Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

When terminal products such as mobile phones are used for shooting, users often need to amplify and shoot images under the influence of shooting distance or composition design, however, as the amplification factor is increased, the image resolving power is seriously sacrificed by pure digital zooming, so that more and more mobile phone camera modules are added with an optical zooming function, the function optically ensures that images of a plurality of fixed focal sections can be acquired, and the image resolving power is maintained while a wider zooming range is covered by combining a digital zooming algorithm. At present, a relatively wide optical zoom hardware scheme used on a mobile phone is a dual fixed focus module structure formed by combining a main camera with a standard focal length and an auxiliary camera with a long focal length, but the expansibility of the scheme is poor, and when hardware is needed to acquire images of more focal lengths, more camera positions, corresponding sensors and corresponding driving circuits must be reserved on a mobile phone shell, so that the cost is increased. Therefore, the embodiment of the application provides a camera module, which can realize an optical zoom function on the basis of adopting one camera, so that the cost is low, and the appearance quality of the camera module cannot be influenced when the camera module is integrated on small-sized terminal products such as a mobile phone.

In the camera module in the embodiment of the application can be applied to electronic equipment, the electronic equipment can be a mobile phone or a tablet computer and other common terminals in the prior art. Referring to fig. 1, a camera module 100 according to an embodiment of the present disclosure includes a fixed focus lens group 10 and a photosensitive element 20, wherein the fixed focus lens group has a light entering side 11 and a light exiting side 12, and the photosensitive element 20 is located on the light exiting side 12, so that light emitted from the light exiting side 12 of the fixed focus lens group 10 can be projected onto the photosensitive element 20. In a specific arrangement, the fixed-focus lens group 10 may include a plurality of lenses and a carrier for mounting the lenses, and the carrier may be provided with a plurality of positions for fixing the lenses in the corresponding positions at intervals. The light sensing element 20 may be a CMOS (metal-oxide semiconductor) image sensor or a CCD (charge coupled device) image sensor for performing photoelectric conversion and a/D (analog/digital) conversion on an optical signal of incident light to output image data for display by the display unit.

In this embodiment, the camera module may further include a light turning element 30, where the light turning element 30 is located on one side of the light entering side 11, and is configured to turn light entering the camera module and enter the light entering side of the fixed focus lens group, specifically, light may enter the camera module along the light entering axis of the camera module, and after turning through the light turning element, light entering side of the fixed focus lens group is entered along the optical axis of the fixed focus lens group, and during specific design, the light entering axis of the camera module may be perpendicular to the optical axis of the fixed focus lens group, so that the camera module constitutes a module having a periscopic structure, and thus, the camera module may be applied to an electronic device adopting an ultra-thin design, and an application scene thereof may be expanded. It should be noted that the light rays incident along the light inlet axis can be understood as light rays incident into the camera module by taking the light inlet axis as a center, and the light rays can be parallel to the light inlet axis and also can form a certain included angle with the light inlet axis; similarly, the light ray incident along the optical axis of the fixed focus lens group can be understood as the light ray incident into the light entrance side with the optical axis of the fixed focus lens group as the center, and the light ray and the optical axis of the fixed focus lens group can be parallel or have a certain included angle.

In a specific arrangement, the light diverting element 30 may include a base 31, a mounting portion 32 and a light diverting portion 33, wherein the mounting portion 32 is mounted on the base 31 and the light diverting portion 33 is mounted on the mounting portion 32. The light diverting part 33 may be a prism or a plane mirror, for example, in the embodiment shown in fig. 1 and 2, the light diverting part 33 is a triangular prism, and light can enter from one of the right-angle surfaces of the triangular prism and then exit from the other right-angle surface after being reflected; in the embodiment shown in fig. 3 and 4, the light diverting part 33 is a plane mirror, and the plane mirror can directly reflect the incident light to divert the incident light.

Referring to fig. 5, the light diverting element 30 may further include a first rotating shaft 34 and a second rotating shaft 35, wherein the extending direction of the first rotating shaft 34 is parallel to the light inlet axis (i.e., z-axis direction), the extending direction of the second rotating shaft 35 is perpendicular to the light inlet axis and the optical axis of the fixed focus lens group 10 (i.e., y-axis direction), the mounting portion 32 is rotatably connected to the base 31 through the first rotating shaft 34, and the light diverting portion 33 is rotatably connected to the mounting portion 32 through the second rotating shaft 35. In this way, the mounting portion 32 and the light diverting portion 33 mounted thereon can be rotated about the z-axis direction by the first rotating shaft 34 to compensate for the shift of the light in the y-axis direction due to the shake, so that the camera module realizes optical anti-shake in the y-axis direction; the light diverting part 32 can rotate around the y-axis direction by the second rotating shaft 35 to compensate the deviation of the light in the z-axis direction due to the shake, so that the camera module realizes the optical anti-shake in the z-axis direction.

It can be understood that, in other embodiments of the present application, the extending direction of the first rotating shaft may also be set to be perpendicular to the light entering axis and the optical axis of the fixed-focus lens group (i.e., the y-axis direction), and the extending direction of the second rotating shaft may also be set to be parallel to the light entering axis (i.e., the z-axis direction), so that optical anti-shake of the camera module in the z-axis direction and the y-axis direction can also be achieved, and details are not described here.

Wherein, M is the zoom multiple that can be realized when the a-fold fixed-focus lens assembly 10 and the B-fold variable-focus lens assembly 51 are combined for use, the values of M and a can be determined at the beginning of the design according to the actual use requirement of the camera module, and the value of B can be determined by the values of both M and a and the distance between the second working position 42 and the photosensitive element 20.

The driving mode has high reliability, and the volume of each element can be controlled in a small size, so that the volume of the whole driving part 52 is relatively reduced, and the occupied space of the camera module is saved.
