Description

Technical Field

[0001] This utility model relates to the field of camera-assisted light imaging technology, specifically to an imaging component for a camera. Background Technology

[0002] The camera lens can only provide light of a fixed wavelength range to the sensor for imaging. Therefore, how to enable the camera to support imaging of light of different wavelengths has become a technical problem to be solved in the prior art. The above application documents achieve imaging of light of different wavelengths by setting up a filter lens.

[0003] A search revealed that patent application number 201921044824.3 discloses an imaging component for a camera and a camera. Based on this invention, the imaging component of the camera may include a filter assembly arranged between the lens and the sensing module. This filter assembly comprises at least two mutually coupled filter elements with different filtering properties. By driving the rotation of the filter color wheel, at least two filter elements can cyclically pass through the imaging field of view. Therefore, based on a single lens and a single sensing module hardware configuration, the camera can support light imaging in different wavelength bands.

[0004] The aforementioned application documents achieve corresponding light imaging through the setting of various components, but the overall structure is complex and the size is large. Existing cameras are all handheld, and the aforementioned components are not suitable, nor is it convenient to adjust the specifications of the two sets of filter lenses.

[0005] Therefore, we propose an imaging component for a camera. Utility Model Content

[0019] This invention provides an imaging component for a camera. It has the following advantages:

[0020] The imaging component of this camera, through the lens barrel and the inner secondary lens and main lens, can adjust the distance between the secondary lens and the lens barrel by driving the electric cylinder component, thereby enabling auxiliary imaging of the camera from the front and ensuring the light imaging effect. At the same time, the overall structure is simple and can be flexibly assembled according to needs, ensuring the imaging effect of handheld shooting, and solving the problem that existing devices are difficult to perform auxiliary light imaging of handheld cameras according to needs.
