[0064] like Figure 9 to Figure 13 As shown, on the basis of the first embodiment, the light reflection mechanism 2 includes a first reflection part 25 and a second reflection part 26, and the first refraction surface 21, the first reflection surface 22 and the second refraction surface 23 are all The second reflection surface 24 is disposed on the second reflection portion 26 and disposed on the first reflection portion 25 .

[0065] The difference between the embodiment of the present invention and the first embodiment is that the light reflection mechanism 2 in the first embodiment adopts an integral structure, while the embodiment of the present invention splits the light reflection mechanism 2 into two reflection parts.

[0066] Due to the adoption of the above-mentioned different technical solutions, the embodiment of the present invention has the following further beneficial effects compared with the first embodiment:

[0067] On the one hand, the integral light refrac...

[0081] like Figure 14 to Figure 17 As shown, on the basis of the first embodiment or the second embodiment, the camera also includes a first barrel 3 and a second barrel 4; the lens 1 includes N lenses 11, and the light refraction mechanism 2 and N lenses 11 The first M lenses 11 are assembled in the first barrel 3, and the lenses 11 of the N lenses 11 except the first M lenses 11 are assembled in the second barrel 4; the first barrel 3 is fixedly arranged in the second barrel 3. On the barrel 4; N is a positive integer greater than or equal to 2, M is a positive integer greater than or equal to 1, and N is greater than M.

[0082] in, Figure 14 It shows an embodiment in which the lens 1 includes four lenses 11 , the light reflection mechanism 2 and the first lens 11 are assembled together in the first cylinder 3 , and the remaining three lenses 11 are jointly assembled in the second cylinder 4 . Figure 16 It shows an embodiment that the lens 1 includes two lenses 11 , th...

Abstract

The invention provides a camera and a mobile terminal. The camera comprises a lens and a light ray refracting-reflecting mechanism assembled on the lens; the light ray refracting-reflecting mechanismcomprises a first side and a second side arranged oppositely; a first refracting surface and a first reflecting surface are arranged on the first side of the light ray refracting-reflecting mechanism;the first reflecting surface is arranged in the middle region of the first side; the first refracting surface is arranged around the first reflecting surface; a second refracting surface and a secondreflecting surface are arranged on the second side of the light ray refracting-reflecting mechanism; the second refracting surface is arranged in the middle region of the second side; the second reflecting surface is arranged around the second refracting surface; the second refracting surface faces the lens; and external light ray comes from the first refracting surface to the light ray refracting-reflecting mechanism and goes out of the second refracting surface. By virtue of the light ray refracting-reflecting mechanism, the light ray path propagating direction can be converted from a Z direction into an XY direction, so that a smaller field angle can be obtained under the same camera height condition, thereby improving the telescoping effect of the camera.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a camera and a mobile terminal. Background technique [0002] At present, most of the mobile terminals are equipped with a camera, so as to realize the function of taking pictures and taking pictures. At present, the field of view of the camera lens installed on the mobile terminal is generally 70° to 80°. When shooting a distant object and wanting to highlight the subject, it is necessary to reduce the field of view by zooming, which will reduce the image pixels. [0003] In order to enhance the telephoto effect of the camera, it is necessary to use a telephoto lens with a small field of view. However, due to the limitation of the height and space of the mobile terminal, the field of view of the telephoto lens is at most 40° to 60°, making the telephoto lens of the camera The effect is limited. [0004] It can be seen that the existing mobile terminal has the problem ...
