Embodiment 1

[0050] like image 3 As shown, Embodiment 1 of the present invention proposes a camera assembly 300, which includes a first lens group 310, a switchable slit 320, a focusing element 330, a dispersion element 340, an infrared filter 350, and a second lens group 360 , an image sensor 370 , a first switching component 380 and a second switching component 390 .

[0051] Wherein, the first lens group 310 is mainly used to collect external light for imaging processing. Specifically, the lens of the first lens group 310 is a convex lens structure.

[0052] The switchable slit 320 is mainly used to cut into the front focal plane of the lens of the first lens group 310, so that the light emitted by the first lens group 310 becomes a parallel light. Specifically, the switchable slit 320 includes a slit main body 321 and a slit moving motor 322, and the slit moving motor 322 is used to drive the slit main body 321 to cut into or out of the lens front focal plane of the first lens group...

Embodiment 2

[0063] like Image 6 As shown, Embodiment 2 of the present invention proposes a camera assembly control method, which is applied to the camera assembly 300 in Embodiment 1 of the present invention. The camera assembly control method includes the following steps:

[0064] Step S1: The camera assembly switches to the first working mode, the switchable slit cuts out the front focal plane of the lens of the first lens group, switches the focusing element and the infrared filter to work, and the image sensor collects the light from the infrared filter for shooting imaging.

[0065] Specifically, such as image 3 and Figure 4 As shown, when the camera assembly 300 switches the first working mode, that is, when it is used as a camera, the slit moving motor 322 drives the slit main body 321 to cut out the lens front focal plane of the first lens group 310, and the first switching The control element of the assembly 380 will control the focus element 330 to adjust the lens focal le...

Embodiment 3

[0069] Embodiment 3 of the present invention proposes a mobile terminal. The mobile terminal includes the camera assembly 300 in Embodiment 1. The camera assembly 300 includes a first lens group 310, a switchable slit 320, a focusing element 330, a dispersion element 340, an infrared The optical filter 350 , the second lens group 360 , the image sensor 370 , the first switching component 380 and the second switching component 390 .

[0070] Wherein, the first lens group 310 is mainly used to collect external light for imaging processing. Specifically, the lens of the first lens group 310 is a convex lens structure.

[0071] The switchable slit 320 is mainly used to cut into the front focal plane of the lens of the first lens group 310, so that the light emitted by the first lens group 310 becomes a parallel light. Specifically, the switchable slit 320 includes a slit main body 321 and a slit moving motor 322, and the slit moving motor 322 is used to drive the slit main body 3...

Abstract

The invention discloses a camera component, a control method thereof and a mobile terminal, belonging to the technical field of mobile terminal cameras. The camera assembly includes: a first lens group, which is used to collect external light for imaging processing; a switchable slit, which is used to cut into the front focal plane of the lens of the first lens group, so that the light emitted by the first lens group becomes Parallel rays; focusing element, used to adjust the lens focal length of the first lens group, so that the image of the first lens group is clear; dispersion element, used to separate the rays of different wavelengths in the parallel rays; infrared filter, used for the first lens group The light from the first lens group is processed by infrared and stray light filtering; the second lens group is used to focus the light from the dispersion element; the image sensor is used to collect the light from the infrared filter for imaging or acquisition The light from the second lens group performs spectral imaging. The camera assembly of the present invention has the functions of ordinary camera and spectrometer at the same time.

Description

technical field [0001] The invention relates to the technical field of mobile terminal cameras, in particular to a camera assembly and a mobile terminal with the camera assembly. Background technique [0002] On the one hand, a spectrometer is a scientific instrument that decomposes light with complex components into spectral lines. It can qualitatively and quantitatively detect the main components and elements of various substances, so it can be easily applied to food safety testing in daily life scenarios. aspect. For example, you can know whether there are harmful substances in drinking water, whether there are additives in food, whether there are pesticides on the skin of fruits, and so on. However, the current spectrometer exists as an independent instrument, and is bulky and expensive. It is mostly used in scientific research and is not suitable for use in daily life. On the other hand, with the increasingly higher requirements for portability and ultra-thin and ultr...
