Problems solved by technology
[0002] The lens of the current camera is difficult to separate the views of different perspectives from the light. It can only capture the view of a single perspective, and the shooting effect is relatively single.
However, if multiple lenses are used to separate multiple different angles of view from the light, multiple lenses need to be arranged side by side and ensure that multiple lenses are located in the same plane. fulfil requirements

Embodiment Construction
[0024] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.
[0025] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, this embodiment provides a lens group that can separate views of different viewing angles from light, including a lens body, a first lens group 1 is arranged inside the lens body, and the inner edge of the lens body is far away from the first lens group 1 The direction of the second lens group 2, the adjustment lens 3 and the CMOS image sensor 4 are also arranged in sequence. Wherein, the second lens group 2 includes a mount on which two Fresnel lenses 21 arranged side by side are arranged, and the distance between each Fresnel lens 21 and t...

The invention relates to a lens group capable of separating views of different angles of view from light, comprising a lens body, a first lens group is arranged inside the lens body, and the lens body is sequentially arranged in a direction away from the first lens group A second lens group, an adjustment lens, and a CMOS image sensor are provided; the second lens group includes a mounting frame, and at least two Fresnel lenses are arranged on the mounting frame, and each of the Fresnel lenses is arranged side by side, and each The distance between the Fresnel lens and the first lens group is equal. In the present invention, the light emitted from the first lens group is incident on the second lens group, and each Fresnel lens of the second lens group can separate the view of a viewing angle from the light, and the present invention can separate the view from the light Views of at least two viewing angles, the light emitted from the Fresnel lens is adjusted by the adjustment lens and projected on the CMOS image sensor for imaging, presenting the viewing effect of multiple viewing angles.
Description
technical field [0001] The invention relates to the technical field of shooting structures, in particular to a lens group capable of separating views of different viewing angles from light rays. Background technique [0002] It is difficult for the lens of the current camera to separate the views of different angles of view from the light. It can only capture the view of a single angle of view, and the shooting effect is relatively single. However, if multiple lenses are used to separate multiple different angles of view from the light, multiple lenses need to be arranged side by side and ensure that multiple lenses are located in the same plane. fulfil requirements. Contents of the invention [0003] Aiming at the defects in the prior art, the technical problem to be solved by the present invention is to provide a lens group that can separate views of different viewing angles from light rays. It arranges several Fresnel lenses side by side, which can separate the views f...
