100a in a direction in which the end wall 100b having the sensor 200 is directed to the other end wall 100b of the housing 100, so that the imaging quality is reliable. In general, the housing 100 of the camera module is formed to extend in the axial direction, and then the axial distance between the second lens 400 and the sensor 200 is smaller than the axial distance between the first lens 300 and the sensor 200.

The first lens assembly 700 includes concave and convex lenses disposed in spaced relation. The light is converged by the convex lens and then emitted to the sensor 200 by the concave lens, that is: the concave lens of the first lens assembly 700 is closer to the sensor 200 and the convex lens of the first lens assembly 700 is closer to the second prism 600. Or the light rays are diverged by the concave lens and then converged by the convex lens to be emitted to the sensor 200, that is: the convex lens of the first lens assembly 700 is closer to the sensor 200 and the concave lens of the first lens assembly 700 is closer to the second prism 600. Generally, the first lens assembly 700 can be glued to the sidewall 100a and located in the receiving space 100 c.

For example, the second lens assembly 800 includes spaced apart concave and convex lenses. The light is converged by the convex lens and then divergently emitted to the second prism 600 by the concave lens, that is: the concave lens of the second lens assembly 800 is closer to the second prism 600 and the convex lens of the first lens assembly 700 is closer to the first prism 500. Or the light rays are diverged by the concave lens and then converged by the convex lens to be emitted to the sensor 200, that is: the convex lens of the second lens assembly 800 is closer to the second prism 600 and the concave lens of the first lens assembly 700 is closer to the first prism 500.

In general, the housing 100 of the camera module is formed to extend in the axial direction, and then the axial distance between the third lens 900 and the sensor 200 is smaller than the axial distance between the second lens 400 and the sensor 200.

When the third lens 900 is used, the liquid crystal controls the light incident lens of the second lens 400 and the light incident lens of the third lens 900 to be in a light blocking state, light enters from the third lens 900, then enters the third prism 1000 through the third light incident surface 1000a of the third lens 900, and then exits through the third light emitting surface 1000b of the third lens 900, and then enters the sensor 200 through the first lens assembly 700 after convergence-divergence or divergence-convergence, and is imaged by the sensor 200.
