Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention provides a camera module, as shown in fig. 1, including: the single camera 1 is arranged on a reflector 2 in front of the single camera 1; wherein the content of the first and second substances,
one surface of the reflector 2 facing the single camera 1 is a reflecting surface 21, and the reflecting surface is used for reflecting light rays of objects around the single camera 1 to the single camera 1.
In the camera module provided by the embodiment of the invention, the reflector is arranged in front of the common single camera, and light rays of objects around the single camera are reflected by the reflecting surface of the reflector and irradiated into the single camera, so that images beyond the original angle of view of the single camera are captured, and the function of panoramic shooting is further realized.
It should be noted that, comparing the camera module of the present invention with the traditional single fisheye panoramic camera module, the single fisheye panoramic camera has a special lens design, the lens is hemispherical and protrudes outwards, such a lens structure can refract the light irradiated on the lens around the lens into the camera module through the lens, thereby realizing panoramic shooting; the invention utilizes the reflection principle of the mirror surface, a reflector is arranged above the single camera with the common view angle, and the light rays around the lens irradiate the inside of the lens through the reflection of the mirror surface, thereby realizing the panoramic image similar to the single fisheye panoramic camera module.
In a specific implementation, in the above-mentioned camera module according to an embodiment of the present invention, as shown in fig. 1 to 3, the reflecting surface 21 may be a convex curved surface, that is, the reflecting surface 21 faces the single camera 1 and is convex. Specifically, as shown in fig. 1, the cross section of the reflecting surface 21 may be parabolic. Preferably, the cross section of the reflecting surface can be in a circular arc shape, that is, the reflecting mirror can be in a spherical crown shape or a hemispherical shape, and the manufacturing process is simple. Of course, the shape of the reflecting surface may be other shapes, and the specific shape may be determined according to the actual situation, which is not described herein.
Further, in the above-mentioned camera module according to the embodiment of the present invention, as shown in fig. 1 and fig. 2, a surface of the reflector 2 away from the single camera 1 may be a circular plane 22.
Furthermore, in the above-mentioned camera module according to the embodiment of the present invention, since the part of the reflecting surface directly facing the opposite camera is not effectively reflected, as shown in fig. 2 and 3, the middle area of the reflector 2 may be provided with a through hole 23 extending along the plane 22 toward the reflecting surface 21; the through hole 23 may be aligned with the single camera 1. In practical application, the size of the opening of the through hole can be equal to the size of the single camera, that is, a hole close to the size of the camera can be dug in the middle of the reflecting surface, so that the projection of the single camera in the reflected image can be prevented.
In particular, in implementation, in order to further effectively prevent the projection of the camera from occurring in the reflected image, the side surface of the through hole may have a light absorbing material; preferably, the light absorbing material may be a black, highly light absorbing material.
In addition, in the above-mentioned camera module according to the embodiment of the present invention, as shown in fig. 1 to 3, a set distance is provided between the reflecting mirror 2 and the single camera 1; the set distance may be determined by the reflection effect of the reflection surface, and is not limited herein. And because the reflector and the single camera have a set distance, the reflector can be selectively installed in front of the single camera through a transparent cylindrical cover in the installation mode, so that the imaging quality is not influenced.
The embodiment of the invention provides a camera module, which comprises: the single camera is arranged on the reflector in front of the single camera; the reflecting mirror is a reflecting surface facing one surface of the single camera and used for reflecting light rays of objects around the single camera into the single camera. The reflector is arranged in front of the common single camera, and light rays of objects around the single camera are reflected by the reflecting surface of the reflector and are irradiated into the single camera, so that images beyond the original field angle of the single camera are captured, the panoramic shooting function is further realized, the operation is simple, the cost is low, and the imaging quality is better.
